Nancy Hopkins, an American molecular biologist, is the Amgen, Inc. Professor of Biology at the Massachusetts Institute of Technology. She is a member of the National Academy of Sciences, the Institute of Medicine of the National Academy, and the American Academy of Arts and Sciences. She is known for her research identifying genes required for zebrafish development, and for her earlier research on gene expression in the bacterial virus, lambda, and on mouse RNA tumor viruses. She is also known for her work promoting equality of opportunity for women scientists in academia.
Hopkins received her BA from Radcliffe College in 1964, and earned her PhD from the Department of Molecular Biology and Biochemistry at Harvard University in 1971, where she worked with Professor Mark Ptashne. With Ptashne she identified the operator sites on DNA to which the lambda repressor binds to control early gene expression and hence the viral life cycle. As a postdoctoral fellow of Nobel Laureate James D. Watson and Robert Pollack at the Cold Spring Harbor Lab she worked on DNA tumor viruses and cell biology, discovering that cells whose nucleus had been removed were able to re-establish normal morphology.
She joined the MIT faculty in the Center for Cancer Research in 1973 as an assistant professor and switched to work on RNA tumor viruses. She identified viral genes that determine host range and the type and severity of cancers mouse retroviruses cause, including importantly the capsid protein p30 and transcriptional elements that came to be known as enhancers. After a sabbatical in the lab of Nobel laureate Christiane Nusslein-Volhard in 1989, Hopkins switched fields to develop molecular technologies for working with zebrafish. With her postdoctoral fellow Shuo Lin, graduate students Adam Amsterdam and Nick Gaiano, and others in her lab she developed an efficient method for large-scale insertional mutagenesis in the fish. Using this technique her lab carried out a large genetic screen that identified and cloned 25% of the genes that are essential for a fertilized egg to develop into a free-swimming zebrafish larva. Among the genes identified was an unexpected class of genes which when mutated predispose fish to get cancer, and a set of genes that cause fish to develop cystic kidney and which overlap with genes that cause cystic kidney disease in humans.
