Spag17 Deficiency Impairs Neuronal Cell Differentiation In Developing Brain, Olivia J. Choi Jan 2019

Spag17 Deficiency Impairs Neuronal Cell Differentiation In Developing Brain, Olivia J. Choi

Theses and Dissertations

The development of the nervous system is a multi-level, time-sensitive process that relies heavily on cell differentiation. However, the molecular mechanisms that control brain development remain poorly understood. We generated a knockout (KO) mouse for the cilia associated gene Spag17. These animals develop hydrocephalus and enlarged ventricles consistent with the role of Spag17 in the motility of ependymal cilia. However, other phenotypes that cannot be explained by this role were also present. Recently, a mutation in Spag17 has been associated with brain malformations and severe intellectual disability in humans. Therefore, we hypothesized that Spag17 plays a crucial role in …


Effect Of Thyroid Hormones On At1r Mrna Levels In Hek 293 Cells: Implications For Early-Onset Hypertension In Children Born Of Preeclamptic Women, Amanda Eddins Jan 2008

Effect Of Thyroid Hormones On At1r Mrna Levels In Hek 293 Cells: Implications For Early-Onset Hypertension In Children Born Of Preeclamptic Women, Amanda Eddins

Theses and Dissertations

This experiment tested the effect of thyroid hormones, T3 or T4, on angiotensin II type 1 receptor mRNA levels in human embryonic kidney cells (HEK). Maternal preeclampsia is a prediction of higher ambulatory blood pressure (ABP) in the exposed offspring. The mother's blood pressure affects the blood pressure of the fetus since the placenta mediates blood flow. Thyroid hormone can increase production of angiotensinogen, which is a part of the renin-angiotensin system (RAS). RAS regulates blood pressure. Hypothesis: HEK 293 cells treated with T3 and T4 will have more angiotensin II type I receptors than those not treated with T3 …
