A Novel Mechanism for Regulating Transforming Growth Factor β (TGF-β) Signaling

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...

An engineered transforming growth factor β (TGF-β) monomer that functions as a dominant negative to block TGF-β signaling.

The transforming growth factor β isoforms, TGF-β1, -β2, and -β3, are small secreted homodimeric signaling proteins with essential roles in regulating the adaptive immune system and maintaining the extracellular matrix. However, dysregulation of the TGF-β pathway is responsible for promoting the progression of several human diseases, including cancer and fibrosis. Despite the known importance of...

Suppression of Latent Transforming Growth Factor (TGF)-β1 Restores Growth Inhibitory TGF-β Signaling through microRNAs

Cancer cells secreting excess latent TGF-β are often resistant to TGF-β induced growth inhibition. We observed that RNAi against TGF-β1 led to apoptotic death in such cell lines with features that were, paradoxically, reminiscent of TGF-β signaling activity and that included transiently enhanced SMAD2 and AKT phosphorylation. A comprehensive search in Hela cells for potential microRNA drivers o...
