Ganoderic acid DM (GADM) is a triterpenoid isolated from Ganoderma lucidum, a well-known edible medicinal mushroom, it effectively inhibits cell proliferation and colony formation in MCF-7 human breast cancer cells, which is much stronger than that of MDA-MB-231 breast cancer cells. [1]
Ganoderic Acid DM is an antiandrogenic osteoclastogenesis inhibitor.[2]
Ganoderic acid DM especially suppresses the expression of c-Fos and nuclear factor of activated T cells c1 (NFATc1), this suppression leads to the inhibition of dendritic cell-specific transmembrane protein (DC-STAMP) expression and reduces osteoclast fusion.[3]
Ganoderic acid DM (GA-DM) has shown toxicity to both androgen-dependent and independent prostate cancer cells with reduced osteoclastogenesis in late stage metastatic disease, it may an alternative agent for the treatment of advanced prostate cancer.[4]
