TP inhibits EndMT in cardiac remodeling models. (A–D) Western blot analysis of CD31, VE-Cadherin and α-SMA protein expression in mouse heart tissue (n = 6). (E–H) Western blot analysis of Slug, Snail and Twist protein expression in mouse heart tissue (n = 6). (I–L) Western blot analysis of CD31, VE-Cadherin and α-SMA in EN (HCAEC) (n = 6). (M–P) Western blot analysis of Slug, Snail and Twist in EN (HCAEC) (n = 6). All the values are presented as mean ± SD. #P < 0.05, ##P < 0.01 compared with Sham or Ctl group; *P < 0.05, **P < 0.01 compared with TAC or TGF-β1 group. The original blots were provided in supplementary data as Supplementary Fig. S4.
