IL-13 improves beta-cell survival and protects against IL-1beta-induced beta-cell death
OBJECTIVES IL-13 is a cytokine classically produced by anti-inflammatory T-helper-2 lymphocytes; it is decreased in the circulation of type 2 diabetic patients and impacts positively on liver and skeletal muscle. Although IL-13 can exert positive effects on beta-cell lines, its impact and mode of action on primary beta-cell function and survival remain largely unexplored. METHODS Beta-cells w...
متن کاملTransforming growth factor beta 1 induces apoptotic cell death in cultured human gastric carcinoma cells.
Transforming growth factor beta 1 (TGF-beta 1) is a potent growth inhibitor for many cell types, including tumor cells. We recently have reported the establishment and characterization of two human gastric scirrhous carcinoma cell lines, HSC-39 and HSC-43. Here we examined the effect of TGF-beta 1 on the growth of these lines as compared to five other human gastric adenocarcinoma cell lines. Pr...
متن کاملEffect of transforming growth factor beta on cell death of cultured rat hepatocytes.
We investigate mechanisms of regression of liver hyperplasia which occurs after induction of growth by hepatomitogens and their subsequent withdrawal. We hypothesized that transforming growth factor beta 1 (TGF-beta 1) might be involved in the control of regression. Therefore we studied the effect of this agent on DNA synthesis and death of hepatocytes cultured in vitro. Both the low basal rate...
متن کاملThe regulation of eIF4F during cell growth and cell death.
Much effort has been focused on questions concerning the highly regulated processes of cell growth, proliferation and programmed cell death (apoptosis). Hormones, growth factors and ligands exert pleiotypic effects through activation of specific cell-surface receptors, and via transmembrane signalling and activation of common protein kinase/phosphatase cascades inside the cell. These, in turn, ...
متن کاملProgrammed cell death protein-1/programmed cell death ligand-1 pathway inhibition and predictive biomarkers: understanding transforming growth factor-beta role.
A deeper understanding of the key role of the immune system in regulating tumor growth and progression has led to the development of a number of immunotherapies, including cancer vaccines and immune checkpoint inhibitors. Immune checkpoint inhibitors target molecular pathways involved in immunosuppression, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) and programmed cell death pr...
