Intracellular proton extrusion in gastric cancer cells has been reported to promote cancer cell survival under acidic conditions via hydrogen/potassium adenosine triphosphatase (H+/K+-ATPase). Rabeprazole is a frequently used second-generation proton pump inhibitor (PPI) that irreversibly inactivates gastric H+/K+-ATPase. Therefore, we hypothesized that rabeprazole could reduce the viability of...
The inhibition effects of tea theaflavins complex (TFs), theaflavin-3-3'-digallate (TFDG), theaflavin-3'-gallate (TF2B), and an unidentified compound (UC) on the growth of human liver cancer BEL-7402 cells, gastric cancer MKN-28 cells and acute promyelocytic leukemia LH-60 cells were investigated. TFs was obtained through the catalysis of catechins with immobilized polyphenols oxidase. TFDG, TF...
The chemokine receptor CXCR4 is associated with the biological behavior of cancer, but few studies have addressed the expression and function of CXCR4 in human gastric cancer and its impact on disease prognosis. We studied the expression of CXCR4 using RT-PCR, Western blotting, flow cytometry, and confocal microscopy in five gastric cancer cell lines. We also examined cell proliferation, migrat...
PURPOSE Dopamine and cAMP-regulated phosphoprotein, Mr 32,000 (DARPP-32), is overexpressed during the gastric carcinogenesis cascade. Here, we investigated the role of DARPP-32 in promoting resistance to treatment with TRAIL. EXPERIMENTAL DESIGN In vitro cell models including stable expression and knockdown of DARPP-32 were used. The role of DARPP-32 in regulating TRAIL-dependent apoptosis wa...
OBJECTIVE Accumulating evidences suggest that cancer-associated fibroblasts are provided from bone-marrow-derived mesenchymal stem cells (BM-MSCs); however, little is known about the mechanism(s) by which BM-MSCs accelerate cancer aggressiveness. METHODS Gastric carcinoma (GC)-derived MKN-7 cells were cocultured with UE6E7T-12 BM-MSCs. The gene expression profile in MKN-7 cells was investigat...
