Overexpressed SIRT6 attenuates cisplatin-induced acute kidney injury by inhibiting ERK1/2 signaling. Academic Article uri icon

Overview

abstract

  • Sirtuin 6 (SIRT6) is a NAD+-dependent deacetylase associated with numerous aspects of health and physiology. Overexpression of SIRT6 has emerged as a protector in cardiac tissues against pathologic cardiac hypertrophy. However, the mechanism of this protective effect is not fully understood. Here, both in vivo and in vitro results demonstrated that SIRT6 overexpression can attenuate cisplatin-induced kidney injury in terms of renal dysfunction, inflammation and apoptosis. In addition, SIRT6 knockout aggravated kidney injury caused by cisplatin. We also found that SIRT6 bound to the promoters of ERK1 and ERK2 and deacetylated histone 3 at Lys9 (H3K9) thereby inhibiting ERK1/2 expression. Furthermore, inhibition of ERK1/2 activity eliminated aggravation of kidney injury caused by SIRT6 knock out. Thus, our findings uncover the protective effect of SIRT6 on the kidney and define a new mechanism by which SIRT6 regulates inflammation and apoptosis. This may provide a new therapeutic target for kidney injury under stress.
