Mouse Pip4k2a Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Pip4k2a Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Pip4k2a conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Pip4k2a gene (NCBI Reference Sequence: NM_008845 ; Ensembl: ENSMUSG00000026737 ) is located on Mouse chromosome 2. 10 exons are identified, with the ATG start codon in exon 1 and the TAA stop codon in exon 10 (Transcript: ENSMUST00000006912). 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 Pip4k2a gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-346P16 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: Mice homozygous for a null allele are viable and appear phenotypically normal. Exon 2 starts from about 11.93% 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: 89699 bp, and the size of intron 2 for 3'-loxP site insertion: 1729 bp. The size of effective cKO region: ~598 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(7098bp) | A(25.98% 1844) | C(22.67% 1609) | T(27.92% 1982) | G(23.43% 1663) 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.

  • Identification of Four Novel Associations for B-Cell Acute
    ARTICLE https://doi.org/10.1038/s41467-019-13069-6 OPEN Identification of four novel associations for B-cell acute lymphoblastic leukaemia risk Jayaram Vijayakrishnan 1,19, Maoxiang Qian2,3,19, James B. Studd 1, Wenjian Yang2, Ben Kinnersley 1, Philip J. Law 1, Peter Broderick 1, Elizabeth A. Raetz4, James Allan5, Ching-Hon Pui 6,7, Ajay Vora8, William E.

Relling2,7, Martin Stanulla15, Mignon L. Loh18, Richard S. Houlston 1* & Jun J. Yang 2,6,7* 1234567890():,; There is increasing evidence for a strong inherited genetic basis of susceptibility to acute lymphoblastic leukaemia (ALL) in children. To identify new risk variants for B-cell ALL (B-ALL) we conducted a meta-analysis with four GWAS (genome-wide association studies), totalling 5321 cases and 16,666 controls of European descent. We herein describe novel risk loci for B-ALL at 9q21.31 (rs76925697, P = 2.11 × 10−8), for high-hyperdiploid ALL at 5q31.1 (rs886285, P = 1.56 × 10−8) and 6p21.31 (rs210143 in BAK1, P = 2.21 × 10−8), and ETV6- RUNX1 ALL at 17q21.32 (rs10853104 in IGF2BP1, P = 1.82 × 10−8). Particularly notable are the pleiotropic effects of the BAK1 variant on multiple haematological malignancies and specific effects of IGF2BP1 on ETV6-RUNX1 ALL evidenced by both germline and somatic genomic analyses. Integration of GWAS signals with transcriptomic/epigenomic profiling and 3D chromatin interaction data for these leukaemia risk loci suggests deregulation of B-cell development and the cell cycle as central mechanisms governing genetic susceptibility to ALL.

This article is published with open access Abstract Genetic variation may mediate the increased risk of cardiovascular disease (CVD) in chemotherapy-treated testicular cancer (TC) patients compared to the general population. Involved single nucleotide polymorphisms (SNPs) might differ from known CVD-associated SNPs in the general population. We performed an explorative genome-wide association study (GWAS) in TC patients. TC patients treated with platinum-based chemotherapy between 1977 and 2011, age ≤55 years at diagnosis, and ≥3 years relapse-free follow-up were genotyped. Association between SNPs and CVD occurrence during 1234567890();,: 1234567890();,: treatment or follow-up was analyzed. Data-driven Expression Prioritized Integration for Complex Trait (DEPICT) provided insight into enriched gene sets, i.e., biological themes. During a median follow-up of 11 years (range 3–37), CVD occurred in 53 (14%) of 375 genotyped patients. Based on 179 SNPs associated at p ≤ 0.001, 141 independent genomic loci associated with CVD occurrence. Subsequent, DEPICT found ten biological themes, with the RAC2/RAC3 network (linked to endothelial activation) as the most prominent theme. Biology of this network was illustrated in a TC cohort (n = 60) by increased circulating endothelial cells during chemotherapy.

  • Resolution of Structure of PIP5K1A Reveals Molecular Mechanism for Its Regulation by Dimerization and Dishevelled
    ARTICLE Received 8 Apr 2015 | Accepted 28 Jul 2015 | Published 14 Sep 2015 DOI: 10.1038/ncomms9205 OPEN Resolution of structure of PIP5K1A reveals molecular mechanism for its regulation by dimerization and dishevelled Jian Hu1,w,*, Qianying Yuan1,2,*, Xue Kang1,2, Yuanbo Qin3, Lin Li3,YaHa1 & Dianqing Wu1,2 Type I phosphatidylinositol phosphate kinase (PIP5K1) phosphorylates the head group of phosphatidylinositol 4-phosphate (PtdIns4P) to generate PtdIns4,5P2, which plays important roles in a wide range of cellular functions including Wnt signalling. However, the lack of its structural information has hindered the understanding of its regulation. Here we report the crystal structure of the catalytic domain of zebrafish PIP5K1A at 3.3 Å resolution. This molecule forms a side-to-side dimer. Mutagenesis study of PIP5K1A reveals two adjacent interfaces for the dimerization and interaction with the DIX domain of the Wnt signalling molecule dishevelled. Although these interfaces are located distally to the catalytic/substrate-binding site, binding to these interfaces either through dimerization or the interaction with DIX stimulates PIP5K1 catalytic activity. DIX binding additionally enhances PIP5K1 substrate binding. Thus, this study elucidates regulatory mechanisms for this lipid kinase and provides a paradigm for the understanding of PIP5K1 regulation by their interacting molecules. 1 Department of Pharmacology, Yale School of Medicine, New Haven, Connecticut 06520, USA. 2 Vascular Biology and Therapeutic Program, Yale School of Medicine, New Haven, Connecticut 06520 USA. 3 State Key Laboratory of Molecular Biology, Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai 200031, China. w Present address: Department of Biochemistry and Molecular Biology and Department of Chemistry, Michigan State University, East Lansing, Michigan 48824, USA.

  • Functional Analysis of the Biochemical Activity of Mammalian Phosphatidylinositol 5 Phosphate 4-Kinase Enzymes
    Bioscience Reports (2019) 39 BSR20182210 https://doi.org/10.1042/BSR20182210 Research Article Functional analysis of the biochemical activity of mammalian phosphatidylinositol 5 phosphate 4-kinase enzymes Swarna Mathre1,2, K. Balasankara Reddy1, Visvanathan Ramya1, Harini Krishnan1, Avishek Ghosh1 and Padinjat Raghu1 1National Centre for Biological Sciences, TIFR-GKVK Campus, Bellary Road, Bangalore 560065, India; 2School of Life Sciences, Manipal Academy of Higher Education, Manipal 576104, Karnataka, India Correspondence: Padinjat Raghu ([email protected]) Phosphatidylinositol 5 phosphate 4-kinase (PIP4K) are enzymes that catalyse the phos- phorylation of phosphatidylinositol 5-phosphate (PI5P) to generate PI(4,5)P2. Mammalian genomes contain three genes, PIP4K2α, 2B and 2C and murine knockouts for these sug- gested important physiological roles in vivo. The proteins encoded by PIP4K2A, 2B and 2C show widely varying specific activities in vitro; PIP4K2A is highly active and PIP4K2C 2000-times less active, and the relationship between this biochemical activity and in vivo function is unknown. By contrast, the Drosophila genome encodes a single PIP4K (dPIP4K) that shows high specific activity in vitro and loss of this enzyme results in reduced salivary gland cell size in vivo. We find that the kinase activity of dPIP4K is essential for normal sali- vary gland cell size in vivo. Despite their highly divergent specific activity, we find that all three mammalian PIP4K isoforms are able to enhance salivary gland cell size in the Drosophila PIP4K null mutant implying a lack of correlation between in vitro activity measurements and in vivo function. Further, the kinase activity of PIP4K2C, reported to be almost inactive in vitro, is required for in vivo function.
