Molecular Cell Biology

Paper Summary:

In this article, the writer looks at the molecular biology of the cholesterol transport from arterial walls to the liver for biliary excretion. The paper looks at all the genes and their agonists and antagonists involved - LXR, PPAR, ABCA1, apoE, oxysterols, cholesterol metabolites etc. The writer then discusses how they all work together to transport cholesterol from the arterial walls in order to minimize atherosclerosis.

From the Paper:

"Atherosclerosis is a form of arteriosclerosis in which plaque builds up in the inner linings of the arteries. Plaque consists of a combination of fatty substances, cholesterol waste products from cells fibrin and calcium and usually develops in medium and large arteries, thickening their walls and causing them to lose elasticity and so become less resilient. Atheromatous plaques build up in vessel walls and in advanced stages reduce or restrict blood flow through the vessel lumen. The inner covering of the atheroma may ... "
