Gene expression signatures of primary and metastatic uterine leiomyosarcoma.
Oslo, Norway. In Hum Pathol, 30 Apr 2014
Genes overexpressed in primary uterine LMSs included OSTN, NLGN4X, NLGN1, SLITRK4, MASP1, XRN2, ASS1, RORB, HRASLS, and TSPAN7.
The multifunctional RNase XRN2.
Basel, Switzerland. In Biochem Soc Trans, Aug 2013
XRN2 is a 5'→3' exoribonuclease that is evolutionarily conserved in eukaryotes.
Co-transcriptional degradation of aberrant pre-mRNA by Xrn2.
Edinburgh, United Kingdom. In Embo J, 2012
Xrn2 associated with and co-transcriptionally degraded nascent beta-globin transcripts. Evidence was provided that many endogenous pre-mRNAs are also co-transcriptionally degraded by Xrn2 when their processing is inhibited by Spliceostatin A.
MicroRNAses and the regulated degradation of mature animal miRNAs.
Basel, Switzerland. In Adv Exp Med Biol, 2009
Initially thought to be very stable with half-lives on the order of days, mature miRNAs have recently been shown to be subject to degradation by 'microRNases' (miRNases) in plants (the small RNA degrading nucleases, SDN) and animals (exoribonuclease 2/XRN-2/XRN2).
Turnover of mature miRNAs and siRNAs in plants and algae.
Lincoln, United States. In Adv Exp Med Biol, 2009
Recent studies in Arabidopsis thaliana and Caenorhabditis elegans have implicated 3'-to-5' (SDNs) and 5'-to-3' (XRN-2) exoribonucleases in mature miRNA turnover and the modulation of small RNA levels and activity.
A ribonucleolytic rat torpedoes RNA polymerase II.
Aurora, United States. In Cell, 2005
Three recent papers reveal a fascinating link between pol II termination and ribonucleolytic decay of the nascent transcript by a 5'-3' exonuclease (yeast Rat1 and human Xrn2).
