A–C, quantitative RT-PCR analysis of expression of the cardiomyopathy marker genes in 3-month-old NTG, α-Tm E180G, α-Tm S283A, and DMTG hearts. For NTG, n = 12; for E180G, n = 8; for S283A, n = 8; and for DMTG, n = 10. *, versus NTG, p < 0.05; #, versus α-Tm E180G, p < 0.05; @, versus α-Tm S283A, p < 0.05. Error bars represent S.E.
