Abstract
OBJECTIVE: Infantile hemangiomas (IHs) are the most common benign tumors in infancy. The purpose of this study was to study the effects of propranolol on the function of human umbilical vein endothelial cells (HUVECs), in order to preliminarily elucidate the mechanism of propranolol in the treatment of IHs. METHODS: HUVECs were treated with different concentrations of propranolol (30 μM, 60 μM, 90 μM, and 120 μM) with or without VEGF. Their proliferation, migration, invasion, adhesion, and tube formation ability were tested by using CCK-8, wound healing assay, transwell, cell adhesion assay, and tube formation assay. The expressions of HUVECs angiogenesis signaling molecules pERK/ERK, pAKT/AKT, p-mTOR/mTOR, and pFAK/FAK were detected by Western blot. RESULTS: Compared with the control group, propranolol could significantly inhibit the proliferation, migration, invasion, adhesion, and tube formation of HUVECs. Further studies showed that it could not only inhibit the migration, invasion, and tube formation ability of HUVECs after VEGF induction but also inhibit the phosphorylated protein expressions of angiogenesis-related signaling molecules like AKT, mTOR, ERK, and FAK in HUVECs, with a concentration-dependent inhibitory effect. CONCLUSION: Propranolol can inhibit the proliferation, migration, invasion, adhesion, and tube formation of hemangioma endothelial cells; block VEGF-mediated angiogenesis signaling pathway; suppress the expressions of downstream angiogenesis-related signaling molecules; and ultimately achieve the effect of treatment of IHs.
