From: Blue light induces a neuroprotective gene expression program in Drosophila photoreceptors
An intact phototransduction pathway and calcium influx are required for blue light-induced upregulation of stress response genes, but not downregulation of visual function genes. Six-day-old male w1118, ninaE7 and trp9 flies were exposed to 3 h blue light or dark control, and gene expression was analyzed in dissected eyes at 0 or 3 h following treatment by qPCR. Expression is shown relative to the geometric mean of RpL32 and eIF1A and is normalized to the dark control for each genotype, which is set to one. p values, t test between ninaE7 or trp9 and w1118 at the same time post-treatment (*p < 0.05; **p < 0.01, ***p < 0.001; n = 3)
