Turkey Tail Mushroom - Trametes versicolor
The turkey tail mushroom or cloud mushroom, Trametes versicolor has been studied and been shown to have anti-tumor property against many types of cancers. Ethanolic extracts of Yunzhi, a proprietary dietary supplement prepared from extracts of T. versicolor reduces the growth of hormone responsive prostate cancer LNCaP cell growth. The polysaccharo-peptide in the extract raises the possibility that Yunzhi may be considered as an adjuvant therapy in the treatment of hormone responsive prostate cancer; additionally, it may have chemo preventive potential to restrict prostate tumorigenic progression from the hormone-dependent to the hormone-refractory state.1 The growth of several human cancer cell lines, viz., gastric cancer (7907), lung cancer (SPC), leukemia (MCL), and lymphoma (SLY)-was markedly inhibited by a crude C. versicolor extract at 1 mg/mL after 72 h of incubation. 2 The polysaccharide peptide krestin of T. versicolor has potential to be used as an adjuvant in breast cancer prevention.3 The polysaccharide of this mushroom has been demonstrated to inhibit the proliferation of cancer cells in vitro and in vivo, examined on the human hepatoma cancer (QGY) cell lines. These results showed that the polysaccharide inhibited the proliferation in low concentrations (20 mg/L) and the IC50 value was 4.25 mg/L. Apoptosis and significant decrease in the expression of the cell cycle-related genes (p53, Bcl-2, and Fas,) in these cells following treatment, indicate that the polysaccharide can be a potential candidate in cancer therapy. 4
