Effect of GSK2606414 on ROS and mitochondrial function. Representative images and corresponding bar graphs of (a) DCFDA staining (b) Mitosox staining. Photographs were taken at 200× magnification (scale: 100 μM). Values are expressed as mean ± SEM (n = 3). NC: normal N2A cells, GSK 1: normal N2A cells treated with GSK260414 (1 μM), HG: hyperglycemic N2A cells (30 mM β-D glucose), HG+ GSK 0.5: HG cells treated with GSK260414 (0.5 μM), HG+ GSK1: HG cells treated with GSK260414 (1 μM), ^^P < 0.01, ^^^P < 0.001 v/s NC and ∗∗P < 0.01, ∗∗∗P < 0.001 v/s HG.
