essential hypertension/proline

OBJECTIVE Despite the claimed disregulation of extracellular matrix synthesis and the increased proliferation rate of different cell types in experimental models of hypertension, very few data are available on collagen synthesis and the proliferation rate of fibroblasts in essential hypertensive

Liddle's syndrome is a rare monogenic form of hypertension caused by truncating or missense mutations in the C termini of the epithelial sodium channel beta- or gamma-subunits. These mutations delete or alter a conserved proline-rich amino acid sequence referred to as the PY-motif. We report here a

The antihypertensive efficacy of N-[(S)-1-(ethoxycarbonyl)-3-phenyl-propyl]-L-alanyl-L-proline (enalapril maleate) was evaluated in a randomized, double-blind trial in 23 patients with mild low-renin essential hypertension ranging in age from 32 to 70 yr (20 were black and 3 were white). All

OBJECTIVE The gamma subunit of the epithelial Na channel (gammaENaC) has been implicated in Liddle's syndrome. The objective of this study was to examine its status in essential hypertension. METHODS The search for molecular variants was performed using the SSCP technique after determination of the

Evidence is mounting that a multi-gene kinase network is central to the regulation of renal Na(+) and K(+) excretion and that aberrant signaling through the pathway can result in renal sodium retention and hypertension (HTN). The kinase network minimally includes the Ste20-related

Previous genome-wide association studies identified serine threonine kinase 39 (STK39), encoding STE20/SPS1-related proline/alanine-rich kinase, as one of a limited number of hypertension susceptibility genes. A recent meta-analysis confirmed the association of STK39 intronic polymorphism rs3754777

Epithelial Na(+) channels (ENaC) mediate the transport of sodium (Na) across epithelia in the kidney, gut, and lungs and are required for blood pressure regulation. They are inhibited by ubiquitin protein ligases, such as Nedd4 and Nedd4-2, which bind to proline-rich motifs (PY motifs) present in

OBJECTIVE Studies of inherited conditions characterized by high or low blood pressure reveal the importance of a new signalling cascade, With no Lysine kinases (WNK) --> ste20/SPS1-related proline/alanine-rich kinase (SPAK)/oxidative stress-responsive kinase-1 (OSR1) --> Cation-Chloride

Delapril, a nonsulfhydryl angiotensin converting enzyme (ACE) inhibitor, which has an indanylglycine moiety differing from the proline moiety of captopril or enalapril, is an esterified prodrug that is converted in vivo to its active metabolites. Delapril effectively inhibits rabbit lung ACE

BACKGROUND Epithelial Na(+) channels (ENaC) mediate the transport of sodium (Na) across epithelia in the kidney, gut and lungs and are required for blood pressure regulation. They are inhibited by ubiquitin protein ligases, such as Nedd4-2. These ligases bind to proline-rich motifs (PY motifs)

Gain-of-function mutations in the human WNK1 (with-no-lysine[K]1) gene are responsible for a monogenic form of arterial hypertension, and WNK1 polymorphisms have been associated with common essential hypertension. The role of WNK1 in renal ionic reabsorption has been established, but no

Major advances are being made in identifying the structure and behaviour of regulatory cascades that control the activity of cation-Cl(-) cotransporters and certain Na(+), K(+) and Cl(-) channels. These transporters play key roles in regulating arterial blood pressure as they are not only

OBJECTIVE The discovery of causative genes leading to hypertension in animal models can reveal new mechanistic insights into blood pressure (BP) regulations. Previously, we isolated segments that harbor BP quantitative trait loci (QTLs) on rat chromosome 10 as defined by congenic strains made from

The mammalian SPS1-related proline/alanine-rich serine-threonine kinase SPAK (STK39) modulates ion transport across and between epithelial cells in response to environmental stimuli such osmotic stress and inflammation. Research over the last decade has established a central role for SPAK in the

The WNK-SPAK/OSR1 kinase complex is composed of the kinases WNK (with no lysine) and SPAK (SPS1-related proline/alanine-rich kinase) or the SPAK homolog OSR1 (oxidative stress-responsive kinase 1). The WNK family senses changes in intracellular Cl(-) concentration, extracellular osmolarity, and cell
