Upregulated miR-133a-3p and downregulated PSAT1 alleviate the pathological changes of IA tissues. a Hemodynamic changes at each time point after successful modeling in rats. b Changes of IA tissue after transfection. n = 12, *P < 0.05 vs. the normal group. #P < 0.05 vs. the mimic NC group. &P < 0.05 vs. the si-NC group. +P < 0.05 vs. the miR-133a-3p mimic group. Measurement data were depicted as mean ± standard deviation, and data were assessed by one-way analysis of variance followed by Tukey’s post hoc test.
