We also found no differences in cardiac hypertrophy between control and CM‐G4‐KO mice 3 h and 7 days after cryoinjury or sham surgery when analyzing the heart weight/body weight ratio (HW/BW), the cardiomyocyte cross‐sectional area, or hypertrophy‐related gene expression (Nppa, Nppb; Fig EV2E–H). The gene discussed is NPPA; the disease is cardiac hypertrophy.
