The maturation of dendritic cells into more immunostimulatory dendritic cells by stimulation with different combinations of immunologic agents is expected to provide efficient, adoptive immunotherapy against cancer. Soluble b-glucan maitake D-fraction, extracted from the maitake mushroom Grifola frondosa, acts as a potent immunotherapeutic agent, eliciting innate and adoptive immune responses, thereby contributing to its antitumor activity.

A variety of nutritional supplements are commercially available for the potential therapeutic purpose for dogs and other domestic animals with cancers. However, the efficacy of these supplements on those cancer-bearing animals has not been verified and remains uncertain, due to the lack of the sufficient scientific studies/data. To address this important issue, we examined actual anticancer effects of five selected commercial products on the two types of canine cancer models in vitro. Among them, PET-Fraction (PET-F) obtained from maitake mushroom has been shown to...

Maitake mushroom (Grifola frondosa) is an edible, medicinal mushroom.  It has been extensively studied for the past 30 years, revealing numberous medicinal properties that could provide great health benefits.  Those include various physiological benefits ranging from immunomodulatory and antitumor activities to treatment for diabetes, hypertension, hypercholesterolemia, viral infections (hepatitis B and human immunodeficiency virus), called “maitake D-fraction” and “maitake SX-fraction”.  A number of scientific studies have been performed on...

Chemotherapy is currently one of the most common therapeutic options for cancer patients despite the poor efficacy with considerable side effects. We then examined if D-fraction (DF), a bioactive mushroom extract, could potentiate (poor) anticancer effects of those drugs in vitro. Three urologic cancers, prostate, bladder, and kidney cancers, were tested with various chemotherapeutic drugs and their combinations with DF. Compared to individual drugs alone, combinations of drugs and DF have improved anticancer activity, resulting in the significant (P < 0.05) cell...

Immediate Release                      ~ A New Gene Study Suggests Strong Clinical Implications ~   January 20, 2014-  A research group of National Scientific and Technical Research Council in Argentina (CONICET) headed by Dr. Gabriela Balogh has announced that they have successfully identified genes that would be responsible for the tumor supression in human breast cancer cells (MCF-7) by a mushroom extract called Maitake D-Fraction. The results include that D-Fraction may even revert the malignancy of cancer cells by the modification of related...

Grifola frondosa, also known as maitake, is a culinary mushroom with immune-enhancing and antitumor effects. Numerous studies have investigated the activity of maitake polysaccharide extracts, but studies of maitake proteins are scarce. In this study, we purified and characterized a new G. frondosa protein, GFP, from maitake fruiting bodies. GFP is a nonglucan heterodimeric 83 kDa protein that consists of two 41 kDa subunits. GFP induced interferon-γ secretion by murine splenocytes and natural killer cells and activated the maturation of bone marrow-derived dendritic...
