Mouse Steap4 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Steap4 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Steap4 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Steap4 gene (NCBI Reference Sequence: NM_054098 ; Ensembl: ENSMUSG00000012428 ) is located on Mouse chromosome 5. 5 exons are identified, with the ATG start codon in exon 2 and the TAA stop codon in exon 5 (Transcript: ENSMUST00000115421). Exon 2~3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Steap4 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-212F6 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 knock-out allele exhibit adipose accumulation, oxidative stress, increased liver weight, lower metabolic rate, hypoactivity, insulin resistance, glucose intolerance, mild hyperglycemia and dyslipidemia. Exon 2 starts from about 100% of the coding region. The knockout of Exon 2~3 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 14897 bp, and the size of intron 3 for 3'-loxP site insertion: 1385 bp. The size of effective cKO region: ~2082 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(8584bp) | A(29.4% 2524) | C(20.51% 1761) | T(29.49% 2531) | G(20.6% 1768) 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.

    1 SUPPLEMENTARY MATERIALS 2 Supplementary Methods 3 Study design 4 The workflow to identify and validate the TME risk score and TME subtypes in gastric cancer is 5 depicted in Fig. S1. We first estimated the absolute abundance levels of the major stromal and 6 immune cell types in the TME using bulk gene expression data, and assessed the prognostic 7 effect of these cells in a discovery cohort. Next, we constructed a TME risk score and validated it 8 in two independent gene expression validation cohorts and three immunohistochemistry 9 validation cohorts. Finally, we stratified patients into four TME subtypes and examined their 10 genomic and molecular features and relation to established molecular subtypes. 11 Gene expression data 12 To explore the prognostic landscape of the TME, we used four gene expression profile (GEP) 13 datasets of resected gastric cancer patients with publicly available clinical information, namely, 14 ACRG (GSE62254) (1), GSE15459 (2), GSE84437 (3), and TCGA stomach adenocarcinoma 15 (STAD). Specifically, the raw microarray data in the ACRG cohort and GSE15459 were retrieved 16 from the Gene Expression Omnibus (GEO), and normalized by the RMA algorithm (package affy) 17 using custom chip definition files (Brainarray version 23 (4)) that convert Affymetrix probesets to 18 Entrez gene IDs. For GSE84437 dataset, which was measured by the Illumina platform, we 19 downloaded the normalized gene expression profile from the GEO (package GEOquery (5)). The 20 Illumina probes were also mapped to Entrez genes. For multiple probes mapping to the same 21 Entrez gene, we selected the one with the maximum mean expression level as the surrogate for 22 the Entrez gene using the function of collapseRows (6) (package WGCNA).

Although their biological importance is undisputed, the level of mesenchymal cell heterogeneity within and between organs, while appreciated, has not been analyzed in detail. Here, we compare single-cell transcriptional profiles of fibroblasts and vascular mural cells across four murine muscular organs: heart, skeletal muscle, intestine and bladder. We reveal gene expression signatures that demarcate fibroblasts from mural cells and provide molecular signatures for cell subtype identification. We observe striking inter- and intra-organ heterogeneity amongst the fibroblasts, primarily reflecting differences in the expression of extracellular matrix components. Fibroblast subtypes localize to discrete anatomical positions offering novel predictions about physiological function(s) and regulatory signaling circuits. Our data shed new light on the diversity of poorly defined classes of cells and provide a foundation for improved understanding of their roles in physiological and pathological processes. 1 Karolinska Institutet/AstraZeneca Integrated Cardio Metabolic Centre, Blickagången 6, SE-14157 Huddinge, Sweden.

  • Primepcr™Assay Validation Report
    PrimePCR™Assay Validation Report Gene Information Gene Name STEAP family member 4 Gene Symbol STEAP4 Organism Human Gene Summary The protein encoded by this gene belongs to the STEAP (six transmembrane epithelial antigen of prostate) family and resides in the golgi apparatus. It functions as a metalloreductase that has the ability to reduce both Fe(3+) to Fe(2+) and Cu(2+) to Cu(1+) using NAD(+) as acceptor. Studies in mice and human suggest that this gene maybe involved in adipocyte development and metabolism and may contribute to the normal biology of the prostate cell as well as prostate cancer progression. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Transcriptome analysis of Traf6 function in the 4 innate immune response of zebrafish embryos Oliver W. Stockhammer1, Han Rauwerda2, Floyd R. Wittink2, Timo M. Breit2, Annemarie H. Meijer1 and Herman P. Spaink1 1 Institute of Biology, Leiden University, Leiden, The Netherlands 2 MicroArray Department & Integrative Bioinformatics Unit, Swammerdam Institute for Life Sciences, University of Amsterdam, Amsterdam, The Netherlands Chapter 4 Abstract TRAF6 is a key player at the cross-roads of development and immunity. The analy- sis of its in vivo molecular function is a great challenge since severe developmental defects and early lethality caused by Traf6 deficiency in knock-out mice interfere with analyses of the immune response. In this study we have used a new strategy to analyse the function of Traf6 in a zebrafish-Salmonella infectious disease model. In our approach the effect of a Traf6 translation-blocking morpholino was titrated down to avoid developmental defects and the response to infection under these par- tial knock-down conditions was studied using the combination of microarray and next generation sequencing technology. Transcriptome profiling of the traf6 knock- down allowed the identification of a gene set whose responsiveness during infec- tion is highly dependent on Traf6.

Deep sequencing of the zebrafish transcriptome response to myco- bacterium infection. Mol Immunol. 2009 Sep;46(15):2918-30. Chapter 2 Abstract Novel high-throughput deep sequencing technology has dramatically changed the way that the functional complexity of transcriptomes can be studied. Here we report on the first use of this technology to gain insight into the wide range of transcrip- tional responses that are associated with an infectious disease process. Using Solexa/ Illumina’s digital gene expression (DGE) system, a tag-based transcriptome sequenc- ing method, we investigated mycobacterium-induced transcriptome changes in a model vertebrate species, the zebrafish. We obtained a sequencing depth of over 5 million tags per sample with strong correlation between replicates. Tag mapping indicated that healthy and infected adult zebrafish express over 70% of all genes represented in transcript databases. Comparison of the data with a previous mul- ti-platform microarray analysis showed that both types of technologies identified regulation of similar functional groups of genes.

  • STEAP Proteins: from Structure to Applications in Cancer Therapy
    Published OnlineFirst April 20, 2012; DOI: 10.1158/1541-7786.MCR-11-0281 Molecular Cancer Review Research STEAP Proteins: From Structure to Applications in Cancer Therapy Ines^ M. Gomes, Claudio J. Maia, and Cecília R. Santos Abstract The human 6-transmembrane epithelial antigen of prostate (STEAP) family comprises STEAP1, STEAP2, STEAP3, and STEAP4. All of these proteins are unique to mammals and share an innate activity as metallor- eductases, indicating their importance in metal metabolism. Overall, they participate in a wide range of biologic processes, such as molecular trafficking in the endocytic and exocytic pathways and control of cell proliferation and apoptosis. STEAP1 and STEAP2 are overexpressed in several types of human cancers, namely prostate, bladder, colon, pancreas, ovary, testis, breast, cervix, and Ewing sarcoma, but their clinical significance and role in cancer cells are not clear. Still, their localization in the cell membrane and differential expression in normal and cancer tissues make STEAP proteins potential candidates as biomarkers of several cancers, as well as potential targets for new immunotherapeutic strategies for disease attenuation or treatment. This review brings together the current knowledge about each STEAP protein, giving an overview of the roles of this family of proteins in human physiology and disease, and analyzes their potential as immunotherapeutic agents in cancer research.
