Bcl-2 overexpression inhibits the induction of ER-mitochondrial interactions by cisplatin in SKOV3 cells. (A) Colocalization of IP3R and VDAC1 in pc-SKOV3 and Bcl-2-SKOV3 cells after cisplatin treatment (bar, 10 µm). (B and C) Representative transmission electron microscopic photomicrographs of pc-SKOV3 and Bcl-2-SKOV3 cells treated with cisplatin for 24 h (scale bar, 200 nm). White arrowheads indicate ER-mitochondrial contacts. Results are the mean ± SD of three independent experiments. *P<0.05. ER, endoplasmic reticulum.
