Hanno Steen

Principal Investigator

Dr. Hanno Steen, PhD, is an Associate Professor of Pathology at Harvard Medical School, whose laboratory is located at Boston Children’s Hospital. Dr. Steen’s group research has three focal areas: i) The discovery of urinary biomarkers for diagnostic purposes in a wide range of acute and chronic diseases including appendicitis, Kawasaki disease, TB, traumatic brain injury, and Crohn’s Diseases. To this end the Steen Lab has developed a urine proteomics platform which allows for the fast and efficient processing and proteomic analysis of urine specimens. ii) Use of proteomics to study post-translational mechanisms of protein regulation, with particular emphasis on protein degradation in mitosis and development. The Steen group developed the concept of co-regulation proteomics algorithms that correlates protein abundance traces specific enzyme activities and functions. This work resulted in the identification of kinens, as a new class of cell cycle dependent substrates of the Anaphase Promoting Complex. iii) Method development to improve a) processing of proteomic samples, b) accuracy and precision of protein quantification and iii) computational methods for the qualitative and quantitative analysis of proteomic data. For instance, the FLEXIQuant approach developed by the Steen Lab, which allows for the exquisitely detailed characterization of selected proteins and their post-translational modification, has been instrumental for studying multikinase mechanisms (Nat Methods. 2012;9:504), and the post-translational regulation of Tiki1 in Xenopus development (Cell. 2012;149:1565) and kinesin C1 during mitosis (EMBO J. 2014;33:385).

Judith Steen

Principal Investigator

Dr. Judith Steen is an Associate Professor of Neurobiology at Harvard Medical School, a member of the Harvard Stem Cell Institute and the Director of the Neuroproteomics Laboratory in the F. M. Kirby Neuroscience Center at Boston Children’s Hospital. Her laboratory works to understand neuro-regeneration and neurodegenerative diseases using systems biology approaches. The laboratory develops novel qualitative and quantitative methodologies at the interface of proteomics and transcriptomics with special emphasis on computational proteomics approaches. These novel quantitative methods and bioinformatics tools developed by the Steen Laboratory are being applied to understand the biology of regeneration and neurodegeneration in both mouse models, stem cells and human tissues, to find molecular targets for therapeutics, and to identify biomarkers of the neurodegenerative process. Further functional studies using biochemical, molecular and cell biology approaches are used to verify and understand the role of the targets and biomarkers in the context of injury and disease. The goal of this research is to use molecular information provided by our quantitative proteomics measurements in order to ameliorate neurodegeneration and promote regeneration.
