The classical Wnt/catenin signaling pathway has been implicated in numerous developmental processes, and mutationsin this pathway happen to be observed in degenerative illnesses, like Alzheimer’s illness and in several sorts of cancer, which include nonsmall cell lung cancer (3336). The Wnt/catenin signaling pathway can be activated by extremely conservedGAN et al: INFLAMMATION AND APOPTOSIS OF HUVECs ARE REGULATED BY DKK1/CCN1 SIGNALINGWnt proteins (37). A recent study established the association involving the Wnt/catenin signaling pathway and atheroscle rosis (38). Also, research has revealed that activation of catenin could induce elevated expression levels of CCN1, and inhibition of Wnt/catenin signaling could attenuate endothe lial dysfunction (19,39). Hence, the present study hypothesized that Wnt/catenin signaling may regulate the expression of CCN1 to defend endothelial cells from PAinduced injury. DKK1, which can antagonize Wnt signaling by binding to LRP5/6 (34), was also assessed in the present study. Within the present study, DKK1 expression was inhibited, whereas Wnt/ catenin signaling was activated when HUVECs have been treated with increasing doses of PA. Overexpression of DKK1 inhibited activation from the Wnt/catenin signaling in PAtreated HUVECs and further decreased the expression levels of CCN1. Conversely, silencing DKK1 activated the Wnt/catenin signaling pathway and improved CCN1 expres sion. In conclusion, the present study supplied proof that DKK1/CCN1 may possibly regulate PAinduced inflammation and apoptosis of HUVECs; on the other hand, the effects of DKK1/CCN1 must be further verified in animal experiments, which could deliver novel biomarkers for clinical diagnosis and therapeutic techniques for CVDs.

The demands on endothelial cells (EC) differ below different physiological states. EC are nonthrombogenic, express blood elements, regulate transfer of nutrients and waste between blood and tissues, regulate immune cell activation and recruitment, and below circumstances of growth or tissue repair, undergo angiogenic sprouting to produce new vessels. How EC switch from the quiescent, homeostatic maintenance phenotype for the proliferative, migratory, proangiogenic phenotype is at present the concentrate of intense study because the regulation of this switch has implications for improvement, wound healing, diabetic retinopathy and tumor development. Recently, we identified the inflammatory mediator TNF as a crucial effector in wound healing that c.
