Effects of Notch1 siRNA on the expression of molecules in the Notch1 pathway at 24 h post-SAH. The qRT-PCR analysis of the efficiency of siRNA-mediated knockdown of Notch1 in ipsilateral cerebral cortex (a); n = 3 in each group; data are expressed as the mean ± SEM **P < 0.01 versus Sham, ##P < 0.01 versus SAH + Scramble siRNA group. The protein levels of Notch1 pathway-related agents were assessed by Western blot (b) and quantification of Notch1 (c), NICD (d), RBP-Jκ (e), and Hes-1 (f) at 24 h post-SAH; n = 6 in each group; data are expressed as the mean ± SEM. *P < 0.05 versus Sham, #P < 0.05, ##P < 0.01 versus SAH + Scramble siRNA group. Representative images of NICD- and Iba1-positive cells (g) and immunohistochemistry staining for RBP-Jκ and Hes-1 (h) showing that Notch1 siRNA reduced the levels of NICD, RBP-Jκ and Hes-1 in ipsilateral cerebral cortex. Scale bar = 50 μm
