The Effects Of Insulin-Like Growth Factor-1 (Igf-1) And Insulin-Like Growth Factor Receptor (Igfr) Regulation On Cognition And Structure Of Astrocytes, Sariya Khan
Honors Theses
Insulin-like growth factor-1 (IGF-1) is a neuroendocrine signaling hormone that plays an integral role in bone and tissue growth and development. Inhibition of this hormone is known to disrupt the chemistry of the brain, resulting in cognitive impairments such as those seen in many common neurodegenerative diseases. While much research has been conducted on neurons and their relation with IGF-1, the role of astrocytes still needs to be explored. Our research investigates how astrocytes are affected as a result of IGF-1 regulation. Preliminary studies in our laboratory established a connection between IGF-1 and glial fibrillary acidic protein (GFAP), and in …
Thyroxine-Dependent And -Independent Effects On Premature Aging And Myelination In Atrx Mutant Mice, Megan E. Rowland

Electronic Thesis and Dissertation Repository
ATRX is an ATP-dependent chromatin remodeler required to safeguard genomic integrity. Conditional deletion of Atrx in the mouse embryonic forebrain and anterior pituitary in AtrxFoxg1Cre mice phenocopies mouse models of progeria which display increased DNA damage, coupled with reduced lifespan, growth and subcutaneous fat. These mice also have severely low circulating levels of insulin like growth factor 1 (IGF-1) and (T4) which have been reported in models of premature aging. Based on evidence that Igf1 is activated by the ligand-bound thyroid hormone receptor, I tested whether T4 supplementation could restore IGF-1 levels and ameliorate premature aging phenotypes in Atrx …

Independent Study
Epithelial-Mesenchymal Transition (EMT) is a biological process utilized by epithelial cells to transform into motile mesenchymal cells, initiating metastasis in cancer. EMT is also utilized during development and wound healing [10]. This process allows for cancerous cells to detach themselves from their primary tumor and invade normal tissue in preferred organ sites, forming secondary tumors called metastases. Metastasis is very important in the progression of cancer in patients as it the process responsible for the mortality of patients through the collection of metastases that effect vital organs like the brain, lung, or immune system. The most common metastases for malignant …
