3' RACE-seq of reporter LINE-1 and control mRNAs' 3' non-templated ends in 293T 'wild-type', XRN1 KO, DCP2 KO, DCP2 plus XRN1 KO cells

ABSTRACT: Human LINE-1 retrotransposons can mobilize in the human genome by a copy-and-paste machanism involving RNA intermediates. LINE-1 mRNA 3' ends play a major role in initiation of reverse transcription (a step retrotransposition). To assess the impact of RNA 3’ end dynamics of LINE-1 mRNA on its retrotransposition potential in human cells we analyzed 3' non-templated ends on LINE-1, and control GAPDH and PABPC4 mRNAs by 3' RACE-seq. RNA was retrieved from multiple clonal 293T cells wild-type or knock-out in eitehr XRN1, DCP2, or both (DCP2 plus XRN1).

Transcription profiling of yeast wild type, xrn1, xrn1 upf1, xrn1 nmd2, and xrn1 upf3 strains to investigate mRNA decay

Project description:To determine the effects of inactivation of both the nosense-mediated mRNA decay pathway and the general 5' to 3' decay pathway on yeast mRNA decay, we compared the expression profiles of the wild-type, xrn1, xrn1 upf1, xrn1 nmd2, and xrn1 upf3 strains.

Gene expression is a circular process

Project description:This study involves the role of yeast mRNA decay factors in transcription. The experiment included here are the ChIP-exo results of three decay factors: Xrn1, Dcp2 & Lsm1. Four experiments were made: Xrn1, Dcp2, Lsm1 and control (no-TAP tag), in two replicates.

Effects of Dcp1a and Dcp2 knockdown during mouse oocyte maturation

Project description:Oocyte maturation is accompanied by a transition from mRNA stability to instability. We investigated the role of DCP1A and DCP2, proteins responsible for mRNA decapping, in mRNA destabilization during mouse oocyte maturation. siRNA-mediated knockdown of both Dcp1a and Dcp2 transcripts prior to initiation of maturation inhibited the maturation-associated increase of DCP1A and DCP2, stabilized a set of maternal mRNAs that are normally degraded during maturation, and inhibited development beyond the 2-cell stage, likely a consequence of failure to activate fully the zygotic genome. Total RNA from 30 MII eggs was used in each sample. Three independent biological replicates were analyzed for each condition.

Global analysis of mRNA decay intermediates in Saccharomyces cerevisiae

Project description:The general pathways of eukaryotic mRNA decay occur via deadenylation followed by 3’ to 5’ degradation or decapping, although some endonuclease sites have been identified in metazoan mRNAs. To determine the role of endonucleases in mRNA degradation in Saccharomyces cerevisiae, we mapped 5’ monophosphate ends on mRNAs in wild-type and dcp2∆ xrn1∆ yeast cells, wherein mRNA endonuclease cleavage products are stabilized. This led to three important observations. First, only few mRNAs that undergo low level endonucleotyic cleavage were observed suggesting that endonucleases are not a major contributor to yeast mRNA decay. Second, independent of known decapping enzymes, we observed low levels of 5’ monophosphates on some mRNAs suggesting that an unknown mechanism can generate 5' exposed ends, although for all substrates tested Dcp2 was the primary decapping enzyme. Finally, we identified debranched lariat intermediates from intron-containing genes, demonstrating a significant discard pathway for mRNAs during the second step of pre-mRNA splicing, which is a potential new step to regulate gene expression. 5' monophosphorylated ends of poly(A) RNA from wild-type and dcp2D xrn1D strains were identified in duplicates and triplicates, respectively.
