Arachidonic Acid Signaling In Invasive And Non-Invasive Breast Cancer Cells, Debarshi Roy
Arachidonic Acid Signaling In Invasive And Non-Invasive Breast Cancer Cells, Debarshi Roy
Open Access Theses & Dissertations
Breast cancer is the second largest cause of cancer-related deaths in women all over the world. Epidemiological studies suggest that the consumption of high-fat diets can promote the incidence of breast cancers in both developed and developing countries. In particular, the lipid-rich diet contains arachidonic acid (AA, a C20:4 polyunsaturated fatty acid), which has been shown to be associated with tumor formation in breast tissues. Nevertheless, the actual mechanism by which AA induces the metastatic transformation and malignancy is not well understood. The goal of my dissertation, therefore, is to identify the molecules and unravel the pathways that participate in …
Identification And Characterization Of Fkbp52-Specific Inhibitors For The Treatment Of Prostate Cancer, Johanny Tonos De Leon
Identification And Characterization Of Fkbp52-Specific Inhibitors For The Treatment Of Prostate Cancer, Johanny Tonos De Leon
Open Access Theses & Dissertations
Steroid hormone receptors require the ordered assembly of various chaperone and cochaperone proteins in order to reach a functional state. The final stage in the receptor maturation process requires the formation of a mutimeric complex consisting of Hsp90 dimer, p23, and one of several large immunophilins. Studies conducted previously demonstrated that the large immunophilin FKBP52 acts to potentiate glucocorticoid, androgen, and progesterone receptor signaling pathways. The aim of these studies was to identify and characterize FKBP52-specific inhibitors that would not only serve as tools for the pharmacological analysis of FKBP52-receptor interactions, but may also lead to novel drugs with significant …
Phosphorylation Of The Glycine Transporter 1, Javier Vargas Medrano
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) …
