| Research Abstract |
To identify the molecules associated with graft-versus-myeloma (GVM) effect, we screened phage cDNA library of myeloma cell line, RPMI8226 by SEREX immuno-screening. The sera used for the screening was the patient's sera 1 year post allogeneic non-myeloablative stem cell transplantation who obtained complete remission by GVM effect after transplantation. Twenty-eight clones were obtained and after in vivo excision, DNA sequence was performed. Nine genes were identified and among them, TNF-α receptor associated protein 1 (TRAP1) gene had 15 clones and RRS-1 gene had 5 clones. Five genes were unknown genes. The expression of TRAP 1 and RRS-1 were higher in various myeloma cell lines than in myeloid leukemia cell lines. These molecules were potential candidate for immuno-targeting therapy for multiple myeloma.
