Association of variants in renal salt reabsorption-related gene SLC12A3 with essential hypertension in a Mongolian population

J. Q. Liang, Xi, Y. G., An, C. Y., and Su, X. L., Association of variants in renal salt reabsorption-related gene SLC12A3 with essential hypertension in a Mongolian population, vol. 14, pp. 10026-10036, 2015.

Mounting evidence has implicated the SLC12A3 gene in essential hypertension. Here, we examined the potential associations of common variants of the SLC12A3 gene with blood pressure traits in Mongolians in China. Genomic DNA was extracted from 508 unrelated Mongolian patients with essential hypertension and 246 normotensive Mongolian subjects for genotyping. The genotype distributions of all selected polymorphisms were consistent with Hardy-Weinberg equilibrium.

Hypertension-mediated enhancement of JNK activation in association with endoplasmic reticulum stress in rat model hippocampus with cerebral ischemia-reperfusion

Y. N. Zhao, Li, J. M., Chen, C. X., Zhang, P., and Li, S. X., Hypertension-mediated enhancement of JNK activation in association with endoplasmic reticulum stress in rat model hippocampus with cerebral ischemia-reperfusion, vol. 14, pp. 10980-10990, 2015.

Acute brain ischemia can induce the activation of c-Jun N-terminal kinases (JNKs). Hypertension is a critical etiology for brain ischemia. We identified the effects of hypertension on the activation of JNK as well as its impact on SP600125, a JNK inhibitor, during endoplasmic reticulum stress (ERS) in the hippocampus using a rat model. Transient whole-brain ischemia was induced by 4-vessel occlusion (bilateral vertebral and bilateral common carotid arteries) in normal and spontaneous hypertensive rats. SP600125 (0.05 mg/kg, iv) was administered 30 min before ischemia.

Relationship between carotid artery atherosclerosis and sulfatide in hypertensive patients

G. Li, Hu, R., Gu, J., and Wu, H. - Z., Relationship between carotid artery atherosclerosis and sulfatide in hypertensive patients, vol. 14, pp. 4840-4846, 2015.

Hypertension is a major traditional risk factor for atherosclerosis, and carotid artery intima-media thickness (IMT) is considered to be an important marker of atherosclerosis. Sulfatides have been shown to play a role in atherogenesis and vascular inflammation, resulting in atherosclerosis. This study aimed to assess the association between serum sulfatide and carotid artery IMT among hypertensive patients. We chose 60 hypertensive patients and 30 matched healthy controls. All subjects had medical examinations at Hebei General Hospital between March 2011 and March 2012.

Association of a CYP4A11 polymorphism and hypertension in the Mongolian and Han populations of China

J. Q. Liang, Yan, M. R., Yang, L., Suyila, Q., Cui, H. W., and Su, X. L., Association of a CYP4A11 polymorphism and hypertension in the Mongolian and Han populations of China, vol. 13, pp. 508-517, 2014.

Human cytochrome P450 4A11 (CYP4A11) plays a role in the regulation of blood pressure through the conversion of arachidonic acid into 20-hydroxyeicosatetraenoic acid (20-HETE). We therefore investigated the association between a CYP4A11 polymorphism (rs9333025) with hypertension in the Mongolian and Han ethnic groups. We studied 514 Mongolians in a pastoral area, including 201 hypertension patients and 313 normotensive controls, and 524 Han individuals in an urban area, including 215 hypertension patients and 309 normotensive controls.

Association of beta 2 adrenoceptor gene polymorphisms in Malaysian hypertensive subjects

M. Komara, Vasudevan, R., Ismail, P., Bakar, S. A., Pishva, S. R., and Heidari, F., Association of beta 2 adrenoceptor gene polymorphisms in Malaysian hypertensive subjects, vol. 13, pp. 2939-2948, 2014.

The sympathetic nervous system plays a major role in blood pressure regulation. Beta 2 (β2) adrenoceptor gene polymorphisms have been associated with hypertension in different populations with conflicting results. We examined the association of three common polymorphisms, Arg16Gly, Gln27Glu, and Thr164Ile, of the β2 adrenoceptor gene in Malaysian hypertensive subjects. A total of 160 hypertensive and control subjects were recruited. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and anthropometric measurements were obtained from each subject.

Significant association between lower pulse pressure and increasing levels of a novel type of phospholipid

C. S. Yao, Wu, Q. Z., Xu, H. X., Liu, F., Chang, L. G., Song, L. C., Gao, L. S., and Meng, X. L., Significant association between lower pulse pressure and increasing levels of a novel type of phospholipid, vol. 13, pp. 2922-2930, 2014.

The aim of this study was to analyze the association between pulse pressure and a novel type of phospholipid with solubility similar to that of lysophosphatidic acid (LPA), designated as AP, which was reported to be elevated during ischemia. In this cross-sectional study, 416 hypertensive patients and 252 controls aged between 35 and 70 years were enrolled consecutively. Fasting blood samples were extracted for assays of phospholipids and other biomarkers. Compared to controls, the hypertensive patients had higher levels of both LPA [odds ratio (OR) = 3.83] and AP (OR = 4.30).

Serum levels of high-sensitivity troponin T: a novel marker for left ventricular remodeling and performance in hypertensive subjects

D. M. Miao, Zhang, L. P., Yu, H. P., Zhang, J. Y., Xiao, W. K., and Ye, P., Serum levels of high-sensitivity troponin T: a novel marker for left ventricular remodeling and performance in hypertensive subjects, vol. 13, pp. 5143-5153, 2014.

It has been well established that high-sensitivity cardiac troponin T (hs-TnT) is a specific and highly sensitive marker in acute coronary syndromes. On the other hand, studies on serum concentrations of hs-TnT in patients with hypertension in the absence of significant coronary stenosis are limited. Therefore, we hypothesized that hs-TnT levels are related to left ventricular (LV) remodeling and performance in hypertension. We included 537 hemodynamically stable hypertensive subjects, 247 males aged 60.7 ± 11.1 years, and 100 normotensive subjects of similar age and gender.

RT-qPCR assay on the vitamin D receptor gene in type 2 diabetes and hypertension patients in Turkey

H. C. Vural and Maltas, E., RT-qPCR assay on the vitamin D receptor gene in type 2 diabetes and hypertension patients in Turkey, vol. 11, pp. 582-590, 2012.

RT-qPCR was used to analyze the vitamin D receptor (VDR) gene TaqI polymorphism in 100 Turkish patients with type 2 diabetes mellitus (T2DM) and hypertension compared with 100 healthy subjects, to determine whether VDR could be considered as one of the susceptibility genes for T2DM and hypertension. Genotyping was done with PCR, followed by melting curve analysis with specific fluorescent hybridization probes. The results showed that distributions for TT, Tt and tt genotypes were 51, 46 and 3% in the patient group, and 35, 49 and 16% in the control group, respectively.

Genetic variations in MOV10 and CACNB2 are associated with hypertension in a Chinese Han population

G. L. Hong, Chen, X. Z., Liu, Y., Liu, Y. H., Fu, X., Lin, S. B., and Zhu, Q., Genetic variations in MOV10 and CACNB2 are associated with hypertension in a Chinese Han population, vol. 12, pp. 6220-6227, 2013.

Human hypertension is a complex, multifactorial disease. Multiple variants associated with hypertension have been identified in the large numbers of genome-wide association studies, meta-analysis, and case-control studies. The present study investigated the association between the single nucleotide polymorphisms (SNPs) of five candidate genes and the susceptibility and prognosis of hypertension in a Chinese Han population. A hospital-based case-control study in a Chinese Han population was carried out, including 500 hypertension patients and 506 healthy controls.

Association between peroxisome proliferator-activated receptor gamma coactivator-1 alpha polymorphism and hypertension in Mongolians in Inner Mongolia

X. L. Su, Dong, H. R., Yan, M. R., Cui, H. W., Yang, L., and Han, F. Q., Association between peroxisome proliferator-activated receptor gamma coactivator-1 alpha polymorphism and hypertension in Mongolians in Inner Mongolia, vol. 10, pp. 3930-3936, 2011.

We investigated a possible association of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) Gly482Ser polymorphism with hypertension in Mongolians in Inner Mongolia. A total of 787 subjects were enrolled randomly, including 390 hypertension patients and 397 healthy controls. Triglycerides, cholesterol, and fasting plasma glucose were measured, and body mass index was calculated. PCR-RFLP was used to analyze Gly482Ser polymorphisms.
