Mouse Rbms1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Rbms1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Rbms1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Rbms1 gene (NCBI Reference Sequence: NM_020296 ; Ensembl: ENSMUSG00000026970 ) is located on Mouse chromosome 2. 14 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 13 (Transcript: ENSMUST00000028347). Exon 3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Rbms1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-172B13 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: Only about half the expected number of mice homozygous for disruptions in this gene are produced in matings of heterozygotes. Embryo sizes are reduced. Females have smaller than normal uteri and decreased levels of progesterone during estrus. Exon 3 starts from about 20.84% of the coding region. The knockout of Exon 3 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 44554 bp, and the size of intron 3 for 3'-loxP site insertion: 4903 bp. The size of effective cKO region: ~559 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.

Current algorithms do not sufficiently identify false-positive fusions arising during library preparation, sequencing, and alignment. Here, we introduce a new algorithm, DEEPEST, that uses statistical modeling to minimize false-positives while increasing the sensitivity of fusion detection. In 9,946 tumor RNA-sequencing datasets from The Cancer Genome Atlas (TCGA) across 33 tumor types, DEEPEST identifies 31,007 fusions, 30% more than identified by other methods, while calling ten-fold fewer false-positive fusions in non-transformed human tissues. We leverage the increased precision of DEEPEST to discover new cancer biology. For example, 888 new candidate oncogenes are identified based on over-representation in DEEPEST-Fusion calls, and 1,078 previously unreported fusions involving long intergenic noncoding RNAs partners, demonstrating a previously unappreciated prevalence and potential for function.

Abstract: The number of patients with neurodegenerative diseases (NDs) is increasing, along with the growing number of older adults. This escalation threatens to create a medical and social crisis. NDs include a large spectrum of heterogeneous and multifactorial pathologies, such as amyotrophic lateral sclerosis, frontotemporal dementia, Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and multiple system atrophy, and the formation of inclusion bodies resulting from protein misfolding and aggregation is a hallmark of these disorders. The proteinaceous components of the pathological inclusions include several RNA-binding proteins (RBPs), which play important roles in splicing, stability, transcription and translation. In addition, RBPs were shown to play a critical role in regulating miRNA biogenesis and metabolism. The dysfunction of both RBPs and miRNAs is Citation: Kinoshita, C.; Kubota, N.; often observed in several NDs. Thus, the data about the interplay among RBPs and miRNAs and Aoyama, K.

Lluis Companys 23, Barcelona 08010, Spain *Corresponding authors: Luciano Di Croce ([email protected]) Sergi Aranda ([email protected]) 1 GRAPHICAL ABSTRACT Chromatin-bound proteins regulate gene expression, replicate and repair DNA, and transmit epigenetic information. Several human diseases are highly influenced by alterations in the chromatin- bound proteome. Thus, biochemical approaches for the systematic characterization of the chromatome could contribute to identifying new regulators of cellular functionality, including those that are relevant to human disorders. 2 SUMMARY Chromatin-bound proteins underlie several fundamental cellular functions, such as control of gene expression and the faithful transmission of genetic and epigenetic information. Components of the chromatin proteome (the “chromatome”) are essential in human life, and mutations in chromatin-bound proteins are frequently drivers of human diseases, such as cancer. Proteomic characterization of chromatin and de novo identification of chromatin interactors could thus reveal important and perhaps unexpected players implicated in human physiology and disease. Recently, intensive research efforts have focused on developing strategies to characterize the chromatome composition. In this review, we provide an overview of the dynamic composition of the chromatome, highlight the importance of its alterations as a driving force in human disease (and particularly in cancer), and discuss the different approaches to systematically characterize the chromatin-bound proteome in a global manner.

  • Transcriptomic Response of Breast Cancer Cells to Anacardic Acid David J
    www.nature.com/scientificreports OPEN Transcriptomic response of breast cancer cells to anacardic acid David J. Schultz1, Abirami Krishna2, Stephany L. Vittitow2, Negin Alizadeh-Rad2, Penn Muluhngwi2, Eric C. Rouchka 3 & Carolyn M. Klinge 2 Received: 5 December 2017 Anacardic acid (AnAc), a potential dietary agent for preventing and treating breast cancer, inhibited Accepted: 10 May 2018 the proliferation of estrogen receptor α (ERα) positive MCF-7 and MDA-MB-231 triple negative Published: xx xx xxxx breast cancer cells. To characterize potential regulators of AnAc action, MCF-7 and MDA-MB-231 cells were treated for 6 h with purifed AnAc 24:1n5 congener followed by next generation transcriptomic sequencing (RNA-seq) and network analysis. We reported that AnAc-diferentially regulated miRNA transcriptomes in each cell line and now identify AnAc-regulated changes in mRNA and lncRNA transcript expression. In MCF-7 cells, 80 AnAc-responsive genes were identifed, including lncRNA MIR22HG. More AnAc-responsive genes (886) were identifed in MDA-MB-231 cells. Only six genes were commonly altered by AnAc in both cell lines: SCD, INSIG1, and TGM2 were decreased and PDK4, GPR176, and ZBT20 were increased. Modeling of AnAc-induced gene changes suggests that AnAc inhibits monounsaturated fatty acid biosynthesis in both cell lines and increases endoplasmic reticulum stress in MDA-MB-231 cells. Since modeling of downregulated genes implicated NFκB in MCF-7, we confrmed that AnAc inhibited TNFα-induced NFκB reporter activity in MCF-7 cells. These data identify new targets and pathways that may account for AnAc’s anti-proliferative and pro-apoptotic activity.

Abstract Gestational diabetes mellitus (GDM) is one of the metabolic diseases during pregnancy. The identification of the central molecular mechanisms liable for the disease pathogenesis might lead to the advancement of new therapeutic options. The current investigation aimed to identify central differentially expressed genes (DEGs) in GDM. The transcription profiling by array data (E-MTAB-6418) was obtained from the ArrayExpress database. The DEGs between GDM samples and non GDM samples were analyzed with limma package. Gene ontology (GO) and REACTOME enrichment analysis were performed using ToppGene. Then we constructed the protein-protein interaction (PPI) network of DEGs by the Search Tool for the Retrieval of Interacting Genes database (STRING) and module analysis was performed.

  • RNA Binding Proteins As Drivers and Therapeutic Target Candidates in Pancreatic Ductal Adenocarcinoma
    International Journal of Molecular Sciences Article RNA Binding Proteins as Drivers and Therapeutic Target Candidates in Pancreatic Ductal Adenocarcinoma Markus Glaß 1,* , Patrick Michl 2 and Stefan Hüttelmaier 1 1 Institute of Molecular Medicine, Martin Luther University Halle-Wittenberg, Charles Tanford Protein Center, Kurt-Mothes-Str. 3a, 06120 Halle, Germany; [email protected] 2 Universitätsklinik und Poliklinik für Innere Medizin I, Universitätsklinikum Halle (Saale), Ernst-Grube-Str. 40, 06120 Halle (Saale), Germany; [email protected] * Correspondence: [email protected] Received: 8 May 2020; Accepted: 8 June 2020; Published: 11 June 2020 Abstract: Pancreatic ductal adenocarcinomas (PDAC) belong to the most frequent and most deadly malignancies in the western world. Mutations in KRAS and TP53 along with some other frequent polymorphisms occur almost universally and are likely to be responsible for tumor initiation. However, these mutations cannot explain the heterogeneity in therapeutic responses observed in PDAC patients, which limits efficiency of current therapeutic strategies. Instead, recent classifications of PDAC tumor samples are based on transcriptomics data and thus include information about epigenetic, transcriptomic, and post-transcriptomic deregulations. RNA binding proteins (RBPs) are important post-transcriptional regulators involved in every aspect of the RNA life cycle and thus considerably influence the transcriptome. In this study, we systematically investigated deregulated expression, prognostic value, and essentiality reported for RBPs in PDAC or PDAC cancer models using publicly available data. We identified 44 RBPs with suggested oncogenic potential. These include various proteins, e.g., IGF2 mRNA binding proteins (IGF2BPs), with reported tumor-promoting roles. We further characterized these RBPs and found common patterns regarding their expression, interaction, and regulation by microRNAs.
