Additionally, the hTERT540–548 peptide was not detected by mass spectrometry analysis of peptides that were directly isolated from the HLA-A*02:01 molecules of several hTERT-positive tumor cell lines, and proteasome processing experiments conducted in vitro did not result in the production of the hTERT540–548 peptide (unpublished data). This evidence concerns the gene HLA-A and neoplasm.
