  1. 26. Studies on adult stem cells

    Författare :Konstantinos Meletis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : While our bodies are aging, in quite a few tissues, new cells are born every day, till the day we die. As you are reading this sentence, there is perhaps a new neuron born in your brain (and some are dying). LÄS MER

  3. 27. Radiation response in human cells : DNA damage formation, repair and signaling

    Författare :Ann-Sofie Gustafsson; Bo Stenerlöw; Andrzej Wojcik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER

  4. 28. Forkhead Genes in Mammalian Development

    Författare :Henrik Landgren; Göteborgs universitet; []
    Nyckelord :Development; Forkhead;

    Sammanfattning : This thesis concerns aspects of Forkhead gene biology and it’s relation to mammalian development. Genes from three subclasses are discussed, Foxj3, Foxf1 and f2, and Foxe3. LÄS MER

  5. 29. Selenium in mammalian thioredoxin reductase

    Författare :Liangwei Zhong; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Thioredoxin reductase (TrxR) is a major enzyme in regulating intracellular redox status. The enzyme from several mammalian tissues has been purified, showing higher molecular weight and a much broader substrate specificity than E. coli TrxR, but the structural basis of these properties remained unknown.

  7. 30. On the Regulation of Ornithine Decarboxylase

    Författare :Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

    Sammanfattning : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. LÄS MER
