|Title:||Analysis of Ras transformation of human thyroid epithelial cells.|
|Citation:||METHODS ENZYMOL, 2006, 407, pp. 648-660|
|Abstract:||Activation of Ras oncogene by point mutations is an early frequent event in thyroid tumorigenesis. In this chapter, we describe the use of human primary thyroid follicular epithelial cells expressing oncogenic mutant Ras by means of retroviral transduction as a biological model of human cancer initiation that provides powerful insights into thyroid tumorigenesis. We describe protocols for manipulating primary epithelial cells and describe the use of this model to dissect the signaling pathways required for Ras-induced proliferation in these cells. We also highlight the importance of studying Ras signaling in an appropriate cell context, summarizing some of the key differences identified between more widespread experimental models based on fibroblasts or rodent cell lines and primary epithelial cells.|
