A novel bioactive polysaccharide, GFP-22, was isolated from the fruit bodies of Grifola frondosa by anion-exchange and gel filtration chromatography. Structure of GFP-22 was investigated using gas chromatography–mass spectrometry (GC–MS), methylation, nuclear magnetic resonance (NMR), high-performance size exclusion chromatography-multi-angle laser light scattering-refractive index detector (HPSEC-MALLS-RI) and atomic force microscopy (AFM) analysis. The backbone of GFP-22 is composed of 1,4-β-D-Glcp, 1,3-β-D-Glcp, 1,6-α-D-Glcp, 1,6-α-D-Galp, 1,4,6-α-D-Manp...

Triple-negative breast cancer (TNBC) is associated with poor prognosis, high local recurrence rate and high rate of metastasis compared with other breast cancer subtypes. In addition, TNBC lacks a targeted therapy. This scenario highlights the need for novel compounds with high potential for TNBC treatment. In this regard, natural products are important sources of anticancer drugs. D-Fraction, a proteoglucan extracted from the edible and medicinal mushroom Grifola frondosa (Maitake), is a dietary supplement that has been shown to exert both immunostimulatory...

Grifola frondosa, a type of food and medical fungus, has been shown to exhibit various pharmacological activities, including anticancer effects. As the most typical cancer diagnosed among female patients, breast cancer remains a huge concern threatening human health globally. In the present study, the anti-breast cancer effects of Grifola frondosa polysaccharides (GFPs) and the underlying mechanisms were investigated in MCF-7 and MDA-MB-231 cells, as well as in nude mice bearing MCF-7 tumor xenografts. GFPs exerted cytotoxic effects on the cells, as indicated by a decrease...

D-Fraction is protein-bound b-1,6 and b-1,3 glucans (proteoglucan) extracted from the edible and medicinal mushroom Grifola frondosa (Maitake). The antitumoral effect of D-Fraction has long been exclusively attributed to their immunostimulatory capacity. However, in recent years increasing evidence showed that D-Fraction directly affects the viability of canine and human tumor cells, independent of the immune system. Previously, we have reported that D-Fraction modulates the expression of genes associated with cell proliferation, cell death, migration, invasion, and...

Grifola frondosa is a widely consumed edible and medicinal fungus, Ancient books record that it can boost qi and fortify the spleen, moisten the lung and protect the liver. Modern people mainly use it to assist in the treatment of diabetes mellitus and various cancers. Over the past three decades, G. frondosa polysaccharides were shown to possess various promising bioactivities, mainly including anti-tumor and immunomodulation, anti-oxidation, anti-hyperglycemia, and meanwhile can effectively act on the skin and hematopoietic stem cells. The purpose of the present review...

ABSTRACT: Mushroom extracts have shown promising effects in the treatment of cancer and various chronic diseases. Osteoporosis is considered one of the most widespread chronic diseases, for which currently available therapies show mixed results. In this research we investigated the in vitro effects of water extracts of the culinary-medicinal mushrooms Trametes versicolor, Grifola frondosa, Lentinus edodes, and Pleurotus ostreatus on a MC3T3-E1 mouse osteoblast-like cell line, primary rat osteoblasts, and primary rat osteoclasts. In an animal osteoporosis model,...
