RT-PCR analysis revealed elevated expression of (A) Bdnf (Two way ANOVA, F(1,71) = 7.064; p = 0.01), (B) Fgf2 (Two way ANOVA, F(1,65) = 4.956; p = 0.03), (C) Casp3 (Two way ANOVA, F(1,69) = 5.223; p = 0.026), and (D) Gs (Two way ANOVA, F(1,66) = 5.197; p = 0.03) in P23H-1 rats (aged 4 weeks) subjected to one 30-min session of WES and sacrificed 1 h after treatment compared to Sham eyes. No significant differences in gene expression were detected in retinas harvested 24 h after WES therapy. Asterisks indicate post-hoc comparisons: *p < 0.05, **p < 0.01.
