(A) Representative western blot bands of KISS1, 4HNE, HO1,Bcl2, and BAX; (B) Densitometric quantification of KISS1, 4HNE, HO1, Bcl2, and BAX at 24 h after SAH; (C) KISS1 siRNA knockdown significantly aggravated the neurological deficits, resulting in the lower modified Garcia score and beam balance score in SAH rats than SAH alone or scramble siRNA-treated SAH; (D, E) Representative western blot bands and densitometric quantification of KISS1 demonstrated the knockdown efficacy of KISS1 siRNA on brain KISS protein levels in naïve and SAH rats, *P < 0.05, **P < 0.01. Data was represented as mean ± SD. n = 4–10/group. One-way ANOVA, Tukey’s post hoc test.
