Study: Prion diseases might be prevented

UK scientists have made a major scientific advance by establishing proof of principle that the development of prion disease can be prevented in mice using monoclonal antibodies (mAbs). The work lays the foundation for further research to explore the potential of mAbs to treat specific prion diseases such as CJD and vCJD. The work is published today (6 March 2003) in Nature.

New drug could help target cancer cells with deadly accuracy

Researchers in Britain have developed a drug they say could revolutionize the effectiveness of radiation on cancer. Radiotherapy is used to destroy cancer cells by zapping their DNA, thus disrupting their ability to function and reproduce. But like other cells in the body, cancer cells have a sort of DNA repair kit that can minimize these effects. The new drug disables the DNA repair process and allows radiotherapy to target tumors with “deadly accuracy.”
