Compared with those individuals with the CC allele, increasing risk of CRC with increasing red meat intake was more pronounced among individuals with T alleles of PPARγC161T (rs3856806), but the association was not significant.
The stratified analysis revealed that the <i>PPARG</i> r</span>s3856806 C>T polymorphism also increased the risk of CRC, especially in male, ≥61 years old, never smoking, never drinking, BMI ≥ 24 kg/m<sup>2</sup>, colon cancer and rectum cancer subgroups.
Several studies evaluated the association between peroxisome proliferators-activated receptor gamma (PPARγ) Pro12Ala (rs1801282), and His477His (rs3856806) polymorphisms and the risk of colorectal cancer (CRC).However, the results were not stable.
