Cytokines in Colitis-Associated Cancer: Potential Drug Targets?

2008

In inflammatory bowel disease (IBD), such as UC and CD, the development of colorectal carcinoma can be initiated through chronic inflammation, depending on the duration and severity of the disease. Growing evidence supports a role for various cytokines, released by epithelial and immune cells, in the pathogenesis of colitis associated cancer (CAC). For instance, TNF-alpha has been recently shown to promote tumor development in experimental colitis. Due to its role in the pathogenesis of IBD, TNF-alpha blockade has become one of the cornerstones of IBD therapy. Thus, anti-TNF-alpha strategies could also provide effective anti-tumor therapies. TGF-beta has been shown to attenuate an anti-tumo…
