1 The selective Cox-2 inhibitor Celecoxib restores expression of TGF-beta RII both in vitro and in vivo and restores TGF beta-mediated transcription in RIE/PKC beta II cells. Celecoxib transforming growth factor, beta 1 Mus musculus
2 Our data define a procarcinogenic PKC beta II --> Cox-2 --> TGF-beta signaling axis within the colonic epithelium, and provide a molecular mechanism by which dietary omega-3 fatty acids and nonsteroidal antiinflammatory agents such as Celecoxib suppress colon carcinogenesis. Celecoxib transforming growth factor, beta 1 Mus musculus
