The Effect Of Nutrients Upon The Activity Of Sr Proteins, Callee Mcconnell Walsh Jan 2009

The Effect Of Nutrients Upon The Activity Of Sr Proteins, Callee Mcconnell Walsh

Graduate Theses, Dissertations, and Problem Reports (ETD)

RNA splicing is an important component of gene expression that contributes immensely to the biological complexity of higher eukaryotes. The regulation of splicing by external stimuli, such as nutrients, is poorly understood, however. The experiments contained herein sought to understand how the activity of splicing factors called SR proteins is regulated by insulin and polyunsaturated fatty acids in the liver using the model mRNA glucose-6-phosphate dehydrogenase (G6PD). RNA affinity and chromatin immunoprecipitation experiments demonstrated that refeeding of rodents stimulates the binding of SR proteins to the splicing regulatory element of G6PD; and this was especially relevant for SRp20. In vitro …

Periconceptional Treatment With Growth Hormone Alters Fetal Growth And Development In Sheep, Jill Marie Koch May 2008

Periconceptional Treatment With Growth Hormone Alters Fetal Growth And Development In Sheep, Jill Marie Koch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Altering the fetal environment can modify the composition or growth rate of the fetus, a concept known as fetal programming. A majority of the research in this area has focused on intrauterine growth restriction (IUGR), which has been linked to adult diseases. A few studies have attempted to ameliorate the negative effects of IUGR, by applying growth promoters late in gestation, and have only observed transient effects. Our laboratory has previously shown that growth hormone (GH) treatment around the time of breeding alters the uterine environment early in gestation and results in larger lambs at birth. Therefore there were three …
