a Spot numbers refer to those in Figure S1.

b Accession numbers of proteins were derived from the Swiss-Prot database.

c The normalized abundance was calculated by dividing the average spot intensity of a Cy3 or Cy5 labelled sample by the average spot intensity of the Cy2 labelled internal standard.

d Fold-difference (FD) was calculated by dividing the normalized abundance of a protein in the poor prognosis group by that for good prognosis.

e p-values were calculating using 1-Way ANOVA.

PP, poor prognosis; GP, good prognosis. Calreticulin (bold) was verified by SRM.
