Fingering carcinogens with genetic evidence

Article Abstract:

Genetic fingerprinting will become a valuable tool in environmental health research as researchers use the technique to specify which agents or substances cause specific forms of cancer. While cancer research has singled out defects in the gene ras and p53 as determinants of cancer occurence, the type of defects found in the ras and p53 determines what kind of cancer occurs. Researchers are now correlating specific defects in the genes with specific substances that will be useful in determining the immediate effects of pollutants and their tolerable levels.

Unraveling cancer risk: with cellular and molecular tools

Article Abstract:

Environmental risk assessments, in the near future, may provide a clearer picture with the help of advances in genetics and molecular biology to bring in some of the details. New technologies in genetics and molecular biology are also changing the methods by which risk assessments are conducted. Previously, tests rely more on general principles and experience and not on specific chemicals causing cancer or other adverse effects. The advancements are specially directed on ways to strengthen assessments of the carcinogenicity of compounds in the environment.

Unraveling cancer risk with cellular and molecular tools

Article Abstract:

Advances in genetics and molecular biology are expected to improve the soundness of future risk assessments and explain health risks caused by environmental contaminants. A major part of the new genetic and molecular biologic developments for risk assessments concentrates on how to strengthen assessments of the carcincogenity of compounds.
