The purpose of the present studies was to deter- mine if cranberry extracts (CEs) contain phytochemicals that exert anti- Correspondence inflammatory effects. The human monocytic cell line THP-1 was treated with Jack Vanden Heuvel, Penn State University, two CEs (CE and 90MX) and subsequently challenged with Lipopolysaccharides 325 Life Sciences Building, University Park, (LPS). Tumor necrosis factor (TNF ) expression was decreased in the Pennsylvania 16802. α α Tel: (814) 863-8532; Fax: (814) 863-1696; CE-treated cells, indicative of an anti-inflammatory effect.

In addition, in the CE-treated cells, metallothionein 1F and other metal-responsive genes were induced.
