Abstract
High fat diets promote the development of mammary tumors induced in rats by 7,12-dimethylbenz(a)anthracene (DMBA), and polyunsaturated fats are more effective than saturated fats. This difference is related to the linoleic acid content of polyunsaturated vegetable oils, but the amount of linoleate required for maximum tumor promotion appears to be higher than indicated by earlier experiments. Comparison of the effects of a polyunsaturated vegetable oil (corn oil) containing linoleate with a fish oil (menhaden oil) containing polyunsaturated fatty acids derived from linolenic acid showed that higher dietary levels of corn oil increased the yield of DMBA-induced mammary tumors, while corresponding levels of menhaden oil had an inhibitory effect. This is further evidence that promotion of mammary tumorigenesis by polyunsaturated vegetable oils may be mediated by prostaglandins or other biologically active eicosanoids derived from n-6 fatty acids.

The mechanism underlying inhibition of mammary tumorigenesis may be linked, in part, to the inhibitory effect of both EPA and DHA on arachidonic acid metabolism.

The differences in tumor yield could not be correlated with changes in prostaglandin E concentration in the mammary fat pads of normal animals maintained on similar diets, suggesting that linoleate may act by some other mechanism to stimulate mammary tumorigenesis.

Data suggest that at least part of the stimulatory effect of polyunsaturated fat on 7,12-dimethylbenz(a)anthracene-induced mammary tumorigenesis may be mediated through an increased synthesis of prostaglandins.

The results suggest that the growth-enhancing effect of dietary fat on transplantable mammary tumors may be mediated through the cellular immune system with the possible involvement of prostaglandins in this process.

Results indicated that the rate of tumor growth in untreated rats was significantly greater when the dietary fat content was either 10 or 20% compared to diets containing either 2 or 5% fat; the tumor growth-promoting effects of 10 and 20% fat diets were completely abrogated in rats treated with indomethacin.

A study of tumor incidence and tumor growth rates in 7,12-dimethylbenz(a)anthracene-treated female Sprague-Dawley rats fed different types and amounts of dietary fat indicates that the difference in tumor incidence may be a reflection of marked differences in the growth of neoplastic clones to a palpable size within the time frame of the study.

The growth of mammary tumors was not related to prostaglandin synthesis but was related to the availability of arachidonate, and eicosa-5,8,11,14-tetraynoic acid (TYA) was an effective inhibitor for the conversion of linoleate to arACHidonate.
