Fig. 7: Profiling hippocampal protein expression associated with 40 Hz light treatment.

a GO analysis according to the functions of 31 proteins, which significantly altered their expression in the 2VO + LED group. b Representative western blots are showing increased levels of RGS12 expression 3 d (4 repeats from n = 2 mice) and 7 d (6 repeats from n = 3 mice) post 2VO. c, d Quantifications of RGS12 expression using β-actin as an internal standard of 3 d (n = 2 mice in each group) and 7 d (n = 3 mice in each group) post 2VO groups, respectively. Data represent the mean ± SEM. Error bars indicate SEM. * is for comparison between Sham and 2VO groups; # is for comparison between 2VO and 2VO + LED groups. *,#P < 0.05. The test used in d 2ANOVA with LSD’s post hoc test. Source data are provided as a Source Data file.
