Abstract Morchella angusticeps Peck, one of the most popular edible mushrooms, has attracted great attention due to its delicious taste and healthy properties. However, both its biological effects and the possible mechanism of action have not yet been known. We investigated the anti-proliferative activity of the phenolic extract derived from Morchella angusticeps Peck (MPE) against HepG2 human hepatocellular carcinoma cells. Results showed that MPE at non-cytotoxicity doses significantly inhibited the proliferation of HepG2 cells in a dose-dependent manner with inhibitory rates ranging from 18 to 90% (P<0.01). The possible mechanism might be that MPE induced apoptosis through initiating the mitochondrial death pathway by regulating Bax, Bcl-2 and cleaved caspase-3. On the other hand, MPE might trigger cell cycle arrest at G0 /G1 /S phases by managing p21, Cyclin D1, cyclin-dependent kinases-4 (CDK4) and proliferating cell nuclear antigen (PCNA). Additionally, MPE downregulated TRAF-2 and p-p53, while upregulated p-ASK1 and p-p38. Therefore, it could be inferred that MPE might induce the anti-proliferative function to HepG2 cells through the p38/MAPK signal transduction pathway.
