We report here the identification of a new shared human melanoma antigen recognized by a human leukocyte antigen (HLA)-A*68011-restricted cytotoxic T lymphocyte clone (CTL 128). The cDNA encoding this antigen is composed of a partially spliced form of the melanocyte differentiation antigen tyrosinase-related protein (TRP)-2, containing exons 1-4 with(More)
The RanGTPase activating protein RanGAP1 has essential functions in both nucleocytoplasmic transport and mitosis. In interphase, a significant fraction of vertebrate SUMO1-modified RanGAP1 forms a stable complex with the nucleoporin RanBP2/Nup358 at nuclear pore complexes. RanBP2 not only acts in the RanGTPase cycle but also is a SUMO1 E3 ligase. Here, we(More)
Neointima formation, the leading cause of restenosis after catheter angioplasty, is a paradigm for vascular proliferative responses. Neointima formation is self-limiting after a variable degree of tissue growth, causing significant renarrowing in a substantial number of patients. To investigate the mechanisms that limit neointima formation we studied the(More)
Human melanomas can express unique tumor antigens, resulting from mutated proteins, and shared epitopes encoded for by normal genes, but these two classes of antigens have not been previously compared for immunogenicity and retention in metastatic cells. Here, we identified a new unique antigen generated by a point mutation in the peroxiredoxin 5 (Prdx5)(More)
To assess whether RAS oncogenes may affect the expression of cytokines in tumor cells, the presence of interleukins (IL) 1 alpha, 1 beta, 4, 6, 7, and 8, tumor necrosis factor (TNF) alpha and interferon gamma mRNA has been analyzed by reverse transcriptase-polymerase chain reaction in 19 melanoma clones derived from the metastatic cell line 665/2 and(More)
