Abstract

The invention discloses a molecular marker for early warning of atherosclerosis. A method comprises the following steps that (1) the influence of Hcy (Homocysteine) with different concentrations on endothelial cell proliferation is detected by an MTT colorimetric method, and a proper concentration is screened out; (2) after cells is intervened with the Hcy with optimal concentration, cell viability staining detection is carried out; (3) after the cells is intervened with the Hcy with optimal concentration, the apoptosis of endothelial cells is detected by flow cytometry; (4) after the cells isintervened with the Hcy with optimal concentration, the expression of LncRNA (long noncoding RNA) DINO (Damage Induced Noncoding) is detected through fluorescent quantitative PCR in real time; (5) transfecting of the LncRNA DINO siRNA is carried out, after the LncRNA DINO is interfered, and then cell viability staining detection is carried out; (6) LncRNA DINO siRNA is constructed, after the LncRNA DINO is interfered, and the apoptosis of endothelial cells is detected by flow cytometry; and (7) LncRNA DINO siRNA is constructed, after the LncRNA DINO is interfered, and then the expression of apoptosis-related protein is detected by protein immunoblotting. A novel molecular target for early diagnosis and early warning of atherosclerosis is provided, and a new direction is provided for treatment.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a molecular marker for early warning of atherosclerosis and its application. Background technique [0002] Atherosclerosis (Atherosclerosis, AS) is a chronic progressive disease that is characterized by endothelial cell apoptosis, smooth muscle cell proliferation, and foam cell formation, and is prone to occur in large and medium-sized arteries. Major cause of high morbidity and mortality. In recent years, with the rapid development of society and economy, people's living standards have been continuously improved. Affected by factors such as changes in diet structure and increased work pressure, the incidence of AS (atherosclerosis) has shown an increasing trend year by year and is gradually becoming younger. It can be seen that early detection, prevention and delay of the process of atherosclerosis are the top priority in the field of clinical science today. There...
