PGC-1α alleviates mitochondrial dysfunction via TFEB-mediated autophagy in cisplatin-induced acute kidney injury


Figure 2. PGC-1α alleviates cisplatin-induced injury in HK2 cells. HK2 cells were exposed to cisplatin (2.5 μM, 5 μM, 10 μM) for 48h. (A) Cell viability was determined by CCK8 assay. (B) Cisplatin-induced cell apoptosis were determined by flow cytometry. (C) The expression of apoptosis-related proteins (Bax and Bcl-2) and PGC-1α was measured by western blotting. (D) Over-PGC-1α attenuated cell apoptosis in cisplatin-treated (5 μM) HK2 cells (overcon, black column; overpgc-1α, white column). The expression of PGC-1α and Bcl-2 and Bax was analyzed by western blotting. (E) Apoptosis was determined by flow cytometry. Data are provided as the mean ± SEM, n=3 independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001 vs. Con; &P < 0.05, &&P < 0.01 vs. Cisp. (overcon, overcontrol; Cisp, cisplatin).
