The AMPK-ACC signaling contributes to CPI-613-induced apoptosis in pancreatic cancer cells. a, b, e The effects of AMPK inhibitor Compound C on CPI-613-induced apoptosis. AsPC-1 and PANC-1 cells were treated 10 μM Compound C for 1 h, followed by treated with 200 μM CPI-613 for 48 h. Apoptosis was determined by flow cytometry with Annexin V-FITC/PI staining (a, b) and western blot with antibodies against PARP and p-ACC (e). c, d, f The effects of ACC inhibitor TOFA on CPI-613-induced apoptosis. AsPC-1 and PANC-1 cells were treated with 10 μM TOFA for 1 h, followed by treated with 200 μM CPI-613 for 48 h. Apoptosis was determined by flow cytometry with Annexin V-FITC/PI staining (c, d) and Western blot with antibodies against PARP and p-ACC (f). The representative results of flow cytometry and quantitative data from three independent experiments were shown in (a, c) and (b, d), respectively.
