Notes. Markers that exhibited statistical significance through the Kolmogorov-Smirnov test when pre-exposure vs. 6 h post-exposure data were compared. Pathways affected include energy metabolism with implications for fatty acid oxidation, and purine catabolism potentially affecting the purine salvage pathway.
