PPARGC1A and familial dilated cardiomyopathy: Having found specific CM-dependent increases in expression of four genes (CD36, HFABP, PPARA and PGC1A) involved in FA metabolism and HF-related increases in three Ca2+-handling genes (TPCN1, TPCN2 and IP3R1), we next compared gene expression levels by calculating Spearman correlation coefficients within CTL, ICM (n = 16) and DCM (n = 20) groups; any correlation with p<0.05 in CTL and p<0.01 in ICM and DCM was selected for further consideration.
