It has been demonstrated that the Agaricus blazei Murill (ABM) mushroom, which primarily consists of polysaccharides, possesses anti-tumor activities. However, the mechanisms by which ABM inhibits human hepatocellular carcinoma growth remain unknown. Our study demonstrates that ABM acts as an enhancer to sensitize doxorubicin (Dox)-mediated apoptotic signaling, and this sensitization can be achieved by enhancing intracellular Dox accumulation via the inhibition of NFκB activity. These findings suggest that ABM, when combined with low doses of Dox, has the potential to provide more efficient therapeutic effects against drug-resistant human hepatocellular carcinoma.

The effects of F III-2-b (Agaricus blazei Murill polysaccharide) with or without 5-fluorouracil (5-FU) on immune responses were investigated in Meth A tumor-bearing and normal mice. The i.p. administration of F III-2-b (10 mg/kg/day x 30) moderately inhibited the growth of Meth A tumor cells implanted s.c. in mice. Development of implanted tumors was strongly inhibited by the combination of F III-2-b and 5-FU. The picryl chloride-induced delayed type hypersensitivity (PC-DTH) response in mice was depressed after the implantation of tumor and treatment with 5-FU. F III-2-b restored the suppression of PC-DTH by 5-FU, but did not increase the PC-DTH of normal mice. F III-2-b not only enhanced the degree of spleen cell-mediated sheep red blood cells (SRBC) hemolysis (quantitative hemolysis of SRBC), the indexes of the spleen and thymus, and the number of spleen cells but also restored the suppressive effect of 5-FU. In the group receiving F III-2-b, the percentages of splenic Thy1.2-, L3T4- and asialo GM1-positive cells were significantly increased as compared with the tumor-bearing mice treated with saline. Furthermore, the L3T4+/Lyt2+ ratio showed a tendency to increase, and the Lyt2+ ratio was markedly decreased. These results suggest that the antitumor effect of F III-2-b may be correlated with the changing pattern of the Thy1.2-, L3T4- and asialo GM1-positive cells.

BACKGROUND: Ingestion of AndoSanTM, based on the mushroom Agaricus blazei Murill, has previously shown an anti-inflammatory effect through reduction of pro-inflammatory cytokines in healthy individuals and patients with Crohn's disease (CD). In this randomized single-blinded placebo-controlled study we examined whether intake of AndoSanTM also resulted in clinical effects. METHODS AND FINDINGS: 50 patients with symptomatic CD were randomized for oral daily consumption of AndoSanTM or placebo for a 21-day experimental period, in this per-protocol study. Patients reported validated scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSanTM group (n = 25) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.52 (4.64-6.40), 4.48 (3.69-5.27) and 4.08 (3.22-4.94) (p<0,001). We found significant improvements in symptom score for both genders in the AndoSanTM group, and no significant changes in the placebo (n = 25) group. There were however no significant differences between the groups (p = 0.106), although a marginal effect in symptom score for men (p = 0.054). There were comparable improvements in physical, mental and total fatigue for both groups. HRQoL versus baseline were at day 21 improved for bodily pain and vitality in the AndoSanTM group and for vitality and social functioning in the placebo group. No crucial changes in general blood samples and fecal calprotectin were detected. CONCLUSIONS: The results from this single-blinded randomized clinical trial shows significant improvement on symptoms, for both genders, in the AndoSanTM group, but no significant differences between the study groups. The results on fatigue, HRQoL, fecal calprotectin and blood samples were quite similar compared with placebo. The patients did not report any harms or unintended effects of AndoSanTM. CD patients with mild to moderate symptoms may have beneficiary effects of AndoSanTM as a safe supplement in addition to conventional medication. TRIAL REGISTRATION: ClinicalTrials.gov NCT01496053.

BACKGROUND: Ingestion of AndoSan™, based on the mushroom Agaricus blazei Murill, has previously been shown to exhibit anti-inflammatory effects because of reduction of pro-inflammatory cytokines in healthy individuals and patients with ulcerative colitis. In this randomized single-blinded placebo controlled study we examined whether intake of AndoSan™ also resulted in clinical effects. METHODS AND FINDINGS: 50 patients with symptomatic ulcerative colitis were block-randomized and blinded for oral daily intake of AndoSan™ or placebo for the 21 days' experimental period. The patients reported scores for symptoms, fatigue and health related quality of life (HRQoL) at days 0, 14 and 21. Fecal calprotectin and general blood parameters were also analyzed. In the AndoSan™ group (n = 24) symptoms improved from baseline (day 0) to days 14 and 21, with respective mean scores (95% CI) of 5.88 (4.92-6.83), 4.71 (3.90-5.52) (p = 0.002) and 4.50 (3.70-5.30) (p = 0.001). Corresponding improved mean scores (±SD) for total fatigue were 16.6 (5.59), 14.1 (4.50) (p = 0.001) and 15.1 (4.09) (p = 0.023). These scores in the placebo group (n = 26) were not improved. When comparing the two study groups using mixed model statistics, we found significant better scores for the AndoSan™-patients. HRQoL for dimensions bodily pain, vitality, social functioning and mental health improved in the AndoSan™ group. There were no alterations in general blood samples and fecal calprotectin. CONCLUSIONS: Beneficiary effects on symptoms, fatigue and HRQoL from AndoSan™ consumption were demonstrated in this per-protocol study, supporting its use as a supplement to conventional medication for patients with mild to moderate symptoms from ulcerative colitis. The patients did not report any harms or unintended effects of AndoSan™ in this study. TRIAL REGISTRATION: ClinicalTrials.gov NCT01496053.

OBJECTIVES: The aim of this preliminary clinical study was to assess if the daily intake of Agaricus blazei Murill (ABM) granulated powder (SSI Co., Ltd., Tokyo, Japan) for 6 months improved the quality of life (QOL) in cancer patients in remission. DESIGN: Open study. SETTING: Subjects diurnally took 1 (1.8 g; N=23), 2 (3.6 g; N=22), or 3 (5.4 g; N=22) packs/day orally for 6 months. MAIN OUTCOME MEASURES: The SF-8 Health Survey questionnaire was used to evaluate the QOL. The differences between the SF-8 baseline scores at the time of entry and 6-months after ABM treatment were evaluated. RESULTS: The results showed a significant improvement in QOL in both physical and mental components. More specifically, QOL effects of ABM in different genders showed males improved physical components, while females improved only mental components. QOL effects in the different age groups showed that ages 65 and under improved mental components, while ages 66 and older improved physical components. Furthermore, with respect to optimal dose effects of ABM with respect to QOL improvement, two packs per day for 6 months showed improvements in both physical and mental components. CONCLUSION: This preliminary longitudinal clinical study demonstrated that daily intake of ABM appears to improve both physical and mental components based on SF-8 qualimetric analysis.

BACKGROUND: Complementary and alternative medicine use in adults with type 2 diabetes is popular. Although most of the herbs and supplements appear to be safe, there is still insufficient evidence that demonstrates their definitive beneficial effects. This study was done to determine whether the supplement of Agaricus blazei Murill extract improves insulin resistance in type 2 diabetes. MATERIALS AND METHODS: This study was a clinical randomized, double-blind, placebo-controlled trial. Of a population of 536 registered diabetes patients with 72 subjects (1) aged between 20 and 75 years, (2) being Chinese, (3) having type 2 diabetes for more than 1 year, and (4) having been taking gliclazide and metformin for more than 6 months were enrolled in this study. The enrolled patients were randomly assigned to either receiving supplement of Agaricus blazei Murill (ABM) extract or placebo (cellulose) 1500 mg daily for 12 weeks. Homeostasis model assessment for insulin resistance (HOMA-IR) was used as the major outcome measurement. RESULTS: At the end of the study, subjects who received supplement of ABM extract (n = 29) showed significantly lower HOMA-IR index (3.6[standard deviation, 2.5] versus 6.6[standard deviation, 7.4], p = 0.04) than the control group (n = 31). The plasma adiponectin concentration increased 20.0(standard deviation, 40.7)% in the ABM group after 12 weeks of treatment, but decreased 12.0(20.0)% among those taking the placebo (p < 0.001). CONCLUSIONS: Supplement of ABM extract improves insulin resistance among subjects with type 2 diabetes. The increase in adiponectin concentration after taking AMB extract for 12 weeks might be the mechanism that brings the beneficial effect. Studies with longer periods of follow-up should be conducted in the future.

To investigate the effect of Agaricus mushroom meal on the energy metabolism in animal tissues; plasma glucose, triglyceride, cholesterol and immunoreactive insulin (IRI) concentrations and activities of enzymes related to energy metabolism in plasma and peripheral leukocytes were measured in Japanese Black WagyuxHolstein F1 calves supplemented with Agaricus blazei Murill (A. blazei) extract in milk-replacer at the dose of 60g/head/day for 4 weeks. Activities of malate dehydrogenase and aspartate aminotransferase in cytosol and glutamate dehydrogenase in mitochondria, and the malate dehydrogenase/lactate dehydrogenase ratio in cytosol in peripheral leukocytes of calves with A. blazei were significantly higher than those in control calves without A. blazei. It was concluded that supplementation of Agaricus mushroom meal extract was effective in activation of enzymes related to energy metabolism in peripheral leukocytes of calves.

Since Agaricus blazei Murill (AbM) extract reduced specific IgE and ameliorated a skewed Th1/Th2 balance in a mouse allergy model, it was tested in blood donors with self-reported, IgE-positive, birch pollen allergy and/or asthma. Sixty recruited donors were randomized in a placebo-controlled, double-blinded study with pre-seasonal, 7-week, oral supplementation with the AbM-based extract AndosanTM. Before and after the pollen season, questionnaires were answered for allergic rhino-conjunctivitis, asthma, and medication; serum IgE was measured, and Bet v 1-induced basophil activation was determined by CD63 expression. The reported general allergy and asthma symptoms and medication were significantly reduced in the AbM compared to the placebo group during pollen season. During the season, there was significant reduction in specific IgE anti-Bet v 1 and anti-t3 (birch pollen extract) levels in the AbM compared with the placebo group. While the maximal allergen concentrations needed for eliciting basophil activation before the season, changed significantly in the placebo group to lower concentrations (i.e., enhanced sensitization) after the season, these concentrations remained similar in the AndosanTM AbM extract group. Hence, the prophylactic effect of oral supplementation before the season with the AbM-based AndosanTM extract on aeroallergen-induced allergy was associated with reduced specific IgE levels during the season and basophils becoming less sensitive to allergen activation.

Ingestion of the Agaricus blazei Murill-based mushroom extract AndoSan™ has been shown in randomized placebo-controlled studies to improve symptoms in Crohn's disease (CD) and ulcerative colitis (UC) and also fatigue and quality of life in the latter patients. The aim was to examine whether this clinical impact of AndoSan™ intake could be explained by influence on foremost pro-inflammatory cytokines in the patients. Fifty patients with symptomatic UC and CD were randomized and blinded for oral daily intake of AndoSan™ or placebo. Blood samples taken before (visit 1) and after 21 days' (visit 3) consumption were analysed for cytokines IL-1ß, IL-2, IL-4-8, IL-10, IL-12-13, IL-17, G-CSF, GM-CSF, IFN-γ, MCP-1, MIP-1ß and TNF-α. Baseline cytokine levels were similar in CD and UC. In CD, cytokine levels at visit 1 versus visit 3 were unaltered within the AndoSan™ and the placebo groups. Only IL-2 was significantly reduced at visit 3 in the Andosan™ compared with the placebo group. However, when combining IL-1ß, IL-6 and G-CSF in the patients with CD, the cytokine levels were significantly lower in the AndoSanTM - versus the placebo group, visit 3. In UC, levels of IL-2, IL-5 and MIP-1ß were reduced within the AndoSan™ group. IL-5 was also reduced at visit 3 compared with placebo. Generally, the effect on reduction in systemic cytokine levels by consumption of AndoSan™ was limited and supported only marginally anti-inflammatory effects in these patients. Therefore, other explanations behind the clinical anti-inflammatory effects than the contribution of cytokines seem more pertinent, including anti-allergic and antioxidant activities. © 2016 The Foundation for the Scandinavian Journal of Immunology.

Forty patients with multiple myeloma scheduled to undergo high dose chemotherapy with autologous stem cell support were randomized in a double blinded fashion to receive adjuvant treatment with the mushroom extract AndoSan, containing 82% of Agaricus blazei Murrill (19 patients) or placebo (21 patients). Intake of the study product started on the day of stem cell mobilizing chemotherapy and continued until the end of aplasia after high dose chemotherapy, a period of about seven weeks. Thirty-three patients were evaluable for all study endpoints, while all 40 included patients were evaluable for survival endpoints. In the leukapheresis product harvested after stem cell mobilisation, increased percentages of Treg cells and plasmacytoid dendritic cells were found in patients receiving AndoSan. Also, in this group, a significant increase of serum levels of IL-1ra, IL-5, and IL-7 at the end of treatment was found. Whole genome microarray showed increased expression of immunoglobulin genes, Killer Immunoglobulin Receptor (KIR) genes, and HLA genes in the Agaricus group. Furthermore, AndoSan displayed a concentration dependent antiproliferative effect on mouse myeloma cells in vitro. There were no statistically significant differences in treatment response, overall survival, and time to new treatment. The study was registered with Clinicaltrials.gov NCT00970021.

There is scientific evidence to suggest that the medicinal mushroom Agaricus blazei Murrill (AbM) has immunomodulatory effects on cytokine synthesis, both in vitro and in vivo. This study was the first randomized, double-blind, placebo-controlled trial designed to investigate these purported actions in elderly women. The objective of this study was to ascertain the effects of AbM intake on serum levels of interleukin-6 (IL-6), interferon-gamma (IFN-γ) and tumour necrosis factor-alpha (TNF-α) in community-living seniors. The sample consisted of 57 elderly females who were carriers or homozygous for the majority allele of functional polymorphisms for the chosen cytokines. Subjects were randomly allocated to receive placebo (n = 29) or AbM dry extract (n = 28), 900 mg/day for 60 days. Body mass index, abdominal girth, body composition, blood pressure and cytokine (IL-6, IFN-γ, and TNF-α) levels were measured, and food intake was assessed as a possible confounder. Analysis of these parameters showed the sample was characterized by overweight and excess adiposity. After the study period, no changes from baseline were detectable for any parameter in either group. In this study, AbM extract had no modulating effect on IL-6, IFN-γ or TNF-α levels in elderly females. © 2011 The Authors. Scandinavian Journal of Immunology © 2011 Blackwell Publishing Ltd.

Background/Objectives: Surgical resection of non-small-cell lung cancer (NSCLC) often results in temporary suppression of natural killer cell activity (NKA), potentially increasing the risk of recurrence. This study aimed to evaluate whether multivitamin and mineral complexes containing Agaricus blazei could support postoperative immune recovery. Methods: In this randomized, double-blind, placebo-controlled multicenter pilot trial, 66 patients with stage I-III NSCLC received either a supplement or a placebo for 28 days post-surgery. NKA was assessed using an interferon-γ release assay preoperatively, on postoperative days (POD) 1-4, and on POD 30. Immune cell subsets, cytokine levels, clinical parameters, and quality of life were evaluated. Results: Both groups showed a postoperative decline in NKA, with recovery observed by POD 30. Although the increase in NKA was not statistically significant, the treatment group showed a greater relative recovery (17.8% vs. 9.9%, p = 0.104). Immune profiling demonstrated significantly better preservation of T cells (p = 0.026) and B cells (p = 0.001) as well as a greater reduction in monocytes (p = 0.031) in the treatment group. No signi

Chronic myeloid leukemia (CML) is a malignant hematological neoplasm. FA-2-b-β, extracted from Agaricus blazei Murrill, has demonstrated antitumor activity against multiple cancer types. Nevertheless, the specific pharmacodynamic components and molecular mechanisms of FA-2-b-β against CML remain to be elucidated. This study aimed to systematically investigate the mechanism of FA-2-b-β against CML through an integrated strategy combining liquid chromatography-tandem mass spectrometry (LC-MS/MS), network pharmacology prediction, and in vitro experimental validation. Using LC-MS/MS profiling, we identified a total of 126 chemical components. Subsequently, network pharmacological analysis screened 45 potentially active components and 129 CML-related overlapping targets. Further pathway enrichment analysis revealed that these candidate targets were predominantly involved in the PI3K/AKT and MAPK pathways. In vitro validation confirmed the suppression of PI3K/AKT phosphorylation in K562 cells. Collectively, this study provides significant insights into the active components and antitumor mechanisms of FA-2-b-β, emphasizing its potential as a promising therapeutic agent for treating CML. © 2025 Wiley‐VHCA AG, Zurich, Switzerland.

BACKGROUND: The discrimination of mucinous from serous pancreatic cysts and pseudocysts is an important clinical issue. We aimed to investigate the possibility of using our LeLISA test for distinguishing between different types of pancreatic cysts. MATERIALS AND METHODS: The LeLISA is a special type of enzyme-linked immunosorbent assay (ELISA), where a lectin (Le) replaces the catching antibody. Eight different randomly selected lectins were used for coating microwells and subsequently incubated with pancreatic cyst fluids collected via endoscopic ultrasound fine needle aspiration from patients with mucinous cysts, serous cysts, and pseudocysts, 10 patients in each group. The binding of Muc/Cp to lectins was demonstrated by the method, where cyst fluids were incubated in microwells coated with different types of lectins followed by enzyme (Horseradish peroxidase) labeled monoclonal anti-Cp. RESULTS: Muc/Cp in cyst fluids was bound to several of the 8 lectins tested, in particular to Galanthus nivalis, Agaricus blazei Murill, and Phaseolus vulgaris. This was especially noticed for fluids from mucin-pr

INTRODUCTION: Ferroptosis is a recently identified iron-dependent programmed cell death closely linked to the progression of diffuse large B-cell lymphoma (DLBCL). While studies have shown that FA-2-b-β extracted from Agaricus blazei Murill affects various malignancies, its specific role in modulating ferroptosis in DLBCL and the underlying mechanisms are not yet clear. OBJECTIVES: This study aims to elucidate the anticancer properties and mechanisms of FA-2-b-β in inducing ferroptosis in DLBCL cells. METHODS: The cell counting kit 8 assay was carried out to evaluate the inhibition of cellular proliferation. Ferroptosis was evaluated using the ferrous colorimetric method, together with kits for measuring malondialdehyde (MDA), reduced glutathione (GSH), reactive oxygen species (ROS), western blotting, JC-1 assays, and transmission electron microscopy. Reverse transcriptionquantitative polymerase chain reaction and western blot were conducted to determine whether FA- 2-b-β affected nuclear factor erythroid 2- related factor 2 (Nrf2) and heme oxygenase 1 (HO-1). RESULTS: FA-2-b-β induced ferroptosis in DLBCL cells by elevating the ROS and MDA levels, facilitating the accretion of Fe²⁺, diminishing GSH, upregulating the expression of PTGS2, and downregulating the expression of FTH1, SLC7A11, and GPX4. Furthermore, FA-2-b-β caused structural damage to mitochondria and diminished the mitochondrial membrane potential. The ferroptosis triggered by FA-2-b-β also led to the downregulation of Nrf2 and HO-1, thereby regulating the Nrf2/HO-1 pathway. CONCLUSION: FA-2-b-β suppressed DLBCL cell growth by inducing ferroptosis through the Nrf2/HO-1 pathway, making it an attractive pote

Agaricus blazei Murill polysaccharide (ABMP) has been found to exhibit significant immune regulatory effects, making them a promising candidate for complementary to the pharmacological treatment of colorectal cancer immune-related diseases. As the prevalence of colorectal cancer among younger individuals increases, the possible age-dependent anticancer modulatory effect of ABMP has not been clarified. This study evaluated the age-dependent immunoregulatory efficacy of polysaccharides extraction from A. blazei in colon tumor. Hematoxylin-eosin staining, immunohistochemistry, and vibrational spectroscopic image analysis of subcutaneous tumor tissues after ABMP preventive intervention for 14 weeks were analyzed in depth. In vivo data demonstrated that ABMP could more effectively inhibit the growth of tumor in mice at 8 compared with 12 months old without toxic side effect. Concurrently, Raman imaging spectroscopy analysis showed that ABMP preventive intervention could significantly reduce the lipid content in the tumor microenvironment (TME) of 8-month-old subcutaneous tumor-bearing mice, suggesting that the changes in lipid content in TME are closely related to anticancer activity. These results stress the importance of considering age as a factor in polysaccharide adjuvant anticancer therapy. This work highlights for the first time that age is a key determinant in the ABMP preventive effectiveness by affecting lipid levels in the TME of tumor-bearing mice, thereby exerting anticancer activity. © 2025 Wiley‐VCH GmbH.

Medicinal mushroom extracts, i.e. their dried biomass, have long been known as sources of bioactive compounds with positive effects on the human health. The antioxidant, antigenotoxic, antiviral, and immunomodulatory properties of the commercially available extracts Agaricus blazei auct. non Murrill (AB), Cordyceps sinensis (Berk.) Sacc. (CS), and Immune Assist (IA) have already been documented. This study, studied the influence of these three mushrooms on the viability of cell lines MCF-7, MDA-MB-231, and HS-5. The cytotoxicity of AB, CS, and IA at different concentrations (25, 50, 100, 200, 400 and 800 μg/mL) was evaluated using the MTT assay. The results showed that AB was the most effective and induced cytotoxicity in both cancer cell lines, with IC50 values of 96.7 μg/mL for MCF-7 and 368.4 μg/mL for MDA-MB-231. After treatment with CS and IA, the half-maximal inhibitory concentration was reached only in MDA- MB-231 cells (IC50=613 μg/mL for CS and 343.3 μg/mL for IA). We have shown here that AB, CS and IA can suppress the growth of MCF-7 and MDA-MB-231 cell lines, while affecting the survival of healthy HS-5 cells to a much lesser extent. Our in vitro results suggested that AB, CS and IA are promising natural sources with potential anticancer activity.

Agaricus blazei murill (ABM) mainly exerts its antitumor effect via modulation of the immune system. However, the immunomodulatory role of the ABM polysaccharide (ABMP) in mice with subcutaneously and intraperitoneally implanted MC38 tumor remains to be explored. This study aimed to define the progression effect of inhibiting tumor of ABMP in subcutaneous and intraperitoneal models and its effect on tumor microenvironment (TME) metabolism. In vitro experiments showed that ABMP could significantly promote the activity of CD8+ T immune cells in the co-culture system and promoted their colorectal cancer killing function (p < 0.05). In vivo animal exploration further showed that ABMP could inhibit the growth of intraperitoneal but not subcutaneous tumors. MCR-ALS analysis revealed a significant reduction in the signal of lipid-related spectral components in the TME of peritoneal tumors after ABMP intervention. In addition, preventive intervention with ABMP increased ω-3 polyunsaturated fatty acids content in intraperitoneal TME, revealing that ABMP shifted the metabolic landscape of the TME to promote T cell function and achieved immune regulation. These results suggest that the inhibitory effect of ABMP on colon cancer may be tumor stage-dependent, and that remodeling of fatty acid composition may be an important determinant of its action at any given stage.

Implant-associated infection (IAI) is a prevalent and potentially fatal complication of orthopaedic surgery. Boosting antibacterial immunity, particularly the macrophage-mediated response, presents a promising therapeutic approach for managing persistent infections. In this study, we successfully isolated and purified a homogeneous and neutral wate

IntroductionThe use of Complementary Alternative Medicine (CAM) in patients with cancer is increasing. CAM is associated with potential toxicity and drug interactions, particularly with chemotherapy. Here, we report a case of cytolysis and hepatic cholestasis in a patient who was self-medicated with a mushroom powder-based alternative therapy containing Agaricus blazei Murril (ABM) during cancer treatment.Case ReportA 43-year-old woman with metastatic colorectal cancer and hepatic metastases was admitted to our hospital for intravenous chemotherapy. Markers of hepatic grade 3 cytolysis and cholestasis were identified during the pretreatment consultation. The baseline results were within normal limits.Management and OutcomeThe chemotherapy was immediately canceled, and further tests were performed. After the investigation, the patient reported taking three mushroom powder-based capsules per day since November 2023. The dietary supplement contained ABM and Hericium erinaceus (HE) powder. After Pharmaceutical analysis, treatment with the supplement was discontinued, and the patient has not resumed. The changes in liver function were also favorable.DiscussionIn our case, given the improvement in liver function after CAM discontinuation, hepatic cytolysis appeared to be linked to ABM consumption despite the patient's liver metastases. Pharmaceutical analysis of CAM is essential to ensure the safety and optimization of cancer treatments. Patients should also communicate their CAMs to healthcare professionals and be aware of the consequences of consuming these dietary supplements. Finally, collabor

Breast cancer (BC) is the most commonly diagnosed tumor, remaining one of the leading causes of morbidity and mortality in females worldwide, with the highest rates in Western countries. Among metastatic BC (MBC), triple-negative breast cancer (TNBC) is characterized by the lack of expression of specific receptors, and differs from other subgroups of BC for its increased growth and fast spreading, with reduced treatment possibilities and a worse outcome. Actually, MBC patients are extremely prone to metastasis and consequent relapses, which affect distant target organs (e.g., brain, lung, bone and liver). Hence, the comprehension of biological mechanisms underlying the BC metastatization process is a key requirement to conceive/set up innovative medicinal strategies, with the goal to achieve long-lasting therapeutic efficacy, reducing adverse effects, and also ameliorating Quality of Life (QoL). Bioactive metabolites isolated from medicinal mushrooms (MMs) used as a supportive treatment, combined with conventional oncology, have recently gained wide interest. In fact, mounting evidence has revealed their peculiar promising immunomodulatory, anti-inflammatory and anticancer activities, even though these effects have to be further clarified. Among the group of most promising MMs are Lentinula edodes, Grifola frondosa, Ganoderma lucidum, Ophiocordyceps sinensis and Agaricus blazei, which are already employed in conventional cancer protocols in Asia and China. Recently, a growing number of studies have focused on the pharmacology and feasibility of MM-derived bioactive com

Agaricus mushrooms are an important genus in the Agaricaceae family, belonging to the order Agaricales of the class Basidiomycota. Among them, Agaricus bisporus is a common mushroom for mass consumption, which is not only nutritious but also possesses significant medicinal properties such as anticancer, antibacterial, antioxidant, and immunomodulatory properties. The rare edible mushroom, Agaricus blazei, contains unique agaricol compounds with significant anticancer activity against liver cancer. Agaricus blazei is believed to expel wind and cold, i.e., the pathogenic factors of wind and cold from the body, and is an important formula in traditional Chinese medicine. Despite its nutritional richness and outstanding medicinal value, Agaricus mushrooms have not been systematically compiled and summarized. Therefore, the present review compiles and classifies 70 natural products extracted from Agaricus mushrooms over the past six decades. These compounds exhibit diverse biological and pharmacological activities, with particular emphasis on antitumor and antioxidant properties. While A. blazei and A. bisporus are the primary producers of these compounds, studies on secondary metabolites from other Agaricus species remain limited. Further research is needed to explore and understand the anticancer and nutritional properties of Agaricus mushrooms. This review contributes to the understanding of the structure, bioactivity, and biosynthetic pathways of Agaricus compounds and provides insights for the development of functional foods using these mushrooms.

Agaricus blazei is a rare medicinal and edible fungus with a crispy taste and delicious flavor. Both fruiting body and mycelium are rich in polysaccharides, sterols, terpenoids, peptides, lipids, polyphenols, and other active ingredients, which have strong pharmacological activities such as anti-tumor, lipid-lowering, glucose-lowering, immunomodulation, optimization of intestinal flora, and anti-oxidation. Therefore, it is a kind of fungal resource with a great prospect of edible and medicinal development. Among the reported chemical components of A. blazei, blazeispirol is a series of sterol compounds unique to A. blazei, which has a spiral structure and is different from classical steroids. It is an important active ingredient found in the mycelium of A. blazei and has significant hepatoprotective activity. It can be used as a phylogenetic and chemotaxonomic marker of A. blazei strains and is considered an excellent lead compound for drug development. According to the skeleton structure characteristics, the 17 discovered blazeispirol compounds can be divided into two types: blazeispirane and problazeispirane. In order to further explore the resource of blazeispirol compounds of A. blazei, the discovery, isolation, structure, biological activity, and biosynthetic pathways of blazeispirol compounds of A. blazei were systematically reviewed. Besides, the metabolic regulation strategies related to the

ETHNOPHARMACOLOGICAL RELEVANCE: Agaricus blazei Murill (AbM) is one of the main mushrooms used for medicinal purposes. The use of AbM in the preparation of teas is widespread mainly in Asian countries, while in Brazil it is used as a functional food to combat inflammatory diseases and cancer.

Chromium (Cr), total arsenic (As), inorganic arsenic (iAs), cadmium (Cd), mercury (Hg), methylmercury (MeHg), and lead (Pb) were analyzed in in Agaricus blazei, Tricholoma matsutake, Pholiota nameko, agrocybe aegirit, Boletus edulis, Auricularia auricula, and Lentinus edodes collected from online supermarket in China from 2015 to 2017. The order of mean concentrations for the five heavy metals in edible mushrooms was As > Cd > Cr > Pb > Hg. No positive correlation was found between total As and iAs, nor between total Hg and MeHg. The contents of iAs were at a low level except for A. blazei samples. The contents of MeHg were at a low level in all test mushroom samples. And Cr, Cd, and Pb pollution were common problems in the test mushroom samples. The comprehensive factor pollution index was between 0.569 (A. auricula) and 3.056 (B. edulis). The THQ values for the five heavy metals from P. nameko, A. auricula, A. aegirit, and L. edodes samples were less than 1. The hazard index (HI) values of A. blazei, T. matsutake, and B. edulis samples for adults and children were greater than 1, indicating significant health hazard to the adults and children consumers. The cancer risk (CR) values for iAs ranged from 3.82 × 10- 6 (T. matsutake) to 8.61 × 10- 5 (A. blazei), indicating no potential carcinogenic risk to the consumers. The order for carcinogenic risk of each edible mushroom species was A

OBJECTIVE: To investigate the mechanism of drug reversing resistance of Agaricus blazei extract FA-2-b-β on T cell acute lymphoblastic leukemia (T-ALL) cell lines. METHODS: Cell proliferation was detected by CCK-8 assay; the apoptosis, cell cycle mitochondrial membrane potential, and intracellular rhodamine accumulation were detected by flow cytometry, and apoptosis-related gene and protein expression were detected by qPCR and Western blot; the membrane surface protein MDR1 was observed by immunofluorescence microscopy. RESULTS: Different concentrations of FA-2-b-β significantly inhibited proliferation and induced apoptosis of CCRF-CEM and CEM/C1 (P<0.05), and CCRF-CEM cell cycle were arrested at S phase, and CEM/C1 cells were arrested at G0/G1 phase. Western blot and qPCR results show that FA-2-b-β inhibited ABCB1、ABCG2、CTNNB、MYC and BCL-2 expression, but upregulated Bax expression. In addition, FA-2-b-β reversed the resistance characteristics of CEM/C1 drug-resistance cells, which decreased mitochondrial membrane potential, and significantly increased the intracellular rhodamine accumulation, and weakening of the expression of the membrane surface protein MDR1. With the Wnt/β-catenin inhibitor (ICG001), the process was further intensified. CONCLUSION: Agaricus Blazei Extract FA-2-b-β inhibits cell proliferation, promotes apoptosis, regulate

Agaricus blazei Murrill or Himematsutake is an edible and medicinal mushroom. Agaricus blazei Murrill's fruiting body extracts have anticancer properties, although the mechanism is unknown. Basic or organic solvents, which are hazardous for human health, are generally used to prepare Agaricus blazei Murrill's extracts. The inhibition of immune checkpoint molecules and Axl receptor is an effective therapy in cancer. This study assessed whether subcritical water extracts of the Agaricus blazei Murrill's fruiting body or mycelium affect the expression of Axl and immune checkpoint molecules in lung cancer cells. We used A549 cells and mouse bone marrow-derived dendritic cells in the experiments. We prepared subcritical water extracts from the Agaricus blazei Murrill's fruiting body or mycelium. The subcritical water extracts from the Agaricus blazei Murrill's fruiting body or mycelium significantly inhibited the expression of immune checkpoint molecules and Axl compared to saline-treated cells. Additionally, the hot water extract, subcritical water extract, and the hot water extraction residue subcritical water extract from the Agaricus blazei Murrill's mycelium significantly enhanced the expression of maturation markers in dendritic cells. These observations suggest that the subcritical water extract from Agaricus blazei Murrill's mycelium is a promising therapeutic tool for stimulating the immune response in cancer.

Edible mushrooms have been increasingly introduced into the human diet, which has driven research into their functional properties. Thus, Agaricus brasiliensis Murill or Agaricus blazei Murill (ABM) is a species native to the Brazilian biome, whose fruiting body has been used not only for dietary purposes, but also in the development of functional foods or as source of molecules of pharmacological interest. The bioactivity of ABM has been related to the presence of polysaccharides, although the contribution of other metabolites cannot be discharged. This work describes the polysaccharides isolation methodology and preparation of the extracts of ABM and their biological activities. Furthermore, it presents a general outline of its characterizations regarding composition, chemical structure and properties in solution. The ABM and its chemical constituents exh

Medicinal mushrooms are widely used in East Asia for the treatment of various diseases, especially in complementary cancer care. While there is a growing interest in medicinal mushrooms in Western countries and an increasing number of pre-clinical studies indicate distinct anti-cancer and regenerative properties, little is known about their potential relevance for clinical practice. This review aims to provide an overview of the clinical evidence, significance and potential role of medicinal mushrooms in complementary cancer care. Scientific databases for (randomized) controlled clinical trials evaluating whole spectrum formulations of medicinal mushrooms (mushroom powder and mushroom extracts) in cancer patients during and/or after conventional oncological treatment were searched. Eight studies met our inclusion criteria (eight randomized controlled trials, one controlled clinical trial). The medicinal mushrooms investigated were Agaricus sylvaticus (two trials), Agaricus blazei murill (two trials), Antrodia cinnamomea (one trial), Coriolus versicolor (one trial) and Ganoderma lucidum (three trials); all were compared to placebo and administered orally. A variety of cancer entities, outcomes and treatment durations were observed. Study results suggested beneficial effects of medicinal mushrooms, particularly quality of life and reduction of adverse effects of conv

OBJECTIVE: To investigated the anti-tumor in vivo effect and mechanism of the acid RNA protein complex (FA-2-b-β) of Agaricus blazei Murrill extract. METHODS: CCK-8 method was used to detected the inhibitory effect of FA-2-b-β on proliferation of primary CML cells from newly diagnosed CML patients, the CML mouse model was established by trail-venous injection of primary CML cells, and the survival time, blood cell count and body weight were observed, the immunoflouresence and immunehistochemistry analysis, RT-qPCR, Western bolt were used to detemine the expression of caspase-3 signal pathway-related apoptosis genes and proteins. RESULTS: The experiments in vitro showed that the proliferative inhibitory rate in drug-treated group increased with concentration- and tim

Some varieties of edible mushrooms can accumulate high contents of arsenic, which is a public health concern. In this study, we developed a high-performance liquid chromatography method linked to inductively coupled plasma triple quadrupole mass spectrometry (HPLC-ICP-MS/MS) for sensitive and accurate determination of arsenite, arsenate, monomethylarsonic acid, dimethylarsinic acid, arsenocholine and arsenobetaine in edible mushrooms. The six arsenic species were extracted ultrasonically from mushrooms using ultrapure water at 60 °C as the solvent, separated on a PRP-X100 anion exchange column (4.1 × 250 mm, 10 µm), with 20 mmol/L NH4HCO3 and 50 mmol/L (NH4)2CO3 as the mobile phase, and quantified using ICP-MS/MS in the oxygen reaction mode. The linear range of the method was 0.5 µg/L-100 µg/L with detection and quantification limits

Although medicinal mushroom extracts have been proposed as promising anti-cancer agents, their precise impacts on metastatic breast cancer are still to be clarified. For this purpose, the present study exploited the effect of a novel medicinal mushroom blend, namely Micotherapy U-care, in a 4T1 triple-negative mouse breast cancer model. Mice were orally administered with Micotherapy U-care, consisting of a mixture of Agaricus blazei, Ophiocordyceps sinensis, Ganoderma lucidum, Grifola frondosa, and Lentinula edodes. The syngeneic tumor-bearing mice were generated by injecting 4T1 cells in both supplemented and non-supplemented mice. After sacrifice 25 days later, specific endpoints and pathological outcomes of the murine pulmonary tissue were eva

Since the 1980s, medicinal effects have been documented in scientific studies with the related Basidiomycota mushrooms Agaricus blazei Murill (AbM), Hericium erinaceus (HE) and Grifola frondosa (GF) from Brazilian and Eastern traditional medicine. Special focus has been on their antitumor effects, but the mushrooms' anti-inflammatory and antiallergic properties have also been investigated. The antitumor mechanisms were either direct tumor attack, e.g., apoptosis and metastatic suppression, or indirect defense, e.g., inhibited tumor neovascularization and T helper cell (Th) 1 immune response. The anti-inflammatory mechanisms were a reduction in proinflammatory cytokines, oxidative stress and changed gut microbiota, and the antiallergic mechanism was amelioration of a skewed Th1/Th2 balance. Since a predominant Th2 milieu is also found in cancer, which quite often is caused by a local chronic inflammation, the three conditions-tumor, inflammation and allergy-seem
