(E) Protein expression of Jag2, NOX2, proliferating cell nuclear antigen (PCNA), and survivin in different groups was detected by the western blot. (F) Cell migration levels were assessed using a Transwell assay. (G) Protein expression of nuclear factor erythroid 2–related factor 2 (Nrf2) and SOD2 in different groups detected by the western blot; levels of superoxide dismutase (SOD), malondialdehyde (MDA), total glutathione (GSH), reduced GSH, and oxidized GSH measured by assay kits; reactive oxygen species (ROS) levels assessed by 2',7'‐dichlorodihydrofluorescein diacetate (DCFH‐DA) staining. (H) Protein expression of caspase‐3, cleaved caspase‐3, B‐cell lymphoma 2 (Bcl2), and Bcl‐2‐associated X protein (BAX) in different groups detected by the western blot. (I) Apoptosis levels in cells of different groups were assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, scale bar = 50 μm. (J) Apoptosis levels in cells of different groups were measured by flow cytometry (FCM). * indicates p < 0.05 compared to the hypoxia + siJag2 group, ** indicates p < 0.01 compared to the hypoxia + siJag2 group; all cell experiments were performed in triplicate.

Article Snippet: After PASMCs infected with the corresponding siRNA were treated under normoxic or hypoxic conditions, the cells were incubated with the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay kit (HY‐K1079, MCE) for 1 h in a dark environment.
