The study evaluates the role of Jmjd4 in dilated cardiomyopathy (DCM), a heart condition with no obvious genetic cause. The study found that Jmjd4 expression is decreased in DCM patients, and inducing its deletion in cardiomyocytes led to spontaneous DCM with impaired mitochondrial respiration. The study also found that Jmjd4 interacts with Hsp70 to mediate the degradation of Pkm2, a protein that accumulates in hearts with Jmjd4 deleted, through chaperone-mediated autophagy. The study suggests that Jmjd4 and Pkm2 may be therapeutically targeted to treat DCM and other cardiac diseases with metabolic dysfunction.
