Effect Of Life History On Microrna Expression During C. Elegans Development, Xantha Karp, Molly Hammell, Maria C. Ow, Victor R. Ambros

Animals have evolved mechanisms to ensure the robustness of developmental outcomes to changing environments. MicroRNA expression may contribute to developmental robustness because microRNAs are key post-transcriptional regulators of developmental gene expression and can affect the expression of multiple target genes. Caenorhabditis elegans provides an excellent model to study developmental responses to environmental conditions. In favorable environments, C. elegans larvae develop rapidly and continuously through four larval stages. In contrast, in unfavorable conditions, larval development may be interrupted at either of two diapause stages: The L1 diapause occurs when embryos hatch in the absence of food, and the dauer diapause occurs …

Theses and Dissertations
Elucidating the molecular mechanisms that play a role in cellular morphogenesis is critical to our understanding of brain development and function. The midbrain-hindbrain boundary (MHB) is one of the first folds in the vertebrate embryonic brain and is highly conserved across species. We used the zebrafish MHB as a model for determining the molecular mechanisms that regulate these cell shape changes. Cellular morphogenesis is tightly regulated by signaling pathways that rearrange the cytoskeleton and produce mechanical forces that enable changes in cell and tissue morphology. The generation of force within a cell often depends on motor proteins, particularly non-muscle myosins …

Analyzing The Interactions Of Kdm5/Lid And Sin3 In Drosophila Melanogaster, Ambikai Gajan
Wayne State University Dissertations
SIN3, the scaffold protein of a histone modifying complex is conserved from yeast to mammals. Drosophila SIN3 associates with both a histone deactylase RPD3 and a histone demethylase dKDM5/LID. Immunopurification of dKDM5/LID verifies a previously observed interaction with SIN3 and RPD3. Furthermore, deficiency of dKDM5/LID phenocopies deficiency of SIN3 in many cellular and developmental processes. Knockdown of both Sin3A and lid hinder cell proliferation in Drosophila cultured cells and developing flies. Knockdown of these genes also results in a curved wing phenotype implicating a role in wing development. Analysis of underlying gene expression changes upon decreased expression of SIN3, dKDM5/LID …

Fungal spores as a prominent type of primary biological aerosol particles (PBAP) have been incorporated into the COSMO-ART (Consortium for Small-scale Modelling- Aerosols and Reactive Trace gases) regional atmospheric model. Two literature-based emission rates for fungal spores derived from fungal spore colony counts and chemical tracer measurements were used as a parameterization baseline for this study. A third, new emission parameterization for fluorescent biological aerosol particles (FBAP) was adapted to field measurements from four locations across Europe. FBAP concentrations can be regarded as a lower estimate of total PBAP concentrations. Size distributions of FBAP often show a distinct mode at …
