Effect of uncoupling protein 2 (UCP2) overexpression on per meability transition pore (PTP) opening and cytochrome c release. (A) Overexpression of UCP2 in human umbilical vein endothelial cells (HUVECs) significantly delayed the time of mPTP opening compared to the adenovirus β-galactosidase (Ad-β-gal) control. (B) Western blot analysis of the release of cytochrome c from mitochondria into the cytosol. The values are presented as the means ± SD of three independent experiments. *P<0.01 vs. control.
