GSE263965 Deubiquitinase USP29 Ameliorates Pathological Cardiac Hypertrophy Through Inhibiting TAK1

In this study, we elucidated the role of Ubiquitin-specific protease 29 (USP29), a deubiquitinase, in pressure overload-induced cardiac hypertrophy. Genetic knockout of USP29 in mice significantly exacerbated TAC-induced heart hypertrophy, dysfunction, and fibrosis; whereas overexpression of USP29 in cardiomyocytes attenuated the hypertrophic response. Similarly, USP29 markedly alleviated PE-induced hypertrophy of primary neonatal rat cardiomyocytes. Mechanistically, the cardio-protective effects mediated by USP29 were attributed to its suppression of transforming growth factor β-activated kinase 1 (TAK1)-JNK/P38 signaling pathway activation. Collectively, our study suggests that targeting either USP29 or its interaction with TAK1 could represent an innovative therapeutic strategy for treating heart failure and cardiac hypertrophy.
