The putative cancer preventive agent 3,3'-diindolylmethane (DIM) is formed in the acidic environment of the stomach following consumption of indole-3-carbinol (I3C), which is present in vegetables of the Brassica genus. We have recently shown that the transcription factor Sp1 is involved in the regulation of both proliferation and de novo lipogenesis in cancer cells. Here we show that DIM inhibits the proliferation of 3 human breast cancer cell lines, MCF-7, MDA-MB-231, and SKBr-3, and concomitantly inhibits the expression of Sp1 and fatty acid synthase (FAS). There were no DIM-related effects on the proliferation or expression of Sp1 or FAS in the nontumorigenic human breast epithelial cell line MCF-10A. These results suggest that inhibition of Sp1 and/or FAS expression could contribute to the anticancer properties of the dietary indoles.
