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) …
A Critical Review Of Telomerase Biology And Model Systems For The Study Of Telomerase, Jeremy Charles Aisenberg
A Critical Review Of Telomerase Biology And Model Systems For The Study Of Telomerase, Jeremy Charles Aisenberg
Theses and Dissertations
The study of telomere and telomerase biology holds substantial promise in uncovering the molecular process of aging and the treatment of cancers. Studies have shown that telomere shortening is directly linked to cellular aging and that telomerase expression is found in over 85% of human cancers, including 95% of all advanced malignancies. Development of effective model systems to elucidate the molecular mechanisms underlying the role of telomeres and telomerase in the processes aging and cancer is of particular importance. While inbred strains of mice have provided a wealth of information for a variety of pathways and diseases, the mouse model …
Resistance Exercise In Men Receiving Androgen Deprivation Therapy For Prostate Cancer, Daniel A. Galvao
Resistance Exercise In Men Receiving Androgen Deprivation Therapy For Prostate Cancer, Daniel A. Galvao
Theses: Doctorates and Masters
This thesis encompasses two literature reviews (chapter 2 & 3) and two experimental chapters (4 and 5) examining the available literature on exercise and cancer, resistance training and its anabolic responses in older men and women, the side effects of Androgen Deprivation Therapy (ADT) for prostate cancer and finally, the role of resistance exercise as a clinical intervention to counteract such changes as an adjuvant therapy.
The Effect Of Silencing The Wilms' Tumor 1 Gene On The Radiation Sensitivity Of Glioblastoma Cells, Dana C. Chan
The Effect Of Silencing The Wilms' Tumor 1 Gene On The Radiation Sensitivity Of Glioblastoma Cells, Dana C. Chan
Theses and Dissertations
Glioblastomas are among the most devastating of human cancers with a median survival of only 9-12 months. This type of brain tumor is incurable, largely due its remarkable proliferative capacity and resistance to current treatments. High levels of the Wilms' Tumor 1 (WTI) gene have been identified in glioblastomas, suggesting an oncogenic function. Moreover, known WT1 target genes have been implicated in resistance to radiation. To determine the role of WT1 in radiation resistance, two glioblastoma cell lines expressing WT1 were treated with siRNAs to silence this gene. Confirmation of WT1 knockdown was achieved through real-time PCR and Western blot. …
