In this review, the influence of epithelial cells detected in bone marrow of patients with carcinoma of the upper GI tract on prognosis is analyzed. Methodological variables affecting bone marrow sampling, immunocytochemical approaches, and phenotyping of epithelial cells were evaluated as well as the correlation to clinical factors. The detection of epithelial cells in bone marrow varies betwe...
Runx3/Pebp2alphaC null mouse gastric mucosa exhibits hyperplasias due to stimulated proliferation and suppressed apoptosis in epithelial cells, and the cells are resistant to growth-inhibitory and apoptosis-inducing action of TGF-beta, indicating that Runx3 is a major growth regulator of gastric epithelial cells. Between 45% and 60% of human gastric cancer cells do not significantly express RUN...
The stomach of pigs at slaughter age is often colonized by Helicobacter (H.) suis, which is also the most prevalent gastric non-H. pylori Helicobacter (NHPH) species in humans. It is associated with chronic gastritis, gastric ulceration and other gastric pathological changes in both hosts. Parietal cells are highly specialized, terminally differentiated epithelial cells responsible for gastric ...
Helicobacter pylori is a major etiological agent in gastroduodenal disorders. The adhesion of H. pylori to human gastric epithelial cells is the initial step of H. pylori infection. Inhibition of H. pylori adhesion is thus a therapeutic target in the prevention of H. pylori infection. Experiments were performed to evaluate the effect of rebamipide, a novel antiulcer agent, on H. pylori adhesion...
Helicobacter pylori (H. pylori) is an important risk factor for chronic gastritis, peptic ulcer, and gastric cancer. Proteinase-activated receptor 2 (PAR2), subgroup of G-protein coupled receptor family, is highly expressed in gastric cancer, and chronic expression of cyclooxygenase-2 (COX-2) plays an important role in H. pylori-associated gastric carcinogenesis and inflammation. We previously ...
The structural characterization and function of the stomach in the omnivore Pygocentrus nattereri were described using light and scanning electron microscopy. The sac-like stomach was morphologically divided into the cardiac and pyloric regions. The histological structure of the stomach consisted of four layers of the mucosa, submucosa, muscularis, and serosa. The superficial epithelium of the ...
Scutellarin Inhibits the Growth and EMT of Gastric Cancer Cells through Regulating PTEN/PI3K Pathway
Gastric cancer is one of the most common malignancies with a high mortality rate world. This study intends to make clear role and mechanism Scutellarin (Scu), flavonoid isolated from Erigeron breviscapus (Vant.) Hand.-Mazz, in regulating evolvement gastric cancer. We selected different doses Scu treat cells (MGC-803 AGS). Then, cell counting kit-8 (CCK8) assay was conducted verify proliferation...
Gastric cancer is becoming the 4th leading cause of cancer-associated death worldwide. The purpose this study was to investigate role RGS1 in gastric vitro and vivo. Proliferation, migration, invasion, colony formation NCIN87 cells drug-resistant (NCIN87-DR) were determined. Cell apoptosis cell cycle examined using a flow cytometry assay. gene knock-down vector (pLVshshRGS1) Xenograft tumor mou...
Chronic gastritis induced by Helicobacter pylori is a strong risk factor for the development of distal gastric adenocarcinoma. A specific host response to H. pylori that may contribute to gastric carcinogenesis is epithelial cell apoptosis. The aim of this study was to investigate the capacity of H. pylori vacuolating toxin (VacA) to induce gastric epithelial cell apoptosis. When cocultured wit...
