Figure 9. DHCR7 knockdown influenced mitochondrial function of MDA-MB-231 cells. (A, B) MDA-MB-231 cells were treated with DHCR7 siRNA. ROS production was detected by fluorescence microscope and flow cytometer. (C, D) The level of MMP was detected by JC-1 staining using a fluorescence microscope and flow cytometer. *p < 0.05; **p < 0.01.
