Figure 3.
Northern blots showing the expression of four differentially expressed genes in the left ventricular tissues of six additional patients with hypertrophic cardiomyopathy (HCM). Lanes 1 and 2 represent the left ventricular samples obtained from normal hearts (donor hearts not used for transplantation). Lanes 3 through 8 represent the left ventricular tissues obtained from patients with HCM. Expression levels of skeletal muscle alpha-actin (A), myosin light chain 2A (B) and GTP-binding protein Gs-alpha subunit (C) were increased in all hearts with HCM, as compared with the control hearts. Expression levels of four-and-a-half LIM domain protein 1 (D) were increased by less than twofold in 4 out of 6 hearts with HCM.
