Our analysis of FADS2 gene expression in colorectal tumor versus normal tissue indicate that FADS2 is upregulated in colorectal tumors compared to normal tissue (p = 5.21 × 10−7) (Additional file 4: Figure S2), supporting the observation that disruption of FADS2 expression may also have an important role in CRC. This evidence concerns the gene FADS2 and colorectal carcinoma.
