A Novel Role For Prolyl-Hydroxylase 3 Gene Silencing In Epithelial-To-Mesenchymal-Like Transition, Trenton Lane Place
Theses and Dissertations
The ability of cells to sense oxygen is a highly evolved process that facilitates adaptations to the local oxygen environment and is critical to energy homeostasis. In vertebrates, this process is largely controlled by three intracellular prolyl-4-hydroxylases (PHD 1-3). These related enzymes share the ability to hydroxylate the hypoxia-inducible transcription factor (HIF), and therefore control the transcription of genes involved in metabolism and vascular recruitment. However, it is becoming increasingly apparent that proline-4-hydroxylation controls much more than HIF signaling, with PHD3 emerging as the most unique and functionally diverse of the PHD isoforms. In fact, PHD3-mediated hydroxylation has recently been ...
The P63 Isoform ∆Np63Α Inhibits Epithelial – Mesenchymal Transition By Promoting The Expression Of Mir-205 In Human Bladder Cancer Cells, Mai Tran
UT GSBS Dissertations and Theses (Open Access)
p63, a p53 family member, is a transcription factor that has complex roles in cancer. This study focuses on the role of the ∆Np63α isoform in bladder cancer (BC). Epithelial – mesenchymal transition (EMT) is a physiological process that plays an important part in metastasis and drug resistance. At the molecular level, EMT is characterized by the loss of the epithelial marker E-cadherin, and the acquisition of the transcriptional repressors of E-cadherin (ZEB1, ZEB2, TWIST, SNAI1 and SNAI2). Recent publications highlight the role of microRNAs belonging to the miR-200 family and miR-205 in preventing EMT through suppression of ZEB1 and ZEB2 ...
