Cordycepin ameliorates diabetic nephropathy injury by activating the SLC7A11/GPX4 pathway
Background
Cordycepin (CRD) has been identified to alleviate diabetes-induced injuries and complications including diabetic nephropathy (DN). Here, this work focused on probing the specific effects and potential mechanisms of CRD on DN progression.
Methods
High glucose (HG)-induced mouse podocyte cell line (MPC5) was used for in vitro functional analyses. Cell proliferation and apoptosis were determined using cell counting kit-8 assay, 5-ethynyl-2′-deoxyuridine assay, and flow cytometry, respectively. ELISA analysis detected inflammatory factors. Cell ferroptosis was assessed by measuring the levels of Fe2+, glutathione, reactive oxygen species, and malonaldehyde.
Results
CRD treatment suppressed HG-induced apoptosis, inflammation, and ferroptosis in podocytes. CRD treatment elevated SLC7A11 and GPX4 expression in HG-treated podocytes. The overexpression of SLC7A11 or GPX4 suppressed HG-evoked apoptosis, inflammation, and ferroptosis in podocytes. Moreover, the silencing of SLC7A11 or GPX4 abolished the protective effects of CRD on HG-treated podocytes. Moreover, CRD ameliorated renal structure injury and inflammation in STZ-induced diabetic mice by modulating SLC7A11 or GPX4 expression.
Conclusions
Cordycepin suppressed HG-induced apoptosis, inflammation, and ferroptosis in podocytes in vitro, and ameliorated renal injury and inflammation in STZ-induced diabetic mice by activating the SLC7A11/GPX4 pathway.
期刊介绍：
Journal of Diabetes Investigation is your core diabetes journal from Asia; the official journal of the Asian Association for the Study of Diabetes (AASD). The journal publishes original research, country reports, commentaries, reviews, mini-reviews, case reports, letters, as well as editorials and news. Embracing clinical and experimental research in diabetes and related areas, the Journal of Diabetes Investigation includes aspects of prevention, treatment, as well as molecular aspects and pathophysiology. Translational research focused on the exchange of ideas between clinicians and researchers is also welcome. Journal of Diabetes Investigation is indexed by Science Citation Index Expanded (SCIE).
