Fig. 3: STK25 regulates oxidative stress in human aortic endothelial and smooth muscle cells.

hASMCs and hAECs were transfected with STK25 siRNA or NTC siRNA. a–c Representative images of cells stained with DHE (pink) or processed for immunofluorescence with anti-8-oxoG (red) or anti-E06 (red) antibodies; nuclei stained with DAPI (blue). Quantification of the staining. d, f Cellular ROS content. e, g Cellular NO content. In (a–c), the scale bars represent 100 µm. Data in (a–c) are mean ± SEM from 6-8 wells per group; data in (d–g) are mean ± SEM from 20 wells per group. OA, oleic acid. *P < 0.05, **P < 0.01, ***P < 0.001 for STK25 siRNA vs. NTC siRNA.
