Evaluation of Apoptotic Effect Protein Fusion, Enterocin A, R-Type Pyocin, Lactocin, and Specific Ligand on Gastric Cancer Cell Line (AGS)

Opuntia humifusa (OHF) has been used as a nutraceutical source for the prevention of chronic diseases. In the present study, the inhibitory effects of ethyl acetate extracts of OHF on the proliferation of AGS human gastric cancer cells and the mode of action were investigated. To elucidate the antiproliferative mechanisms of OHF in cancer cells, the expression of genes related to apoptosis and ...

Histamine is a biogenic amine, which is involved in a variety of biologic processes comprising inflammation, allergic responses, neurotransmission and regulation of gastric acid secretion. The key enzyme for the generation of histamine is histidine decarboxylase (HDC), which converts the amino acid L-histidine to histamine. In this article, we review the history, biochemistry and molecular biol...

Objective: Dorema glabrum Fisch. & C.A. Mey is a perennial plant that has several curative properties. Anti-proliferative activity of seeds of this plant has been demonstrated in a mouse fibrosarcoma cell line. The aim of the present study was to evaluate cytotoxicity of D. glabrum root extracts in a human gastric adenocarcinoma (AGS) cell line and explore mechanisms of apoptosis induction, cel...

Background & Objective: Gastric cancer is the second most frequent cause of cancer death worldwide, despite differences in incidence around the world. The majority of gastric cancer cases concern gastric adenocarcinoma, which has a fairly high 5-year survival rate when coupled with early-stage diagnosis. Versican, a member of the aggregating chondroitin sulfate proteoglycans fa...

cancer starts with a change in one single cell. this change may be initiated by external agents and genetic factors. cancer is a leading cause of death worldwide and accounts for 7.6 million deaths (around 13% of all deaths) in 2008. lung, stomach, liver, colon and breast cancer cause the most cancer deaths each year. in this review, different aspects of gastric cancer; including clinical, path...

Eudesmin has been proven to possess anti-inflammatory effects. In the present study, the effects of eudesmin on Helicobacter pylori (H. pylori)-mediated autophagy, apoptosis, immune response and inflammation were determined in human gastric adenocarcinoma (AGS) cells in vitro and in C57BL/6 mice in vivo. Detection of the production of interleukin (IL)-8, IL-1β and immunoglobulin M (IgM) was per...

BACKGROUND Helicobacter pylori (HP) infection induces methylation silencing of specific genes in gastric epithelium. Various stimuli activate the nonselective cation channel TRPV4, which is expressed in gastric epithelium where it detects mechanical stimuli and promotes ATP release. As CpG islands in TRPV4 are methylated in HP-infected gastric epithelium, we evaluated HP infection-dependent cha...

NF-κB pathway is a link between inflammation and cancer and is involved in cellular responses to different stimuli. Gastrointestinal lumen is exposed to many inflammatory agents such as foods, free radicals and bacterial or viral antigens. The aim of the present study was to evaluate the possible role of NF-κB1in gastric adenocarcinoma. To detect the relative level of NF-κB1transcript, total RN...
