Coronary Artery Disease I: Introduction

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Background:

Coronary artery disease (CAD) is linked to abnormal lipid metabolism.
Transforming growth factor-ß (TGF-ß) and its receptor (TGF-ßR) can suppress CAD progression via the SMAD pathway.
Endoglin (TGF-ßRIII), a TGF-ßR family protein, is involved in immune regulation, but its role in atherosclerosis is unclear.

Purpose of the Study:

To clarify the pathophysiological effects of endoglin on atherosclerosis development.
To explore the signaling pathway mechanisms of endoglin in atherosclerosis.

Main Methods:

Downloaded GEO datasets for functional analysis of SMAD activity and TGF-ß receptor expression in familial hyperlipidaemia monocytes.
Examined endoglin's effect on endothelial cell proliferation, migration, and apoptosis using gene disruption in HUVECs and western blotting.
Analyzed sequencing data to identify endoglin-regulated genes and pathways.

Main Results:

Interference with endoglin promotes vascular endothelial cell proliferation and migration.
Interference with endoglin significantly inhibits vascular endothelial cell apoptosis.
Endoglin interference particularly upregulates VEGFB expression in vascular endothelial cells.

Conclusions:

Endoglin regulates PI3K-Akt, Wnt, TNF, and cellular metabolism pathways by activating the SMAD pathway in vascular endothelial cells.
RAB26, MR1, CCL2, SLC29A4, IBTK, VEGFB, and GOLGA8B are critical genes regulated by endoglin.
Endoglin interacts with proteins like CCL2 and SEPRINE1 in plaque formation pathways, suggesting endoglin modulation can alter coronary atherosclerosis progression.
