Maize lethal necrosis (MLN) has emerged as a serious threat to food security in sub-Saharan Africa. MLN is caused by coinfection with two viruses, Maize chlorotic mottle virus and a potyvirus, often Sugarcane mosaic virus. To better understand the dynamics of MLN and to provide insight into disease management, we modeled the spread of the viruses causing MLN within and between growing seasons. The model allows for transmission via vectors, soil, and seed, as well as exogenous sources of infection. Following model parameterization, we predict how management affects disease prevalence and crop performance over multiple seasons. Resource-rich farmers with …

Animals And Their Epibiota As Net Autotrophs: Size Scaling Of Epibiotic Metabolism On Snail Shells, Nicole Lukens, Benjamin Kraemer, Vanessa Constant, Ellen J. Hamann, Ellinor Michel, Anne M. Socci, Yvonne Vadeboncoeur, Peter B. Mcintyre

Biological Sciences Faculty Publications

Animals are heterotrophic by definition, but species from many taxonomic groups are hosts to epibiota that may alter their net metabolism. We tested the degree to which snail-shell epibiota can generate net ecosystem productivity for snails and their epibiota (snail–epibiota ecosystems; SEEs) after accounting for snail respiration. We focused on 3 species from the Lavigeria snail assemblage in Africa’s Lake Tanganyika and quantified the scaling of SEE metabolism with shell size under light and dark conditions. The metabolism of snails and their epibiota shifted significantly across the size gradient. SEEs of large snails (>20 mm) were consistently autotrophic during …

Δnp63Α And Microrna: Leveraging The Epithelial-Mesenchymal Transition, Andrew J. Stacy, Michael P. Craig, Suraj Sakaram, Madhavi Kadakia

Biochemistry and Molecular Biology Faculty Publications

The epithelial-mesenchymal transition (EMT) is a cellular reprogramming mechanism that is an underlying cause of cancer metastasis. Recent investigations have uncovered an intricate network of regulation involving the TGFβ Wnt, and Notch signaling pathways and small regulatory RNA species called microRNAs (miRNAs). The activity of a transcription factor vital to the maintenance of epithelial stemness, ?Np63a, has been shown to modulate the activity of these EMT pathways to either repress or promote EMT. Furthermore, ?Np63a is a known regulator of miRNA, including those directly involved in EMT. This review discusses the evidence of ?Np63a as a master regulator of EMT …

The removal of mRNA transcript poly(A) tails by 3'-5' exonucleases is the rate-limiting step for controlled mRNA decay in eukaryotes. Poly(A)-specific ribonuclease (PARN) is one such exonuclease that degrades poly(A) tails, and although its in vitro activity is well-characterized, PARN’s patho-physiological roles in the cell are not well understood. Prior studies have found a possible role for PARN in cancer, in that PARN expression levels in human breast cancer tissues are often decreased compared to normal control tissues. Indeed, data mined from the ONCOMINE cancer array database showed that PARN is downregulated in patient invasive breast carcinoma samples compared to …


Genomic Vs. Non-Genomic Role Of The Ahr In Human Immunoglobulin Expression, Nasser Alhamdan Jan 2017

Genomic Vs. Non-Genomic Role Of The Ahr In Human Immunoglobulin Expression, Nasser Alhamdan

Browse all Theses and Dissertations

The immunoglobulin heavy chain gene (Igh) in various animal models is regulated by numerous regulatory elements including the 3’Igh regulatory region (3’IghRR). Several transcription factors are involved in modulating the 3’IghRR including the aryl hydrocarbon receptor (AhR). The AhR is a ligand-activated transcription factor that mediates the transcription of genes involved in the metabolism of environmental toxicants such as TCDD. TCDD binds AhR and regulates immunoglobulin (Ig) expression in B cells. This modulation appears to be directly mediated by binding of the AhR to dioxin response elements (DRE) within the 3’IghRR. In human B cells, IgG secretion inhibited by TCDD …
