Summary

The apelin-APJ signaling pathway has emerged as an important novel mediator of cardiovascular control and blood pressure homeostasis. Genetic variation in apelin and its receptors likely contributes to essential hypertension, in addition to a range of traditional risk factors. Thus, a study will be conducted on Syrian patients with hypertension and coronary artery disease to investigate some of the single polymorphisms in the apelin gene and its receptor that may be responsible for the development of these diseases, and to link the levels of this peptide and its receptor in the blood with these polymorphisms and the percentage of these diseases (as shown by many Modern Global Reference Studies).

Detailed description

Blood levels of apelin and its receptor will be determined in patients and controls, and correlated with hypertension and coronary artery disease. And the allelic and genotypic frequencies of the G212A single polymorphism nucleotide of the apelin receptor gene and the -1860T\>C single polymorphism nucleotide of the apelin gene in the study groups. And evaluation the functional role of A allele in hypertension. As well as investigating the association between: the genotypes of the apelin gene and the levels of apelin in the plasma, the genotypes of the apelin receptor gene and the levels of APJ in the plasma in the study groups. And link the polymorphism of the apelin gene with the polymorphism of the apelin receptor gene. And to determine the correlation between the presence of the studied SNPs and some traditional risk factors for coronary artery disease, which are age, hypertension, the onset age of hypertension, smoking, BMI, cholesterol and triglyceride levels in the blood, and family history of CAD.
