Chemical carcinogensis, prevention and risk assessment
The overall goal is to improve the basis of risk assessment of chemical carcinogens.
The CRAB-project investigates a novel approach to cancer risk assessment which could greatly assist risk assessors with the management of large textual data and aid knowledge discovery. We develop TM technology for the needs of cancer research and risk assessment with the aim to integrate this technology in a practical tool which can assist risk assessors and researchers in their work and contribute to effective management of health risks in the future.
In other projects we analyze sex differences in response to carcinogens and the effects of mixtures of polycyclic aromatic hydrocarbons (PAHs) on cellular signaling. The goal of the projects is to improve the scientific base for risk assessment. Statins have been shown to have anticancer effects and to sensitize tumor cells to cytostatic drugs. Our data show that statins regulate nuclear Akt activity via P2X7 receptors. The regulation of Akt/PTEN tumor suppressor pathway is studied.
