Liuwei Dihuang Prevents Human Umbilical Vein Endothelial Cells Senescence via the JPX-STING-IRF3 Pathway
Background: Cellular senescence plays a crucial role in age-related diseases. Endothelial senescence is closely associated with age-related vascular disorders. This study aimed to reveal the role of traditional Chinese medicine Liuwei Dihuang (LWDH) in anti-endothelial cell senescence.
Methods: Human umbilical vein endothelial cells (HUVECs) were exposed to LPS treatment to induce senescence. Senescence-associated β-galactosidase (SA-β-gal) positive staining, p53 and p16 expression, BrdU staining, and relative telomere length (RTL) experiments were conducted to estimate LPS-induced cellular senescence of HUVECs. Real-time qPCR analysis was performed to identify differentially expressed lncRNAs in LPS-induced senescent HUVECs before and after treatment with LWDH. Bioinformatics analysis and ChIP assay were conducted to explore the mechanism of JPX in the anti-endothelial cell aging effect of LWDH.
Results: We first discovered that lncRNA JPX and STING-IRF3 pathways are involved in the process of anti-endothelial senescence of LWDH. Mechanistically, LWDH could reverse abnormally elevated JPX induced by LPS and inhibit the activation of STING, as well as the interaction between JPX and STING.
Conclusion: Overall, our study explores the potential therapeutic value of LWDH and provides key insights into the potential avenues for preventing and treating HUVECs senescence.
