Ophiopogonin B (OP-B) induces the autophagy and apoptosis of colon cancer cells by activating JNK/c-Jun signaling pathway. Ophiopogonin B is a saponin compound isolated from Radix Ophiopogonjaponicus [1].
In Vitro, Ophiopogonin B (0, 5, 10 and 20 μM) suppresses the proliferation of HT-29 and HCT-116 cell lines through the G0/G1 phase cell cycle arrest[1]. Ophiopogonin B induces apoptosis by inhibiting the expression of Bax and cleaved caspase 3 and promoting the expression of Bcl-2. Treatment with Ophiopogonin B also increases the expression of Beclin 1 and the conversion of LC3I to LC3II with the activation of JNK/c-Jun signaling pathway[1].
