Since the prognosis of human osteosarcoma in advanced stage remains poor, the development of new and effective therapies including immunotherapy is required. To identify tumor-associated antigens of osteosarcoma applicable to the immunotherapy of this malignancy, we employed the serological analysis of recombinant cDNA expression library (SEREX) technique that defines tumor antigens recognized by the humoral immune system. Screening a cDNA library derived from an osteosarcoma cell line MG63 with sera from osteosarcoma patients identified 43 positive clones, representing 14 distinct antigens. Among them, CLUAP1 (clusterin-associated protein 1) was highly expressed in osteosarcoma tissue samples and cell lines. Overexpression of CLUAP1 was observed in other malignancies including ovarian, colon, and lung cancers. Our results suggest that CLUAP1 may be useful as a prognostic/diagnostic marker and/or for a target of immunotherapy of osteosarcoma.
