    News: TGF-beta

    Smoking Stokes Cells’ Cancer Capacity

    Friday, March 16th, 2012

    Smoking contributes to the vast majority (around 85 percent) of lung cancer cases. The TGF-beta signaling pathway – which regulates cell growth and proliferation – is altered in several cancer types, but little is known about how smoking affects this pathway. To investigate this, Debangshu Samanta, Pran Datta, Ph.D., and colleagues exposed human lung epithelial […]

    Colon Cancer’s Cellular Crossroads

    Friday, March 16th, 2012

    Colon cancer development and progression involves alterations in several cell signaling pathways. Activation of the Wnt pathway is involved in the early stages of tumor development, while inactivation of signaling through the TGF-beta pathway (which typically suppresses tumor formation) is involved in later stages. However, the interactions between these pathways remain unclear. R. Daniel Beauchamp, […]
