Upon administration, ursolic acid may promote apoptosis and inhibit cancer cell proliferation through multiple mechanisms. This may include the regulation of mitochondrial function through various pathways including the ROCK/PTEN and p53 pathways, the suppression of the nuclear factor-kappa B (NF-kB) pathways, and the increase in caspase-3, caspase-8 and caspase-9 activities."}]
