STK39 was earlier implicated as a hypertension susceptibility gene and is thought to be involved in the control of Na-Cl co-transporter activity. STK39 has been implicated as a putative thiazide diuretic response gene, as Na-Cl co-transporter activity is inhibited by thiazides. Thus, we aimed to determine whether STK39 is a ...

The monk parakeet (Myiopsitta monachus) is a successful invasive species that does not exhibit life history traits typically associated with colonizing species (e.g., high reproductive rate or long-distance dispersal capacity). To investigate this apparent paradox, we examined individual and population genetic patterns of microsatellite loci at one native and two ...

BACKGROUND: HSD3B1 and HSD3B2 are crucial enzymes for the synthesis of hormonal steroids, including aldosterone. Therefore, HSD3B gene variations could possibly influence blood pressure (BP) by affecting the aldosterone level. METHODS: We performed a haplotype- and diplotype-based case-control study to investigate the association between the HSD3B gene variations and essential ...

Parasites and pathogens are possibly key evolutionary forces driving recognition systems. However, empirical evidence remains sparse. The ubiquitous pioneering ant Formica fusca is exploited by numerous socially parasitic ant species. We compared the chemical cue diversity, egg and nest mate recognition abilities in two Finnish and two UK populations where ...

Association of the lipoprotein lipase (LPL) gene S447X variant with hypertension has been investigated extensively, whereas the results are often irreproducible. We therefore conducted a meta-analysis to examine whether S447X variant was associated with hypertension and blood pressure variation. Case-control reports published in English language and humans were identified from ...

African American women have the highest prevalence of hypertension and obesity of any group in the United States. African American girls have the highest incidence of obesity of any groups of children in the nation, and diagnoses of hypertension have been rising among this group. Because both genetic heredity and ...

Hypertension is a condition with major cardiovascular and renal complications, affecting nearly a billion patients worldwide. Few validated gene targets are available for pharmacological intervention, so there is a need to identify new biological pathways regulating blood pressure and containing novel targets for treatment. The genetically hypertensive "blood pressure high" ...

Regional infusions of beta(2)-adrenoceptor (ADRB2) agonist have generally shown that individuals homozygous for Gly16 produces greater vasodilatation than those homozygous for Arg16. Systemic infusions have shown an opposite effect on systemic vascular resistance (SVR), possibly confounded by baroreflexes or interactions between single nucleotide polymorphism (SNP) positions 16 and 27. We ...

To clarify whether reduced cholesteryl ester transfer protein (CETP) activity carries inherent blood pressure risks and to infer whether the increased blood pressure and elevated mortality associated with torcetrapib are idiosyncratic or characteristic of this class of drugs. We examined the associations among CETP genotype, phenotype, and blood pressure in ...

The nicotinamide adenine dinucleotide phosphate (NADPH) oxidase produces superoxide, thus regulating redox state in the vessel wall. Three single-nucleotide polymorphisms (SNPs; -930A/G, A640G and C242T) of the p22(phox) subunit have been associated with hypertension; however, their role in peripheral and central pressures in normotensive individuals has not been addressed. A ...

The development of essential hypertension (EH) and inter-individual differences in response to antihypertensive treatment may partly result from genetic heterogeneity. In this study, we conducted an investigation of the combined effects of 5, 10-methylenetetrahydrofolate reductase (MTHFR) C677T and methionine synthase (MS) A2756G polymorphisms on baseline blood pressure (BP) and BP ...

IMPORTANCE OF THE FIELD: Only 23 - 41% of hypertensive patients receiving antihypertensive drugs achieve adequate blood pressure control. Multiple physiological systems regulate blood pressure and variation in genes involved in these systems may account for enhanced or diminished blood pressure lowering response to antihypertensive therapy. AREAS COVERED IN THIS ...

Several studies hinted about the clustering of risk variables of the metabolic syndrome (MS) and suggested that the underlying genetic polymorphisms could be responsible for the increasing incidence of coronary heart disease (CHD) in people of Indian origin. Therefore, identification of the components of the MS along with the genetic ...

In the marine littoral, strong grazing pressure selects for macroalgal defenses such as the constitutive and inductive production of defense metabolites. Induced defenses are expected under spatiotemporally varying grazing pressure and should be triggered by a reliable cue from herbivory, thereby reducing grazing pressure via decreased herbivore preference and/or performance. ...

Many species are habitat specialists along environmental gradients as a result of contrasting selection pressures, but others maintain broad distributions along such gradients. Phenotypic plasticity explains the persistence of some generalists, but not the broad distributions of species with fixed traits. We combined comparative and experimental data to investigate the ...

We examined the impact of hypertension on cerebrospinal fluid (CSF) biomarkers amyloid-beta1-42 (Abeta42), total tau (tau), and phosphorylated tau at threonine 181 (ptau-181), and assessed the modifying role of APOE genotype in this relation in 546 patients (mean age 65 +/- 10, 47% female) from our memory-clinic. Of these patients ...

Altered glucose metabolism due to insulin resistance is a common feature of essential hypertension in humans and in animal models. Elevated endogenous aldehydes in genetic (spontaneously hypertensive rats) and acquired (fructose-induced hypertensive rats) models of essential hypertension may be due to increased production of the reactive aldehyde methylglyoxal, resulting from ...

Despite its significant genetic component, the study of hypertension by genome-wide association presents more challenges than other common complex diseases. Its high prevalence, heterogeneity, and somewhat unclear definition are the challenges that need to be overcome on one hand. On the other hand, there are issues of small effect sizes ...

Army ants are well known for their destructive raids of other ant colonies. Some known defensive strategies include nest evacuation, modification of nest architecture, blockade of nest entrances using rocks or debris, and direct combat outside the nest. Since army ants highly prefer Pheidole ants as prey in desert habitats, ...

Mice deficiency in regulator of G-protein signaling 2(RGS2) showed an evident hypertension phenotype. Here, we studied associations of genetic variations of RGS2 with essential hypertension in the Kazakh population. Two identified nonsynonymous mutations (K18N, Y178C) were not specific for hypertension. A significant association was observed between 1891-1892 TC insertion/deletion with ...

Hypertension is a common condition that is a well-described risk factor for the development of cerebrovascular disease, myocardial infarction and heart failure. Medical therapy for hypertension may not only prevent development of these potentially devastating illnesses but may be used to treat high blood pressure, which coexists with these conditions. ...

In humans, the kidneys regulate blood pressure by balancing sodium concentrations. Fine-tuning of renal sodium reabsorption and excretion depends on the epithelial sodium channel protein (ENaC: protein complex of SCNN1A, SCNN1B, and SCNN1G). The surface expression of ENaC components is directed by the ubiquitination of ENaC by NEDD4L, an ENaC-specific ...

Genetic variation is thought to contribute to the etiology of hypertension, and E-selectin is a candidate essential hypertension-associated gene. This study thus sought to investigate possible genetic associations between the T1880C, C602A and T1559C polymorphisms of E-selectin and essential hypertension. Hypertensive patients (n = 490) and healthy normotensive subjects (n ...
