Figure 1. SN up-regulated ATF6 and down-regulated CHOP and PERK in OGD-injured PC12 cells: (A) immunoblotting images of expression of p-PERK, PERK, ATF6, CHOP and β-actin proteins under different experimental conditions; (B), (C), and (D), respectively, quantitative densitometric analysis of the p-PERK, ATF6 and CHOP protein bands. Data are shown as means ± SEM (n=3): ***p<0.001 vs. NC; ###p<0.01 vs. OGD [NC: normal control; OGD: oxygen and glucose deprivation (4 h); OGD-SN: oxygen and glucose deprivation (4 h) co-treated with SN (100 µm); SN: sodium nitrite (100 µm) treated].
