Session Description: The genetic basis of most human cancers has been generally attributed to germline alterations in tumor suppressors, DNA repair genes, and occasionally oncogenes. However, emerging data indicate that alternative genetic and epigenetic pathways likely play an important role in tumor development in several intriguing disorders. This session will explore three unique mechanisms of malignant transformation that have been traditionally characterized in somatic cancer cells and will, in each example, expand on recent discoveries that highlight their importance in conferring hereditary susceptiblity to cancer. The roles of aberrant telomerase, microRNA, and epimutations indicate that the pathway to cancer predisposition is far more complex than had been previously understood. Furthermore, as these complex mechanisms are more carefully dissected, it becomes more practical to utilize genetic and genomic information to develop rational approaches to genetic testing and early detection surveillance protocols. The last talk in the session will weave these into the framework of the novel molecular mechanisms discussed in the first three presentations.
