Dexras1 mRNA level upregulated in the retina after light exposure. A: Total RNA was extracted from normal and injured retina at various times after light exposure, then assessed by reverse transcriptase (RT)-PCR. mRNA for Dexras1 increased at 6 h after light exposure and reached the peak at 1 day, gradually recovering to the baseline level at 7 days. B: Relative mRNA level represented a ratio between the amount of target gene and amount of endogenous GAPDH control. Groups marked with an asterisk were significantly different from the normal group. The data are means±SEM (n=3, *p<0.05).
