Mapping telomerase reverse transcriptase (hTERT) domains that contribute to tumorigenesis

Telomerase is a ribonucleoprotein that maintains telomere. It is activated in greater than 85% of human neoplasms. Traditionally, reactivation of telomerase during tumorigenesis was thought to be required solely to impart an indefinite lifespan. Recently, however, several studies have suggested that telomerase may contribute to tumorigenesis via an additional mechanism that is independent of its role in telomere lengthening. We sought to identify the region(s) of hTERT that contribute to this non-classical role of telomerase. We proposed to identify such regions by their ability to impart a tumorigenic phenotype in ALT cells transduced with activated Ras. Also, we attempted to develop methods to demonstrate that this role is not dependant of telomerase localizing to the telomere. The strategies employed and the progress gained toward each goal is presented in this thesis.
