Mouse Fam49a Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Fam49a Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Fam49a conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Fam49a gene (NCBI Reference Sequence: NM_029758 ; Ensembl: ENSMUSG00000020589 ) is located on Mouse chromosome 12. 13 exons are identified, with the ATG start codon in exon 4 and the TAG stop codon in exon 13 (Transcript: ENSMUST00000069066). Exon 5 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Fam49a gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-184A24 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 5 starts from about 7.33% of the coding region. The knockout of Exon 5 will result in frameshift of the gene. The size of intron 4 for 5'-loxP site insertion: 17286 bp, and the size of intron 5 for 3'-loxP site insertion: 1046 bp. The size of effective cKO region: ~622 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(7122bp) | A(27.7% 1973) | C(21.08% 1501) | T(30.16% 2148) | G(21.06% 1500) 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.

  • Dnp63a Represses Anti-Proliferative Genes Via H2A.Z Deposition
    Downloaded from genesdev.cshlp.org on September 28, 2021 - Published by Cold Spring Harbor Laboratory Press DNp63a represses anti-proliferative genes via H2A.Z deposition Corrie L. Gallant-Behm,1,2 Matthew R. Ramsey,3 Claire L. Bensard,1,2 Ignacio Nojek,1,2 Jack Tran,1,2 Minghua Liu,1,2 Leif W. Ellisen,3 and Joaquı´n M. Espinosa1,2,4 1Howard Hughes Medical Institute, 2Department of Molecular, Cellular, and Developmental Biology, University of Colorado at Boulder, Boulder, Colorado 80309, USA; 3Massachusetts General Hospital Cancer Center, Harvard Medical School, Boston, Massachusetts 02114, USA DNp63a is a member of the p53 family of transcription factors that functions as an oncogene in squamous cell carcinomas (SCCs). Because DNp63a and p53 bind virtually identical DNA sequence motifs, it has been proposed that DNp63a functions as a dominant-negative inhibitor of p53 to promote proliferation and block apoptosis. However, most SCCs concurrently overexpress DNp63a and inactivate p53, suggesting the autonomous action of these oncogenic events. Here we report the discovery of a novel mechanism of transcriptional repression by DNp63a that reconciles these observations. We found that although both proteins bind the same genomic sites, they regulate largely nonoverlapping gene sets. Upon activation, p53 binds all enhancers regardless of DNp63a status but fails to transactivate genes repressed by DNp63a. We found that DNp63a associates with the SRCAP chromatin regulatory complex involved in H2A/H2A.Z exchange and mediates H2A.Z deposition at its target loci. Interestingly, knockdown of SRCAP subunits or H2A.Z leads to specific induction of DNp63a-repressed genes. We identified SAMD9L as a key anti-proliferative gene repressed by DNp63a and H2A.Z whose depletion suffices to reverse the arrest phenotype caused by DNp63a knockdown.

Different mechanisms have been proposed to explain their genesis. Recently, our group showed that the MYC-containing dmin in leukemia cases arise by excision and amplification (episome model). In the present paper we investigated 10 cell lines from solid tumors showing MYCN amplification as dmin or hsr. Particularly revealing results were provided by the two subclones of the neuroblastoma cell line STA-NB-10, one showing dmin-only and the second hsr-only amplification. Both subclones showed a deletion, at 2p24.3, whose extension matched the amplicon extension.

To characterize these changes, RNA was extracted and sequenced from muscle biopsies col- 1234567890():,; lected from 53 healthy individuals (22–83 years old) of the GESTALT study of the National Institute on Aging–NIH. Expression levels of 57,205 protein-coding and non-coding RNAs were studied as a function of aging by linear and negative binomial regression models. From both models, 1134 RNAs changed significantly with age. The most differentially abundant mRNAs encoded proteins implicated in several age-related processes, including cellular senescence, insulin signaling, and myogenesis. Specific mRNA isoforms that changed sig- nificantly with age in skeletal muscle were enriched for proteins involved in oxidative phosphorylation and adipogenesis. Our study establishes a detailed framework of the global transcriptome and mRNA isoforms that govern muscle damage and homeostasis with age. ✉ 1 National Institute on Aging–Intramural Research Program, National

  • Early Vertebrate Whole Genome Duplications Were Predated by a Period of Intense Genome Rearrangement

Abstract Researchers, supported by data from polyploid plants, have suggested that whole genome duplication (WGD) may induce genomic instability and rearrangement, an idea which could have important implications for vertebrate evolution. Benefiting from the newly released amphioxus genome sequence (Branchiostoma floridae), an invertebrate which researchers have hoped is representative of the ancestral chordate genome, we have used gene proximity conservation to estimate rates of genome rearrangement throughout vertebrates and some of their invertebrate ancestors. We find that, while amphioxus remains the best single source of invertebrate information about the early chordate genome, its genome structure is not particularly well conserved and it cannot be considered a fossilization of the vertebrate pre- duplication genome. In agreement with previous reports, we identify two WGD events in early vertebrates and another in teleost fish.

  • The Glomerular Transcriptome and a Predicted Protein–Protein Interaction Network

We generated a combined catalogue of glomerulus-enriched genes that emerged from these different sources and then used this to construct a predicted protein–protein interaction network in the glomerulus (GlomNet). The combined glomerulus-enriched gene catalogue provides the most comprehensive picture of the molecular composition of the glomerulus currently available, and GlomNet contributes an integrative systems biology approach to the understanding of glomerular signaling networks that operate during development, function, and disease.

Structure-Function Relationships Of Rna And Protein In Synaptic Plasticity Abstract Structure is widely acknowledged to be important for the function of ribonucleic acids (RNAs) and proteins. However, due to the relative accessibility of sequence information compared to structure information, most large genomics studies currently use only sequence-based annotation tools to analyze the function of expressed molecules. In this thesis, I introduce two novel computational methods for genome-scale structure-function analysis and demonstrate their application to identifying RNA and protein structures involved in synaptic plasticity and potentiation—important neuronal processes that are thought to form the basis of learning and memory. First, I describe a new method for de novo identification of RNA secondary structure motifs enriched in co-regulated transcripts. I show that this method can accurately identify secondary structure motifs that recur across three or more transcripts in the input set with an average recall of 0.80 and precision of 0.98. Second, I describe a tool for predicting protein structural fold from amino acid sequence, which achieves greater than 96% accuracy on benchmarks and can be used to predict protein function and identify new structural folds.
