22. Nucleic Acids as Drug Targets -Interactions of Platinum Complexes, Polyamines, and siRNA with DNA and RNA Models
Abstract : Drugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. READ MORE

23. On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer
Abstract : Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA.

24. Markers predicting sensitivity to polyamine depletion in human breast cancer cell lines
Abstract : In spite of different treatment strategies today, breast cancer mortality is still high and new treatments are therefore needed. Potential new treatments can be found among the polyamine analogues. Polyamine analogues can be used in cancer treatment as cancer cells have a higher requirement for polyamines than the surrounding healthy tissue. READ MORE

25. Chromatin structure in liver nuclei of Atlantic salmon after activation of the vitellogenin gene by 17-β estradiol
Abstract : The present investigations were initiated to study changes in hepatic nucleiduring the 17-ß estradiol induced synthesis of vitellogenin in Atlantic salmon(Salmo salar). As a model system for the naturally maturing fish parr andsmoltified salmon were used and treated with the steroid hormone. READ MORE
