Mammalian antimicrobial peptides (AMPs) are effectors of the innate immune response. A multitude of signals coming from pathways of mammalian pathogen/pattern recognition receptors and other proteins affect the expression of AMP-coding genes (AMPcgs). For many AMPcgs the promoter elements and transcription factors that control their tissue cell-specific expression have yet to be fully identified and characterized. Results- Based upon the RIKEN full-length cDNA and public sequence data derived from human, mouse and rat, we identified 178 candidate AMP transcripts derived from 61 genes belonging to 29 AMP families. However, only for 31 mouse genes belonging to 22 AMP families we …

The D2-D3 and ITS regions of rDNA from 33 Florida populations of Belonolaimus spp. were sequenced and subjected to phylogenetic analysis. Our objective was to derive a theoretical evolutionary framework for interpreting phenotypic differences as they relate to the taxonomy of the genus. The most striking aspect of the phylogenetic analysis is that none of the three nominal species (B. longicaudatus, B. euthychilus, and B. gracilis) are monophyletic. Additionally, two taxa appear to have discordant ITS and LSU sequences. Three major clades of B. longicaudatus exhibited discernible, overlapping, geographic foci from east to west across the peninsula. Morphological character states …
Phylogenetics Of North American Psoraleeae (Leguminosae): Rates And Dates In A Recent, Rapid Radiation, Ashley N. Egan
Phylogenetics Of North American Psoraleeae (Leguminosae): Rates And Dates In A Recent, Rapid Radiation, Ashley N. Egan
Theses and Dissertations
The scientific discipline of phylogenetics involves understanding the diversity of life in the context of history. Technological advances in molecular biology and computational power have created an exponential increase in the number and kind of phylogenetic studies, allowing exploration of all manner of questions concerning the evolutionary history of a group. This dissertation research is focused on phylogenetic theory and applying these methods to the plant tribe Psoraleeae (Leguminosae; Fabaceae) with an emphasis on North American (NAm) members. First, theory of phylogeny estimation is explored in a review chapter focusing on strengths and weaknesses of phylogenetic methodology. Second, methods are …

Transcription factor binding sites (TFBS) impart specificity to cellular transcriptional responses and have largely been defined by consensus motifs derived from a handful of validated sites. The low specificity of the computational predictions of TFBSs has been attributed to ubiquity of the motifs and the relaxed sequence requirements for binding. We posited that the inadequacy is due to limited input of empirically verified sites, and demonstrated a multiplatform approach to constructing a robust model. Results: Using the TFBS for the estrogen receptor (ER)alpha (estrogen response element [ERE]) as a model system, we extracted EREs from multiple molecular and genomic platforms …

Data from six sites in Victoria Land (72-77degrees S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties show the influence of soil properties on habitat suitability varied among local landscapes as well as across climate gradients. Species richness of metazoan invertebrates (Nematoda, Tardigrada and Rotifera) was similar to previous descriptions in this region, though identification of three cryptic nematode species of Eudorylaimus through DNA analysis contributed to the understanding of controls over habitat preferences for individual species. Denaturing Gradient Gel Electrophoresis profiles revealed unexpectedly high diversity of bacteria. Distribution of distinct bacterial communities was associated with specific …

The Phylogeography Of Prosopium In Western North America, Becky Akiko Miller
Theses and Dissertations
The mountain whitefish (Prosopium williamsoni) has been largely overlooked in population genetic analyses despite its wide distribution in discrete drainage basins in western North America for over four million years. Its closest sister taxa the Bear Lake whitefish (P. abyssicola), Bonneville cisco (P. gemmifer), and Bonneville whitefish (P. spilonotus) are found only in Bear Lake Idaho-Utah and were also included in the analyses. A total of 1,334 cytochrome b and 1,371 NADH dehydrogenase subunit 2 sequences from the Bonneville Basin, the Columbia River Sub-basin, the lower Snake River Sub-basin, the upper Snake River Sub-basin, the Green River Basin, the Lahontan …

Tumor Associated Macrophages In A Mafia Mouse Model, Adrianne Brown Clifford
Theses and Dissertations
Recent evidence has shown the important role of macrophages in both tumor development and progression. To investigate the role of macrophages we used a mouse model known as MaFIA (Macrophage Fas Induced Apoptosis) mice that allows for the selective deletion of macrophages. Mice were given melanoma cells at various stages of depletion. Tumor mass was measured and organs were processed for flow cytometry to measure melanoma cell migration. The results show that mice receiving depletion treatment have larger tumor sizes and weights than those mice retaining their macrophage population. We detect metastasis in both the lung and kidney in both …
Characterization Of The Role Of Sox9 In Cartilage-Specific Gene Regulation, Mary Ann Genzer
Characterization Of The Role Of Sox9 In Cartilage-Specific Gene Regulation, Mary Ann Genzer
Theses and Dissertations
Although advances have been made toward understanding the complex mechanisms that regulate the process of DNA transcription, the specific mechanisms of activation for many individual genes remain unknown. In this study, we focus on the role the transcription factor SOX9 plays in activating cartilage-specific genes, specifically Col9a1 and Cartilage Link Protein (CRTL1). Previously, enhancers of these genes containing single SOX9 binding sites were shown to be activated through SOX9 binding. However, the hypothesis was made that in cartilage-specific genes dimeric SOX9, as opposed to monomeric SOX9, is necessary for activation. We identified a putative binding site adjacent to each of …
