O‐linked β‐N‐acetylglucosamine transferase knockout (OGTKO) increases cardiomyocyte cross‐sectional area during established hypertrophy in sham and transverse aortic constriction (TAC) hearts. Representative sections from the indicated established hypertrophy groups stained for wheat germ agglutinin and DAPI are shown in (A through D). E, Quantification of the cross‐sectional areas for the experimental groups. Values are expressed as mean±standard error of the mean. n=4 per group. Red bar indicates 50 μm. *P<0.05 between groups indicated with the bar.
