Pathway analysis of BaP exposed features from human serum with different
levels of BaP. A total of (5/119) enriched pathways were determined (Filled gray
bars indicate significance less than P < 0.05, and the
cutoff is indicated by the dotted line). These pathways include arachidonic acid
regulation (13/39), leukotriene regulation (15/52), C21-steroid hormone
regulation (7/21), histidine metabolism (3/7), and glycerophospholipid
biosynthesis (8/36). Numbers in the parentheses indicate the overlap of the
metabolites as matched through KEGG and the Edinburgh human metabolic network
databases matching using m/z and RT.
