Figure 1

Expression correlations of synonymous probesets. X axis indicates expression dataset IDs, Y axis shows the Pearson Correlation Coefficient (PCC) of synonymous probesets summarized for each dataset. A) Expression correlations were calculated for the MOE430A_2 array based on 30 expression datasets. Synonymous probesets were compiled at three different levels: gene level, Affy-protein level, and our protein level. B) Expression correlations were calculated for the HG-U133A array based on 28 expression datasets. Synonymous probesets were compiled at four different levels: gene level, Affy-protein level, our protein level, and Harbig-protein level (according to Harbig et al.'s annotation work).
