Differentially expressed proteins in different T stages.

<p>a) The hexagonal array displays the changing patterns of the proteins expression from Ta to T4. Each hexagon represents a protein, the color of a hexagon reflects its level of expression in current T stage with respect to corresponding non-tumor tissue. b) The significantly expressed proteins between tumor and non-tumor tissues in different T stages were listed in their own circle which represents a specific stage. The proteins listed in the overlap area were shared by 2 adjacent stages. Proteins in red are upregulated and proteins in green are downregulated.
