Matrix control of transforming growth factor- function

Tumor-suppressive and promoting function of transforming growth factor beta.

Transforming growth factor beta (TGFbeta) is a multifunctional polypeptide. Its role in carcinogenesis can be either suppressive or promoting depending on tumor developmental stages and cellular context. During the early phase of epithelial tumorigenesis, TGFbeta inhibits primary tumor development and growth by inducing cell cycle arrest and possibly apoptosis. However, in late stages of progre...

Transforming growth factor-β

Dna2 was first characterized in yeast as an essential gene encoding a protein with both helicase and endonuclease activities involved in maturation of Okazaki fragments during DNA replication. Dna2 also plays a role in double-strand break (DSB) repair by homolo-gous recombination. The respective contributions of its replication and/or repair functions toward cell viability and resistance to gen...

Effect of Transforming Growth Factor-β (TGF-β) on proliferation of gastric epithelial cells in culture

Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...

Transforming growth factor signal transduction

Transforming growth factor beta1 (TGF1) is the prototypic member of a large family of structurally related pleiotropic-secreted cytokines that play a pivotal role in the control of differentiation, proliferation, and state of activation of many different cell types including immune cells. TGFfamily members have potent immunosuppressor activities in vitro and in vivo. These cytokines trigger the...
