Despite these advances, critical gaps remain: non-coding RNAs (ncRNAs) such as long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and microRNAs (miRNAs) have only been sporadically implicated in this network (e.g., miR-125a targeting SLC7A11 in diabetic nephropathy), and their cell type-specific roles in renal ferroptosis remain largely uncharacterized. The gene discussed is SLC7A11; the disease is diabetic kidney disease.
