    Preprint: Please note that this article has not completed peer review. The expression patterns and the prognostic roles of PTPN family members in digestive tract cancers CURRENT STATUS: UNDER REVIEW Jing Chen The First Affiliated Hospital of China Medical University Xu Zhao Liaoning Vocational College of Medicine Yuan Yuan The First Affiliated Hospital of China Medical University Jing-jing Jing The First Affiliated Hospital of China Medical University [email protected] Author ORCiD: https://orcid.org/0000-0002-9807-8089 DOI: 10.21203/rs.3.rs-19689/v1 SUBJECT AREAS Cancer Biology KEYWORDS PTPN family members, digestive tract cancers, expression, prognosis, clinical features 1 Abstract Background Non-receptor protein tyrosine phosphatases (PTPNs) are a set of enzymes involved in the tyrosyl phosphorylation. The present study intended to clarify the associations between the expression patterns of PTPN family members and the prognosis of digestive tract cancers. Method Expression profiling of PTPN family genes in digestive tract cancers were analyzed through ONCOMINE and UALCAN. Gene ontology enrichment analysis was conducted using the DAVID database. The gene–gene interaction network was performed by GeneMANIA and the protein–protein interaction (PPI) network was built using STRING portal couple with Cytoscape. Data from The Cancer Genome Atlas (TCGA) were downloaded for validation and to explore the relationship of the PTPN expression with clinicopathological parameters and survival of digestive tract cancers. Results Most PTPN family members were associated with digestive tract cancers according to Oncomine, Ualcan and TCGA data. For esophageal carcinoma (ESCA), expression of PTPN1, PTPN4 and PTPN12 were upregulated; expression of PTPN20 was associated with poor prognosis.

  • The Regulatory Roles of Phosphatases in Cancer
    Oncogene (2014) 33, 939–953 & 2014 Macmillan Publishers Limited All rights reserved 0950-9232/14 www.nature.com/onc REVIEW The regulatory roles of phosphatases in cancer J Stebbing1, LC Lit1, H Zhang, RS Darrington, O Melaiu, B Rudraraju and G Giamas The relevance of potentially reversible post-translational modifications required for controlling cellular processes in cancer is one of the most thriving arenas of cellular and molecular biology. Any alteration in the balanced equilibrium between kinases and phosphatases may result in development and progression of various diseases, including different types of cancer, though phosphatases are relatively under-studied. Loss of phosphatases such as PTEN (phosphatase and tensin homologue deleted on chromosome 10), a known tumour suppressor, across tumour types lends credence to the development of phosphatidylinositol 3--kinase inhibitors alongside the use of phosphatase expression as a biomarker, though phase 3 trial data are lacking. In this review, we give an updated report on phosphatase dysregulation linked to organ-specific malignancies.

  • Identification and Expression of the Family of Classical Protein-Tyrosine Phosphatases in Zebrafish
    Identification and Expression of the Family of Classical Protein-Tyrosine Phosphatases in Zebrafish Mark van Eekelen1, John Overvoorde1, Carina van Rooijen1, Jeroen den Hertog1,2* 1 Hubrecht Institute, KNAW and University Medical Center Utrecht, Utrecht, The Netherlands, 2 Institute of Biology Leiden, Leiden University, Leiden, The Netherlands Abstract Protein-tyrosine phosphatases (PTPs) have an important role in cell survival, differentiation, proliferation, migration and other cellular processes in conjunction with protein-tyrosine kinases. Still relatively little is known about the function of PTPs in vivo. We set out to systematically identify all classical PTPs in the zebrafish genome and characterize their expression patterns during zebrafish development. We identified 48 PTP genes in the zebrafish genome by BLASTing of human PTP sequences. We verified all in silico hits by sequencing and established the spatio-temporal expression patterns of all PTPs by in situ hybridization of zebrafish embryos at six distinct developmental stages. The zebrafish genome encodes 48 PTP genes. 14 human orthologs are duplicated in the zebrafish genome and 3 human orthologs were not identified. Based on sequence conservation, most zebrafish orthologues of human PTP genes were readily assigned. Interestingly, the duplicated form of ptpn23, a catalytically inactive PTP, has lost its PTP domain, indicating that PTP activity is not required for its function, or that ptpn23b has lost its PTP domain in the course of evolution. All 48 PTPs are expressed in zebrafish embryos. Most PTPs are maternally provided and are broadly expressed early on. PTP expression becomes progressively restricted during development. Interestingly, some duplicated genes retained their expression pattern, whereas expression of other duplicated genes was distinct or even mutually exclusive, suggesting that the function of the latter PTPs has diverged.

    European Journal of Human Genetics (2015) 23, 1171–1175 & 2015 Macmillan Publishers Limited All rights reserved 1018-4813/15 www.nature.com/ejhg ARTICLE Deletion of protein tyrosine phosphatase, non-receptor type 4 (PTPN4) in twins with a Rett syndrome-like phenotype Sarah L Williamson1, Carolyn J Ellaway1,2, Greg B Peters2,3, Gregory J Pelka4, Patrick PL Tam4,5 and John Christodoulou*,1,2 Rett syndrome (RTT), a neurodevelopmental disorder that predominantly affects females, is primarily caused by variants in MECP2. Variants in other genes such as CDKL5 and FOXG1 are usually associated with individuals who manifest distinct phenotypes that may overlap with RTT. Individuals with phenotypes suggestive of RTT are typically screened for variants in MECP2 and then subsequently the other genes dependent on the specific phenotype. Even with this screening strategy, there are individuals in whom no causative variant can be identified, suggesting that there are other novel genes that contribute to the RTT phenotype. Here we report a de novo deletion of protein tyrosine phosphatase, non-receptor type 4 (PTPN4) in identical twins with a RTT-like phenotype. We also demonstrate the reduced expression of Ptpn4 in a Mecp2 null mouse model of RTT, as well as the activation of the PTPN4 promoter by MeCP2. Our findings suggest that PTPN4 should be considered for addition to the growing list of genes that warrant screening in individuals with a RTT-like phenotype.

However, recurrence and chemoresistance are critical issues for breast cancer patients. PTPN4, a new potential therapeutic target, has not been studied sufficiently in breast cancer, and the potential role of PTPN4 in the prognosis of breast cancer patients is still unknown. In our study, data from 140 invasive breast cancer pa- tients were retrospectively collected to identify the association between PTPN4 expression and clinical outcomes of these patients. The expressions of PTPN4 were detected by immunohistochemical analysis. Breast hyperplasia tissues showed higher expression of PTPN4. We found that PTPN4 expression was lower in breast cancer patients with relapse than in patients without relapse. Patients with an increased PTPN4 level had a significantly longer relapse-free survival and overall survival time. Decreased PTPN4 expression was an independent factor associated with relapse-free survival and overall survival, as shown by multivariate Cox regression analysis. The study found that PTPN4 is an attractive prognostic biomarker for predicting the clinical outcome and effective disease manage- ment of breast cancer patients.

  • Genome-Wide Association Study Reveals Genetic Architecture of Eating Behavior in Pigs and Its Implications for Humans Obesity by Comparative Mapping
    Genome-Wide Association Study Reveals Genetic Architecture of Eating Behavior in Pigs and Its Implications for Humans Obesity by Comparative Mapping Duy Ngoc Do1, Anders Bjerring Strathe1,2, Tage Ostersen2, Just Jensen3, Thomas Mark1, Haja N Kadarmideen1* 1 Department of Veterinary Clinical and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, Frederiksberg, Denmark, 2 Danish Agriculture and Food Council, Pig Research Centre, Copenhagen, Denmark, 3 Aarhus University, Department of Molecular Biology and Genetics, Tjele, Denmark Abstract This study was aimed at identifying genomic regions controlling feeding behavior in Danish Duroc boars and its potential implications for eating behavior in humans. Data regarding individual daily feed intake (DFI), total daily time spent in feeder (TPD), number of daily visits to feeder (NVD), average duration of each visit (TPV), mean feed intake per visit (FPV) and mean feed intake rate (FR) were available for 1130 boars. All boars were genotyped using the Illumina Porcine SNP60 BeadChip. The association analyses were performed using the GenABEL package in the R program. Sixteen SNPs were found to have moderate genome-wide significance (p,5E-05) and 76 SNPs had suggestive (p,5E-04) association with feeding behavior traits. MSI2 gene on chromosome (SSC) 14 was very strongly associated with NVD. Thirty-six SNPs were located in genome regions where QTLs have previously been reported for behavior and/or feed intake traits in pigs. The regions: 64–65 Mb on SSC 1, 124–130 Mb on SSC 8, 63–68 Mb on SSC 11, 32–39 Mb and 59–60 Mb on SSC 12 harbored several signifcant SNPs.

Several groups have done expression profile of metastatic can accurately identify metastatic cells and aggressive tumor in vitro behavior. To find new markers, serial analysis of gene primary PTC or model systems to identify clinical outcome expression (SAGE) was done on three samples from the same markers (5, 6). Although these approaches could identify useful patient: normal thyroid tissue, primary PTC, and a PTC lymph prognostic markers, they do not directly identify gene expression node metastasis. This genomewide expression analysis iden- changes that occur in the metastatic cells. Identification of genes tified 31 genes expressed in lymph node metastasis, but not that are consistently expressed in metastatic PTC cells could yield in the primary tumor. Eleven genes were evaluated by useful biomarkers. These markers have potential prognostic use quantitative real-time reverse transcription-PCR (qPCR) on and may also help identify occult metastatic cells in lymph node independent sets of matched samples to find genes that were biopsies.
