Mouse Rcc2 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Rcc2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Rcc2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Rcc2 gene (NCBI Reference Sequence: NM_173867 ; Ensembl: ENSMUSG00000040945 ) is located on Mouse chromosome 4. 13 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 13 (Transcript: ENSMUST00000038893). 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 Rcc2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-275J10 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 3 starts from about 17.95% 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: 5515 bp, and the size of intron 3 for 3'-loxP site insertion: 2288 bp. The size of effective cKO region: ~594 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(7094bp) | A(19.82% 1406) | C(24.44% 1734) | T(25.95% 1841) | G(29.79% 2113) 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.

  • Analysis of Microarray Data on Gene Expression and Methylation to Identify Long Non-Coding Rnas in Non-Small Cell Lung Cancer
    www.nature.com/scientificreports OPEN Analysis of Microarray Data on Gene Expression and Methylation to Identify Long Non-coding RNAs Received: 16 August 2016 Accepted: 26 October 2016 in Non-small Cell Lung Cancer Published: 16 November 2016 Nannan Feng1,*, Travers Ching2,*, Yu Wang3, Ben Liu3, Hongyan Lin1, Oumin Shi1, Xiaohong Zhang1, Min Zheng1, Xin Zheng1, Ming Gao3, Zhi-jie Zheng1, Herbert Yu2, Lana Garmire2,† & Biyun Qian1,† To identify what long non-coding RNAs (lncRNAs) are involved in non-small cell lung cancer (NSCLC), we analyzed microarray data on gene expression and methylation. Gene expression chip and HumanMethylation450BeadChip were used to interrogate genome-wide expression and methylation in tumor samples. Differential expression and methylation were analyzed through comparing tumors with adjacent non-tumor tissues. LncRNAs expressed differentially and correlated with coding genes and DNA methylation were validated in additional tumor samples using RT-qPCR and pyrosequencing. In vitro experiments were performed to evaluate lncRNA’s effects on tumor cells. We identified 8,500 lncRNAs expressed differentially between tumor and non-tumor tissues, of which 1,504 were correlated with mRNA expression. Two of the lncRNAs, LOC146880 and ENST00000439577, were positively correlated with expression of two cancer-related genes, KPNA2 and RCC2, respectively. High expression of LOC146880 and ENST00000439577 were also associated with poor survival. Analysis of lncRNA expression in relation to DNA methylation showed that LOC146880 expression was down-regulated by DNA methylation in its promoter. Lowering the expression of LOC146880 or ENST00000439577 in tumor cells could inhibit cell proliferation, invasion and migration. Analysis of microarray data on gene expression and methylation allows us to identify two lncRNAs, LOC146880 and ENST00000439577, which may promote the progression of NSCLC.

  • How Does SUMO Participate in Spindle Organization?
    cells Review How Does SUMO Participate in Spindle Organization? Ariane Abrieu * and Dimitris Liakopoulos * CRBM, CNRS UMR5237, Université de Montpellier, 1919 route de Mende, 34090 Montpellier, France * Correspondence: [email protected] (A.A.); [email protected] (D.L.) Received: 5 July 2019; Accepted: 30 July 2019; Published: 31 July 2019 Abstract: The ubiquitin-like protein SUMO is a regulator involved in most cellular mechanisms. Recent studies have discovered new modes of function for this protein. Of particular interest is the ability of SUMO to organize proteins in larger assemblies, as well as the role of SUMO-dependent ubiquitylation in their disassembly. These mechanisms have been largely described in the context of DNA repair, transcriptional regulation, or signaling, while much less is known on how SUMO facilitates organization of microtubule-dependent processes during mitosis. Remarkably however, SUMO has been known for a long time to modify kinetochore proteins, while more recently, extensive proteomic screens have identified a large number of microtubule- and spindle-associated proteins that are SUMOylated. The aim of this review is to focus on the possible role of SUMOylation in organization of the spindle and kinetochore complexes. We summarize mitotic and microtubule/spindle-associated proteins that have been identified as SUMO conjugates and present examples regarding their regulation by SUMO. Moreover, we discuss the possible contribution of SUMOylation in organization of larger protein assemblies on the spindle, as well as the role of SUMO-targeted ubiquitylation in control of kinetochore assembly and function. Finally, we propose future directions regarding the study of SUMOylation in regulation of spindle organization and examine the potential of SUMO and SUMO-mediated degradation as target for antimitotic-based therapies.

  • Prediction Model for Aneuploidy in Early Human Embryo Development Revealed by Single-Cell Analysis
    ARTICLE Received 26 Sep 2014 | Accepted 22 May 2015 | Published 7 Jul 2015 DOI: 10.1038/ncomms8601 OPEN Prediction model for aneuploidy in early human embryo development revealed by single-cell analysis Maria Vera-Rodriguez1,2,3, Shawn L. Chavez1,2,w, Carmen Rubio3,4, Renee A. Reijo Pera1,2,w & Carlos Simon2,3,4 Aneuploidies are prevalent in the human embryo and impair proper development, leading to cell cycle arrest. Recent advances in imaging and molecular and genetic analyses are postulated as promising strategies to unveil the mechanisms involved in aneuploidy generation. Here we combine time-lapse, complete chromosomal assessment and single-cell RT–qPCR to simultaneously obtain information from all cells that compose a human embryo until the approximately eight-cell stage (n ¼ 85). Our data indicate that the chromosomal status of aneuploid embryos (n ¼ 26), including those that are mosaic (n ¼ 3), correlates with significant differences in the duration of the first mitotic phase when compared with euploid embryos (n ¼ 28). Moreover, gene expression profiling suggests that a subset of genes is differentially expressed in aneuploid embryos during the first 30 h of development. Thus, we propose that the chromosomal fate of an embryo is likely determined as early as the pronuclear stage and may be predicted by a 12-gene transcriptomic signature. 1 Institute for Stem Cell Biology and Regenerative Medicine, Center for Reproductive and Stem Cell Biology, Stanford, California 94305, USA. 2 Department of Obstetrics and Gynecology, Institute for Stem Cell Biology and Regenerative Medicine, Center for Reproductive and Stem Cell Biology, Stanford, California 94305, USA.

  • Exome Sequencing and Array-Based Comparative Genomic Hybridisation Analysis of Preferential 6-Methylmercaptopurine Producers
    The Pharmacogenomics Journal (2015) 15, 414–421 © 2015 Macmillan Publishers Limited All rights reserved 1470-269X/15 www.nature.com/tpj ORIGINAL ARTICLE Exome sequencing and array-based comparative genomic hybridisation analysis of preferential 6-methylmercaptopurine producers EW Chua1,2, S Cree1, ML Barclay3,4, K Doudney5, K Lehnert6, A Aitchison1 and MA Kennedy1 Preferential conversion of azathioprine or 6-mercaptopurine into methylated metabolites is a major cause of thiopurine resistance. To seek potentially Mendelian causes of thiopurine hypermethylation, we recruited 12 individuals who exhibited extreme therapeutic resistance while taking azathioprine or 6-mercaptopurine and performed whole-exome sequencing (WES) and copy- number variant analysis by array-based comparative genomic hybridisation (aCGH). Exome-wide variant filtering highlighted four genes potentially associated with thiopurine metabolism (ENOSF1 and NFS1), transport (SLC17A4) or therapeutic action (RCC2). However, variants of each gene were found only in two or three patients, and it is unclear whether these genes could influence thiopurine hypermethylation. Analysis by aCGH did not identify any unusual or pathogenic copy-number variants. This suggests that if causative mutations for the hypermethylation phenotype exist they may be heterogeneous, occurring in several different genes, or they may lie within regulatory regions not captured by WES. Alternatively, hypermethylation may arise from the involvement of multiple genes with small effects. To test this hypothesis would require recruitment of large patient samples and application of genome-wide association studies.

  • RCC2 Is a Novel P53 Target in Suppressing Metastasis
    OPEN Oncogene (2018) 37,8–17 www.nature.com/onc ORIGINAL ARTICLE RCC2 is a novel p53 target in suppressing metastasis C Song1, L Liang1, Y Jin, Y Li, Y Liu, L Guo, C Wu, C-H Yun and Y Yin RCC2 (also known as TD60) is a highly conserved protein involved in prognosis in colorectal cancer. However, its relationship with tumor development is less understood. Here we demonstrate a signaling pathway defining regulation of RCC2 and its functions in tumor progression. We report that p53 is a transcriptional regulator of RCC2 that acts through its binding to a palindromic motif in the RCC2 promoter. RCC2 physically interacts and deactivates a small GTPase Rac1 that is known to be involved in metastasis. We solved a high-resolution crystal structure of RCC2 and revealed one RCC1-like domain with a unique β-hairpin that is requisite for RCC2 interaction with Rac1. p53 or RCC2 deficiency leads to activation of Rac1 and deterioration of extracellular matrix sensing (haptotaxis) of surface-bound gradients. Ectopic expression of RCC2 restores directional migration in p53-null cells. Our results demonstrate that p53 and RCC2 signaling is important for regulation of cell migration and suppression of metastasis. We propose that the p53/RCC2/Rac1 axis is a potential target for cancer therapy.
