Prior Knowledge for Discovery Proteomics Data Interpretation
نویسنده
چکیده
Discovery proteomics usually refers to the search for potential biomarkers of disease from clinical samples such as blood serum, plasma, urine or cerebrospinal fluid (CSF). These samples are typically analyzed using high-throughput Mass Spectral (MS) technologies yielding highdimensional data that needs interpretation in order to identify a small number of protein/peptide biomarkers predictive of disease states. This research provides an analysis of a discovery process leading to identification of potential biomarkers of a neurodegenerative disease called Amyotrophic Lateral Sclerosis (ALS). Task-specific domain knowledge is identified that can be used as priors to guide the search. Ongoing research involves the identification of such prior knowledge, and its use within rule learning and probabilistic machine learning systems to enhance the accuracy of biomarker panels predictive of disease states.

Proteomics enables understanding the composition, structure, function and interactions of the entire protein complement of a cell, a tissue, or an organism under exactly defined conditions. Some factors such as stress or drug effects will change the protein pattern and cause the present or absence of a protein or gradual variation in abundances. Changes in the proteome provide a snapshot of the...
