Oleanolic acid (Caryophyllin) is a natural compound fromplantswith anti-tumor activities.

Oleanolic acid (OA) suppresses the proliferation of lung cancer cells in both dose- and time-dependent manners, along with an increase in miR-122 abundance. CCNG1 and MEF2D, two putative miR-122 targets, are found to be downregulated by OA treatment^[1]. OA induces autophagy in normal tissue-derived cells without cytotoxicity. OA-induced autophagy is shown to decrease the proliferation of KRAS-transformed normal cells and to impair their invasion and anchorage-independent growth^[2].

Mouse model experiments also demonstrat that OA suppresses the growth of KRAS-transformed breast epithelial cell MCF10A-derived tumor xenograft by inducing autophagy^[2]. Activation of MAPK pathways, including p-38 MAPK, JNK and ERK, is triggered by OA in both a dose and time-dependent fashion in all the tested cancer cells. OA induces p38 MAPK activation promoted mitochondrial translocation of Bax and Bim, and inhibits Bcl-2 function by enhancing their phosphorylation. OA can induce reactive oxygen species (ROS)-dependent ASK1 activation, and this event is indispensable for p38 MAPK-dependent apoptosis in cancer cells^[3].It is also proved that p38 MAPK knockdown A549 tumors are resistant to the growth-inhibitory effect of OA^[3]. In OA-treated EAM mice the number of Treg cells and the production of IL-10 and IL-35 are markedly increased, while proinflammatory and profibrotic cytokines are significantly reduced^[4].
