This figure represents the percentage of expressed proteins according to their cellular function.

This figure demonstrates the differences in salivary protein profiles between HER2/neu -positive and HER2/neu -negative samples. Please change.

This figure illustrates the protein profiles for HER2/neu-receptor-positive and HER2/neu-receptor-negative samples. As shown in the far right red and green dyed gel comparisons, there are numerous differences between the two profiles.

The figure represents the natural logarithm differential expression of salivary proteins. To the right and left of the figure listed in rank order of expression are the up- and downregulated proteins, respectively.

It illustrates the presence of profilin-1 in the SKBR3 and HSG cell lysates and saliva sampled from healthy, benign, and malignant tumor patients. Profilin is a downregulated protein in the presence of malignancy, and it is visualized by the lighter bands associated with malignancy. It is also worth noting that the Her2/neu-receptor-negative band is darker than the Her2/neu-receptor-positive counterpart suggesting further downregulation of the profiling-1 protein.
