It is common knowledge that colorectal cancer (CRC) is one of the major causes of cancer deaths in the developed countries.
Accumulated evidences indicate that lipid metabolism, especially the one in the arachidonic acid (AA)-pathway, appears to play a critical role in the development of CRC. The peroxisome proliferator-activated receptor-γ(PPAR-γ) gene, one of the most important components of the AA-pathway, has been verified to express in a variety of tumor cells. Many studies have been performed about the association between the polymorphism 34 C>G of PPAR-γgene and CRC, but got conflicting results.
AdvertisementA research article to be published on May 7, 2010 in the World Journal of Gastroenterology addresses this question. A research team led by Professor Li-Cheng Dai, confirmed the former data of the association between PPAR-γgene 34 C>G and CRC in the meta-analysis.
In this report, the association between PPAR-γ gene polymorphism 34 C>G and colon cancer risk was observed, and the G allele decreased the colon cancer risk, which is meaningful to early diagnosis, prevention and individual-based treatment of colon cancer. Furthermore, 34 C>G of PPAR-γ gene might be a potential therapeutic target for colon cancer.
