Abstract
Septic cardiomyopathy is a severe cardiovascular disease with a poor prognosis. Previous studies have reported the involvement of ferroptosis in the pathogenesis of septic cardiomyopathy. SGLT2 inhibitors such as dapagliflozin have been demonstrated to improve ischemia-reperfusion injury by alleviating ferroptosis in cardiomyocyte. However, the role of dapagliflozin in sepsis remains unclear. Therefore, our study aims to investigate the therapeutic effects of dapagliflozin on LPS-induced septic cardiomyopathy. Our results indicate that dapagliflozin improved cardiac function in septic cardiomyopathy experimental mice. Mechanistically, dapagliflozin works by inhibiting the translation of key proteins involved in ferroptosis, such as GPX4, FTH1, and SLC7A11. It also reduces the transcription of lipid peroxidation-related mRNAs, including PTGS2 and ACSL4, as well as iron metabolism genes TFRC and HMOX1.
期刊介绍：
The Journal of Bioenergetics and Biomembranes is an international journal devoted to the publication of original research that contributes to fundamental knowledge in the areas of bioenergetics, biomembranes, and transport, including oxidative phosphorylation, photosynthesis, muscle contraction, as well as cellular and systemic metabolism. The timely research in this international journal benefits biophysicists, membrane biologists, cell biologists, biochemists, molecular biologists, physiologists, endocrinologists, and bio-organic chemists.
