From: DA-JC1 improves learning and memory by antagonizing Aβ31–35-induced circadian rhythm disorder
The effect of DA-JC1 on Aβ31–35-induced abnormal expression of Per2 in HT22 hippocampal cells. (a) mRNA levels of Per2 were assayed at indicated circadian times. (b) Representative immunoblots show the levels of Per2 at CT16. Quantifications of Western blots were obtained by using β-actin as a loading control. (c) mRNA expression of Per2 in the hippocampal tissue at different time points was detected. Data are expressed as means ± SEM (n = 6 per group). *P < 0.05 compared with the control group; #P < 0.05 compared with the Aβ31–35 group
