Left ventricular mRNA expression of typical markers of cardiac hypertrophy such as α-smooth muscle actin (α-SMA), atrial natriuretic and B-type natriuretic peptides (ANP and BNP) tended to be higher after MI (statistically significant only for BNP), but again no difference between WT and VDR mutant mice. Here, ACTA1 is linked to myocardial infarction.
