Ganoderic acid H( GA-H )and ganoderic acid A(GA-A ) suppress growth (cell proliferation and colony formation) and invasive behavior (adhesion, migration and invasion) of MDA-MB-231 cells; they mediate their biological effects through the inhibition of transcription factors AP-1 and NF-kappaB, resulting in the down-regulation of expression of Cdk4 and the suppression of secretion of uPA, respectively; furthermore, the activity of ganoderic acids is linked to the hydroxylation in the position 7 and 15 (GA-A) and 3 (GA-H) in their triterpene lanostane structure; so hydroxylated triterpenes from G. lucidum could be promising natural agents for the therapy of invasive breast cancers.[1]
