Comparisons of expression trends of proteins identified by dMS and SC. (a). Up-regulated (1-red), unchanged (0-black), down-regulated (-1-green). (b-c) Proteins showing the same trend in dMS and SC (strong-match), contradicting trends (no-match) and "weak-match" for proteins identified by one of the methods as not changing. D-down-regulated, N-no change, U-up-regulated. Strong expression "match", (U/U, D/D, N/N according to dMS/SC) (white columns); "weak-match", (N/U, U/N, D/N, N/D by dMS/SC) (grey columns); "no-match", (D/U, U/D) (black columns); (b) Stage II vs. early Stage II (c) Stage III vs. Stage II. (d) Proteins identified by dMS and SC that have the same expression trend ("match", white), contradicting expression trend ("no-match", black) and proteins up-regulated or down-regulated in one method but unchanged in the other ("weak-match", grey).
