J., Roozafzoon, R., and Ismail, P., “Association between the C34T polymorphism of the AMPD1 gene and essential hypertension in Malaysian patients”, vol. 15, p. -, 2016.

The aim of this study was to determine whether C34T, a common polymorphism of the adenosine monophosphate deaminase 1 gene (AMPD1), is associated with essential hypertension (EH). We hypothesize that C34T is associated with the development of EH. A case-control design was used for this study. The DNA was extracted using a commercial kit from the whole blood of 200 patients with hypertension and 200 subjects without hypertension from selected Malaysian ethnicities (Malays, Chinese, and Indians).

Association of A-20C polymorphism in the angiotensinogen gene with essential hypertension: a meta-analysis

R. Zeng, Wang, Q. P., Fang, M. X., Zhuang, J., and Fan, R. X., “Association of A-20C polymorphism in the angiotensinogen gene with essential hypertension: a meta-analysis”, vol. 14, pp. 12984-12992, 2015.

The A-20C polymorphism in the angiotensinogen (AGT) gene has been associated with increased risk of essential hypertension in several studies; however, these studies gave inconsistent results. In this study, we performed a meta-analysis to assess the association between AGT A-20C polymorphism and essential hypertension. Published literature was retrieved from PubMed. Pooled odd’s ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effect models.

Association of NPRA and NPRC gene variants and hypertension in Mongolian population

P. Y. Chang, Liu, Z. Y., Qin, L., and Zhao, P., “Association of NPRA and NPRC gene variants and hypertension in Mongolian population”, vol. 14, pp. 18494-18502, 2015.

NPRA and NPRC are candidate susceptibility genes for essential hypertension (EH) and play a key role in the regulation of plasma levels and biological effects of natriuretic peptides. The aims of the present study were to find new genetic markers in the NPRA and NPRC genes and to assess relationships between variants and EH. A total of 797 unrelated Mongolian herdsmen were enrolled, including 389 EH patients and 408 normotensive controls. Genotyping was performed using the polymerase chain reaction/ligase detection reaction assay.

Association of SNPs in the PPARγ gene and hypertension in a Mongolian population

L. Yang, Tian, R. G., Chang, P. Y., Yan, M. R., and Su, X. L., “Association of SNPs in the PPARγ gene and hypertension in a Mongolian population”, vol. 14, pp. 19295-19308, 2015.

The association of single nucleotide polymorphisms (SNPs) in PPARγ with hypertension is controversial. The aim of the present study was to clarify the contributions of PPARγ genetic variants to hypertension through an association study. A total of 414 unrelated Mongolian herdsmen and 524 Han farmers were included in this study. Fourteen intronic SNPs were analyzed and genotyped using a polymerase chain reaction/ligase detection reaction assay.

Association of TNF-α G308A gene polymorphism in essential hypertensive patients without type 2 diabetes mellitus

N. Ghodsian, Akhlaghi, M., Ramachandran, V., Heidari, F., Haghvirdizadeh, P., Eshkoor, S. A., Etemad, A., Jamaluddin, J. A., and Ismail, P., “Association of TNF-α G308A gene polymorphism in essential hypertensive patients without type 2 diabetes mellitus”, vol. 14, pp. 18974-18979, 2015.

This study aims to investigate the effects of tumor necrosis factor alpha (TNF-α) G308A gene polymorphism on essential hypertension (EHT) with or without type 2 diabetes mellitus (T2DM). The project was conducted on buccal epithelial and blood cells for case and control patients, respectively. Epithelial cells were obtained from the inner part of the cheeks. Techniques including DNA extraction, polymerase chain reaction (PCR), and restriction fragment length polymorphism (RFLP) were utilized to assess biomarkers of DNA damage.

G501C polymorphism of the oxidized LDL receptor gene is associated with albuminuria in Chinese essential hypertension patients

X. W. Hou, Hu, Z. H., Cui, Y., Gao, W., Sun, S. P., and Wang, N. F., “G501C polymorphism of the oxidized LDL receptor gene is associated with albuminuria in Chinese essential hypertension patients”, vol. 10, pp. 2710-2717, 2011.

Albuminuria is an independent predictor of renal and cardiovascular complications in hypertensive subjects. We previously showed that lectin-like oxidized low-density lipoprotein receptor 1 (OLR-1) polymorphisms at G501C are associated with susceptibility to essential hypertension and serum C-reactive protein levels. We have now investigated a possible association between OLR-1 polymorphisms at G501C, genotyped by PCR-RFLP, and severity of albuminuria in 307 hypertensive Chinese subjects and 225 age- and gender-matched controls.
