Researches have demonstrated that trans-fatty acids are related to the progression of atherosclerosis, but the underlying mechanism is not clear till now. In the presented study, two-dimensional electrophoresis based proteomics was used to discover the role of elaidic acid in atherosclerosis. In human umbilical vein endothelial cells (HUVEC), twenty-two and twenty-three differentially expressed proteins were identified in low (50 μmol/L) and high (400 μmol/L) concentration elaidic acid simulated groups, respectively, comparing with the control group. The expressions of some selected proteins (PSME3, XRCC5, GSTP1, and GSTO1) were validated by qRT-PCR analysis. Western blotting analysis further confirmed that elaidic acid downregulated the expression of PSME3 and XRCC5. Moreover, P53, the downstream protein of PSME3, was further investigated. Results demonstrated that a variety of proteins, many of which were related to oxidative stress, apoptosis, and DNA damage, were involved in the elaidic acid induced atherosclerosis. Furthermore, P53 was demonstrated to regulate the atherosclerosis through cell cycle arrest and apoptosis pathway.

Background/Aims: To investigate the effect of propranolol on cobalt chloride (CoCl2)-induced hypoxic proliferation in human umbilical vein endothelial cells (HUVECs). Methods: CoCl2 was administrated to HUVECs to mimic hypoxic proliferation in infantile hemangioma. The proliferation of HUVECs was detected by Cell Counting Kit-8. Effects of propranolol on apoptosis and expressions of cell cycle-related genes, CDK4 and cyclin D1, were detected by flow cytometry and RT-PCR respectively. The release of vascular endothelial growth factor (VEGF) and lactate dehydrogenase (LDH) was measured by enzyme-linked immunosorbent assay. Results: Propranolol significantly inhibited the CoCl2-induced hypoxic proliferation of HUVECs in a dose-dependent manner, and also induced apoptosis and suppressed the expression of CDK4 and cyclin D1. Propranolol also decreased the release of VEGF and LDH in the supernatant. Conclusions: Propranolol could inhibit CoCl2-induced hypoxic proliferation of HUVECs through inducing apoptosis and cell cycle arrest.
