  1. 1. Pathology of dNTP dysregulation

    Författare :Phong Tran; Andrei Chabes; Erik Johansson; Ola Hammarsten; Umeå universitet; []
    Nyckelord :dNTP metabolism; DNA replication; mutation rate; cancer; heart development; RNR; SAMHD1; Rrm1; Samhd1; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Deoxyribonucleoside triphosphates (dNTPs) are precursors for DNA replication and repair. Mammalian cells have two distinct biosynthesis pathways to supply dNTPs: de novo and salvage pathways. LÄS MER

  3. 2. Regulation of ribonucleotide reductase and the role of dNTP pools in genomic stability in yeast Saccharomyces cerevisiae

    Författare :Olga Tsaponina; Andrei Chabes; Ola Hammarsten; Umeå universitet; []
    Nyckelord :ribonucleotide reductase; dNTP; genome stability;

    Sammanfattning : Every living organism is programmed to reproduce and to pass genetic information to descendants. The information has to be carefully copied and accurately transferred to the next generation.  Therefore organisms have developed the network of conserved mechanisms to survey the protection and precise transfer of the genetic information.

  4. 3. Structure of eukaryotic DNA polymerase epsilon and lesion bypass capability

    Författare :Nasim Sabouri; Erik Johansson; Lars Thelander; Ola Hammarsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA polymerase epsilon; DNA replication; Okazaki fragment; Translesion synthesis; DNA lesion; dNTP; Biochemistry; Biokemi;

    Sammanfattning : To transfer the information in the genome from mother cell to daughter cell, the DNA replication must be carried out only once and with very high fidelity prior to every cell division. In yeast there are several different DNA polymerases involved in DNA replication and/or DNA repair. LÄS MER

  5. 4. Targeting the nucleotide metabolism of the mammalian pathogen Trypanosoma brucei

    Författare :Munender Vodnala; Anders Hofer; Arne Holmgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Trypanosoma brucei; adenosine kinase; thymidine kinase; methylthioadenosine phosphorylase; mouser ribonucleotide reductase; E. coli ribonucleotide reductase; RNR; Ara-A; F-Ara-A; dNTP; NTP; doexynucleotide metabolism; nucleosides; nucleoside kinases; allosteric regulation; biologisk kemi; biological chemistry;

    Sammanfattning : Trypanosoma brucei causes African sleeping sickness in humans and Nagana in cattle. There are no vaccines available against the disease and the current treatment is also not satisfactory because of inefficacy and numerous side effects of the used drugs.T. LÄS MER

  7. 5. dNTPs : the alphabet of life

    Författare :Dinesh Kumar; Andrei Chabes; Britt-Marie Sjöberg; Umeå universitet; []
    Nyckelord :ribonucleotide reductase; dNTP pools; s-phase checkpoint; mutagenesis; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : From microscopic bacteria to the giant whale, every single living organism on Earth uses the same language of life: DNA. Deoxyribonucleoside triphosphates––dNTPs (dATP, dTTP, dGTP, and dCTP)––are the building blocks of DNA and are therefore the “alphabet of life”. LÄS MER
