Gene expression in hypertensives and diabetics predisposing to atherosclerosis

Ruggiero Mango, Irene Marta Predazzi, Francesco Romeo, Giuseppe Novelli
Atherosclerosis is the first cause of death in industrialized countries. Together with traditional risk factors (male gender, hypercholesterolemia, hypertension, diabetes, smoking and age), non-traditional risk factors have also been described as predisposing to this disease. Among these, oxidized low density lipoproteins (OxLDL) have been described in correlation to many proatherogenic processes. Many of the effects of OxLDL are mediated by the lectin like oxidized low density lipoprotein receptor 1 (LOX-1), expressed on endothelial cells, macrophages, SMCs and platelets...

Coronary atherosclerosis (CAD), a chronic inflammatory disorder, arises when genetic susceptibility, intercurrent conditions such as diabetes and hypertension and environmental factors interact. Although CAD can remain stable for many years, thrombus formation at sites of plaque rupture may lead to unstable angina (UA) or myocardial infarction (MI). Already recognised as the central component of coronary thrombosis, platelets, through their interaction with monocytes and endothelial cells, may also be involved at the earliest stages of atheromatous plaque evolution...

Insulin resistance syndrome (also called syndrome X) includes obesity, diabetes, hypertension, and dyslipidemia and is a complex phenotype of metabolic abnormalities. The disorder poses a major public health problem by predisposing individuals to coronary heart disease and stroke, the leading causes of mortality in Western countries. Given that hypertension, diabetes, dyslipidemia, and obesity exhibit a substantial heritable component, it is postulated that certain genes may predispose some individuals to this cluster of cardiovascular risk factors...

Type 2 diabetes mellitus is a condition associated with an increased risk of coronary artery disease. This condition is currently reaching epidemic proportions in the Western world. Epidemiological studies have shown that insulin resistance and the constellation of metabolic alterations associated with type 2 diabetes mellitus such as dyslipidaemia, systemic hypertension, obesity and hypercoagulability, have an effect on the premature onset and severity of atherosclerosis. Albeit direct, the link between insulin resistance and atherogenesis is rather complex...

BACKGROUND: Fasting hyperinsulinemia (reflected by elevations in immunoreactive "insulin") is typical of patients with non-insulin-dependent diabetes mellitus (NIDDM) and is often associated with obesity and hypertension. The elevated concentrations detected are indicative not only of insulin but also of its immunologically cross-reactive precursors, including proinsulin. Fasting hyperinsulinemia appears to be associated with decreased fibrinolytic activity in blood, which results from increased activity of plasminogen activator inhibitor type-1 (PAI-1), a potential independent risk factor for coronary artery disease...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
