Mouse Mdh2 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Mdh2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Mdh2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Mdh2 gene (NCBI Reference Sequence: NM_008617 ; Ensembl: ENSMUSG00000019179 ) is located on Mouse chromosome 5. 9 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 9 (Transcript: ENSMUST00000019323). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Mdh2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-153M11 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 2 starts from about 6.61% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 4503 bp, and the size of intron 2 for 3'-loxP site insertion: 710 bp. The size of effective cKO region: ~864 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(7169bp) | A(25.28% 1812) | C(22.3% 1599) | T(25.9% 1857) | G(26.52% 1901) 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.

Deplancke, rapporteur Suisse 2016 Acknowledgements First of all, I would like to thank my thesis supervisor, Yann Barrandon, for giving me the opportunity to work in his laboratory and for supporting me to develop my ideas. I am very grateful that he provided me the tools and the environment to grow as a scientist and to explore very interesting questions at the interface between clinical and basic stem cell research. I warmly thank the members of my thesis jury, Prof. Giulio Cossu, Prof. Bart Deplancke, Prof. Shinichi Nishikawa and Prof. Daniel Constam for taking the time to evaluate and discuss my work. I would like to acknowledge Ariane Rochat for her help and contribution to this thesis. The project on the 3T3-J2 cells would not have been possible without her teaching and critical work to maintain the culture system in stellar conditions. Thanks to her, I was able to perform experiments on precious human skin biopsies. She also contributed in preparing the cell samples for the telomere experiment. I also would like to thank the team of the Biomolecular Screening Facility (BSF).

Kandasamy ([email protected]) Abstract Dual specificity phosphatases (DUSPs) have a well-known role as regulators of the immune response through the modulation of mitogen activated protein kinases (MAPKs). Yet the precise interplay between the various members of the DUSP family with protein kinases is not well understood. Recent multi-omics studies characterizing the transcriptomes and proteomes of immune cells have provided snapshots of molecular mechanisms underlying innate immune response in unprecedented detail. In this study, we focused on deciphering the interplay between members of the DUSP family with protein kinases in immune cells using publicly available omics datasets. Our analysis resulted in the identification of potential DUSP- mediated hub proteins including MAPK7, MAPK8, AURKA, and IGF1R. Furthermore, we analyzed the association of DUSP expression with TLR4 signaling and identified VEGF, FGFR and SCF-KIT pathway modules to be regulated by the activation of TLR4 signaling.

  • A Biochemical Landscape of A-To-I RNA Editing in the Human Brain Transcriptome
    Downloaded from genome.cshlp.org on October 3, 2021 - Published by Cold Spring Harbor Laboratory Press Resource A biochemical landscape of A-to-I RNA editing in the human brain transcriptome Masayuki Sakurai,1,4 Hiroki Ueda,1,4 Takanori Yano,1 Shunpei Okada,1 Hideki Terajima,1 Toutai Mitsuyama,2 Atsushi Toyoda,3 Asao Fujiyama,3 Hitomi Kawabata,1 and Tsutomu Suzuki1,5 1Department of Chemistry and Biotechnology, Graduate School of Engineering, University of Tokyo, Tokyo 113-8656, Japan; 2Computational Biology Research Center (CBRC), National Institute of Advanced Industrial Science and Technology (AIST), Tokyo 135-0064, Japan; 3Comparative Genomics Laboratory, Center for Genetic Resource Information, National Institute of Genetics, Shizuoka 411-8540, Japan Inosine is an abundant RNA modification in the human transcriptome and is essential for many biological processes in modulating gene expression at the post-transcriptional level. Adenosine deaminases acting on RNA (ADARs) catalyze the hydrolytic deamination of adenosines to inosines (A-to-I editing) in double-stranded regions. We previously established a biochemical method called ‘‘inosine chemical erasing’’ (ICE) to directly identify inosines on RNA strands with high reliability. Here, we have applied the ICE method combined with deep sequencing (ICE-seq) to conduct an unbiased genome-wide screening of A-to-I editing sites in the transcriptome of human adult brain. Taken together with the sites identified by the conventional ICE method, we mapped 19,791 novel sites and newly found 1258 edited mRNAs, including 66 novel sites in coding regions, 41 of which cause altered amino acid assignment. ICE-seq detected novel editing sites in various repeat elements as well as in short hairpins.

Hensel, PhD* Neurol Genet 2019;5:e378. doi:10.1212/NXG.0000000000000378 Abstract Objective To evaluate a new tool to aid interpretation of copy number variants (CNVs) in individuals with neurodevelopmental disabilities. Methods Critical exon indexing (CEI) was used to identify genes with critical exons (CEGs) from clinically reported CNVs, which may contribute to neurodevelopmental disorders (NDDs). The 742 pathogenic CNVs and 1,363 variants of unknown significance (VUS) identified by chromosomal microarray analysis in 5,487 individuals with NDDs were subjected to CEI to identify CEGs. CEGs identified in a subsequent random series of VUS were evaluated for relevance to CNV interpretation. Results CEI identified a total of 2,492 unique CEGs in pathogenic CNVs and 953 in VUS compared with 259 CEGs in 6,965 CNVs from 873 controls. These differences are highly significant (p < 0.00001) whether compared as frequency, average, or normalized by CNV size. Twenty-one percent of VUS CEGs were not represented in Online Mendelian Inheritance in Man, high- lighting limitations of existing resources for identifying potentially impactful genes within CNVs. CEGs were highly correlated with other indices and known pathways of relevance.

Rats self-trained on a standard two-lever operant paradigm to administer either water- water, EtOH (15% v/v)-water, or saccharin (SAC; 0.0125% g/v)-water. Animals were killed 24 hr after the last operant session, and the ACB and AMYG dissected; RNA was extracted and purified for microarray analysis.
