Abstract

To investigate the effect of micro ribonucleic acid (miR)-210 on the apoptosis of vascular endothelial cells in arteriosclerosis obliterans (ASO) through the Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway. In the present work, the vascular endothelial cells in ASO patients were selected as objects of study, the cell lines with miR-210 interference and overexpression were constructed with the Crisp/Case9 technique for subsequent experiments as experimental group, and the aortic endothelial cells of a healthy human were used as control group. First, the changes in the transcriptional and translational levels of such genes as JAK2 and STAT3 in the JAK-STAT signaling pathway in cell lines with miR-210 interference and overexpression were detected via fluorescence quantitative Polymerase Chain Reaction (qPCR) and Western blotting. The changes in the transcriptional and translational levels of nitric oxide synthase (NOS) in cells were detected in experimental group and control group to clarify the regulatory effect of miR-210 on the JAK-STAT signaling pathway. At the same time, the cell proliferation in experimental group and control group was observed via methyl thiazolyl tetrazolium (MTT)...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
