Zhuyu Pills regulate p53/SLC7A11 signaling pathway-mediated oxidative damage and ferroptosis to treat atherosclerosis (PubMed, Zhongguo Zhong Yao Za Zhi)
Compared with the model group, low-, medium-, and high-dose Zhuyu Pills and atorvastatin calcium reduced the aortic plaque area, collagen deposition, liver lipid deposition, lipid droplets, and epididymal adipocyte volume, lowered the levels of iron ion and MDA and elevated the levels of SOD and GSH-Px in the serum, inhibited the expression of p53 and COX2, up-regulated the protein and mRNA levels of FTH1, SLC7A11, and GPX4, and down-regulated the mRNA levels of PTGS2 and NOX1 in the aorta. In conclusion, Zhuyu Pills exert definite therapeutic effect on aortic plaque in AS mice by regulating the p53/SLC7A11 signaling pathway to alleviate oxidative damage and inhibit ferroptosis.
