Anti-Ecdysteroidal Activity and Associated Toxicity of Environmental Chemicals in the Crustacean Daphnia magna.
… of the ecdysone receptor and its partner protein ultraspiracle in a cultured cell line. While juvenoids functioned as anti-ecdysteroids both in vivo and in cultured cells, 20-hydroxyecdysone showed no evidence of acting as an anti-juvenoid. We concluded that the ability of juvenoids to block …

Identification of a novel autonomous role for Ecdysone Receptor during Drosophila ovarian germ cell differentiation
… complex composed of Ecdysone Receptor (EcR) and Ultraspiracle (Usp). To elucidate whether EcR facilitates autonomous reception of ecdysone in the germline, we built germline-compatible genetic tools to manipulate EcR levels or activity. Depleting EcR mRNA or loss of EcR ligand binding in the …

Molecular mechanisms of phenotypic plasticity: Explorations of DNA methylation and transcriptional regulation using the honey bee
… transcription regulation by a nuclear receptor, Ultraspiracle (USP). Chapter 2 presents results that demonstrate that there is a functional CpG methylation system in honey bees, the first well-characterized functional DNA methylation system in insects. Catalytically active orthologs of vertebrate …

Nutrition, Hormones, Transcriptional Regulatory Networks and Division of Labor in Honey Bee Colonies
… a juvenile hormone-related transcription factor, Ultraspiracle (USP), influences the age at onset of foraging. I then use a combination of chromatin immunoprecipitation—genomic tiling microarrays, RNAi and deep mRNA sequencing to develop a model of the USP transcriptional regulatory network in fat …
