title: A worm rich in protein: Quantitative, differential, and global proteomics in Caenorhabditis elegans.
abstract: The nematode Caenorhabditis elegans (C. elegans) has been used with much success to study a number of biological processes. Although mostly known for its powerful forward and reverse genetics, work from many different groups over the past years has allowed this model organism to develop into a respectable system for proteomics studies as well. Large-scale survey studies led to improved genome annotation and to the generation of proteome catalogs, which set the stage for subsequent targeted proteomics studies. A number of focused comparative studies contributed to a better understanding of insulin signaling, spermatogenesis, oogenesis, and differential gene expression during development. In addition, C. elegans subproteomes and posttranslational modifications like glycosylation and phosphorylation have been identified. Here we describe the history of C. elegans proteomics, and provide a survey of the different methods that have been applied for relative and absolute quantification in comparative and global protein profiling studies in the worm. These studies suggest that C. elegans will provide a rich trove for "worm proteomicists".
