Advantages

PARP16 deficiency rescues cardiac dysfunction and ameliorates TAC-induced cardiac hypertrophy and fibrosis in vivo

Overexpression of PARP16 exacerbates hypertrophic responses including augmented cardiomyocyte surface area and upregulation of fetal gene expressions

PARP16 interacts with IRE1α and ADP-ribosylates IRE1α, mediating hypertrophic responses via activating the IRE1α-sXBP1-GATA4 pathway
