Abstract
Peroxisome proliferator-activated receptor γ (PPARγ) has been linked with possible antineoplastic effects in colorectal carcinogenesis. However, data for the possible link between PPARγ and breast cancer risk are sparse. We assessed the association of three polymorphisms in PPARγ (rs10865710 [C-681T], rs1805192 [Pro12Ala], and rs3856806 [C1431T]) with the risk of breast cancer in an ethnic Chinese female population in Taiwan. In addition, interactions with estrogen exposures were also explored. Genotypes for the PPARγ polymorphisms were determined on 291 incident breast cancer cases and 589 matched controls by fluorogenic 5′-nuclease assay. The at-risk haplotypes were defined according to the three polymorphisms in the following order: C-681T, Pro12Ala, and C1431T, which include CCT, GGT, and GGC. In addition, a critical period of estrogen exposure was estimated by the interval between age at menarche and age at first full-term pregnancy. Overall, there was no evidence of a significant impact of individual polymorphisms of PPARγ on breast cancer risk. However, the haplotype analysis revealed that women harboring at-risk haplotypes showed a significant 67% increase in breast cancer risk [adjusted odds ratio (OR) 1.67; 95% confidence interval (CI) 1.11–2.52]. Furthermore, there was a significant joint effect of estrogen exposure-related factors and at-risk haplotypes of PPARγ on breast cancer risk (adjusted OR 4.04; 95% CI 1.89–8.65), particularly in premenopausal women. The present study implicates a role for PPARγ in breast cancer risk. Mechanistic studies to fully elucidate the mechanisms underlying PPARγ’s effects should be pursued in future investigations.
