Association study of angiotensin II type 1 receptor: A1166C (rs5186) polymorphism with coronary heart disease using
Unlabelled:
Angiotensin II type 1 receptor (AT1R) mediates the cardiovascular actions of angiotensin II. Growing studies have revealed the underlying association between AT1R-A1166C (rs5186) polymorphism and coronary heart disease (CHD) among the East Asia population.
Results:
from these studies remain conflicting. We conducted this meta-analysis to estimate the overall CHD risk of AT1R-A1166C polymorphism regarding the East Asia population. We searched the PubMed, Embase and China National Knowledge Infrastructure (CNKI) databases for all articles within a range of published years from 1995 to 2011. The odds ratio (OR) corresponding to the 95% confidence interval (CI) was used to assess the different associations. The statistical heterogeneity among studies was assessed with the Q-test and I (2) statistics. Up to December 2011, 17 case-control studies, including 2,366 cases and 2,414 controls, were available for our study. The C allele and the AC/CC genotypes were associated with significantly increased risk of CHD (OR = 1.59, 95% CI = 1.22-2.06 for C versus A and OR = 1.57, 95% CI = 1.16-2.13 for AC/CC versus AA, respectively). Our result suggested that AT1R-A1166C polymorphism may be involved in the development of CHD.

Adrenergic Receptors: ɑ Subtype
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...
Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...
