Abstract

Andrographolide (Andro) is an active compound extracted from Andrographis, which has protective anti-inflammatory effects. But, its pathological role in coronary heart disease (CHD) is unclear, the aim of this study is to investigate the therapeutic effect of Andro in CHD and explore its potential mechanism. Here, we established a mouse model of CHD, and rats were randomly divided into 5 groups (n=10): sham, Andro (50 mg/kg), CHD, CHD + Andro (10 mg/kg), and CHD + Andro (50 mg/kg). HE staining was employed to evaluate the pathological changes of myocardial injury cardiac injury. The serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), highdensity lipoprotein cholesterol (HDL-C), nitric oxide (NO), TXA2, ET-1, and prostaglandin I2 (PGI2) were detected by ELISA assay. Myocardial inflammation and the interaction between Andro and PPAR-α/NF-κB axis was measured using western blot. Compared with CHD groups, Andro preserved cardiac injury and decreased the levels of TC, TG, and LDL-C while increasing the level of HDL-C. In addition, Andro also reduced the levels of TNF-α, MCP-1, hs-CRP and IL-1β by shifting the macrophage phenotype and attenuated the endothelial dysfunction by incre...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

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
