Mouse Cnot9 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Cnot9 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Cnot9 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Cnot9 gene (NCBI Reference Sequence: NM_021383.5 ; Ensembl: ENSMUSG00000026174 ) is located on Mouse chromosome 1. 8 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 8 (Transcript: ENSMUST00000087215). Exon 2~3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Cnot9 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-70H11 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: Embryos homozygous for an ENU-induced allele exhibit abnormal nervous system and brain morphology, cranioedema, and caudal body truncation. Mice carrying a targeted allele exhibit embryonic lethality. Exon 2 starts from about 2.79% of the coding region. The knockout of Exon 2~3 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 10608 bp, and the size of intron 3 for 3'-loxP site insertion: 3301 bp. The size of effective cKO region: ~2447 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8947bp) | A(26.96% 2412) | C(20.79% 1860) | T(31.89% 2853) | G(20.36% 1822) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Geschwind, Chair Neuropsychiatric disorders are behavioral conditions marked by intellectual, social, or emotional deficits that can be linked to diseases of the nervous system. Autism spectrum disorder (ASD), schizophrenia (SCZ), bipolar disorder (BP), major depressive disorder (MDD), and attention deficit and hyperactivity disorder (ADHD) are common, heritable diseases each with a prevalence exceeding 1% of the population, none of which can be characterized by discernable anatomical or neurological pathologies. Genetic association studies have identified mutations in hundreds of genes that contribute to risk for at least one of these disorders, and have shown that a substantial fraction of the genetic liability is shared between many of these neuropsychiatric diseases. It has long been hoped that with enough genetic evidence we will identify the biological pathways, developmental time points, and brain regions that, when disrupted, give rise to neuropsychiatric disorders.

    Regulation of gene silencing: From microRNA biogenesis to post-translational modifications of TNRC6 complexes DISSERTATION zur Erlangung des DOKTORGRADES DER NATURWISSENSCHAFTEN (Dr. rer. nat.) der Fakultät Biologie und Vorklinische Medizin der Universität Regensburg vorgelegt von Johannes Danner aus Eggenfelden im Jahr 2017 Das Promotionsgesuch wurde eingereicht am: 12.09.2017 Die Arbeit wurde angeleitet von: Prof. Dr. Gunter Meister Johannes Danner Summary ‘From microRNA biogenesis to post-translational modifications of TNRC6 complexes’ summarizes the two main projects, beginning with the influence of specific RNA binding proteins on miRNA biogenesis processes. The fate of the mature miRNA is determined by the incorporation into Argonaute proteins followed by a complex formation with TNRC6 proteins as core molecules of gene silencing complexes. miRNAs are transcribed as stem-loop structured primary transcripts (pri-miRNA) by Pol II. The further nuclear processing is carried out by the microprocessor complex containing the RNase III enzyme Drosha, which cleaves the pri-miRNA to precursor-miRNA (pre-miRNA). After Exportin-5 mediated transport of the pre-miRNA to the cytoplasm, the RNase III enzyme Dicer cleaves off the terminal loop resulting in a 21-24 nt long double-stranded RNA. One of the strands is incorporated in the RNA-induced silencing complex (RISC), where it directly interacts with a member of the Argonaute protein family. The miRNA guides the mature RISC complex to partially complementary target sites on mRNAs leading to gene silencing. During this process TNRC6 proteins interact with Argonaute and recruit additional factors to mediate translational repression and target mRNA destabilization through deadenylation and decapping leading to mRNA decay.

  • The PIWI Protein Aubergine Recruits Eif3 to Activate Translation in the Germ Plasm
    www.nature.com/cr www.cell-research.com ARTICLE OPEN The PIWI protein Aubergine recruits eIF3 to activate translation in the germ plasm Anne Ramat1, Maria-Rosa Garcia-Silva1, Camille Jahan1, Rima Naït-Saïdi1, Jérémy Dufourt 1,5, Céline Garret1, Aymeric Chartier1, Julie Cremaschi1, Vipul Patel1, Mathilde Decourcelle 2, Amandine Bastide3, François Juge 4 and Martine Simonelig 1 Piwi-interacting RNAs (piRNAs) and PIWI proteins are essential in germ cells to repress transposons and regulate mRNAs. In Drosophila, piRNAs bound to the PIWI protein Aubergine (Aub) are transferred maternally to the embryo and regulate maternal mRNA stability through two opposite roles. They target mRNAs by incomplete base pairing, leading to their destabilization in the soma and stabilization in the germ plasm. Here, we report a function of Aub in translation. Aub is required for translational activation of nanos mRNA, a key determinant of the germ plasm. Aub physically interacts with the poly(A)-binding protein (PABP) and the translation initiation factor eIF3. Polysome gradient profiling reveals the role of Aub at the initiation step of translation. In the germ plasm, PABP and eIF3d assemble in foci that surround Aub-containing germ granules, and Aub acts with eIF3d to promote nanos translation. These results identify translational activation as a new mode of mRNA regulation by Aub, highlighting the versatility of PIWI proteins in mRNA regulation. Cell Research (2020) 30:421–435; https://doi.org/10.1038/s41422-020-0294-9 1234567890();,: INTRODUCTION directly interacts with the Oskar (Osk) protein that is specifically Translational control is a widespread mechanism to regulate synthesized at the posterior pole of oocytes and embryos and gene expression in many biological contexts.

Unlike most of AID/APOBEC, however, APOBEC2’s function remains elusive. Previous research has implicated APOBEC2 in diverse organisms and cellular processes such as muscle biology (in Mus musculus), regeneration (in Danio rerio), and development (in Xenopus laevis). APOBEC2 has also been implicated in cancer. However the enzymatic activity, substrate or physiological target(s) of APOBEC2 are unknown. For this thesis, I have combined Next Generation Sequencing (NGS) techniques with state-of-the-art molecular biology to determine the physiological targets of APOBEC2. Using a cell culture muscle differentiation system, and RNA sequencing (RNA-Seq) by polyA capture, I demonstrated that unlike the AID/APOBEC family member APOBEC1, APOBEC2 is not an RNA editor. Using the same system combined with enhanced Reduced Representation Bisulfite Sequencing (eRRBS) analyses I showed that, unlike the AID/APOBEC family member AID, APOBEC2 does not act as a 5-methyl-C deaminase.

Background The evolutionarily conserved CCR4-NOT (CNOT) complex regulates mRNA metabolism in eukaryotic cells (1). This regulation occurs at different levels of mRNA synthesis and degradation, including transcription initiation, elongation, deadenylation, and degradation (1). Multiple components, including CNOT1, CNOT2, CNOT3, CNOT4, CNOT6, CNOT6L, CNOT7, CNOT8, CNOT9, and CNOT10 have been identified in this complex (2).

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.
