Rational Approach to Targeting Transcription Factors with Small Molecule Degraders


2019 Emerging Leader Award

Eric S. Fischer, PhD, Dana-Farber Cancer Institute

Dr. Fischer is exploring a new approach to targeting “undruggable” cancer driver proteins by inducing their complete elimination from tumor cells. This approach will be applied to transcription factors, a class of proteins that control gene expression and help determine the characteristics and behavior of the cell. Because transcription factors are often mutated or mis-expressed in cancer but are difficult to manipulate with existing drugs, Dr. Fischer and his team are devising new drugs that trick a cancer cell into degrading these mutant proteins using the cell’s natural protein degradation pathway. Dr. Fischer, who earned a PhD from the Friedrich Miescher Institute in Switzerland, is Assistant Professor of Biological Chemistry and Molecular Pharmacology at Harvard Medical School and Dana-Farber Cancer Institute. Recently, he was appointed to co-lead a new Center for Protein Degradation at the Dana-Farber Cancer Institute.
