Abstract

The use of propranolol for the treatment of infantile hemangioma (IH) has been widely investigated in recent years. However, the underlying therapeutic mechanism of propranolol for the treatment of IH remains poorly understood. The aim of the present study was to investigate the expression of proteins regulated by cellular tumor antigen p53 (p53) in associated apoptosis pathways in IH endothelial cells (HemECs) treated with propranolol. Furthermore, the present study aimed to investigate the exact apoptotic pathway underlying the therapeutic effect of propranolol against IH. In the present study, HemECs were subcultured and investigated using an inverted phase contrast microscope, immunocytochemical staining and a scanning electron microscope (SEM). Experimental groups and blank control groups were prepared. All groups were subjected to drug treatment. A high p53 expression model of HemECs was successfully established via transfection, and a low p53 expression model of HemECs was established using pifithrin‑α. The apoptosis rate of each group was determined using Annexin V‑fluorescein isothiocyanate/propidium iodide double staining and flow cytometry. The expression levels of downstream proteins regulated by p53 [tumour necrosi...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
