Castration-induced carotid wall thinning and aortic collagen deposition. Castration decreased carotid wall thickness in (A). XYM (t = 4, df = 13; P = 0.001) and B XXM (t = 3, df = 17; P = 0.02) mice. The carotid wall-to-lumen ratio was significantly different in (C). XYM (t = 3, df = 17; P = 0.009) but not in (D). XXM (t = 2, df = 12; P > 0.09). E. Gonadectomy significantly increased collagen area fraction XXM (t = 3, df = 16; P = 0.02), but not XYM (t = 0.8, df = 16; P = 0.8) mice. F Aortic α smooth muscle was significantly downregulated in XXM mice after castration (P = 0.005). However, G Col1a1 was increased in gonadectomized XX mice (P = 0.01).
