“…All reactions were normalized using β‐actin as the endogenous control. Data were analysed using the 2 −∆∆Ct method 9 . The fold changes of each target mRNA expression relative β‐action under experimental or control conditions were calculated based on the threshold cycle (CT) as r = 2 −Δ(ΔCT) , where ΔCT = CT (target) − CT (β‐action) and Δ(ΔCT) = ΔCT (experimental) − ΔCT (control).…”

MOTS-c, a mitochondrial-derived peptide (MDP), has been shown to have multiple biological activities such as antioxidation, anti-inflammation, and anti-apoptosis properties. In the present study, we aimed at evaluating the therapeutic effect of MOTS-c peptide in an animal model of heart failure. The heart failure mouse model was made by transverse aortic constriction (TAC) operations. The MOTS-c peptide was administrated subcutaneously by using an osmotic pump. At the end of the animal experiment, cardiac function was evaluated by echocardiography, and heart tissues were subjected to histological and molecular analysis. In vitro cultured H9C2 cells were used to test the effects of MOTS-c overexpression on cell death in response to H 2 O 2 stimulation. Our study showed that MOTS-c peptide attenuated TAC-induced cardiac dysfunction and remodelling. In addition, the MOTS-c peptide reduced the inflammatory response and upregulated the antioxidant capacity, coupled with the activation of the AMPK pathway in the heart of the TAC mouse model. In in vitro cultured cardiac cells, overexpression of MOTS-c was shown to activate the AMPK pathway and protect cell apoptosis in response to H 2 O 2 stimulation. Taken together, our study suggested that MOTS-c peptides may have therapeutic potential in treating HF.
