Identification Of A Novel Importin α Predominantly Expressed In Bovine Oocytes And Early Embryos., Jyothsna Tejomurtula

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early embryonic development is a complex process that involves timely and quantitative control of gene transcription. Nuclear proteins, including transcription factors and chromatin remodeling proteins, are required for initiation of transcription in early embryos prior to embryonic genome activation. The nuclear transport of these proteins is mediated by transport factors such as importins. Through analysis of EST sequences from a bovine oocyte cDNA library and the database, we identified a novel transcript which shows sequence similarity to the importin α gene. The novel transcript (contig) is represented by multiple ESTs that are only present in the oocyte library and a …

A Hairy Predicament: The Problem With Long Hair In The 1960s And 1970s, Andrew Robert Herrick Dec 2006

A Hairy Predicament: The Problem With Long Hair In The 1960s And 1970s, Andrew Robert Herrick

Graduate Theses, Dissertations, and Problem Reports (ETD)

By the mid-1970s long hair worn by much of the American youth evoked little comment and indeed was considered fashionable. But during much of the previous two decades male hair length was a contentious issue that divided the generations. The struggle over hair in many ways epitomized the sixties generation's challenge to authority and their claim to individual rights. During the era, the meaning of long hair changed dramatically from what it was during the fifties. It began as a symbol of youth culture rebellion linked to music. By the latter part of the sixties, however, it became associated with …

The Extrinsic Apoptotic Pathway In Aged Skeletal Muscle: Roles Of Tumor Necrosis Factor-Alpha And Interleukin-15, Emidio E. Pistilli

Graduate Theses, Dissertations, and Problem Reports (ETD)

Apoptosis is implicated in the loss of skeletal muscle mass following periods of reduced activity (i.e.-disuse) as well as during the normal aging process (i.e.-sarcopenia). Aging is also characterized by elevations in circulating cytokines, specifically TNF-alpha, which has been associated with the sarcopenic process. The specific signaling components that participate in the pro-apoptotic pathway downstream of the type I TNF receptor (i.e.-extrinsic apoptotic pathway) within skeletal muscle have not been clarified. Additionally, few studies have been performed with the aim of disrupting this apoptotic pathway, and thereby sparing muscle mass in the aged. Therefore, the purposes of this dissertation were …

Differential Binding Of Hnrnp K, L And A2/B1 To An Exonic Splicing Silencer Element Located Within Exon 12 Of Glucose -6 -Phosphate Dehydrogenase Mrna, Brian Nelson Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expression of most lipogenic enzymes is regulated through the effects of dietary polyunsaturated fatty acids on transcription. However, we have observed that the regulation of Glucose-6-phosphate dehydrogenase (G6PD) by polyunsaturated fatty acids occurs through a novel posttranscriptional mechanism. RNA reporter assays were used to map the cis-acting element by measuring the regulation of each RNA reporter construct transfected into primary rat hepatocytes. All RNA reporter constructs were regulated by polyunsaturated fatty acids with the exception of RNA reporter constructs lacking exon 12. Therefore, polyunsaturated fatty acids regulate the constitutive splicing of G6PD mRNA through a cis-acting element located within …
