Myocardial fibrosis in wild‐type (WT) and Myeloid differentiation protein 1 (MD1)‐knock‐out mice 4 weeks after saline or aldosterone infusion. (A) Representative western blots of MD1 expression in left atrial tissues from WT and MD1‐KO mice (n = 6). (B) Representative Masson trichrome staining. Original magnification ×400; (C) myocardial fibrosis area (n = 4); and (D,E) representative western blots and statistical analysis of the fibrosis‐related proteins levels (n = 4). Data are expressed as mean ± standard error of the mean. ^* P < 0.05 vs. WT‐Sal group and ^# P < 0.05 vs. WT‐Aldo group.
