In this study, RBM5 and RBM10 were examined in non-transformed cells in order to gain a wider range of knowledge regarding their function. Expression of Rbm5 and Rbm10, as well as select splice variants, was examined at the mRNA and protein level throughout H9c2 skeletal and cardiac myoblast differentiation. Results suggest that Rbm5 and Rbm10 may (a) be involved in regulating cell cycle arrest and apoptosis during skeletal myoblast differentiation and (b) undergo post-transcriptional or translational regulation throughout myoblast differentiation. All in all, the expression profiles obtained in the course of this study will help to suggest a role for Rbm5 and Rbm10 in differentiation, as well as possible differentiation-specific target genes with which they may interact.

The LUCA-15 gene locus encodes at least four alternatively spliced transcripts, which have been shown to function as regulators of apoptosis, a fact that may have a major significance in tumour regulation. This review highlights evidence that implicates the LUCA-15 locus in the control of apoptosis and cell proliferation, and reports observations that significantly strengthen the case for tumour suppressor activity by this gene. KEY WORDS: T-lymphocytes, LUCA-15, RNA-binding proteins, cell death, cell proliferation DOMAINS: cell death, cell cycle, oncology, gene regulation INTRODUCTION The molecular control of cancer is complex. Cancer genes are involved in the dysregulation of a whole range of normal cellular systemic processes including cell proliferation[1], cell-cell communication[2], DNA repair[3], chromosome stability[4], tumour invasion, motility and metastasis[5,6], apoptosis[7], and others. Despite impressive progress in recent years in understanding the molecular basis of cancer, many crucial genes remain to be identified.

  • Supplemental Information Figure S1. Genome-Wide Alternative Splicing
    Supplemental information Figure S1. Genome-wide alternative splicing events affected by inducible expression SRSF3 in mouse MEF3T3 cells. To examine the effects of SRSF3 (SRp20) on genome-wide RNA splicing in mouse cells, we utilized Exonhit SpliceArray to compare genome-wide changes of RNA splicing and transcription in MEF3T3 mouse fibroblasts with or without ectopically inducible expression of SRp20. (A–C) Clustered heat maps for the top events regulated by SRSF3 identified by ExonHit splice arrays. SRSF3-targeted genes in three experimental repeats consist of 65 evidenced splicing events (A), 74 novel splicing events (B) and 11 genes with expression changes (C), with a threshold of ≥2-fold changes (p<0.01) in log2 as determined by a B/E method and FDR cutoff of 0.1 for gene expression change and 0.2 for splicing alternation. Individual gene names and event ID are indicated on the right. Event ID specifies individual splicing events being detailed in Supplementary Table S1-S3. MEF3T3 cells with an empty vector transfection were included as vector controls. Color key scales in log2 values are indicated at the bottom of each panel.

  • Insight Into the Role of Alternative Splicing Within the Rbm10v1 Exon 10 Tandem Donor Site
    Tessier et al. BMC Research Notes (2015) 8:46 DOI 10.1186/s13104-015-0983-5 SHORT REPORT Open Access Insight into the role of alternative splicing within the RBM10v1 exon 10 tandem donor site Sarah J Tessier1, Julie J Loiselle2, Anne McBain3, Celine Pullen1, Benjamin W Koenderink4, Justin G Roy5 and Leslie C Sutherland1,2,4,5,6,7* Abstract Background: RBM10 is an RNA binding protein involved in the regulation of transcription, alternative splicing and message stabilization. Mutations in RBM10, which maps to the X chromosome, are associated with TARP syndrome, lung and pancreatic cancers. Two predominant isoforms of RBM10 exist, RBM10v1 and RBM10v2. Both variants have alternate isoforms that differ by one valine residue, at amino acid 354 (RBM10v1) or 277 (RBM10v2). It was recently observed that a novel point mutation at amino acid 354 of RBM10v1, replacing valine with glutamic acid, correlated with preferential expression of an exon 11 inclusion variant of the proliferation regulatory protein NUMB, which is upregulated in lung cancer. Findings: We demonstrate, using the GLC20 male-derived small cell lung cancer cell line - confirmed to have only one X chromosome - that the two (+/−) valine isoforms of RBM10v1 and RBM10v2 result from alternative splicing. Protein modeling of the RNA Recognition Motif (RRM) within which the alteration occurs, shows that the presence of valine inhibits the formation of one of the two α-helices associated with RRM tertiary structure, whereas the absence of valine supports the α-helical configuration. We then show 2-fold elevated expression of the transcripts encoding the minus valine RBM10v1 isoform in GLC20 cells, compared to those encoding the plus valine isoform.

    www.nature.com/scientificreports OPEN OncoScore: a novel, Internet- based tool to assess the oncogenic potential of genes Received: 06 July 2016 Rocco Piazza1, Daniele Ramazzotti2, Roberta Spinelli1, Alessandra Pirola3, Luca De Sano4, Accepted: 15 March 2017 Pierangelo Ferrari3, Vera Magistroni1, Nicoletta Cordani1, Nitesh Sharma5 & Published: 07 April 2017 Carlo Gambacorti-Passerini1 The complicated, evolving landscape of cancer mutations poses a formidable challenge to identify cancer genes among the large lists of mutations typically generated in NGS experiments. The ability to prioritize these variants is therefore of paramount importance. To address this issue we developed OncoScore, a text-mining tool that ranks genes according to their association with cancer, based on available biomedical literature. Receiver operating characteristic curve and the area under the curve (AUC) metrics on manually curated datasets confirmed the excellent discriminating capability of OncoScore (OncoScore cut-off threshold = 21.09; AUC = 90.3%, 95% CI: 88.1–92.5%), indicating that OncoScore provides useful results in cases where an efficient prioritization of cancer-associated genes is needed. The huge amount of data emerging from NGS projects is bringing a revolution in molecular medicine, leading to the discovery of a large number of new somatic alterations that are associated with the onset and/or progression of cancer. However, researchers are facing a formidable challenge in prioritizing cancer genes among the variants generated by NGS experiments. Despite the development of a significant number of tools devoted to cancer driver prediction, limited effort has been dedicated to tools able to generate a gene-centered Oncogenic Score based on the evidence already available in the scientific literature.

An OCRE (OCtamer REpeat of aromatic residues) domain found in RBM5 is important for alternative splicing regulation and mediates interactions with components of the U4/U6.U5 tri-snRNP. We show that the RBM5 OCRE domain adopts a unique b–sheet fold. NMR and biochemical experiments demonstrate that the OCRE domain directly binds to the proline-rich C-terminal tail of the essential snRNP core proteins SmN/B/B’.
