The role of Decapentaplegic (Dpp) in Drosophila wing development
… cell survival and proliferation in Drosophila wing development. To investigate the role of Dpp in Drosophila wing development, three aspects of the patterning role of Dpp have been analyzed. First, I investigated the cellular responses to Dpp signaling by a loss of function strategy. The …

The role of the wingless gene in the control of growth and pattern formation during drosophila wing development
Recent work on Drosophila limb development has indicated that short-range interactions between distinctly specified populations of cells (compartments) establish organizing centers at compartment boundaries. These organizing centers direct pattern formation and growth in the developing limbs. In …

Lysine Specific Demethylase-1 and the Brahma Chromatin Remodeling Complex Regulate Conserved Signaling Pathways During Drosophila Wing Development
… role in regulating the proper expression of many developmentally important genes, including those required for eye and wing tissue morphogenesis. A temperature sensitive mutation in one of the core subunits, SNR1 (SNF5/Ini1/SMARC B1), results in reproducible wing patterning phenotypes that can be …

Pre- to post-fledging carryover effects and the post-fledging ecology of the Dickcissel (Spiza americana)
… use. Specifically, I sought to address the following questions: (1) Do body condition and wing development at fledging predict juvenile survival during the post-fledging period? (2) What is the relative influence of body condition and wing development on cause-specific mortality (predation and …

Functional Characterization of a Cathepsin L in Drosophila Melanogaster
… tube that invasively grows toward and into the wing imaginal disc. The unfolding of Drosophila wing is a process following eclosion with a cuticular bilayer replacing epithelial cells originally packing the wing. We reasoned that protease functions might be needed for the invasion of ASP into …

Compressive strength prediction for composite unmanned aerial vehicles
… (1987) and can be directly applied to actual development, quality control or failure investigation programs. There is very good agreement between actual and predicted compressive strength at -125F and room temperature. At 180F, the predicted strength is conservative. Aurora Flight Sciences …

Studies of the cell biological function of the Amyloid Precursor Protein (APP) family in Drosophila melanogaster and mammals
… of APP, APLP1, or APLP2 in the Drosophila wing leads to cell adhesion defects, which was evident from detached cell layers and incomplete wing development. It was further revealed that the induced, so called blistered wing phenotype depends on the extracellular domain and membrane anchoring …

Characterization of the Ets-family transcription factor Ets98B in Drosophila
… metazoans and plays key roles in normal development and oncogenesis. Prostate-Derived Ets Factor (PDEF), a recently identified family member in humans, is expressed in a subset of normal epithelial tissues in adults. Its expression appears to be altered in many prostate and breast …

Age-specific mortality, pre- to post-fledging carryover effects, and the timing of fledging in altricial songbirds
… for pre- to post-fledging carryover effects of wing development in all species I examined, with individuals with less developed wings exhibiting poorer flight ability and experiencing higher rates of mortality after fledging. I also found that carryover effects operating at the species level …

Thermodynamic and topological characterization of living systems
… the underlying dynamics, revealing that fly wing development solves a topological optimal transport problem, and enables comparisons across a wide range of different systems from zebrafish brains to bacterial colonies.

big bang, a novel regulator of tissue growth in Drosophila melanogaster
… organisms need to control their size throughout development and adult life in the face of challenges such as rapid growth. Unraveling the mechanisms that regulate tissue growth in epithelial tissues, in order to generate organs of correct size and proportion, remains a crucial goal of …

Analyzing The Interactions Of Kdm5/lid And Sin3 In Drosophila Melanogaster
… 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 …

The Breeding Ecology of Least Bitterns (Ixobrychus exilis) at Agassiz and Mingo National Wildlife Refuges
… success, egg and clutch measurements, hatchling developmental rates, and habitat measurements. Data suggest geographical variation in clutch size, relative growth patterns of hatchlings, and nest densities. A total of 74 nests were found at Mingo and 120 nests at Agassiz. Nest success was lower …

Digit formation during embryonic development of bats and mice
… HL, has seen extensive research into bat wing development in an effort to determine the molecular mechanism driving limb development. A recent RNA-seq and ChIP-seq study carried out on M. natalensis showed differences in FL and HL activity for several genetic pathways known to be involved …

Bioinformatics analyses of non-coding genomic elements
… to characterize gene expression changes during development in the fetal limb tissue of several mammalian species, to better understand the mechanistic differences across evolutionary lineages. We compared development in four species of mammals. The house mouse was used since it is a …

Unraveling The Genetic Mechanisms Involved In The Evolution And Development Of The Thoracic Appendages In Insects

Investigating the evolution and functionality of closely related Wnt ligands in Drosophila melanogaster
… plays a pivotal role in orchestrating diverse developmental processes across metazoans. There are thirteen subfamilies of Wnt ligands, seven of which are represented in the model organism Drosophila melanogaster. Similar expression of some Drosophila Wnt genes has been observed in several …
