Elucidating The Targets And Function Of The Mlr Compass-Like Complex During Development, David Joseph Ford
Elucidating The Targets And Function Of The Mlr Compass-Like Complex During Development, David Joseph Ford
Dissertations
MLR COMPASS-like complexes are highly-conserved epigenetic regulators required for enhancer establishment and subsequent reprogramming during differentiation and development. Mutation of MLR complex subunits in humans is associated with cancer and developmental disorder, yet much remains to be determined concerning both the healthy and disease-altered functions of these complexes. Using the developmental model Drosophila melanogaster, I further elucidate the functions of the MLR complex during in vivo organ development as well as stress response. I characterize the miRNa bantam as a regulatory target of the complex, required for proper tissue patterning during wing and compound eye formation. in the same systems …
Effects Of Neuronal Nogo-A On Properties Of Excitatory Synapses Of The Sensorimotor Cortex, Alicia Marie Case
Effects Of Neuronal Nogo-A On Properties Of Excitatory Synapses Of The Sensorimotor Cortex, Alicia Marie Case
Dissertations
Recovery after central nervous system (CNS) injury has long been a challenge for clinical investigators. Blockade of the oligodendrocyte-associated inhibitor Nogo-A has shown great promise in promoting neuronal regeneration, sprouting, and plasticity, as well as functional recovery in rodent and primate models of CNS injury. The high expression of Nogo-A in neurons of the postnatal CNS led us to look for potential roles of this protein in this stage of development. We hypothesized that postnatal, neuronal NogoA influences the density and morphology of dendritic spines in the developing CNS, in part, by regulating the maturation and stability of glutamatergic synaptic …
Morphogenesis Of The Bacillus Anthracis Spore, Michael Mallozzi
Morphogenesis Of The Bacillus Anthracis Spore, Michael Mallozzi
Dissertations
With the ability to shut down metabolism, survive exposure to high degrees of heat, ultra-violet and ionizing radiation, digestive enzymes, and antimicrobials, the bacterial spore is one of the most-resistant forms of life on earth. Although most spores are harmless, several species' spores cause serious diseases such as tetanus, anthrax, gas gangrene, botulism, and diarrhea. Spore-forming bacteria differentiate into spores in response to stresses (especially starvation) in a multi-stage developmental pathway involving the coordinated expression of hundreds of genes and the formation of specialized protective organelles which surround and protect the spore during dormancy. The Bacillus anthracis spore (the causative …
