Ovarian cancer (OC) is the leading cause of death among gynecological malignancies and represents the fifth leading cause of cancer-related death in women.

To support current research endeavors in OC, we have developed an integrated knowledge database called Dragon Database for Exploration of Ovarian Cancer Genes (DDOC). DDOC provides a comprehensive compilation of the published research related to the genes associated with OC.

Many aspects of the information provided in the DDOC were curated by biologists, which emphasize its accuracy. DDOC provides details of the cell line, tissue or cell type, expression status, disease stage, tumour grade, OC type and laboratory method provided in the literature. The links to the relevant sources of data used to extract information related to genes are also included.

DDOC is freely accessible for academic and non-profit users.
