Abstract
Mass spectrometry and proteomics have witnessed tremendous progress in the past two decades. From instrumentation and novel techniques and methodologies, to advanced software packages that handle large data sets, some of the most complex biological problems can be addressed today by capitalizing on the power of this technology. In our laboratory we develop proteomics approaches for the analysis of breast cancer cells. Our goal is to use a systems-level approach to uncover biological mechanisms that lead to uncontrolled cell proliferation, novel markers indicative of disease and protein clusters that can be used as effective therapeutic targets. In addition, we develop microfluidic instrumentation as a mass spectrometry front-end for high-throughput sample processing. In this presentation we will discuss the challenges that researchers face when dealing with the complexity of biological systems and the unique benefits offered by mass spectrometry in complementing genomics research. In particular, we will focus on the implications of achieving proteome depth, the complex dimension of posttranslational modifications, and proper timing of experimental conditions with biological relevance. Ultimately, we will discuss the potential of technologies such as mass spectrometry to transform our thinking about addressing problems that lie at the root of human disease.
