The Role Of Ledgf/P75 In Transcriptional Regulation, Jeffrey Ryan Kugelman
The Role Of Ledgf/P75 In Transcriptional Regulation, Jeffrey Ryan Kugelman
Open Access Theses & Dissertations
The Lens Epithelial Derived Growth Factor p75 (LEDGF/p75) is a chromatin bound protein whose cellular function is not yet clearly known. A role in transcriptional regulation had been previously proposed based on its interaction with the basal transcriptional machinery and on its effects on the expression of genes involved in the cellular response to environmental stresses. To further elucidate the function of LEDGF/p75, we conducted a global and unbiased evaluation of the role of this protein in gene expression. To that aim, we performed a microarray analysis of cellular gene expression in cells that are severely depleted of LEDGF/p75. To …

Phosphorylation Of The Glycine Transporter 1, Javier Vargas Medrano
Open Access Theses & Dissertations
The extracellular levels of the neurotransmitter glycine in the brain are tightly regulated by the high-affinity glycine transporter 1 (GlyT1) and the clearance of glycine depends on its rate of transport and the levels of cell surface GlyT1. Over the past years, it has been shown that PKC activation diminishes the activity and promoted phosphorylation of several neurotransmitter transporters including the dopamine, serotonin and norepinephrine transporters however, its role is unknown for the glycine transporter. To get insights into the role of PKC activation on GlyT1 regulation, we used three N-terminus GlyT1 isoforms stably expressed in porcine aortic endothelial (PAE) …
