Mouse Rbm7 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Rbm7 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Rbm7 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Rbm7 gene (NCBI Reference Sequence: NM_144948 ; Ensembl: ENSMUSG00000042396 ) is located on Mouse chromosome 9. 5 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 5 (Transcript: ENSMUST00000170000). Exon 4 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Rbm7 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-147I23 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 4 starts from about 43.77% of the coding region. The knockout of Exon 4 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 2468 bp, and the size of intron 4 for 3'-loxP site insertion: 859 bp. The size of effective cKO region: ~627 bp. The cKO region does not have any other known gene.

No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

However, the role of this process in human disease, and particularly in cancer, is only starting to be unveiled. We system- atically analyzed mutation, copy number, and gene expression patterns of 1348 RNA-binding protein (RBP) genes in 11 solid tumor types, together with alternative splicing changes in these tumors and the enrichment of binding motifs in the alter- natively spliced sequences. Our comprehensive study reveals widespread alterations in the expression of RBP genes, as well as novel mutations and copy number variations in association with multiple alternative splicing changes in cancer drivers and oncogenic pathways. Remarkably, the altered splicing patterns in several tumor types recapitulate those of undifferen- tiated cells. These patterns are predicted to be mainly controlled by MBNL1 and involve multiple cancer drivers, including the mitotic gene NUMA1. We show that NUMA1 alternative splicing induces enhanced cell proliferation and centrosome am- plification in nontumorigenic mammary epithelial cells.

  • Structural Basis for MTR4–ZCCHC8 Interactions That Stimulate the MTR4 Helicase in the Nuclear Exosome-Targeting Complex
    Structural basis for MTR4–ZCCHC8 interactions that stimulate the MTR4 helicase in the nuclear exosome-targeting complex M. Rhyan Punoa,b and Christopher D. Limaa,b,1 aStructural Biology Program, Sloan Kettering Institute, New York, NY 10065; and bHoward Hughes Medical Institute, Sloan Kettering Institute, New York, NY 10065 Edited by Lynne E. Maquat, University of Rochester School of Medicine and Dentistry, Rochester, NY, and approved May 9, 2018 (received for review February 27, 2018) The nuclear exosome-targeting (NEXT) complex functions as an complex (PPC) (17). NEXT is a nucleoplasmic ternary complex RNA exosome cofactor and is involved in surveillance and turnover consisting of RBM7, ZCCHC8, and MTR4 (15). RBM7 is a of aberrant transcripts and noncoding RNAs. NEXT is a ternary 31-kDa protein with a polyuridine-specific RNA recognition motif complex composed of the RNA-binding protein RBM7, the scaffold (RRM) (18), while the zinc-knuckle protein ZCCHC8 acts as a zinc-knuckle protein ZCCHC8, and the helicase MTR4. While RNA scaffold, mediating the interaction between RBM7 and MTR4 (16). interactions with RBM7 are known, it remains unclear how NEXT NEXT is involved in exosome-mediated surveillance and decay of subunits collaborate to recognize and prepare substrates for degra- noncoding RNAs, such as enhancer RNAs (eRNAs) and aberrant dation. Here, we show that MTR4 helicase activity is enhanced when 3′-extended transcripts from small nuclear RNA (snRNA), telo- associated with RBM7 and ZCCHC8. While uridine-rich substrates merase RNA, and replication-dependent histone genes (15, 19, 20). interact with RBM7 and are preferred, optimal activity is observed It ensures a unidirectional output from pervasive transcription of ′ when substrates include a polyadenylated 3 end.

Academic Editors: Wolf-Dietrich Heyer, Thomas Helleday and Fumio Hanaoka Received: 12 August 2015 / Accepted: 16 October 2015 / Published: 29 October 2015 Abstract: The number of factors known to participate in the DNA damage response (DDR) has expanded considerably in recent years to include splicing and alternative splicing factors. While the binding of splicing proteins and ribonucleoprotein complexes to nascent transcripts prevents genomic instability by deterring the formation of RNA/DNA duplexes, splicing factors are also recruited to, or removed from, sites of DNA damage. The first steps of the DDR promote the post-translational modification of splicing factors to affect their localization and activity, while more downstream DDR events alter their expression. Although descriptions of molecular mechanisms remain limited, an emerging trend is that DNA damage disrupts the coupling of constitutive and alternative splicing with the transcription of genes involved in DNA repair, cell-cycle control and apoptosis. A better understanding of how changes in splice site selection are integrated into the DDR may provide new avenues to combat cancer and delay aging.

Here we show the overexpression of micro-RNAs 132 and 212 enhances insulin secretion (IS) in response to glucose and other secretagogues including non-fuel stimuli. We determined that carnitine acyl-carnitine translocase (CACT, Slc25a20) is a direct target of these miRNAs.

    Resource On the Relationship of Protein and mRNA Dynamics in Vertebrate Embryonic Development Graphical Abstract Authors Leonid Peshkin, Martin Wu¨ hr, Esther Pearl, ..., Marko Horb, Steven P. Gygi, Marc W. Kirschner Correspondence [email protected] (S.P.G.), [email protected] (M.W.K.) In Brief Embryos express proteins at the correct time during development, by balancing the maternal contribution with protein synthesis and degradation. Peshkin et al. determine the absolute concentrations of 10,000 proteins and 28,000 transcripts across Xenopus development, uncovering the relative roles of these three processes across the proteome and revealing global trends.

Esta pomposa frase resume lo que estos años de tesis doctoral me han aportado como investigadora: una inconmensurable resistencia al fracaso y toneladas de pragmatismo. Con esto quiero comenzar a dar las gracias a Marian Martínez-Balbás, por haberme formado en competencias científicas y en competencias transversales como la idiosincrasia de la ciencia y sus científicos. El hecho de que no me pueda imaginar dedicándome a otra cosa en el futuro te lo debo en gran medida a ti. Gracias por las discusiones regadas con café (quizás más café del que deberíamos) y por no estar siempre de acuerdo conmigo.

  • Somatic Reversion Impacts Evolution of Myelodysplastic Syndromes and Acute Myeloid Leukemia in the Short Telomere Disorders

BACKGROUND. Germline mutations in telomerase and other telomere maintenance genes manifest in the premature aging short telomere syndromes. Myelodysplastic syndromes and acute myeloid leukemia (MDS/AML) account for 75% of associated malignancies, but how these cancers overcome the inherited telomere defect is unknown. METHODS. We used ultra-deep targeted sequencing to detect somatic reversion mutations in 17 candidate telomere lengthening genes among controls and patients with short telomere syndromes with and without MDS/AML, and we tested the functional significance of these mutations. RESULTS. While no controls carried somatic mutations in telomere maintenance genes, 29% (16 of 56) of adults with germline telomere maintenance defects carried at least 1 (P < 0.001), and 13% (7 of 56) had 2 or more. In addition to TERT promoter mutations, which were present in 19%, another 13% of patients carried a mutation in POT1 or TERF2IP. POT1 mutations impaired telomere binding in vitro and some mutations were identical to ones seen in familial melanoma associated with longer telomere length.

Whereas NEAT1_2 is (lncRNA).

Extensive RNAi analyses of specific organs. Paraspeckle formation is initiated by transcription 40 paraspeckle proteins (PSPs) revealed that seven PSPs, namely of the NEAT1 chromosomal locus and proceeds in conjunction with heterogeneous nuclear RNP K (HNRNPK), NONO, RNA- NEAT1 lncRNA biogenesis and a subsequent assembly step involv- binding motif protein 14 (RBM14), SFPQ, DAZ-associated ing >40 paraspeckle proteins (PSPs).
