Can Changes In Sr Protein Acetylation Affect Alternative Splicing?, Heather E. Knupp
Graduate Theses, Dissertations, and Problem Reports
Cellular phenotype and function is determined by the cellular proteome. Within the cellular proteome there are processes that have a potential to significantly alter the composition of the proteome. One such process is called alternative splicing. Splicing is the removal of introns from a pre-mRNA sequence and the remaining pre-mRNA sequences, called exons, are combined. Alternative splicing modifies the intron-exon combination, and can form novel products from the different arrangement of the coding sequences. This process, due to the high potential for new, possibly unwanted products, is highly regulated and can occur in a tissue and developmental-specific fashion. The misreguation …

Electron Paramagnetic Resonance And Electron-Nuclear Double Resonance Characterization Of Point Defects In Titanium Dioxide Crystals, Adam Brant
Graduate Theses, Dissertations, and Problem Reports
Electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) are used to characterize several point defects in titanium dioxide (TiO2) single crystals in the rutile phase. A defect reported in 1961 by P. F. Chester called the "A Center" is assigned to a neutral hydrogen donor. Many researchers believe that the model for this S = 1/2 defect is an interstitial titanium ion (Ti3+) and that Ti3+ interstitials are the most dominant shallow donor in TiO 2. I show that the model for the A center is a neutral hydrogen donor and suggest that the Ti3+ interstitial model is not …

Repression Of Phlpp By Mir-190 Contributes To Arsenic-Induced Akt Activation And Carcinogenesis, Kevin John Beezhold
Graduate Theses, Dissertations, and Problem Reports
Arsenic is a well-studied human carcinogen. The mechanism by which arsenic induces cancer, however, is not fully understood. It is known that as a general stress inducer, arsenic can activate kinases, such as mitogen-activated protein kinases, leading to over activation of transcription factors. These transcription factors, including AP-1, NF-kB and Myc, are known to regulate the expression of early response genes, and likely to regulate miRNAs. The expression of miRNAs is often altered in cancer and other proliferative disorders. It is highly probable that miRNAs whose expressions are altered by arsenic will play a significant role in carcinogenesis. To test …

The Social Transformation Of Coffee Houses: The Emergence Of Chain Establishments And The Private Nature Of Usage, Dawn Marie Lozzi
The Social Transformation Of Coffee Houses: The Emergence Of Chain Establishments And The Private Nature Of Usage, Dawn Marie Lozzi
Graduate Theses, Dissertations, and Problem Reports
Much attention is given to Ray Oldenburg's (1989) concept of third places as environments that offer visitors friendship and a sense of community. However, given that coffee houses have moved from small-scale businesses to chain-owned and many people now use them to work on laptops, this idealized image of the coffee house also may be changing. Few empirical studies have addressed such possibilities. Using unobtrusive observation data on three independently-owned coffee houses and three chain-based coffee houses, this research examines the concept of third places to better understand the ways in which modern coffee houses live up to Oldenburg's social …
