HIF1A and renal fibrosis: Lauric acid (LA) and caprylic acid (CA) were bioactive components within QXLZY regulating the TLR4/HIF-1α pathway in CKD.<h4>Conclusion</h4>QXLZY inhibits ferroptosis by downregulating the TLR4/HIF-1α pathway, thereby alleviating renal fibrosis and improving CKD, with LA and CA potentially playing significant roles.
