Biological Clocks, Inflammation, And Multiorgan Damage In Sickle Cell Disease, Morayo Adebiyi May 2018

Biological Clocks, Inflammation, And Multiorgan Damage In Sickle Cell Disease, Morayo Adebiyi

UT GSBS Dissertations and Theses (Open Access)

Sickle cell disease (SCD) is a dangerous condition caused by a genetic mutation on the human beta-globin gene that contributes to erythrocyte sickling, the hallmark of the disease. Previous metabolomics studies have confirmed that elevated sphingosine kinase 1 (SphK1) mediates sphingosine-1-phosphate (S1P) production to promote erythrocyte sickling. S1P signals via five S1P receptors (S1PR) regulates several pathophysiological functions.

In the first chapter of this dissertation, I explored the role of S1PRs in SCD by utilizing pharmacologic and genetic tools. To determine the role of S1P-S1PRs signaling in SCD, I treated humanized Berkeley sickle mice (Berkeley HBS mice), with FTY720, a ...


Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim May 2016

Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim

UT GSBS Dissertations and Theses (Open Access)

Preeclampsia (PE) is a severe, acute disease of pregnancy affecting approximately 8% of pregnant women after week 20 of gestation. PE is characterized by hypertension and renal damage reflected by proteinuria and has significant morbidity to both mother and fetus. Maternal symptoms range from headaches, nausea, edema, to visual changes, but once maternal symptoms present, damage to the fetus has begun. Mothers who progress untreated through the disease can also experience a condition called eclampsia characterized by seizure, coma, and, ultimately, death. PE-affected newborns experience features similar to prematurity—abnormal lung and renal development, intrauterine growth retardation (IUGR), and, possibly ...
