CD103 (αE integrin) is an important dendritic cell (DC) marker that characterizes functionally distinct DC subsets in mice and humans. However, the mechanism by which CD103 expression is regulated in human DCs and the role of CD103 for DC function are not very well understood. Here, we show that retinoic acid (RA) treatment of human monocyte-derived DCs (MoDCs) increased the ability of the DCs to synthesize RA and induced MoDC expression of CD103 and β7 at the mRNA and protein level. In contrast, RA was unable to induce the expression of CD103 in primary human DCs isolated from the gastric mucosa...

Food intake is regulated by vagal afferent signals from the stomach. Nesfatin-1 is an anorexigenic peptide produced within the gastrointestinal tract and has well defined central effects. We aimed to determine if nesfatin-1 can modulate gastric vagal afferent signals in the periphery and further whether this is altered in different nutritional states. Female C57BL/6J mice were fed either a standard laboratory diet (SLD) or a high fat diet (HFD) for 12 weeks or fasted overnight. Plasma nucleobindin-2 (NUCB2; nesfatin-1 precursor)/nesfatin-1 levels were assayed, the expression of NUCB2 in the gastric mucosa and adipose tissue was assessed using real-time quantitative reverse-transcription polymerase chain reaction...

A woman in her 70s was an outpatient at our hospital. Esophagogastroduodenoscopy revealed a slightly elevated lesion with erosion, 10mm in diameter, located at the greater curvature of the antrum. Helicobacter pylori testing yielded negative results, and there was no atrophy of the gastric mucosa. Biopsy revealed a well-differentiated tubular adenocarcinoma. Complete en bloc resection was performed via endoscopic submucosal dissection, in accordance with the current Japanese guidelines. The gastric adenocarcinoma of the fundic gland type and coexisting with a hyperplastic or fundic gland polyp was negative according to the histological examination...

A growing body of research suggests daily low-dose aspirin (ASA) reduces heart diseases and colorectal cancers. However, the major limitation to the use of aspirin is its side effect to cause ulceration and bleeding in the gastrointestinal tract. Preclinical studies have shown that ginger constituents ameliorate ASA-induced gastric ulceration. We here report the design and synthesis of a novel prodrug of aspirin, [6]-gingerol aspirinate (GAS). Our data show that GAS exerts enhanced anti-cancer properties in vitro and superior gastroprotective effects in mice...

Meckel's diverticulum is the most common congenital abnormality of the small intestine that results from incomplete closure of the vitelline (omphalo-mesenteric) duct. This true diverticulum, ~2 ft from the ileocecal valve commonly found on the anti-mesenteric border of the ileum, is benign and majority asymptomatic. Diagnosis challenges arise when it became inflamed or presented in following ways, for example, haemorrhage (caused by ectopic pepsin-and hydrochloric acid-secreting gastric mucosa), intestinal obstruction (secondary to intussusception or volvulus) or the presence of diverticulum in the hernia sac (Littre's hernia)...

In many gastric cancer patients, the disease is diagnosed in an advanced stage and therefore the mortality levels are high. Because there is a need to identify novel early diagnostic and prognostic biomarkers, we tested whether SIRT1 and STAT3 are good candidates. Towards this, we used patient tissues representing different stages of gastric cancer including gastric pre-cancerous lesions, early gastric cancer, and advanced gastric cancer, and probed SIRT1, STAT3 and phosphorylated STAT3 (pSTAT3) levels using immunohistochemistry...

Gastric sarcoidosis with noncaseating granuloma is rare. Although corticosteroid produces a dramatic clinical response, it is unknown whether azathioprine show efficacy in prednisolone-dependent cases. Here, we report a case of gastric sarcoidosis in a 25-year-old man with severe epigastlargia. Gastroendoscopy revealed multiple map-like ulcerations. Histological examination showed multiple noncaseating granulomatous lesions in gastric mucosa, which were incompatible with diagnoses of Crohn's disease or tuberculosis...

Helicobacter pylori colonizes the gastric mucosa in the human stomach and represents a major risk factor for peptic ulcer disease and gastric cancer. Here, we summarize our current knowledge of the complex impact of H. pylori on manipulating host signalling networks, that is, by the cag pathogenicity island (cagPAI)-encoded type IV secretion system (T4SS). We show that H. pylori infections reflect a paradigm for interspecies contact-dependent molecular communication, which includes the disruption of cell-cell junctions and cytoskeletal rearrangements, as well as proinflammatory, cell cycle-related, proliferative, antiapoptotic, and DNA damage responses...

BACKGROUND: Receptor for advanced glycation end-products (RAGE), a receptor for amyloids, is constitutively expressed in lungs and generally observed to be downregulated in lung cancer tissues. However, increasing levels of RAGE or serum amyloids is associated with poor outcome in lung cancer patients. We report a rare case of primary systemic amyloid light-chain (AL) amyloidosis in biopsy-proven multiple organs with early-stage non-small cell lung cancer (NSCLC) that displayed strong staining for RAGE in the tumour tissue...
