Analysis Of Extinction Of Fibroblast-Specific Gene Expression In Somatic Hepatic Hybrids Using Cdna Microarray Technology, Sushma K. Shrestha

Masters Theses

Extinction of tissue-specific genes in mammalian somatic cell hybrids is a well known epigenetic phenomenon and knowledge of this process is useful in understanding molecular mechanisms underlying tissue specific gene expression. Signaling proteins critical for the activation of transcription including transcription factors, co-activators, and repressors, play a role in the establishment and maintenance of tissue-specific phenotypes. Tissue-specific transcription factors are the key driving force of tissuespecific gene expression. However, mechanisms responsible for gene silencing are largely unknown.

Extinction of liver specific traits in somatic hybrids generated by the fusion of hepatoma and fibroblast cells has been well documented and is …

Interactions Of Diet And Behavior In A Death-Feigning Snake (Heterodon Nasicus), Andrew Michael Durso

Masters Theses

Studies of animal behavior in captivity are limited in their ability to explain the influence of a natural environment on behavioral ecology. Defensive behaviors vary among individual animals, between sexes and with age, as well as with other less well-known factors. The toxin-rich diet of many toad-eating snakes might enable or cause their passive terminal defensive behavior of death-feigning. I videotaped death-feigning behavior in wild Plains Hog-Nosed Snakes (Heterodon nasicus) subjected to standardized harassment. Using stable isotopes, I also described the diet of the same individuals subjected to behavioral analysis (n = 40). Heterodon had broader diets than other snakes …

A Functional Genomics Approach To Analyze Two Methionine-[Gamma]-Lyase Orthologs In "Ferroplasma Acidarmanus" Using In Vitro Enzyme Assays, Md. A. Wadud Khan

Masters Theses

Functional genomics predicts that ferl genome has two candidate genes for the production of two methionine-y-lyase (MGL) orthologs, which are thought to be pivotal for the production of methanethiol. These orthologs show a high level of protein sequence identity ( ~ 3 5%) and similarity (~60%) when compared to known MGLs. In addition, ClustalW2 alignment of ferl MGL orthologs and other known MG Ls showed a high level of similarity in amino acid residues, which are involved for the stabilization of 3D structure of MGL and in forming active site for the substrates. To confirm the predictive functions of these …

The Evolution Of Leaf Anatomy In Badiera (Polygalaceae), Laura Brauer

Masters Theses

Leaf samples from Polygalaceae: nine species of Badiera, two species of Bredemeyera, three species of Hebecarpa, and two species of Polygala were taken from herbarium specimens for anatomical observations. Several methods of rehydration were compared to a control of fresh material fixed in the field for four species of Badiera. Soaking in concentrated ammonium hydroxide proved to be the best overall means of rehydrating leaves of the genus Badiera and related genera. All leaves were embedded in paraffin for sectioning and cleared in 5% aqueous sodium hydroxide for examining epidermal features. Twelve anatomical characters were mapped onto a molecular phylogeny …

Acute Responses To Estradiol Replacement In The Olfactory System Of Apoe-Deficient And Wild-Type Mice, Britto Nathan, Michael Tonsor, Robert Struble

Faculty Research & Creative Activity

Epidemiological studies suggest that estrogen therapy protects against clinical expression of chronic neurological diseases. These beneficial effects of estrogen therapy are highly modified by apolipoprotein E (apoE) through an unknown mechanism. We examined the short-term effects of estradiol replacement in ovariectomized mice on apoE expression and markers for cell proliferation, reactive gliosis, neuronal maturation, and synaptogenesis in the primary olfactory pathway of wild-type (WT) and apoE knockout (KO) mice. Three days of estradiol replacement increased apoE expression in the olfactory nerve and in the glomerular layer. Estradiol treatment also increased cell proliferation, total cell numbers, number of mature neurons in …
