Expression of ADAM33 Is a Novel Regulatory Mechanism in IL-18-Secreted Process in Gastric Cancer

Gastric Cancer Mechanism in IL-18-Secreted Process in Expression of ADAM33 Is a Novel Regulatory

The IL-18 antagonist IL-18-binding protein is produced in the human ovarian cancer microenvironment.

PURPOSE Interleukin (IL)-18 is an immune-enhancing cytokine, which induces IFN-γ production, T-helper 1 responses, and antitumor effects. In turn, IFN-γ stimulates IL-18-binding protein production, which blocks IL-18 activity. In view of the potential use of IL-18 in epithelial ovarian cancer (EOC) immunotherapy, here, we studied IL-18BP expression and its regulation by cytokines in EOC cells i...

Is Dietary Pattern Associated with Gastric Cancer Risk? A Case-control Study in Iran

Background: Diet is considered as an important contributor to the development of the cancers. In the present study, the association of dietary patterns with gastric cancer risk was studied. Methods: In the present case-control study, 192 newly diagnosed gastric cancer patients and 365 subjects as control group were included. The participants in each group underwent face-to-face interview. For ...

Bioactive IL-18 expression is up-regulated in Crohn's disease.

An imbalance of immunoregulatory factors is believed to contribute to uncontrolled mucosal Th1 cell activation in Crohn's disease (CD). IL-18, a macrophage-like cell-derived cytokine, is involved in Th1 clone development, and IFN-gamma production. Therefore, IL-18 expression was investigated in CD. Whole mucosal intestinal tissue and lamina propria mononuclear cells (LPMC) of 12 CD and 9 ulcera...

Peptide fragments of AMP-18, a novel secreted gastric antrum mucosal protein, are mitogenic and motogenic.

Antrum mucosal protein (AMP)-18 is a novel 18-kDa protein synthesized by cells of the gastric antrum mucosa. The protein is present in secretion granules of murine gastric antrum epithelial cells and is a component of canine antrum mucus, suggesting that it is secreted into the viscoelastic gel layer on the mucosal surface. Release of the protein appears to be regulated because forskolin decrea...
