    • In order to investigate the molecular basis of variation in response to ionising radiation (IR) in radiotherapy patients, we have studied the expression of several genes involved in DNA double-strand break repair pathways in fibroblast cell lines. Ten lines were established from skin biopsies of cancer patients with different normal-tissue reactions to IR, and 3 from a control individual. For all 10 test cell lines, the cellular radiosensitivity was also known. Using Western blots we measured, in non-irradiated cells, the basal expression levels of ATM, Rad1 and Hus1, involved in the control of cellular DNA damage checkpoints, together with DNA-PKcs, Ku70, Ku80; XRCC4, ligaseIV and Rad51, involved in radiation- induced DSB repair. We also analysed the in vitro enzymatic activities, under non-irradiated conditions, of the DNA-PK and XRCC4/ligaseIV complexes. The levels of expression of the different proteins were similar in all the cell lines, but the activities of the DNA-PK and XRCC4/ligaseIV complexes showed some differences. These differences did not correlate with either the normal tissue response of the patient in vivo or with cellular radiation sensitivity in vitro. The activity differences of these enzyme complexes, therefore, do not account for the variation of responses seen between patients.

  • Double aortic arch masquerading as asthma for thirty years
  • 2002
  • Ingår i: Respiration. - : S. Karger AG. - 0025-7931 .- 1423-0356. ; 69:1, s. 92-95
  • Tidskriftsartikel (refereegranskat)abstract
    • A case of a 30-year-old woman with a double-barrelled aorta misdiagnosed as asthma is presented. The patient was significantly improved after surgical treatment but a degree of airway symptoms persisted. She was further investigated and diagnosed with tracheomalacia. The paediatric experience with managing tracheomalacia is briefly reviewed and recommendations for the treatment of the rare adult cases are made. Our report emphasises the importance of early diagnosis and treatment of aortic arch abnormalities.
