Tissue-specific gene expression and ecdysone-regulated genomic networks in Drosophila.

Li Tong-Ruei TR White Kevin P KP

Developmental cell 20030701 1

During insect metamorphosis, each tissue displays a unique physiological and morphological response to the steroid hormone 20-hydroxyecdysone (ecdysone). We assayed gene expression in five tissues during metamorphosis onset. Larval-specific tissues display major changes in genome-wide expression profiles, whereas tissues that survive into adulthood display few changes. In one larval tissue, the salivary gland, we used a computational approach to identify a regulatory motif and a cognate transcri ...[more]

Life cycle of Drosophila melanogaster

Project description:Molecular genetic studies of Drosophila melanogaster have led to profound advances in understanding the regulation of development. Here we report gene expression patterns for nearly one-third of all Drosophila genes during a complete time course of development. Mutations that eliminate eye or germline tissue were used to further analyze tissue-specific gene expression programs. These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.

MES-4, an autosome-associated HMT that participates in silencing the X chromosomes in the C. elegans germ line

Project description:Microarray-based expression profiling of dissected gonads from mes-4 mutants reveals that MES-4 is required to repress expression of a set of X-linked genes. We isolated dissected gonads from mes-4(bn85) mutant adults and compared to dissected gonads from wild type (N2 animals. RNA was linearly amplified prior to labeling for all genotypes. Comparison was done in quadruplicate on independently grown and isolated animals.

Promotion of oogenesis and embryogenesis in the C. elegans gonad by EFL-1/DPL-1(E2F)does not require LIN-35(pRB)

Project description:Microarray-based expression profiling of dissected gonads from efl-1, dpl-1 and lin-35 mutants reveals that EFL-1 and DPL-1 promote expression of an extensively overlapping set of target genes, consistent with the expectation that these two proteins function as a heterodimer. Regulatory regions upstream of many of these target genes have a canonical E2F binding site, suggesting that their regulation by EFL-1/DPL-1 is direct. Many EFL-1/DPL-1 responsive genes encode proteins required for oogenesis and early embryogenesis, rather than cell cycle components. By contrast, LIN-35 appears to function primarily as a repressor of gene expression in the germ line, and the genes that it acts on are for the most part distinct from those regulated by EFL-1 and/or DPL-1 We isolated dissected gonads from dpl-1, efl-1 and lin-35 mutant adults and compared each to control dissected gonads. RNA was linearly amplified prior to labeling for all genotypes. Each comparison was done in triplicate (dpl-1 and lin-35) or in quadruplicate (efl-1) on independently grown and isolated animals.

DEPS-1 promotes P granule assembly and RNA interference in C. elegans germ cells

Project description:P granules are germ-cell-specific cytoplasmic structures containing RNA and protein and required for proper germ cell development in C. elegans. A new P-granule-associated protein, DEPS-1, whose loss disrupts P granule structure and function was analysed in this study. Genome wide analysis of gene expression in deps-1 mutant germ lines identified additional targets of DEPS-1 regulation, many of which are also regulated by the RNAi factor RDE-3. Our studies suggest that DEPS-1 is a key component of the P granule assembly pathway and that its roles include promoting accumulation of some mRNAs, such as glh-1 and rde-4, and reducing accumulation of other mRNAs, perhaps by collaborating with RDE-3 to generate endogenous short interfering RNAs (endo-siRNAs). We isolated dissected gonads from deps-1 mutant adults and compared each to wild type dissected gonads. RNA was linearly amplified prior to labeling for all genotypes. The comparisons were done in quadruplicate on independently grown and isolated animals.
