High Glucose-Induced Oxidative Stress Mediates Apoptosis and Extracellular Matrix Metabolic Imbalances Possibly via p38 MAPK Activation in Rat Nucleus Pulposus Cells

Figure 3

Representative Western blot and histogram showing p38 MAPK activation in nucleus pulposus cells treated with high glucose (HG, 25 mM) in the absence or presence of N-acetylcysteine (NAC) or SB 202190 (SB). Values are expressed as means ± SEM. versus control; versus HG group.
