Inhibition of Mer reduced STAT1 activation and SOCS expression following TBI. a, b, c, e Representative immunoblots and quantification showing the expression of phosphorylated Mer (p-Mer) (a), phosphorylated STAT1 (p-STAT1) (b), SOCS-1 (c), and SOCS-3 (e) was significantly inhibited by Mer siRNA administration on day 3 following TBI. TBI + vehicle: TBI + V, TBI + control siRNA: TBI + C; TBI + Mer siRNA: TBI + M. GAPDH: loading control. Data are expressed as fold change compared to the TBI + V group; n = 6 mice per group. d, f Quantitative RT-PCR analysis showing Mer siRNA application significantly inhibited the mRNA expression of SOCS-1 (d) and SOCS-3 (f) in the injured cortex at 3 days post-TBI. Data are expressed as fold change compared to the TBI + V group; n = 6 mice per group. In a–f, data are presented as Mean ± SD; ns, nonsignificant, p > 0.05; *** p < 0.001. One-way ANOVA followed by Bonferroni’s post hoc tests
