Fig. 4. IL-6 production in endothelial cells during zinc deficiency and supplementation and after exposure to linoleic acid (FA) or TNF. Cells were culture for 8 days in media supplemented with only 1% FBS and subsequently enriched either with zinc (10 µM) for 48 hours and/or treated with FA or TNF for 12 hours. Values are mean±SEM (n=6). *Significantly different from respective cultures without added zinc.
