Epithelial-mesenchymal transition (EMT) is associated with tumor malignancy. The hedgehog-EMT pathway is preferentially activated in diffuse-type gastric cancer (GC) compared with intestinal-type GC; however, histological typing is currently the only method for distinguishing these two major types of GC. We compared the gene expression profiles of 12 bone marrow-derived mesenchymal stem cell cu...

Cyclophilin A (CypA), a receptor for the immunosuppressive agent cyclosporin A, is a cis-trans-peptidyl-prolyl isomerase (PPIase). It accelerates the cis-trans isomerization of prolyl-peptide bonds. CypA binds and regulates the activity of a variety of proteins. Atrial natriuretic factor (ANF) and its receptor membrane-bound guanylate cyclase-A (GC-A) are involved in the regulation of blood pre...

Two distinct calcitonin (CT) receptor (CTR)-encoding cDNAs (designated GC-2 and GC-10) were cloned and characterized from giant cell tumor of bone (GCT). Both GC-2 and GC-10 differ structurally from the human ovarian cell CTR (o-hCTR) that we cloned previously, but differ from each other only by the presence (GC-10) or absence (GC-2) of a predicted 16-amino acid insert in the putative first int...

The majority of atmospheric measurements of volatile organic compounds (VOCs) are usually limited to a small range, either in volatility or time resolution. A combined heart-cut gas chromatography (GC) with comprehensive two-dimensional GC (GC×GC) instrument was developed, specifically to increase the number of VOCs analysed using a single instrument. The system uses valve based modulation and ...

BACKGROUND Guanylate Cyclase C (GC-C) is an apically-oriented transmembrane receptor that is expressed on epithelial cells of the intestine. Activation of GC-C by the endogenous ligands guanylin or uroguanylin elevates intracellular cGMP and is implicated in intestinal ion secretion, cell proliferation, apoptosis, intestinal barrier function, as well as the susceptibility of the intestine to in...

C-terminal binding protein-2 (CtBP2), a transcriptional corepressor, has been reported to correlate with tumorigenesis and progression and predict a poor prognosis in several human cancers. However, few studies on CtBP2 in gastric cancer (GC) have been performed. In this research, we evaluated the correlations between CtBP2 expression and the clinicopathological characteristics, as well as prog...

AIM To estimate the association of vascular endothelial growth factor A (VEGFA) +936C/T and -634G/C polymorphisms and gastric cancer (GC) risk, a meta-analysis was performed. A total of nine studies were identified with 2,281 GC cases and 2,820 controls. This meta-analysis indicated significant associations between the VEGFA -634G/C polymorphism and GC risk were found for GC versus GG (OR 1.21,...
