From: Cardiac thromboxane A2 receptor activation does not directly induce cardiomyocyte hypertrophy but does cause cell death that is prevented with gentamicin and 2-APB

U46619 does not increase gene markers associated with pathological hypertrophy. Exposing AVCMs to increasing concentrations of U46619 (0.1-10 μM) did not increase the expression of early growth response 1 (EGR1) gene or the hypertrophy-associated genes atrial natriuretic peptide (ANP) after 24 h when compared to vehicle (p > 0.05). Forty-eight-hour treatment with U46619, did not increase the expression of other hypertrophy genes β-myosin heavy chain (β-MHC) and skeletal muscle α-actin (SkAct) when compared to vehicle (n = 4-5; p > 0.05). There was also no significant increase in these genes with U46619 treatment in HL-1 cardiomyocytes.
