Measurement of mRNA levels with RT-PCR to assess induction of fetal gene program, as well as hypertrophy (Rcan1) and fibrosis (Col1a1, Ctgf); n = 8 per group, except n = 7 in Wt TAC group. Myh6/Myh7: *P = 0.0001 versus Wt sham, #P = 0.00001; Anp: *P = 0.0005 versus LXRα-Tg sham, #P = 0.02; Bnp: *P = 0.0006 versus Wt sham, **P = 0.009 versus LXRα-Tg sham, #P = 0.03; Acta1: §P < 0.00001 versus Wt sham, *P = 0.01 versus LXRα-Tg sham, #P = 0.001; Rcan1: **P = 0.00004 versus Wt sham, *P = 0.05 versus LXRα-Tg sham, #P = 0.04; Col1a1: *P = 0.00003 versus Wt sham; Ctgf: §P < 0.00001 versus Wt sham, #P = 0.00001.
