Figure Lengend Snippet: Majoon Ushba abrogated the JAK-2-STAT-3 signaling axis in an IMQ-induced psoriasis mice model. Skin tissue from mice in the respective experimental groups was obtained following euthanasia and used to isolate total protein and RNA. (A) Relative protein levels of JAK-2, p-JAK2, STAT-3, and p-STAT3 were assessed using western blotting. (B) Additionally, the protein levels of Ki67, a cell proliferation marker, and p-STAT3 were assessed using immunohistochemistry, magnification: 20X, Scale bar: 100μm. Total RNA was used to measure the relative mRNA levels of (C) Cyr61, (D) HMGB1, and (E) VEGF by RT-PCR. The values are expressed as the mean ± SEM of n = 6 animal per group. Each data point (n = 6 per group) represents the average of three technical replicates. Mean difference and confidence intervals are shown in the Supplementary Table 1 . Statistical significance was determined by one-way ANOVA followed by Bonferroni’s post-hoc test: #p < 0.05, ##p < 0.01 and ### p < 0.01 verses control mice. * p < 0.05, ** p < 0.01 and *** p < 0.01 verses IMQ-induced psoriasis mice. Abbreviations: Cyr61, cysteine-rich angiogenic inducer 61; HMGB, High mobility group box 1; VEGF, Vascular endothelial growth factor.
