  • WDR1 Is a Novel EYA3 Substrate and Its Dephosphorylation Induces
    www.nature.com/scientificreports There are amendments to this paper OPEN WDR1 is a novel EYA3 substrate and its dephosphorylation induces modifcations of the cellular actin Received: 3 February 2017 Accepted: 31 January 2018 cytoskeleton Published online: 13 February 2018 Mihaela Mentel1, Aura E. Ionescu1, Ioana Puscalau-Girtu1, Martin S. Helm2,3, Rodica A. Badea1, Silvio O. Rizzoli2 & Stefan E. Szedlacsek1 Eyes absent (EYA) proteins are unusual proteins combining in a single polypeptide chain transactivation, threonine phosphatase, and tyrosine phosphatase activities. They play pivotal roles in organogenesis and are involved in a variety of physiological and pathological processes including innate immunity, DNA damage repair or cancer metastasis. The molecular targets of EYA tyrosine phosphatase activity are still elusive. Therefore, we sought to identify novel EYA substrates and also to obtain further insight into the tyrosine-dephosphorylating role of EYA proteins in various cellular processes. We show here that Src kinase phosphorylates tyrosine residues in two human EYA family members, EYA1 and EYA3. Both can autodephosphorylate these residues and their nuclear and cytoskeletal localization seems to be controlled by Src phosphorylation. Next, using a microarray of phosphotyrosine-containing peptides, we identifed a phosphopeptide derived from WD-repeat-containing protein 1 (WDR1) that is dephosphorylated by EYA3. We further demonstrated that several tyrosine residues on WDR1 are phosphorylated by Src kinase, and are efciently dephosphorylated by EYA3, but not by EYA1. The lack of phosphorylation generates major changes to the cellular actin cytoskeleton. We, therefore, conclude that WDR1 is an EYA3-specifc substrate, which implies that EYA3 is a key modulator of the cytoskeletal reorganization.

  • The Genetics of Bipolar Disorder
    Molecular Psychiatry (2008) 13, 742–771 & 2008 Nature Publishing Group All rights reserved 1359-4184/08 $30.00 www.nature.com/mp FEATURE REVIEW The genetics of bipolar disorder: genome ‘hot regions,’ genes, new potential candidates and future directions A Serretti and L Mandelli Institute of Psychiatry, University of Bologna, Bologna, Italy Bipolar disorder (BP) is a complex disorder caused by a number of liability genes interacting with the environment. In recent years, a large number of linkage and association studies have been conducted producing an extremely large number of findings often not replicated or partially replicated. Further, results from linkage and association studies are not always easily comparable. Unfortunately, at present a comprehensive coverage of available evidence is still lacking. In the present paper, we summarized results obtained from both linkage and association studies in BP. Further, we indicated new potential interesting genes, located in genome ‘hot regions’ for BP and being expressed in the brain. We reviewed published studies on the subject till December 2007. We precisely localized regions where positive linkage has been found, by the NCBI Map viewer (http://www.ncbi.nlm.nih.gov/mapview/); further, we identified genes located in interesting areas and expressed in the brain, by the Entrez gene, Unigene databases (http://www.ncbi.nlm.nih.gov/entrez/) and Human Protein Reference Database (http://www.hprd.org); these genes could be of interest in future investigations. The review of association studies gave interesting results, as a number of genes seem to be definitively involved in BP, such as SLC6A4, TPH2, DRD4, SLC6A3, DAOA, DTNBP1, NRG1, DISC1 and BDNF.

Received May 30, 2018; Accepted August 23, 2018; Epub December 1, 2018; Published December 15, 2018 Abstract: WDR1, an activator of cofilin-mediated actin depolymerization, is involved in various actin-dependent processes of living cells including cell migration and cytokinesis. Recently, several studies have found that WDR1 is dysregulated in several types of cancer and is associated with cancer metastasis. However, its role in hepatocellular carcinoma (HCC) remains unknown. In this study, we found that WDR1 expression was aberrantly upregulated at the mRNA and protein levels in HCC cell lines and HCC tissues. WDR1 overexpression was highly correlated with tumor aggressive phenotypes such as capsulation formation, microvascular invasion (MVI), tumor node metastasis (TNM) stage, and was an independent poor prognostic factor for overall survival (OS) and disease-free survival (DFS) for HCC patients after curative surgery. Furthermore, WDR1 overexpression significantly promoted HCC cell migration, invasion and proliferation. In contrast, WDR1 downregulation inhibited HCC cell migration, invasion and prolifera- tion. Conclusion: This study indicates that WDR1 could be used as a new useful prognostic marker and may be a potential therapeutic target for HCC.

  • WDR1 Colocalizes with ADF and Actin in the Normal and Noise-Damaged Chick Cochlea
    THE JOURNAL OF COMPARATIVE NEUROLOGY 448:399–409 (2002) WDR1 Colocalizes With ADF and Actin in the Normal and Noise-Damaged Chick Cochlea SEUNG-HA OH,1,2 HENRY J. ADLER,3 YEHOASH RAPHAEL,1,2 AND MARGARET I. LOMAX1* 1Kresge Hearing Research Institute, Department of Otolaryngology-Head and Neck Surgery; The University of Michigan Medical School, Ann Arbor, Michigan 48109-0506 2Department of Otolaryngology-Head and Neck Surgery, Seoul National University College of Medicine, 110-744 Seoul, Korea 3NIDCD/NIH, Bethesda, Maryland 20892 ABSTRACT Auditory hair cells of birds, unlike hair cells in the mammalian organ of Corti, can regenerate following sound-induced loss. We have identified several genes that are upregu- lated following such an insult. One gene, WDR1, encodes the vertebrate homologue of actin-interacting protein 1, which interacts with actin depolymerization factor (ADF) to enhance the rate of actin filament cleavage. We examined WDR1 expression in the develop- ing, mature, and noise-damaged chick cochlea by in situ hybridization and immunocytochem- istry. In the mature cochlea, WDR1 mRNA was detected in hair cells, homogene cells, and cuboidal cells, all of which contain high levels of F-actin. In the developing inner ear, WDR1 mRNA was detected in homogene cells and cuboidal cells by embryonic day 7, in the undifferentiated sensory epithelium by day 9, and in hair cells at embryonic day 16. We also demonstrated colocalization of WDR1, ADF, and F-actin in all three cell types in the normal and noise-damaged cochlea. Immediately after acoustic overstimulation, WDR1 mRNA was seen in supporting cells. These cells contribute to the structural integrity of the basilar papilla, the maintenance of the ionic barrier at the reticular lamina, and the generation of new hair cells.

However, linking common variants to genes that are causal for CKD etiology remains challenging. By adapting self-transcribing active regulatory region sequencing, we evaluated the effect of genetic variation on DNA regulatory elements (DREs). Variants in linkage with the CKD-associated single-nucleotide polymorphism rs11959928 were shown to affect DRE function, illustrating that genes regulated by DREs colocalizing with CKD-associated variation can be dysregulated and therefore, considered as CKD candidate genes. To identify target genes of these DREs, we used circular chro- mosome conformation capture (4C) sequencing on glomerular endothelial cells and renal tubular epithelial cells. Our 4C analyses revealed interactions of CKD-associated susceptibility regions with the transcriptional start sites of 304 target genes. Overlap with multiple databases confirmed that many of these target genes are involved in kidney homeostasis.
