Fig. 1From: NGF receptors and PI3K/AKT pathway involved in glucose fluctuation-induced damage to neurons and α-lipoic acid treatmenta Effect of glucose on PC12 cell viability. b Effects of ALA on PC12 cell viability under normal glucose concentration. c Effects of ALA on PC12 cell viability under glucose fluctuation. Results are presented as the mean ± SD (n = 3). ***P < 0.001, **P < 0.01,*P < 0.05, compared to the (a) control or (b, c) ALA (0 µmol/L) group. ###P < 0.001, ##P < 0.01, #P < 0.05 versus the ALA (100 µmol/L) groupBack to article page
