    A Helical Bundle in the N-terminal Domain of the BLM Helicase Mediates Dimer and Potentially Hexamer Formation.
    J Biol Chem 2017 Feb 22. Epub 2017 Feb 22.
    Northwest A&F University;
    Helicases play a critical role in processes such as replication or recombination by unwinding double-stranded DNA; mutations of these genes can therefore have devastating biological consequences. In human, mutations in genes of three members of the RecQ family helicases (blm, wrn and recq4) give rise to three strikingly distinctive clinical phenotypes: Bloom syndrome, Werner syndrome and Rothmund-Thomson syndrome, respectively. However, the molecular basis for these varying phenotypic outcomes is unclear, in part because a full mechanistic description of helicase activity is lacking. Read More

    Is There an Association Between Hemoglobin A1C and Deep Postoperative Infection After TKA?
    Clin Orthop Relat Res 2017 Jan 23. Epub 2017 Jan 23.
    Department of Orthopaedic Surgery, University of Virginia Health System, PO Box 800159 HSC, Charlottesville, VA, 22908, USA.
    Background: Despite substantial research into the use of glycemic markers to stratify infection risk in patients with diabetes mellitus, there is little evidence to support a perioperative hemoglobin A1c (HbA1c) level associated with an increased risk of deep postoperative infection after TKA.

    Questions/purposes: (1) Is there an association between perioperative HbA1c level in patients with diabetes and deep postoperative infection after primary TKA? (2) Is the perioperative HbA1c level in patients with diabetes a useful test as an independent predictor for postoperative infection after TKA?

    Methods: We queried the PearlDiver Patient Records Database Humana dataset for patients who underwent primary TKA. This is a for-fee insurance patient-records database that contains records for more than 20 million patients with orthopaedic diagnoses from 2007 to the second quarter of 2015. Read More

    Virtual three-dimensional placentoscopy: a new approach to assess residual anastomoses following laser photocoagulation in twin-to-twin transfusion syndrome.

    Pyometra and Pregnancy with Herlyn-Werner-Wunderlich Syndrome.
    Rev Bras Ginecol Obstet 2016 Dec 21;38(12):623-628. Epub 2016 Dec 21.
    Department of Obstetrics and Gynecology and Department of Maternal Fetal Medicine, Hospital Dr. José de Almeida, Lisbon, Portugal.
    We describe a Herlyn-Werner-Wunderlich syndrome (HWWS) patient with previous history of infertility who got pregnant without treatment and presented a pyometra in the contralateral uterus throughout the gestational period, despite multiple antibiotic treatments. Due to the uterus' congenital anomaly and the possibility of ascending infection with subsequent abortion, this pregnancy was classified as high-risk. We believe that the partial horizontal septum in the vagina may have contributed to the closure of the gravid uterus cervix, thus ensuring that the pregnancy came to term, with an uneventful vaginal delivery.

A total of 3,741 unique base pair-level variants were identified, across 17,605 potential mutation sites. Read More

    The Werner Syndrome Helicase Coordinates Sequential Strand Displacement and FEN1-Mediated Flap Cleavage during Polymerase δ Elongation.
    Mol Cell Biol 2017 Feb 19;37(3). Epub 2017 Jan 19.
    Department of Molecular Microbiology and Immunology, Institute for Genetic Medicine, Keck School of Medicine, University of Southern California, Los Angeles, California, USA
    The Werner syndrome protein (WRN) suppresses the loss of telomeres replicated by lagging-strand synthesis by a yet to be defined mechanism. Here, we show that whereas either WRN or the Bloom syndrome helicase (BLM) stimulates DNA polymerase δ progression across telomeric G-rich repeats, only WRN promotes sequential strand displacement synthesis and FEN1 cleavage, a critical step in Okazaki fragment maturation, at these sequences. Helicase activity, as well as the conserved winged-helix (WH) motif and the helicase and RNase D C-terminal (HRDC) domain play important but distinct roles in this process. Read More

    WRN-targeted therapy using inhibitors NSC 19630 and NSC 617145 induce apoptosis in HTLV-1-transformed adult T-cell leukemia cells.
    J Hematol Oncol 2016 Nov 9;9(1):121. Epub 2016 Nov 9.
    Department of Pathology and Laboratory Medicine, Center for Viral Oncology, University of Kansas Medical Center, 3901 Rainbow Boulevard, Kansas City, KS, 66160, USA.
    Background: Human T-cell leukemia virus type 1 (HTLV-1) infection is associated with adult T-cell leukemia/lymphoma (ATLL), a lymphoproliferative malignancy with a dismal prognosis and limited therapeutic options. Recent evidence shows that HTLV-1-transformed cells present defects in both DNA replication and DNA repair, suggesting that these cells might be particularly sensitive to treatment with a small helicase inhibitor. Because the "Werner syndrome ATP-dependent helicase" encoded by the WRN gene plays important roles in both cellular proliferation and DNA repair, we hypothesized that inhibition of WRN activity could be used as a new strategy to target ATLL cells.

    Class I Histone Deacetylase HDAC1 and WRN RECQ Helicase Contribute Additively to Protect Replication Forks upon Hydroxyurea-induced Arrest.
    J Biol Chem 2016 Nov 26;291(47):24487-24503. Epub 2016 Sep 26.
    From the Department of Pathology and
    The WRN helicase/exonuclease is mutated in Werner syndrome of genomic instability and premature aging. WRN-depleted fibroblasts, although remaining largely viable, have a reduced capacity to maintain replication forks active during a transient hydroxyurea-induced arrest. A strand exchange protein, RAD51, is also required for replication fork maintenance, and here we show that recruitment of RAD51 to stalled forks is reduced in the absence of WRN. Read More

    Atypical progeroid syndrome (APS), including atypical Werner syndrome (AWS), is a disorder of premature ageing caused by mutation of the lamin A gene, the same causal gene involved in Hutchinson-Gilford syndrome (HGS). We previously reported the first Japanese case of APS/AWS with a LMNA mutation (p.D300N). Read More

    Tibial hemimelia is a rare congenital limb deficiency which is characterised by a hypoplastic/aplastic tibia. It actually represents a spectrum of anomalies, ranging from mild hypoplasia of the tibia to total absence of the tibia. Several classifications based on radiological description exist in the literature. Read More

    Werner's syndrome (WS) is an autosomal recessive genetic disorder caused by loss of function mutation in wrn and is a useful model of premature in vivo ageing. Cellular senescence is a plausible causal mechanism of mammalian ageing and, at the cellular level, WS fibroblasts show premature senescence resulting from a combination of telomeric attrition and replication fork stalling. Over 90% of WS fibroblast cultures achieve <20 population doublings (PD) in vitro compared to wild type human fibroblast cultures. Read More
