ACSL4 and diabetic kidney disease: We built a circRNA-miRNA-ferroptosis-related mRNA network in this research and discovered that the biological activity of circ-0069561 was tightly linked to several ferroptosis-related genes, including ACSL4, ALOX12, ALOX15, etc. The KEGG pathway investigation suggests that ferroptosis may be involved in the pathophysiology of DKD.
