The function of chromatin regulators during patterning and growth in Drosophila wing disc regeneration
… regeneration, focusing on Drosophila imaginal disc regeneration and the known functions of chromatin regulators during tissue regeneration in diverse model organisms. In Chapter II, I describe a genetic screen for chromatin regulators that are required for epithelial tissue regeneration in …

big bang, a novel regulator of tissue growth in Drosophila melanogaster
… monolayer epithelial sheet of imaginal wing discs, which gives rise to the adult wing. The Hippo signaling pathway regulates tissue growth in wing development. There are several observations that link tissue growth/Hippo signaling with cell polarity and the actin cytoskeletal …

Role of endocytic trafficking during Dpp gradient formation
… fates in the target field such as the Drosophila wing disc. Although the tissue distribution as well as the actual shape and size of the Dpp morphogen concentration gradient has been visualized, the cell biological mechanisms through which the morphogen forms and maintains a gradient are still a …

The role of the wingless gene in the control of growth and pattern formation during drosophila wing development
… in the developing limbs. In the Drosophila wing imaginal disc, there are at least two such organizing centers, located at the anterior/posterior (A/P) and dorsal/ventral (D/V) compartment boundaries. The genetic hierarchies which establish these organizers are starting to be understood, and …

Dynamics of Cell Packing and Polar Order in Developing Epithelia
… the pattern of hairs in the adult Drosophila wing as well as hexagonal repacking of wing cells during development. Planar polarity proteins also control developmental processes such as convergent-extension. We present a theoretical study of cell packing geometry in developing epithelia. We use …

Glucocorticoid physiology and behavior during life history transitions in Laysan Albatross (Phoebastria immutabilis)
… to the timing of fledging in Laysan Albatrosses: wing disc loading and plasma free CORT levels. After chicks reach a critical developmental threshold, they may fledge if food delivery is inadequate or stay if it is plentiful. When food delivery is unpredictable and chicks lose energetic stores, …

TGF-beta signaling at the cellular junctions
… to the receiving cells in the developing wing epithelial cells and at the neuromuscular junctions. Cell culture studies have suggested that cells modulate morphogenetic signaling by expressing the receptors and secreting the ligand in spatially defined areas of the cell. Indeed, I have …

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 …

Multiple axes of inter-organ signaling regulate organ scaling
… null mutants of babo result in small imaginal discs and small overall body size. This is in part due to metabolic defects caused by defects in Daw signaling. In this dissertation I report how Activin-β and Myoglianin regulate body size and organ growth respectively. In Chapter one, I review …
