Abstract

Dietary fatty acid patterns have been linked to the prevalence of certain cancers, however in oral carcinoma is limited. Thus, we investigated the chemopreventive effects of various dietary n-6 and n-3 fatty acids in a 9,10-dimethyl-1,2-benz[. a]-anthracene (DMBA)- and betel quid extract (BQE) -induced hamster oral cancer model. Thirty 6-week-old adult male hamsters were housed and divided into normal, low, and high dietary n-6 and n-3 fatty acid groups under DMBA + BQE treatment for 16 weeks. The right buccal pouch of all hamsters were evaluated by tumor number, volume, burden and selected inflammatory parameters. The results indicate that the low dietary n-6/n-3 fatty acid group exhibited a significantly lower tumor number, volume, and burden than those of the other groups. Furthermore, this group had significantly lower nuclear factor-κB, proliferating cell nuclear antigen, and cyclin D1 expression in the right buccal pouch tissue. In conclusion, the lower dietary n-6/n-3 fatty acid ratio exerted chemopreventive effects in the DMBA- and BQE-induced hamster oral cancer model.
