JAZF1 plasmids were successfully transfected into CMECs. (a), relative mRNA levels of JAZF1 in response to the treatment of JAZF1 or JAZF1 shRNA; (b), relative protein levels of JAZF1 in response to the treatment of JAZF1 or JAZF1 shRNA; (c), the gray value of JAZF1 protein band in response to the treatment of JAZF1 or JAZF1 shRNA; CMECs, cardiac microvascular endothelial cells; NC, negative control; shRNA, short hairpin RNA; JAZF1, the juxtaposed with another zinc finger protein 1; *, p < 0.05 vs. the normal group; #, p < 0.05 vs. the blank, empty vector and NC shRNA group.
