Two New Lines of Genetically Altered Mice Developed to Study Cancer

NIEHS researchers produced two lines of genetically altered mice that have a significant impact on the study of cancer development. Research with these mice showed that removal of two genes, COX-1 and COX-2, lead to a significant decrease in development of colon, skin, and intestinal cancers in laboratory animals.
