Cardiomyocytes from ae3-/- mice have been protected from increases in cell surface location, protein synthesis, and fetal gene reactivation in response to hypertrophic stimulation. Steady-state cardiomyocyte pHi in ae3-/- mice was comparable to WT, but slower to recover from imposed intracellular alkalosis. Our findings demonstrate that AE3 is significant in hypertrophic signaling pathways activated by PE and ANGII, possibly acting through the hypertrophic transport metabolon. Pharmacologically targeting AE3 activity inside the occasion of hypertrophy is an attractive method to treat heart failure patients. Extra filesAdditional file 1: Figure S1. Impact of hypertrophic stimulation on cardiomyocyte CAII protein expression. Cardiomyocytes isolated from wildtype (ae3+/+) and knock-out (ae3-/-) mice hearts were cultured for 18 h and subjected to vehicle-alone (CON), angiotensin II (ANGII) and phenylephrine (PE) treatment for further 24 h. Lysates prepared from cardiomyocytes were probed for CAII expression by immunoblotting. Immunoblots have been stripped and probed for -actin.
