(B) Panel i: HeLa cells were treated with control siRNA or Bim siRNA. After 48 hr, one set of transfections were starved in HBSS for 2 hr. Blots were probed as indicated. LC3-II/tubulin ratio of siRNA-transfected cells is set as 1 (n = 3). Data are shown as mean ± SD. ∗∗∗p < 0.001; NS, not significant. Panel ii: HeLa cells were treated with control siRNA or Bim siRNA. After 48 hr, one set of transfections were treated with Baf for 2 hr; one set of transfections were starved and treated with Baf for 2 hr. Blots were probed as indicated and analyzed as in (Bi). ∗∗p < 0.01; NS, not significant.
