CSN5 attenuates Ang II-induced cardiac hypertrophy through stabilizing LKB1

CSN5 is a critical subunit of the COP9 signalosome (CSN) and has been involved in various cellular processes, but little is known about the role of CSN5 in cardiac disease. In the present study, we found that the expression of CSN5 was increased in Angiotensin II (Ang II)-induced cardiac hypertrophic mice hearts and Ang II-treated cardiomyocytes. We also observed that overexpression of CSN5 significantly inhibited Ang II-induced cardiac...
