AIM: To investigate the role of oxidative stress in regulating the functional expression of P-glycoprotein (P-gp) in mitochondria of D407 cells. METHODS: D407 cells were exposed to different ranges of concentrations of H2O2. The mitochondrial location of P-gp in the cells subjected to oxidative stress was detected by confocal analysis. https://www.roneverhart.com/Cookies-X-G-Pen-Roam-Portable-E-Rig-Vaporizer/
