Robert Darnell is an American Neuro-Oncologist and neuroscientist who is the Founding Director and Chief Executive Officer of the New York Genome Center, the Robert and Harriet Heilbrunn Professor of Cancer Biology at The Rockefeller University,[1] and an Investigator of the Howard Hughes Medical Institute. His research into rare autoimmune brain diseases led to the invention of the HITS-CLIP method to study RNA regulation, and he is developing new ways to explore the regulatory portions—known as the “dark matter”—of the human genome.[2]

At The Rockefeller University Darnell is Head of the Laboratory of Molecular Neuro-Oncology,[3] and Senior Physician at the Rockefeller University Hospital,[4] has been an HHMI Investigator since 1992,[5] and an Adjunct Attending Neuro-Oncologist at the Memorial Sloan-Kettering Cancer Center. He was named to the New York Genome Center position on November 28, 2012.[6]

Career

Darnell’s early research was concentrated on paraneoplastic syndromes (PNDs, the Paraneoplastic Neurologic Disorders), disorders touching on various clinical and basic aspects of biology including Cancer immunology, Neuroimmunology. He was the first to definitively demonstrate that naturally occurring tumor immunity in humans was caused by antigen-specific cytotoxic (CD8+) T cells, helping to generate the foundation for the field of immuno-oncology.[7] His lab was the first to use PND patient antisera to screen expression cDNA libraries to identify the genes encoding the PND antigens.[8][9] This opened the door to the cloning of the Nova,[10] cdr2 and Elavl (Hu) antigens, and led Darnell to hypothesize, based on the intracellular nature of the antigens, that tumor immunity was mediated not by antibodies but by T cells.[11] His laboratory went on to prove this hypothesis, demonstrating cdr2-specific CD*+ T cells were present in the peripheral blood[12] and cerebrospinal fluid[13] of patients with paraneoplastic cerebellar degeneration associated with tumor immunity to breast or ovarian cancers.

The discovery of that the Nova PND antigen (associated with paraneoplastic opsoclonus-opsoclonus) was the first of a class of neuron-specific RNA-binding proteins led his laboratory to question the nature of RNA regulation in the brain and why it might be co-opted in cancer cells. His laboratory developed the HITS-CLIP technique that is used to map the sites of regulatory interactions between RNA-binding proteins and their target RNA sequences, originally using it to study the Nova proteins[14] and subsequently a large number of other RNA binding proteins that are implicated in brain disease, including FMRP[15] (associated with intellectual disability and autism), RbFox[16] (associated with autism), Mbnl[17] (associated with myotonic dystrophy), Elavl[18] (the Hu PND antigen) and cancer (including RBM47[19] and Argonaute-miRNA interactions,[20] both implicated in breast cancer).

Dr. Darnell received his undergraduate degrees in biology and chemistry in 1979 from Columbia University, and his MD/PhD in Molecular Biology in 1985 from Washington University in St. Louis. He was trained in Internal Medicine at Mount Sinai School of Medicine, and in Neurology at Weill Cornell Medical Center, where he was Chief Resident in 1990 with Dr. Fred Plum. He has worked and published extensively with Jerome B. Posner, one of the founders of the study of PNDs, co-authoring a definitive text on the subject.[21] In 2010 he was elected to the Institute of Medicine of the National Academy of Sciences, and a Fellow of the AAAS (the American Association for the Advancement of Science), and in 2014 was elected to the National Academy of Sciences.

Personal life

Dr. Darnell comes from a family of scientists; he is the son of American scientist James E. Darnell, another pioneer in RNA research, the father of Alicia Darnell, second place winner in the 2007 Siemens Competition in Math, Science & Technology,[22] as well as the father to Andrew J. Darnell, MBA, who studies Bioethics and Science Policy at Duke, Paul M. Darnell, undergraduate philosophy student at the University of Maryland, College Park, and is married to Jennifer Darnell, a leading authority on the Fragile X syndrome.[23]
