Project description:We compared ecdysone receptor (EcR)-dependent gene expression in the Drosophila fat body on 0.15 M sucrose and 0.5 M sucrose high-sugar diets in order to gain insight into the role of this gene during caloric overload. Phenotypic analyses showed an increased severity of EcR RNAi phenotypes with increasing dietary sugar concentration. Because EcR is a transcription factor, we performed RNA-seq studies to identify transcriptional targets that might underlie insulin resistance downstream of EcR RNAi.

Project description:In Drosophila, male-specific FRU (FRUM) is required to establish the potential for courtship behaviors, but the downstream effectors of FRUM during development are largely unknown. A microarray-based approach identified genes that are differentially expressed as a consequence of FRUM in pupae, in both whole body and CNS tissues. Genes were also identified that are sex-differentially expressed in CNS tissues. The FRUM-regulated sets were significantly overrepresented with genes also regulated by the ecdysone regulatory pathway. Two EcR isoforms (EcRA and EcRB1) are expressed in FRUM-expressing neurons during distinct periods of metamorphosis. Males with abrogated EcRA function in FRUM-expressing neurons aggressively court other males. Transcriptional profiles of mutants with abrogated EcRA function in the fru circuit demonstrate that EcR and FRUM regulate common gene sets, including the early gene broad. These results demonstrate a novel role for EcR in specifying male courtship behavior through its actions specifically in the FRUM neural circuitry.

Project description:The subject of the current study is the finding of possible molecular partners of Drosophila EcR receptor. Two labelling enzymes (BioID2 and APEX2) were fused to EcR or Usp to biotin label the surrounding proteins. All fused proteins were expressed using the Act5C promoter in Drosophila S2 cells. To ensure functionality of the generated proteins, we verified their ability to bind EcR and Usp sites in the Drosophila genome with the ChIP-Seq. Our results demonstrate that EcR and Usp fusions can be recruited to genomic sites endogenous for the EcR/Usp proteins. Conversely, unfused BioID2 and APEX2 enzymes do not bind to EcR/Usp sites. A more in-depth study was conducted to clarify the association of EcR/Usp with one of the detected proteins, CP190, a well-described cofactor of Drosophila insulators. ChIP-Seq experiments revealed an enrichment of CP190 binding on transcription start and end sites of 20E-dependent genes but not at EcR/Usp-bound enhancers.

Project description:We used the DamID method to systematically identify the binding sites of Ecdysone Receptor and its heterodimeric partner USP across the whole genome in Drosophila Kc cells. We find that the EcR sites are a subset of the USP sites and that only a proportion are ecdysone regulated from an accompanying ecdysone profiling study. The role of EcR/USP in the ecdysone network appears to be coordinated by the recruitment of many transcription factors as well as signaling molecules.
