Human telomeric G-quadruplex DNA structures are attractive anticancer drug targets, but the target's polymorphism complicates design: different ligands prefer folds, and very few complexes have been solved at high resolution. Here we report that Phen-DC3, one of most prominent in terms binding affinity selectivity, causes dTAGGG(TTAGGG)3 to completely change its fold KCl solution from a hybrid-...

BACKGROUND/OBJECTIVES Recent studies have reported an association of the angiotensin II type 2 receptor (AT2R) 3123Cytosine/Adenine (3123C/A) polymorphism with essential hypertension and cardiovascular diseases. The purpose of the study was to investigate whether the AT2R 3123C/A polymorphism affects blood pressure for free-living hypertensive men during a 5-month intervention period. SUBJECT...

fects. Co-expression of KCNE1 (D76N) or KCNE1 (D85N) increases the susceptibility to clarithromycin, a macrolide antibiotic, lowering the IC50 to 1/3–2/3, whereas that of KCNE1 (A8V) decreases the susceptibility, doubling the IC50.1 Coexpression of KCNE1 (A8V), KCNE1 (D76N), or KCNE1 (D85N) increases the susceptibility to cisapride, a gastric prokinetic drug, lowering the IC50 to 1/2.1 Co-expre...

The etiology of common idiopathic epileptic syndromes is genetically determined, but the complex pattern of inheritance suggests an epistatic interaction of several susceptibility genes. Mutations in over 70 genes now define biological pathways leading to rare monogenic forms of epilepsy in humans and animals. Recognizing the molecular basis of an ion-channel disease has provided new opportunit...

BACKGROUND Genetic determinants of blood pressure (BP) response to potassium, or potassium sensitivity, are largely unknown. We conducted a genome-wide linkage scan and positional candidate gene analysis to identify genetic determinants of potassium sensitivity. METHODS AND RESULTS A total of 1906 Han Chinese participants took part in a 7-day high-sodium diet followed by a 7-day high-sodium p...

Objective: Type 2 diabetes (T2DM) is a worldwide prevalent metabolic disorder and the cause of many morbidities and mortalities. KCNQ1 gene encodes α-subunit of voltage-gated potassium (K+) channel which plays a role in insulin secretion in the pancreas, thus its variants may confer susceptibility to diabetes. Recognition of genetic variants involved in T2DM could help the early diagnosis and p...
