A: Neurons were subjected to 3, 6 and 9 h of OGD followed by 6 h of reoxygenation which lead to >2 fold increase in LDH assay. C21 did not affect LDH release into the supernatant. N=3. *P<0.05 vs Normoxic control.
B: C21 in 100 and 1000 nM concentrations decreased cleaved caspase 3 as measured by western blotting in cell lysate. N=3. *P<0.05 vs respective 100, 1000 nM groups and normoxic control. #P<0.05 vs respective 100, 1000 nM groups and normoxic control.
C: C21 anti-apoptotic effect is mediated through AT2R stimulation. C21 anti-apoptotic effect was blocked by PD123319 but not anti-IL-10 neutralizing antibody. N=3. *P<0.05 vs normoxic control, 100 nM, 100 nM, and 100nM+IL-10_Ab.
