BACKGROUND The risk of chronic obstructive pulmonary disease (COPD) is related to Gc protein allele type, such as Gc*1F, Gc*IS, Gc*2. It has been reported that Gc*1F increased COPD risk, while Gc*2 suppressed the risk. Thus, the allele type of Gc protein is an important factor in COPD. These Gc proteins differ in sugar composition at Thr418 or Thr420. In this study, features of the sugar struct...

BACKGROUND Gastric premalignant conditions, atrophic gastritis (AG) and intestinal metaplasia (IM) are characterized by an increase of proliferation and a reduction of apoptosis in epithelial cells. The epithelial cell kinetics in AG and IM in gastric mucosa adjacent to gastric cancer is still unclear. The aim of this study was to evaluate the epithelial cell turnover and expression of prolifer...

BACKGROUND MicroRNAs (miRNAs) are widely studied non-coding RNAs that modulate gene expression. MiRNAs are deregulated in different tumors including gastric cancer (GC) and have potential diagnostic and prognostic implications. The aim of our study was to determine miRNA profile in GC tissues, followed by evaluation of deregulated miRNAs in plasma of GC patients. Using available databases and b...

PURPOSE Goblet cells may represent a potentially successful adaptive response to acid and bile by producing a thick mucous barrier that protects against cancer development in Barrett's esophagus (BE). The aim of this study was to determine the relationship between goblet cells (GC) and risk of progression to adenocarcinoma, and DNA content flow cytometric abnormalities, in BE patients. EXPERI...

BACKGROUND We compared relapse-free survival (RFS) in gastric neuroendocrine carcinoma (WHO grade 3) and gastric carcinoma (GC). This is one of very few studies that compare the prognosis of poorly differentiated neuroendocrine carcinoma (WHO grade 3, G3 NEC) with that of GC. METHODS Between 1996 and 2014, 63 patients were diagnosed with G3 NEC of the stomach and 56 with gastric neuroendocrin...

AIMS Metallothionein 2A (MT2A) and nuclear factor-kappaB (NF-κB) are both involved in carcinogenesis and cancer chemosensitivity. We previously showed decreased expression of MT2A and IκB-α in human gastric cancer (GC) associated with poor prognosis of GC patients. The present study investigated the effect of diallyl trisulfide (DATS), a garlic-derived compound, and docetaxel (DOC) on regulatio...

Helicobacter pylori is an important risk factor of gastric cancer (GC). Although many H. pylori virulence factors have been reported, the pathogenic mechanism by which H. pylori infection causes GC remains unclear. The aims of this study were to identify GC-related antigens from H. pylori and characterize their roles in the development of GC. As GC and duodenal ulcer (DU) are considered clinica...

Histone demethylase plant homeodomain (PHD) finger protein 8 (PHF8) has been implicated in tumor development and malignant progression in various types of cancers. However, its potential roles in gastric cancer (GC) have not been explored. In this report, we show that PHF8 expression is upregulated in GC tissues, and the enhanced PHF8 level indicates a poor prognosis of GC patients. PHF8 knockd...

INTRODUCTION The mechanism underlying the spontaneous improvement of rheumatoid arthritis (RA) during pregnancy and the subsequent postpartum flare is incompletely understood, and the disease course varies widely between pregnant RA patients. In pregnancy, total and free levels of cortisol increase gradually, followed by a postpartum decrease to prepregnancy values. The glucocorticoid receptor ...

a total of 781 serum and 827 red cell samples from four populations of iran (kashan, ardestan, asrara and ardabil) were sub-typed by isoelectric focusing for group-specific componet and red cell enzyme phosphoglucomutase, locus one, respectively. heterogeneity test revealed no significant differences among the populations studied regarding both pgm1 and gc systems.
