PHF19 and cardiac hypertrophy: The latest research showed that constitutive photomorphogenic 9 signalosome complex subunit 6 (CSN6) and plant homeodomain finger protein 19 (PHF19) exacerbate the pathological myocardial hypertrophy induced by Ang II by inhibiting the expression of SIRT2, and the overexpression of SIRT2 can reduce the effect of CSN6 in promoting myocardial hypertrophy.30, 31
