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 …
Characterization Of The Tcof1 Gene Using A Neuroblastoma Cell Line And A Mouse Model, Lin Li
Characterization Of The Tcof1 Gene Using A Neuroblastoma Cell Line And A Mouse Model, Lin Li
Theses and Dissertations
Treacher Collins syndrome (TCS) is an autosomal dominant craniofacial development disorder and is caused by mutations in the TCOF1 gene. The TCOFl protein treacle is a nucleolar protein and may function in ribosome biogenesis.Previously, we identified downstream candidate genes using microarray analysis after manipulating Tcofl levels in a murine neuroblastoma (NB) cell line. The list of genes includes cell cycle genes as well as the transcription factors Cnbp and Tbx2, which are known to affect the cell cycle through the c-myc and p19-Mdm2-p53-p21 pathways respectively. To further characterize the cellular effects of Tcofl, stably transfected NB cell lines with overexpression …
A Twin Study Of Antisocial Behavior And Depression: Methodology, Etiology, And Comorbidity, Kelly A. Tracy
A Twin Study Of Antisocial Behavior And Depression: Methodology, Etiology, And Comorbidity, Kelly A. Tracy
Theses and Dissertations
The etiological connection between internalizing and externalizing disorders is poorly understood. This manuscript aims to investigate the roles of genes and then environment in the development of Major Depressive Disorder (MDD) and Antisocial Personality Disorder (ASPD) and the nature of their comorbidity in young adults. Data from a sample of 2,291 young adult male and female twins from the Young Adult Follow Up Study (YAFU) of the Virginia Twin Study of Adolescent Behavioral Development (VTSABD) were used to estimate the proportion of variation in these traits that can be accounted for by additive genetic, shared environmental, and unique environmental factors. …
