Dr. Agar has recently set up a new laboratory at BWH, oriented towards the validation and implementation of spectroscopic applications to serve surgical and clinical needs in cancer patient care. The interdisciplinary laboratory structure is innovative in itself as it is the fruit of a concerted effort between the Departments of Neurosurgery, Radiology, and Pathology at BWH to create an environment capitalizing on cross-discipline approaches to expedite progress in personalized medicine.
The laboratory will soon harbor high-end mass spectrometers, as well as an NMR magnet dedicated to clinical magnetic resonance spectroscopy (MRS), and a specialized microscope scanner to allow telepathology and validation of spectroscopic approaches to the gold standard of histopathology. Dr. Biochemical factors responsible for tumor development, maintenance, and progression vary from one cancer to another, as well as from one patient to another.
Protein Profiling in Brain Tumors Using Mass Spectrometry. Feasibility of a New Technique for the Analysis of Protein Expression + Author Affiliations Abstract Purpose: The purpose of this research was to perform a preliminary assessment of protein patterns in primary brain tumors using a direct-tissue mass spectrometric technique to profile and map biomolecules. Experimental Design: We examined 20 prospectively collected, snap-frozen normal brain and brain tumor specimens using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS), and compared peptide and protein expression in primary brain tumor and nontumor brain tissues. Results: MS can be used to identify protein expression patterns in human brain tissue and tumor specimens.
Conclusions: We describe a novel tool for the analysis of protein expression patterns in human glial neoplasms. Processing and Preparation of Tumor and Normal Samples.
