4% of all cancers in the USA. The reason for the low incidence of small intestinal carcinogenesis remains obscure. The unique microenvironment has been proposed in a global sense to explain the decreased susceptibility, but no specific factors have been identified. Symptoms at presentation are non-specific, with malignant neoplasms more often presenting with GI symptoms. Adenocarcinoma (non-ampullary) is the most common primary malignant small bowel tumor in Western countries, accounting for 30–50% of all primary malignant small bowel tumors. The management of small bowel
tumors depends on the histological subtype, location, and whether the tumor is malignant or benign. Surgery is the mainstay of therapy Torin 1 in vivo for all small bowel tumors. The prognosis is poor with the 5-year survival rate between 20%
and 38%. “
“Background and Aim: Methyl or 1, N6-ethenoadenine base lesions are frequent and highly-mutagenic or -carcinogenic events in mammalian DNA. Human AlkB homologue-2 (hABH2), a homologue of the Escherichia LDE225 in vivo coli AlkB protein, has been found to be the principal dioxygenase for the repair of these lesions. Mounting evidence indicates that impaired DNA repair contributes to gastric cancer induction and progression. Whether hABH2 is involved in this malignancy is unknown. The present study was aimed to investigate the expression profile of hABH2 in gastric cancer and the effect of hABH2 on cancer cell growth. Methods: The expression of hABH2 in 35 pair-matched gastric neoplastic and adjacent non-neoplastic tissues, and in five gastric cancer cell lines, was examined by real-time polymerase chain reaction (PCR), immunohistochemistry, or Western blot. The cell growth was determined using cell-counting kit-8 assay. The apoptosis or cell-cycle analysis was determined using flow cytometry. Results: The hABH2 expression was downregulated in 68% (24/35) of primary gastric cancers, as determined by real-time PCR; the hABH2 expression was also substantially decreased in gastric cancer cell lines. Immunohistochemical
or Western blot analysis further confirmed the downregulation of hABH2 expression in gastric cancers. The overexpression of hABH2 significantly inhibited the proliferation of gastric cancer cells, and induced G1 arrest of the cell cycle, MCE公司 while hABH2 knockdown promoted cell growth and cell-cycle progression of gastric cancer cells. Conclusions: These results suggest that hABH2 is downregulated in a subset of gastric cancers, and might be involved in the molecular mechanism of gastric cancer through inhibiting the proliferation of gastric cancer cells. “
“Background and Aim: The purpose of the present study was to determine the effects of interleukin-37 (IL-37) on liver cells and on liver inflammation induced by hepatic ischemia/reperfusion (I/R). Methods: Mice were subjected to I/R.
