- Abstract: OBJECTIVE: To explore the effect of amarogentin on the induction of liver cancer cell line Huh-7 apoptosis and the regulation of PKA/C. METHODS: Liver cancer cell line Huh-7 were divided into 4 groups, control, amarogentin, amarogentin+H89 and amarogentin+H7 group (n=8). The cells were treated with amarogentin (30 mmolL-1) for 6 h besides control group. The amarogentin+H89 and amarogentin+H7 group cells were treated with corresponding compounds at the last 3 h (H89 at 10 mmolL-1 and H7 10 mmolL-1). The apoptotic proteins and MEK/ERK signaling pathway related proteins were detected by Western blotting. The Caspase 3 and Caspase 9 were also be assayed by immune-cytochemistry. At the meaning time, the apoptosis state was assayed by DAPI. RESULTS: The results showed that the Bax, Caspase 3 and Caspase 9 were increased (P>0.05) while the Bcl2 were decreased (P>0.05) expressed greatly after the medication of amarogentin when compared with control. At the same time, the expression of Ras, Rsf, MEK and ERK1/2 were increased (P>0.05) greatly after the medication of amarogentin when compared with control. Those abnormalities were normalized greatly by the medication of H89 (P>0.05) but not H7(P>0.05). CONCLUSION: Amarogentin could promote the apoptosis of liver cancer cell line Huh-7 which is mediated by PKA.
