Knowledge of the molecular interactions of human proteins within tissues is important for identifying their tissue-specific roles and for shedding light on tissue phenotypes. However, many protein-protein interactions (PPIs) have no tissue-contexts. The TissueNet database bridges this gap by associating experimentally-identified PPIs with human tissues that were shown to express both pair-mates. Users can select a protein and a tissue, and obtain a network view of the query protein and its tissue-associated PPIs...

BACKGROUND AND AIMS: Proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) suppress gastric acid production, which may inhibit iron absorption. However, little data exist regarding whether these medications increase the risk of clinical iron deficiency. METHODS: A community-based case-control study evaluated the association between acid-suppressing medication use and the subsequent risk of iron deficiency. It contrasted 77,046 patients with new iron deficiency diagnoses (January, 1999-December, 2013), with 389,314 controls...

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common cause of infectious morbidity and mortality in the intensive care unit (ICU). The type of stress-ulcer prophylaxis (SUP) given to ventilated patients may, in part, be responsible. We observed an increase in VAP as ventilator bundle compliance increased and a decrease in VAP when bundle compliance decreased. We reasoned that SUP which raises gastric pH such as proton-pump inhibitors (PPIs) and histamine II (H2) receptor antagonists as opposed to SUP which does not raise pH such as sucralfate (S) may be responsible and also may alter the causative bacteria...

Most cellular functions involve proteins' features based on their physical interactions with other partner proteins. Sketching a map of protein-protein interactions (PPIs) is therefore an important inception step towards understanding the basics of cell functions. Several experimental techniques operating in vivo or in vitro have made significant contributions to screening a large number of protein interaction partners, especially high-throughput experimental methods. However, computational approaches for PPI predication supported by rapid accumulation of data generated from experimental techniques, 3D structure definitions, and genome sequencing have boosted the map sketching of PPIs...

OBJECTIVE: Gastroesophageal reflux disease (GERD) represents one of the most common gastrointestinal disorders, but is still a challenge to cure. Proton pump inhibitors (PPIs) are currently the GERD's standard treatment, although not successful in all patients; some concerns have been raised regarding their long term consumption. Recently, some studies showed the benefits of inspiratory muscle training in increasing the lower esophageal sphincter pressure in patients affected by GERD, thereby reducing their symptoms...

Oesophageal adenocarcinoma is strictly related to gastroesophageal reflux and cylindrical metaplasia of the epithelium of the distal esophagus (Barrett's esophagus) due to chronic inflammation. Worldwide incidence of oesophageal adenocarcinoma is rising despite the availability of precise international guidelines for the treatment of gastroesophageal reflux disease and the increasing use of proton-pump inhibitors (PPIs). While PPIs can control GERD symptoms in a significant amount of cases, still a large number of patients progress to Barrett's esophagus and adenocarcinoma...

OBJECTIVES: In recent years, polypropyleneimine (PPI) dendrimers have attracted great interest as non-viral gene delivery systems because of their attractive features including highly branched architecture with number of reactive end groups. However, without being structurally modified, they are not efficient gene carriers. In the present study, generation 2 and 3 (G2 and G3) of PPI dendrimers were conjugated with alkylcarboxylate groups as linker to enhance the transfection efficiency while maintaining their low cell toxicity...

Dietary selenium (Se) deficiency may influence the calcium (Ca) homeostasis in broilers. Our objective was to investigate the effects of Se deficiency on Ca regulation related genes' change in heart of broilers. In the present study, 1-day-old broilers were fed either a commercial diet (as control group) with 0.15 mg/kg Se or a Se-deficient diet (as L group) with 0.033 mg/kg Se for 35 days. We examined the mRNA expression levels of 15 Ca regulation related genes (ITPR 1, ITPR 2, ITPR3, RyR2, RyR3, SERCA1s, SLC8A1, PMCA1, CACNA1S, TRPC1, TRPC3, STIM1, ORAI1, CaLM and CRT) in the heart of broilers...

Hypomagnesemia is the most concerned side effect of proton pump inhibitors (PPIs) in chronic users. However, the mechanism of PPIs-induced systemic Mg(2+) deficit is currently unclear. The present study aimed to elucidate the direct effect of short-term and long-term PPIs administrations on whole body Mg(2+) homeostasis and duodenal Mg(2+) absorption in rats. Mg(2+) homeostasis was studied by determining the serum Mg(2+) level, urine and fecal Mg(2+) excretions, and bone and muscle Mg(2+) contents. Duodenal Mg(2+) absorption as well as paracellular charge selectivity were studied...

Gastroesophageal reflux disease (GERD) is a common disorder of the upper gastrointestinal tract which is typically characterized by heartburn and acid regurgitation. These symptoms are widespread in the community and range from 2.5% to more than 25%. Economic analyses showed an increase in direct and indirect costs related to the diagnosis, treatment and surveillance of GERD and its complications. The aim of this review is to provide current information regarding the natural history of GERD, taking into account the evolution of its definition and the worldwide gradual change of its epidemiology...

Protein surface mimetics achieve high affinity binding by exploiting a scaffold to project binding groups over a large area of solvent exposed protein surface to make multiple co-operative non-covalent interactions. Such recognition is a pre-requisite for competitive/ orthosteric inhibition of protein-protein interactions (PPIs). This paper describes biophysical and structural studies on ruthenium(II) tris(bipyridine) surface mimetics that recognize cytochrome (cyt) c and inhibit the cyt c/ cyt c peroxidase (CCP) PPI...

OBJECTIVES: Use of proton pump inhibitors (PPIs) is histologically associated with oxyntic gland dilatations. Two interesting mucosal changes are often detected endoscopically in patients who use PPIs: gastric cracked mucosa (GCM) and gastric cobblestone-like mucosa (GCSM). The aim of this study was to clarify the relationship between PPI use and these mucosal changes. METHODS: This was a single-center observational study. All successive subjects who underwent a routine esophagogastroduodenoscopy (EGD) between August and November 2014 in Hokkaido University Hospital were enrolled...

The scaffold protein Axin plays important roles in multiple signaling pathways through mediating the formation of different signaling complexes. Axin is best known for its role as a negative regulator in Wnt/β-catenin pathway. Aberrant activation of the key components in Wnt/β-catenin pathway including Axin has been linked to a variety of human cancers. Drugs developed for this pathway are far from satisfying largely due to the limited targets especially enzymesin this pathway. Almost all Axinsignal pathways depend on a number of protein-protein interactions (PPIs) for transmitting information, making PPIs attractive targets and probably a future direction for drug discovery...
