Transcriptional responses of expressing Drosophila melanogaster IRP1A alleles in the prothoracic gland

Project description:We report the genome-wide profiling of hand-dissected ring glands that expressed one of the six flag-tagged transgene: IRP1AWT and IRP1BWT, which are both wild-type; IRP1AC450S and IRP1BC447S, both of which can only assume the apo-form; as well as IRP1A3R3Q and IRP1B3R3Q, both of which are presumed to be non-RNA-binding

Transcriptome analysis of Drosophila melanogaster third instar larval ring glands points to novel functions and uncovers a cytochrome p450 required for development

Project description:In Drosophila melanogaster larvae the ring gland is a control center that orchestrates major developmental transitions. It is a composite organ, consisting of the prothoracic gland, the corpus allatum and the corpora cardiaca, each of which synthesizes and secretes a different hormone. Until now, the ring gland’s broader developmental roles beyond endocrine secretion have not been explored. RNA sequencing and analysis of a new transcriptome resource from D. melanogaster wandering third instar larval ring glands has provided a fascinating insight into the diversity of developmental signalling in this organ. We have found strong enrichment of expression of two gene pathways not previously associated with the ring gland: immune response and fatty acid metabolism. We have also uncovered strong expression for many uncharacterized genes. Additionally, RNA interference against ring gland-enriched cytochrome p450s Cyp6u1 and Cyp6g2 produced a lethal ecdysone deficiency and a juvenile hormone deficiency respectively, flagging a critical role for these genes in hormone synthesis. This transcriptome provides a valuable new resource for investigation of roles played by the ring gland in governing insect development.

The proteomics analyses of different tissues(the posterior silk gland of wild silkworm)

Project description:We collected a total of 9.8 million mass spectra data generated in the laboratory from the proteomics analyses of different silkworm tissues, including the posterior silk gland (29), middle silk gland (30), ovary and testis (31), head (32), brain, prothoracic glands, subesophageal ganglion (33), hemolymph (34), fat body (35) and embryo (36,37) of domestic silkworm, and the posterior silk gland of wild silkworm (38).

Genome-winding binding profile of KDM5 in Drosophila larval prothoracic gland cells via Targeted DamID analysis

Project description:kdm5 is an essential gene in Drosophila that has critical developmental roles in the prothoracic gland cells of the larval ring gland. To profile KDM5 binding within these cells and this developmental stage, we performed Targeted DamID (TaDa). By profiling the nearest genes to significant TaDa peaks (FDR < 0.01), we identified 5815 candidate KDM5 target genes. Interestingly, 42% of these candidate KDM5 target genes appear to be conserved across multiple cellular contexts in Drosophila and span many cellular processes for future investigation.

Gene expression of hormone-treated U2OS cells expressing GR alleles

Project description:Glucocorticoid receptor (GR) is a hormone-activated, DNA-binding transcriptional regulatory factor, which regulates diverse aspects of physiology. GR recognizes specifically imperfect palindromic six base pair “half sites separated by thoursee base pair “spacers”, binding as an inverted dimer. In vivo, different GR target genes depend on different functional surfaces of GR for proper regulation, but rules dictating the relationship between sequence and utilization of distinct GR functional surfaces remain unknown.In this study, we measured changes in gene expression and genomic occupancy upon glucocorticoid treatment of isogenic cultured human cell lines expressing alleles of GR bearing differences in particular functional surfaces.

Expression data from immature dendritic cells (iDC) expressing HIV-1 Tat alleles and mutants

Project description:HIV-1 Tat induces the expression of interferon (IFN)-inducible genes in immature dendritic cells (iDC) in the absence of IFN production. We evaluated how three alleles of Tat and some Tat mutants differ in cellular gene modulation and whether a similar gene induction pattern could be detected by treating cells with IFN’s. The three alleles and mutants, with the exception of mutants TatSF21-47 and TatSF2G48-R57A that do not localize in the nucleous, modulated to different degrees IFN-inducible genes without concomitant induction of IFN’s. The first exon TatSF21-72 and the minimal transactivator TatSF21-58, all induced genes to a significantly greater extent than full-length Tat. The 2nd exon appears to diminish the gene modulation that can be observed when the first exon alone is expressed. We investigated the effect of various Tat alleles and mutants on host cell gene expression in immature dendritic cells (iDC). The cells were infected with adenoviruses expressing the Tat constructs.

RNA-seq profiling of Drosophila larval ring glands of kdm5 null mutants

Project description:kdm5 is an essential gene in Drosophila that has critical developmental roles in the prothoracic gland cells of the larval ring gland. We performed a bulk transcriptome analysis of the larval ring gland in w[1118] (wild type) and kdm5[140] (null mutant) in order to identify genes in the prothoracic gland involved in the lethality of kdm5 null mutants. We found that the absence of kdm5 causes dysregulation of genes involved in various metabolic pathways. In particular, genes both bound by KDM5 and differentially expressed in this cell type are involved in regulation of mitochondrial biology and autophagy.

Genome-wide transcriptional analysis of PTTH-stimulated Bombyx prothoracic gland

Project description:This is part of a cross-species approach to characterize transcriptional response of the insect prothoracic gland (PG) to the prothoracicotropic hormone (PTTH). Genome-wide response of the PG to PTTH was analyzed in vitro in Bombyx and in vivo in Drosophila, and the results were compared to identify common components in the PTTH signaling pathway. Bombyx PGs were incubated in vitro for 1 or 3 hours with or without 10 nM recombinant PTTH. 12-18 larvae were used to prepare each RNA sample, and the experiment was conducted twice. Total RNA samples from two independent preparations were combined to obtain a single RNA sample for each treatment, which was subjected to RNA-seq.
