Downregulation of cingulate PRMT1 is necessary to develop peripheral hypersensitivity. (A) Upper schematics of AAV8 vectors engineered to overexpress PRMT1 and an eGFP Ctrl. Lower experimental paradigm for behavioral testing. (B) Illustration of bilateral AAV8-Prmt1 OE virus in the mouse ACC. (C) PWT tests conducted in both sham and CPN-ligated mice injected either Prmt1 Ctrl or OE virus in ACC (Sham Prmt1 Ctrl, n = 9; Sham Prmt1 OE, n = 8; CPN Prmt1 Ctrl, n = 9; CPN Prmt1 OE, n = 8, Two-way RM ANOVA, interaction: F(15;150) = 2.0, p < 0.05, Time: F(5;150) = 2.70, p < 0.05, Prmt1 Ctrl vs. Prmt1 OE: F(3;150) = 15.60, p < 0.01). (D) PWTs measured in both saline-and CFA-injected mice either with Prmt1 Ctrl or OE virus in ACC (Saline Prmt1 Ctrl, n = 6; Saline Prmt1 OE, n = 6; CFA Prmt1 Ctrl, n = 8; CFA Prmt1 OE, n = 10, Two-way RM ANOVA, interaction: F(15;130) = 3.40, p < 0.01, Time: F(5;130) = 4.72, p < 0.01, Prmt1 Ctrl vs. Prmt1 OE: F(3;130) = 11.41, p < 0.01). Data are represented as mean ± SEM; ns, not significant.
