(Submitter supplied) Pulses of the steroid hormone ecdysone act through transcriptional cascades to direct the major developmental transitions during the Drosophila life cycle. These include the prepupal ecdysone pulse, which occurs 10 hours after pupariation and triggers the onset of adult morphogenesis and larval tissue destruction. E93 encodes a transcription factor that is specifically induced by the prepupal pulse of ecdysone, supporting a model proposed by earlier work that it specifies the onset of adult development. more...

Analysis of ecdysone receptor (EcR) depleted animals 4 hours before to 4 hours after the start of pupariation. EcR is part of receptor complex for 20-hydroxyecdysone (20E), a hormone that triggers developmental transitions in insects. Results provide insight into the mechanisms regulated by 20E.

Analysis of animals before and after pupariation. A pulse of steroid hormone 20-hydroxyecdysone (20E) at late 3rd instar triggers puparium formation; a second 20E pulse after pupariation marks the prepupal-to-pupal transition. Results provide insight into the molecular mechanisms of 20E signaling.

(Submitter supplied) Previously we and other teams have found that 20E modulates the induction and expression of antimicrobial peptides (AMPs) in immune-challenged Drosophila cell culture or whole animals. To identify potential downstream targets of 20E involved in modulating the immune response we used Affymetrix gene chips (microarrays) to compare the transcriptomes of Drosophila S2* cells treated or not with 20E for 24 hours.

(Submitter supplied) Translational stop codon readthrough generates C-terminally extended protein isoforms. While evidence mounts of readthrough as a global phenomenon, proofs of its functional consequences are scarce. We show that readthrough of the Drosophila POU/Oct transcription factor gene drifter (dfr) occurs at a high rate and in a spatiotemporal manner in vivo, reaching more than 50% in the larval prothoracic gland. more...

(Submitter supplied) Terminal differentiation of epidermal cells in Drosophila embryos requires the activity of a transcription factor. Svb is necessary and sufficient to induce this process. pri is a regulator of Svb activity, converting it from a repressor into an activator. To characterize the downstream Svb and pri effectors in cell morphogenesis, we performed microarrays in wt, svb -/- (no gene) and pri -/- (svb repressor) mutant conditions.
