    Abstract:
    Adenoid cystic carcinoma (ACC) is an uncommon salivary gland malignancy characterized by indolent yet relentless growth that exhibits inherent resistance to systemic chemotherapy, surgical salvage and conventional radiotherapy. We used microarray analysis to characterize gene expression changes associated with ACC. Eight ACC patient specimens were compared with normal parotid gland tissue and the ACC3 cell line. Differentially expressed genes were identified (512 total) using supervised analysis methods and functional categories assigned using OntoExpress. Genes associated with morphogenesis, neurogenesis, proliferation and apoptosis characterized ACC tumors. Genes associated with saliva production and immune response characterized normal parotid tissues while the ACC3 cell line expressed genes primarily associated with proliferation, chromosome maintenance and the cell cycle. These results demonstrate that ACC tumors express genes associated with early developmental processes including morphogenesis and neurogenesis implicating oncogenic events that result in dedifferentiation of normal salivary glands.
