Mass Spectrometry Data Analysis for Early Detection of Inherited Breast Cancer
Mass Spectrometry (MS) can be used as a detector in High Performance Liquid Chromatography (HPLC) systems or as a tool for direct protein/peptides profiling from biological samples. Data Mining (DM) is the semi-automated extraction of patterns representing knowledge implicitly stored in large databases. The combined use of MS with DM is a novel approach in proteomic pattern analysis and is emerging as an effective method for the early diagnosis of diseases. We describe the workflow of a proteomic experiment for early detection of cancer which combines MS and DM, giving details of sample treatment and preparation, MS data generation, MS data preprocessing, data clustering and classification.
