HLA-A2-Restricted Epitopes Identified from MTA1 Could Elicit Antigen-Specific Cytotoxic T Lymphocyte Response.

ABSTRACT: Overexpression of metastasis-associated protein 1 (MTA1) has been observed in many human malignancies and is significantly related to tumor invasion and metastasis, therapeutic resistance to radiation and chemotherapy, making MTA1 an ideal candidate tumor antigen. We identified several human leukocyte antigen- (HLA-) A2-restricted epitopes in MTA1 and evaluated their binding ability to HLA-A^∗0201 molecules. Subsequently, a recombinant fragment encompassing the dominant epitopes, MTA1_(1-283), was expressed, and the abilities of the selected epitopes of MTA1 and the MTA1_(1-283) fragment to induce cytotoxic T lymphocytes (CTLs) were examined. Our results indicated that the epitopes and MTA1_(1-283) fragment elicited HLA-A2-restricted and antigen-spec
