%0 Journal Article %T Tumor Suppressor Role of Notch1 and Raf-1 Signaling in Medullary Thyroid Cancer Cells %A Muthusamy Kunnimalaiyaan %A Megan R. Haymart %A Herbert Chen %J Translational Oncogenomics %D 2007 %I %X There is a growing body of literature suggesting that signaling based therapy might be a potential approach for medullary thyroid cancer (MTC). In this review we focus on the tumor suppressor role of Notch1 and Raf-1 signaling in MTC. Interestingly these two pathways are minimally active or absent in these tumors and activation of Notch1 and Raf-1 significantly reduces tumor growth in vitro. Therefore, identification of compounds that induce these pathways could be a potential strategy to treat patients with MTC. %K medullary thyroid cancer %K Notch1 %K Raf-1 %K achaete scute complex-like 1 %K Notch1 activating compound %K ZM336372 %U http://la-press.com/article.php?article_id=234
