DNMT1 and hydrops fetalis: It was demonstrated that DNMT1 promotesthe methylation of the promoter region of miR-152-3p, thereby reducing itsexpression and resulting in the inhibition of mitophagy in H9c2 cells.Furthermore, the depletion of DNMT1 conferred protection against HF in ratsthrough a mechanism dependent on miR-152-3p, ETS1, and RhoH [436].
