Examination Of Methylation Status And Occupancy Of Dna Methylation Modifying Proteins On Regulatory Regions Of The Dax-1 Gene, Caroline P. Riedstra
Examination Of Methylation Status And Occupancy Of Dna Methylation Modifying Proteins On Regulatory Regions Of The Dax-1 Gene, Caroline P. Riedstra
Master's Theses
Epigenetic modifications influence gene expression and thereby play a pivotal role in development and disease. Misregulation and mutations in the DAX-1 gene, or Dosage-Sensitive Sex Reversal, Adrenal Hypoplasia Congenita, Critical Region on the X chromosome, gene 1, have been implicated in Adrenal Hypoplasia Congenita (AHC) and Dosage Sensitive Sex Reversal (DSS). The orphan nuclear hormone receptor DAX-1 is expressed predominantly in tissues such as the testes, ovaries, breast, adrenal cortex, and lung. Critically, DAX-1 may serve as an indicator of aberrant growth in these tissues. Here we hypothesize that DAX-1 is epigenetically regulated, specifically in cancer cells, thereby reducing its …

Master's Theses
Notch-1 is a cell fate regulatory protein and a potent breast oncogene. Notch-1 and its ligand Jagged-1 are over-expressed in human breast cancers that are associated with poor overall survival (Reedijk, Odorcic et al. 2005). Deregulated Notch signaling may contribute to tumorigenesis by increasing proliferation, inhibiting differentiation, and preventing apoptosis (Miele, Golde et al. 2006). The mitogen-activated protein kinase (MAPK) pathway is a critical cell signaling pathway that has been implicated in the development and progression of cancer (Hanahan and Weinberg 2000). Four major MAPK pathways are involved in both cell growth and apoptosis. The regulation of these pathways is …
