The Nrd1-like protein Seb1 coordinates co-transcriptional 3â end processing and polyadenylation site selection

Project description:Termination of RNAPII transcription is associated with RNA 3â end formation. For coding genes, termination is initiated by the cleavage/polyadenylation machinery. In contrast, a majority of noncoding transcription events in S. cerevisiae do not rely on RNA cleavage for termination, but instead terminate via a pathway that requires the Nrd1-Nab3-Sen1 (NNS) complex. Here we show that the S. pombe ortholog of Nrd1, Seb1, does not function in NNS-like termination, but promotes polyadenylation site selection of coding and noncoding genes. We found that Seb1 associates with 3â end processing factors, is enriched at the 3â end of genes, and binds RNA motifs downstream of cleavage sites. Importantly, a deficiency in Seb1 resulted in widespread changes in 3â UTR length as a consequence of increased alternative polyadenylation. Given that Seb1 levels affected the recruitment of conserved 3â end processing factors, our findings indicate that the conserved RNA-binding protein Seb1 co-transcriptionally controls alternative polyadenylation. Two biological replicates of Seb1 and Control (parental strain) CRAC experiments

Genome-wide analysis of Prz1 in fission yeast reveals a novel inhibitory role in flocculation and a conserved activating role in cell wall organization [ChIP-chip]

Project description:Gene regulation in response to intracellular calcium is mediated by the calcineurin-activated transcription factor Prz1 in the fission yeast Schizosaccharomyces pombe. Genome-wide studies of the Crz1 and CrzA fungal orthologs have uncovered numerous target genes involved in conserved and species-specific cellular processes. In contrast, very few target genes of Prz1 have been published. This paper identified an extensive list of genes using transcriptome and ChIP-chip analyses under inducing conditions of Prz1, including CaCl2, and tunicamycin treatment, as well as a â??pmr1 genetic background. We identified 165 upregulated putative target genes of Prz1 in which the majority contained a calcium-dependent response element in their promoters, similar to that of the Saccharomyces cerevisiae ortholog Crz1. These genes were functionally enriched for Crz1-conserved processes such as cell wall biosynthesis. Overexpression of prz1+ increased resistance to the cell wall degradation enzyme zymolyase, likely from upregulation of the O-mannosyltransferase encoding gene omh1+. Loss of omh1+ abrogates this phenotype. We uncovered a novel inhibitory role in flocculation for Prz1. Loss of prz1+ resulted in constitutive flocculation and upregulation of genes encoding the flocculins Gsf2 and Pfl3, as well as the transcription factor Cbf12. The constitutive flocculation of the â??prz1 strain was abrogated by the loss of gsf2+ or cbf12+. This study reveals that Prz1 functions as a positive and negative transcriptional regulator of genes involved in cell wall biosynthesis and flocculation, respectively. Moreover, comparison of target genes between Crz1/CrzA and Prz1 indicate some conservation in DNA-binding specificity, but also substantial rewiring of the calcineurin-mediated transcriptional-regulatory network. We generated 2 ChIP-chip experiments, each with a biological replicate performed as a dye swap.

Genome-wide analysis of gene expression in TM4 Sertoli cells following siRNA-mediated Gata4 inhibition

Project description:The effects of Gata4 inhibition on global gene expression in TM4 Sertoli cells was analyzed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Leydig tumor cell line mLTC-1. Among the downregulated genes were enzymes of the androgen biosynthetic pathway. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted. n=3 of each sample group; control samples are samples 3-6 (TM4 cells treated with non-targeting siRNA)

Loss of Cardiac microRNA-Mediated Regulation Leads to Dilated Cardiomyopathy and Heart Failure.

Project description:RATIONALE: Heart failure is a deadly and devastating disease that places immense costs on an aging society. To develop therapies aimed at rescuing the failing heart, it is important to understand the molecular mechanisms underlying cardiomyocyte structure and function. OBJECTIVE: microRNAs are important regulators of gene expression, and we sought to define the global contributions made by microRNAs toward maintaining cardiomyocyte integrity. METHODS AND RESULTS: First, we performed deep sequencing analysis to catalog the miRNA population in the adult heart. Second, we genetically deleted, in cardiac myocytes, an essential component of the machinery that is required to generate miRNAs. Deep sequencing of miRNAs from the heart revealed the enrichment of a small number of microRNAs with one, miR-1, accounting for 40% of all microRNAs. Cardiomyocyte-specific deletion of dgcr8, a gene required for microRNA biogenesis, revealed a fully penetrant phenotype that begins with left ventricular malfunction progressing to a dilated cardiomyopathy and premature lethality. CONCLUSIONS: These observations reveal a critical role for microRNAs in maintaining cardiac function in mature cardiomyocytes and raise the possibility that only a handful of microRNAs may ultimately be responsible for the dramatic cardiac phenotype seen in the absence of dgcr8. We report the miRNA composition of 6-8 week old murine heart. We performed deep sequencing analysis to catalog the miRNA population in the adult heart. 2 sample were sequenced.
