Investigating the role and mechanism of stress induced protein Sesn2 in aged-related adaptive response to cardiac ischemia reperfusion injury

Purpose: to reveal the myocardium transcriptomic profile shift pattern before/after Ischemia Reperfusion stress in young, aged, and Sesn2-knockout mice. The goals of this study are to compare the transcriptomic shift pattern among young, aged, and Sesn2-knockout to explore the caridoprotective mechanism of Sesn2 in Ischemia Reperfusion stress and the critical roles of Sesn2 in age-related adapting response to Ischemia Reperfusion stress. Methods: Myocardium transcriptome profiles of young (3-4 months) wild-type, aged (24-26 months) wild-type, and Sesn2-knockout (3-4 months) mice in normal physiological and Ischemia Reperfusion stressed conditions. Results: Sesn2 is critical to repress inflammation and maintain metabolic and mitochondria homeostasis in hearts under Ischemia Reperfusion stress, especially to aged hearts. Myocardium transcriptome profiles of young (3-4 months) wild-type, aged (24-26 months) wild-type, and Sesn2-knockout (3-4 months) mice in normal physiological and Ischemia Reperfusion stressed conditions.
