Heat map diagram showing the relative level of expression of GCAs identified according to "Absolute call" and signal intensity. Thirteen GCAs are known to be recognized by T cells (top panel). White indicates the highest level of expression, and black the lowest. The figure was generated using matrix2png (48); signal intensity values were normalized to a mean of 0 and a variance of 1. MSP, clear cell sarcoma/MSP; RCL, round cell liposarcoma; Fibro, fibrosarcoma; GIST, gastrointestinal stromal tumor; Leio, leiomyosarcoma; D. lipo, dedifferentiated liposarcoma; P. lipo, pleomorphic liposarcoma; MFH, malignant fibrous histiocytoma; mel, melanoma cell lines; s3a, MSP cell line. Mapping to chromosome X was annotated according to the NetAffx™ database (49) and the Human Gene Nomenclature Database (50).
