  3. 17. Polyamines are involved in the regulation of S phase and DNA synthesis

    Författare :Kersti Alm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurfysiologi; Animal physiology; cell cycle regulation; p53; DNA strand breaks; replicon organization; topoisomerase II;

    Sammanfattning : Our research group has previously shown that treatment with the polyamine biosynthesis inhibitors a-difluoromethylornithine (DFMO) or amidinoindan-1-one 2´-amidinohydrazone (CGP 48664) inhibited S phase progression before any other cell cycle phase was affected. This study was undertaken to further investigate the role of polyamines in the regulation of S phase progression and DNA synthesis. LÄS MER

  7. 20. Mitochondrial plasmids, genetic conflicts and sex-determination in Silene vulgaris

    Författare :Helene Andersson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene vulgaris; sex-determination; mitochondrial plasmids; genetic conflicts; Botanik; Botany;

    Sammanfattning : Plants like all other eukaryotic organisms carry most of their DNA in the nucleus. In addition, plants also have both chloroplasts and mitochondria that contain their own genetic material. The genomes in chloroplasts and mitochondria control certain vital processes, but most often the organelles act under strict nuclear control. LÄS MER
