Mouse Plekha1 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Plekha1 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Plekha1 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Plekha1 gene (NCBI Reference Sequence: NM_133942 ; Ensembl: ENSMUSG00000040268 ) is located on Mouse chromosome 7. 10 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 10 (Transcript: ENSMUST00000048180). Exon 7 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Plekha1 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-211P16 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: Mcie homozygous for a gene trapped allele exhibit postnatal lethality and increased body weight. Exon 7 starts from about 50.47% of the coding region. The knockout of Exon 7 will result in frameshift of the gene. The size of intron 6 for 5'-loxP site insertion: 2624 bp, and the size of intron 7 for 3'-loxP site insertion: 456 bp. The size of effective cKO region: ~543 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(7021bp) | A(28.17% 1978) | C(19.07% 1339) | T(29.6% 2078) | G(23.16% 1626) 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.

  • Nuclear PTEN Safeguards Pre-Mrna Splicing to Link Golgi Apparatus for Its Tumor Suppressive Role
    ARTICLE DOI: 10.1038/s41467-018-04760-1 OPEN Nuclear PTEN safeguards pre-mRNA splicing to link Golgi apparatus for its tumor suppressive role Shao-Ming Shen1, Yan Ji2, Cheng Zhang1, Shuang-Shu Dong2, Shuo Yang1, Zhong Xiong1, Meng-Kai Ge1, Yun Yu1, Li Xia1, Meng Guo1, Jin-Ke Cheng3, Jun-Ling Liu1,3, Jian-Xiu Yu1,3 & Guo-Qiang Chen1 Dysregulation of pre-mRNA alternative splicing (AS) is closely associated with cancers. However, the relationships between the AS and classic oncogenes/tumor suppressors are 1234567890():,; largely unknown. Here we show that the deletion of tumor suppressor PTEN alters pre-mRNA splicing in a phosphatase-independent manner, and identify 262 PTEN-regulated AS events in 293T cells by RNA sequencing, which are associated with significant worse outcome of cancer patients. Based on these findings, we report that nuclear PTEN interacts with the splicing machinery, spliceosome, to regulate its assembly and pre-mRNA splicing. We also identify a new exon 2b in GOLGA2 transcript and the exon exclusion contributes to PTEN knockdown-induced tumorigenesis by promoting dramatic Golgi extension and secretion, and PTEN depletion significantly sensitizes cancer cells to secretion inhibitors brefeldin A and golgicide A. Our results suggest that Golgi secretion inhibitors alone or in combination with PI3K/Akt kinase inhibitors may be therapeutically useful for PTEN-deficient cancers. 1 Department of Pathophysiology, Key Laboratory of Cell Differentiation and Apoptosis of Chinese Ministry of Education, Shanghai Jiao Tong University School of Medicine (SJTU-SM), Shanghai 200025, China. 2 Institute of Health Sciences, Shanghai Institutes for Biological Sciences of Chinese Academy of Sciences and SJTU-SM, Shanghai 200025, China.

  • A Multiethnic Genome-Wide Analysis of 44,039 Individuals Identifies 41 New Loci Associated with Central Corneal Thickness
    ARTICLE https://doi.org/10.1038/s42003-020-1037-7 OPEN A multiethnic genome-wide analysis of 44,039 individuals identifies 41 new loci associated with central corneal thickness ✉ Hélène Choquet 1 , Ronald B. Melles2, Jie Yin1, Thomas J. Hoffmann 3,4, Khanh K. Thai1, Mark N. Kvale3, 1234567890():,; Yambazi Banda3, Alison J. Hardcastle 5,6, Stephen J. Tuft7, M. Maria Glymour4, Catherine Schaefer 1, ✉ Neil Risch1,3,4, K. Saidas Nair8, Pirro G. Hysi 9,10,11 & Eric Jorgenson 1 Central corneal thickness (CCT) is one of the most heritable human traits, with broad-sense heritability estimates ranging between 0.68 to 0.95. Despite the high heritability and numerous previous association studies, only 8.5% of CCT variance is currently explained. Here, we report the results of a multiethnic meta-analysis of available genome-wide asso- ciation studies in which we find association between CCT and 98 genomic loci, of which 41 are novel. Among these loci, 20 were significantly associated with keratoconus, and one (RAPSN rs3740685) was significantly associated with glaucoma after Bonferroni correction. Two-sample Mendelian randomization analysis suggests that thinner CCT does not causally increase the risk of primary open-angle glaucoma. This large CCT study explains up to 14.2% of CCT variance and increases substantially our understanding of the etiology of CCT var- iation. This may open new avenues of investigation into human ocular traits and their rela- tionship to the risk of vision disorders. 1 Kaiser Permanente Northern California (KPNC), Division of Research, Oakland, CA 94612, USA. 2 KPNC, Department of Ophthalmology, Redwood City, CA 94063, USA.

Elevated levels of reactive oxygen species (ROS) have been proposed as a risk factor for the development of papillary thyroid carcinoma (PTC) in patients with Hashimoto thyroiditis (HT). However, it has yet to be proven that the total levels of ROS are sufficiently increased to contribute to carcinogenesis. We hypothesized that if the ROS levels were increased in HT, ROS-related genes would also be differently expressed in PTC with HT. To find differentially expressed genes (DEGs) we analyzed data from the Cancer Genomic Atlas, gene expression data from RNA sequencing: 33 from normal thyroid tissue, 232 from PTC without HT, and 60 from PTC with HT.

  • Specific Correlation Between the Major Chromosome 10Q26 Haplotype Conferring Risk for Age-Related Macular Degeneration and the Expression of HTRA1
    Molecular Vision 2017; 23:318-333 <http://www.molvis.org/molvis/v23/318> © 2017 Molecular Vision Received 5 December 2016 | Accepted 12 June 2017 | Published 14 June 2017 Specific correlation between the major chromosome 10q26 haplotype conferring risk for age-related macular degeneration and the expression of HTRA1 Sha-Mei Liao,1 Wei Zheng,1 Jiang Zhu,2 Casey A. Lewis,1 Omar Delgado,1 Maura A. Crowley,1 Natasha M. Buchanan,1 Bruce D. Jaffee,1 Thaddeus P. Dryja1 1Department of Ophthalmology; NIBR Informatics, Novartis Institutes for Biomedical Research, Cambridge, MA; 2Scientific Data Analysis, NIBR Informatics, Novartis Institutes for Biomedical Research, Cambridge, MA Purpose: A region within chromosome 10q26 has a set of single nucleotide polymorphisms (SNPs) that define a haplo- type that confers high risk for age-related macular degeneration (AMD). We used a bioinformatics approach to search for genes in this region that may be responsible for risk for AMD by assessing levels of gene expression in individuals carrying different haplotypes and by searching for open chromatin regions in the retinal pigment epithelium (RPE) that might include one or more of the SNPs. Methods: We surveyed the PubMed and the 1000 Genomes databases to find all common (minor allele frequency > 0.01) SNPs in 10q26 strongly associated with AMD. We used the HaploReg and LDlink databases to find sets of SNPs with alleles in linkage disequilibrium and used the Genotype-Tissue Expression (GTEx) database to search for correlations between genotypes at individual SNPs and the relative level of expression of the genes. We also accessed Encyclopedia of DNA Elements (ENCODE) to find segments of open chromatin in the region with the AMD-associated SNPs.
