6. Selective Retention of β-Carbolines and 7,12-Dimethylbenz[a]anthracene in the Brain : Role of Neuromelanin and Cytochrome P450 for Toxicity
Sammanfattning : The ß-carbolines norharman and harman structurally resemble the synthetic compound 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) that is known for its ability to damage neuromelanin-containing dopaminergic neurons of the substantia nigra and thereby induce parkinsonism. MPTP is, however, not normally present in the environment whereas the ß-carbolines are present in cooked food and tobacco smoke. LÄS MER
7. Regulation of dioxin receptor function by the Hsp90 chaperone complex
Sammanfattning : In mammals the basic helix-loop-helix/Per-Arnt-Sim (bHLH/PAS) family of transcription factors includes the dioxin receptor which is a ligand-dependent transcription factor which mediates biological effects of environmental pollutants such as 2,3,7,8-tetrachlorodibenzo-rho-dioxin (dioxin). In the absence of ligand, the dioxin receptor is associated with the molecular chaperone Hsp90 and two Hsp90-interacting proteins, the co-chaperone p23 and an immunophilin-like protein XAP2. LÄS MER
8. Towards Personalized Cancer Therapy : New Diagnostic Biomarkers and Radiosensitization Strategies
Sammanfattning : This thesis focuses on the evaluation of biomarkers for radio-immunodiagnostics and radio-immunotherapy and on radiosensitization strategies after HSP90 inhibition, as a step towards more personalized cancer medicine. There is a need to develop new tracers that target cancer-specific biomarkers to improve diagnostic imaging, as well as to combine treatment strategies to potentiate synergistic effects. LÄS MER
9. Regulation of transcription factors by XAP-2 : a member of the Hsp90 chaperone complex
Sammanfattning : The AhR belongs to the bHLH/PAS family of transcription factors, which mediates biological effects of environmental pollutants such as 2,3,7,8-tetrachlorodibenzo-rho-dioxin (TCDD). In the absence of ligand the AhR is located in the cytoplasmatic compartment of the cell associated with the molecular chaperone Hsp90, p23 and a member of the immunophilin family of proteins, XAP-2.

10. Mechanism of conditional regulation of the bHLH/PAS dioxin receptor
Sammanfattning : The intracellular dioxin receptor is a bHLH/PAS protein which mediates signal transduction by dioxin and upon heterodimerisation with the bHLH/PAS partner factor Arnt, functions as a ligand-activated transcription factor by binding to specific xenobiotic response elements in promoters of target genes. Although the physiological function of the dioxin receptor and the nature of a possible physiological ligand are presently not known, targeted disruption of the mouse dioxin receptor gene has indicated that the receptor may play an important role in hepatic development.
