FABP1 and PPARγ expression in The Cancer Genome Atlas HiSeq colorectal carcinoma data was distributed across the pre-assigned classification of colorectal carcinoma subtypes according to Guinney et al.4 FABP1 and PPARγ show decreased expression in the microsatellite instability immune subgroup (CMS1) when compared with the other categories. FABP1, fatty acid-binding protein 1; PPARγ, proliferator-activated receptor γ; UNK, unknown subtype.
