TGFBR3 attenuates the pro-EMT effects caused by miR-19a and miR-424 in cardiac fibroblasts. (A, B) Scale bars, 10 µm. Transwell assay indicates that TGFBR3 abolished miR-19a/miR-24-mediated migration. +TGFBR3: co-transfection of miR-19a or miR-424 and TGFBR3, +EV: co-transfection of miR-19a or miR-424 and empty vector (EV), n = 4. Effects of TGFBR3 on the EMT marker proteins, E-Cad (C, D) and Vim (E, F), following transfection with miR-19a or miR-424. (G, H) TGFBR3 reduces p-p65 expression induced by miR-19a or miR-424. n = 4, *p < 0.05 vs. control; #
p < 0.05 vs. miR-19a or miR-424 alone.
