To determine whether increased PPARγ expression and DNA binding activity was correlated with the increased expression of PPARγ target genes in CRC cells, the expressions of FABP2 (fatty acid binding protein 2) and PLIN2 (perilipin 2 or adipophilin), two PPARγ target genes [41,42], were evaluated by real time RT-PCR. This evidence concerns the gene FABP2 and colorectal carcinoma.
