Table II. Up-regulated proteins, identified in group 2. Gene and protein names are truncated from the UniProtKB IDs to the first highlighted entry for each. SigP, number of iTRAQ ratios significantly different from 1, out of a possible 12 samples. Median ITRAQ, median unadjusted iTRAQ value across all of the samples for that protein comparing MM cell lines to a non-malignant mesothelial cell secretome.
