Research in the Van de Rijn and West Lab focuses on gene microarray analysis of human soft tissue tumors (sarcomas). In addition they work with tissue microarrays to characterize large numbers of novel antisera raised against peptides derived from genes found to be of interest during gene array analysis. These genes are not only identified in sarcomas but, through collaborations with other laboratories, also in a large number of other human neoplasms, including breast, kidney, prostate, lung, and liver tumors.
