Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne
Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne
Legacy Theses & Dissertations (2009 - 2024)
Recurrent hypoglycemia (RH) occurs with the over administration of insulin resulting in severe hypoglycemia on a repetitive basis. This occurs most commonly among Type I Diabetics who rely on exogenous insulin replacement for management of their disease; however it is becoming increasingly common among Type II Diabetics. Although cognitive deficits are reported during hypoglycemia, the period following restoration of euglycemia has been denoted by improved hippocampally-mediated short-term and working memory in humans and rodents, respectively. RH is also associated with an altered glucocorticoid secretion profile in response to hypoglycemia. In vitro and in vivo approaches were utilized with the goal …

Study Of Protective Role Of Cytochrome P450s In Inflammatory Bowel Disease Using Cprlow Mouse Model, Xiaoyu Fan
Legacy Theses & Dissertations (2009 - 2024)
Glucocorticoids (GCs) are potent regulatory factors for inflammation. The synthesis of GCs involves several cytochrome P450 enzymes, such as mitochondrial CYP11A1, CYP11B1, and microsomal CYP21. Previous studies have indicated that the GCs, including those released from adrenal glands, and those synthesized in extra-adrenal tissues, such as intestine, exert inhibitory effects on inflammatory bowel disease (IBD). In a previous study using an intestinal epithelium (IE)-specific P450 reductase (CPR) knockout (IE-Cpr-null) mouse model, the results suggested that the intestinal P450s had a protective role in DSS-induced acute colitis. In this study, using a hypomorphic CPR mouse model (Cprlow), which presents a global …
