Michael Howard Wigler (born September 3, 1947 in New York) is an American molecular biologist who has directed a laboratory at Cold Spring Harbor Laboratory since 1978 and is a member of the National Academy of Sciences. He is best known for developing methods to genetically engineer animal cells and his contributions to cancer, genomics and autism genetics.
Wigler graduated from Princeton University in 1970, majoring in mathematics, and in 1978 received his PhD from Columbia University in microbiology, and has spent the remainder of his career at Cold Spring Harbor Laboratory (CSHL).
Beginning in the late 1970s, at Columbia University, Wigler, Richard Axel and Saul Silverstein developed methods for engineering animal cells. These methods are the basis for many discoveries in mammalian genetics, and the means for producing protein therapeutics such as those used to treat heart disease, cancer and strokes.
After moving to CSHL, Wigler continued his studies of gene transfer into mammalian cells, exploring the integration of foreign DNA and its stability of expression in host cells, demonstrating the inheritance of DNA methylation patterns, and isolating the first vertebrate genes, and first human oncogenes, using DNA transfer and genetic selection. His laboratory was among the group that first showed the involvement of members of the RAS gene family in human cancer, and that point mutations can activate the oncogenic potential of cellular genes.
Wigler’s laboratory was the first to demonstrate that some regulatory pathways have been so conserved in evolution that yeast can be used as a host to study the function of mammalian genes and in particular genes involved in signal transduction pathways and cancer. This led to deep insights into RAS function, eventually solving the RAS biochemical pathway in yeasts and humans, and demonstrating the multifunctional nature of this important oncogene. During this period Wigler's lab published the first use of epitope tagging for protein purification.
