Project description:Translational control is critical for early Drosophila embryogenesis and is exerted mainly at the gene-specific level. To understand the post-transcriptional regulation during Drosophila early embryonic development, we used the sucrose polysomal gradient analyses and GeneChip analysis to illustrate the translation profile of individual mRNAs. A paper was published in Genome Biology 2007 under the tile Global analyses of mRNA translational control during early Drosophila embryogenesis". Experiment Overall Design: In this study, we have fractionated embryo extracts from a series of early stages by sedimentation on sucrose density gradients and analyzed the RNA components of these fractions. Our analysis has focused on analyzing ribosomal density, generally and for individual transcripts, global translational activity during the first 10 hours after egg laying and coordination between transcription and translation regulation.

Project description:Protein post-translational modifications transmit signals in part by creating binding sites for effector molecules. This is especially true in epigenetic pathways where histone tails are heavily modified, resulting in the recruitment of molecules that can affect transcription. One such molecule, plant homeodomain finger protein 20 (PHF20), uses a Tudor domain to read dimethyl-lysine residues and is a known component of the MOF histone acetyltransferase protein complex, suggesting it plays a role in the crosstalk between lysine methylation and histone acetylation. We sought to investigate the biological role of PHF20 by generating a knockout mouse. Without PHF20, mice die shortly after birth and display a wide variety of phenotypes within the skeletal and hematopoietic systems. Mechanistically, PHF20 is not required for maintaining the global H4K16 acetylation levels, but instead works downstream in transcriptional regulation of MOF target genes.

Project description:We report genome-wide characterization of GATA3 binding sites in eleven well-defined developmental and effector cell types of the T lymphocyte lineage. By utilizing a conditional allele of GATA3, we investigated the impact of GATA3 expression on the mRNA expression patterns in several of these cell types. Correlation of GATA3 binding with gene expression changes indicates that GATA3 regulates a large number of stage- and cell-specific genes involved in multiple signaling and transcriptional pathways critical for T cell differentiation and immune responses. 1) RNA-Seq: Examination of RNA transcript levels in 6 cell types in wild-type and Gata3-knockout cells. 2) ChIP-Seq: Examination of GATA3 binding sites in 11 cell types. 3) Methyl-Seq: Examination of histone modification levels in DP cells from wild-type and Gata3-knockout mice.

Project description:Estrogen receptor alpha (ERα) activity is associated with increased cancer cell proliferation. Studies aiming to understand the impact of ERα on cancer-associated phenotypes have largely been limited to its transcriptional activity. Herein, we demonstrate that ERα coordinates its transcriptional output with selective modulation of mRNA translation. Importantly, translational perturbations caused by depletion of ERα largely manifest as "translational offsetting" of the transcriptome, whereby amounts of translated mRNAs and corresponding protein levels are maintained constant despite changes in mRNA abundance. Transcripts whose levels, but not polysome-association, are reduced following ERα depletion lack features which limit translation efficiency including structured 5'UTRs and miRNA target sites. In contrast, mRNAs induced upon ERα depletion whose polysome-association remains unaltered are enriched in codons requiring U34-modified tRNAs for efficient decoding. Consistently, ERα regulates levels of U34-modifying enzymes and thereby controls levels of U34-modified tRNAs. These findings unravel a hitherto unprecedented mechanism of ERα-dependent orchestration of transcriptional and translational programs that may be a pervasive mechanism of proteome maintenance in hormone-dependent cancers.
