Correlation between protein expression levels and tumor size.

<p>Protein expression levels of the 26 proteins that overlapped in the t-test and OPLS analyses correlate with the size of the tumors. Two proteins have increased expression levels (light grey dots/lines), the rest have decreased expression levels (black dots/lines). Corresponding protein names can be found in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087951#pone.0087951.s005" target="_blank">Table S4</a>.
