Study finds that maitake mushroom extract, MD-Fraction (a beta-glucan), has significant anti-tumor activity and anti-metastasis activity through NK activity, Antigen presenting cells, and through suppression of ICAM-1.
Good review of data on vitamin D, Vitamin D receptors and cancer risk. Studies have shown that low Vitamin D levels are associated with increased cancer risk and that higher vitamin D levels are associated with reduced cancer risk. The ability to fully map out vitamin Ds role in the physiology is probably difficult due to the heterogeneity of cancer development and physiology.
