ABSTRACT
OBJECTIVES: To investigate the effects of propranolol on the proliferation, apoptosis, migration, and tube formation ability of human umbilical vein endothelial cells (HUVEC), as well as its impact on the expression of sex-determining region Y-box 18 (SOX18), matrix metalloproteinase-7 (MMP-7), and vascular endothelial growth factor A (VEGFA).
METHODS: HUVEC were treated with different concentrations of propranolol, and cell viability was assessed using the CCK-8 method to determine the optimal concentration and treatment duration. The experiment consisted of a control group and groups treated with different concentrations of propranolol (50, 100, 150 μmol/L). Apoptosis, migration, and tube formation of HUVEC were observed using flow cytometry, wound healing assays, and tube formation assays. Western blot and real-time quantitative PCR were used to detect the expression levels of SOX18, MMP-7, and VEGFA proteins and mRNA.
RESULTS: Compared to the control group, the apoptosis rate in the propranolol treatment groups increased significantly (P<0.05), and it rose significantly with increasing drug concentration (P<0.05). The wound healing rate decreased in the propranolol treatment groups, and both the number of tube formation nodes and total tube length were reduced (P<0.05). The expression levels of SOX18, MMP-7, and VEGFA proteins and mRNA were downregulated in the propranolol treatment groups (P<0.05).
CONCLUSIONS: Propranolol can inhibit the proliferation, migration, and tube formation ability of HUVEC and promote cell apoptosis, resulting in decreased expression levels of SOX18, MMP-7, and VEGFA.
