The National Institute of Environmental Health Sciences (NIEHS) is one of 27 Institutes and Centers of the National Institutes of Health (NIH),which is a component of the Department of Health and Human Services (DHHS). NIEHS is located on 375 acres (1.52 km2) in Research Triangle Park (RTP). The mission of the NIEHS is to reduce the burden of human illness and disability by understanding how the environment influences the development and progression of human disease. NIEHS focuses on basic science, disease-oriented research, global environmental health, and multidisciplinary training for researchers. NIEHS researchers and grantees have shown the deadly effects of asbestos exposure, the developmental impairment of children exposed to lead and the health effects of urban pollution. This is the laboratory of the 1994 co-recipient of the Nobel Prize in medicine, Dr. Martin Rodbell. Here scientists that same year had a key role in identifying the first breast cancer gene, BRCA1, and, in 1995, identified a gene that suppresses prostate cancer.
