miR-126 is an endothelial-specific microRNA essential for governing vascular integrity and angiogenesis. Its role in tumor angiogenesis of gastric cancer (GC) is unclear. This study aimed at determining the role of miR-126 in GC angiogenesis. Down-regulation of miR-126 was found to inversely correlate with an increased microvessel density (MVD) and vascular endothelial growth factor A (VEGF-A) ...

one of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. one of the most described cellular defense mechanisms involved in resistance is glutathione (gsh) and in this study, the effects of cisplatin on the total intracellular gsh level (gshi) in some sensit...

ERC/mesothelin is expressed in mesothelioma and other malignancies. The ERC/mesothelin gene (MSLN) encodes a 71-kDa precursor protein, which is cleaved to yield 31-kDa N-terminal (N-ERC/mesothelin) and 40-kDa C-terminal (C-ERC/mesothelin) proteins. N-ERC/mesothelin is a soluble protein and has been reported to be a diagnostic serum marker of mesothelioma and ovarian cancer. Gastric cancer tissu...

Abstract Background Gastric cancer (GC) remains an important worldwide. Further understanding of the molecular mechanisms gastric carcinogenesis will enhance diagnosis and treatment GC. Methods The expression DLEU2 ETS2 was analyzed in several GC cell lines using GEPIA online analyze, qRT-PCR immunohistochemistry. biological behavior cells detected by CCK8, clone formation, transwell, wound hea...

Helicobacter pylori (H. pylori) can infect into the epithelial cell to cause benign or malignant disorders. Under stressful environment, a spiral form of H. pylori is transformed into a coccoid form. The infectivity of the coccoid form is still controversial. Since spiral forms are transformed into two types of coccoid forms via different mechanisms, the infectivity of the two types of coccoid ...

objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...

Purpose: Despite the high prevalence of gastric cancer (GC), drug resistance is a major problem for effective chemotherapy. B7-H7 novel member B7 superfamily and expressed in most common cancers. However, role on aggressiveness GC chemosensitivity has remained unknown. Therefore, this study was designed to assess effect suppression using small interference RNA (siRNA) combination with docetaxel...
