Regulation Of Telomerase Expression In Stem Cell Reprogramming, Patrick Sachs
Regulation Of Telomerase Expression In Stem Cell Reprogramming, Patrick Sachs
Theses and Dissertations
A great need exists for an abundant, easily accessible source of patient-specific cells that will function for use in regenerative medicine. One promising source is the adult stem cell derived from adipose tissue (ASCs). Isolated from waste lipoaspiration, these cells could serve as a readily available source for the regeneration of damaged tissues. To further define the biology of ASCs, we have isolated multiple cell strains from different adipose tissue sources, indicating wide-spread distribution in the body. We find that a widely used set of cell surface markers fail to distinguish ASCs from normal fibroblasts. However, our ASC isolations are …
Dual Regulation Of Telomerase Activity By Hsf1 And Its Role In Prostate Cancer Progression, Keith Douglas Ostergaard Jensen
Dual Regulation Of Telomerase Activity By Hsf1 And Its Role In Prostate Cancer Progression, Keith Douglas Ostergaard Jensen
Theses and Dissertations
It has been shown that the key components of the hsp90 chaperone complex, including hsp90, p23, hsp70, hsp40, and HOP (p60), associate with telomerase; however, their specific roles in telomerase function and tumor progression have not yet been defined. HSF1, the primary mammalian heat shock protein transcription factor, may affect telomerase activity and transformation by regulating the expression of several hsp90 chaperone complex proteins in response to stress as well as regulating the transcription of hTERT, the protein subunit of telomerase.In our in vitro model of prostate cancer progression, as cells progress from immortal but non-tumorigenic (P69) to tumorigenic (M2182) …
