Plasma PLA₂ activities were elevated in cancer groups vs. healthy controls.

<p>Comparison of PLA₂ activities in the healthy control (normal colonoscopy; n = 77) and CRC (n = 38) groups. A. Comparison of PLA₂ activities in the healthy (n = 79) and other cancer groups. Lung cancer (LC, n = 95), bladder cancer (BC, n = 31) and pancreatic cancer (PC, n = 38). The distribution of the natural and individual groups of PLA₂ activities were analyzed as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0057081#s2" target="_blank">Materials and Methods</a>. The mean values of PLA₂ activities were presented by the “+” in the figure. <b>*</b><i>P</i><0.05; <b>**</b><i>P</i><0.01; <b>***</b><i>P</i><0.001.
