A reagent resource to identify proteins and peptides of interest for the cancer community: a workshop report.

On the basis of discussions with representatives from all sectors of the cancer research community, the National Cancer Institute (NCI) recognizes the immense opportunities to apply proteomics technologies to further cancer research. Validated and well characterized affinity capture reagents (e.g. antibodies, aptamers, and affibodies) will play a key role in proteomics research platforms for the prevention, early detection, treatment, and monitoring of cancer. To discuss ways to develop new resources and optimize current opportunities in this area, the NCI convened the "Proteomic Technologies Reagents Resource Workshop" in Chicago, IL on December 12-13, 2005. The workshop brought together leading scientists in proteomics research to discuss model systems for evaluating and delivering resources for reagents to support MS and affinity capture platforms. Speakers discussed issues and identified action items related to an overall vision for and proposed models for a shared proteomics reagents resource, applications of affinity capture methods in cancer research, quality control and validation of affinity capture reagents, considerations for target selection, and construction of a reagents database. The meeting also featured presentations and discussion from leading private sector investigators on state-of-the-art technologies and capabilities to meet the user community's needs. This workshop was developed as a component of the NCI's Clinical Proteomics Technologies Initiative for Cancer, a coordinated initiative that includes the establishment of reagent resources for the scientific community. This workshop report explores various approaches to develop a framework that will most effectively fulfill the needs of the NCI and the cancer research community.

Technical assessment of the first 20 years of research using mouse embryonic stem cell lines.

This review assesses the effect that mouse embryonic stem (ES) cells have had on biomedical research during the 20 years that followed their isolation in 1981. Notable scientific discoveries enabled by these cell lines--including insights into cell cycle regulation, spatial and temporal relationships during development, and the roles of transcription factors and homeobox genes in developmental pathways--are discussed. The acceleration of basic discovery of gene function and the genetic basis of disease using a breakthrough technology (homologous recombination between modified gene constructs and the ES cell genome) became the principal enabling method to establish transgenic laboratory animals with single targeted genetic change. This review also examines the widespread influence of mouse ES cells as an enabling technology by highlighting their effect on drug development paradigms, directed differentiation to treat specific diseases, nuclear transfer protocols used in cloning, and establishment of methodologies for isolating non-rodent ES cells. This review concludes with a brief analysis of the most influential mouse ES cell lines of the first 20 years as viewed within the twin contexts of human disease application and contributions to the primary literature.
