Antioxidants inhibit cytokine production and suppress NF-kappaB activation in CAPAN-1 and CAPAN-2 cell lines.

Interleukin (IL) -6 and IL-8 are cytokines that have been shown to play a role in several pancreatic diseases, including acute pancreatitis, chronic pancreatitis, and pancreatic adenocarcinoma. Previously, we have demonstrated that tumor necrosis factor-alpha (TNF-alpha) and gram-negative bacterial lipopolysaccharide stimulate production of IL-6 and IL-8 and activation of the transcription factor NF-kappaB in the well-differentiated pancreatic ductal adenocarcinoma cell lines CAPAN-1 and CAPAN-2. In these studies we have examined the effect of chain-breaking and glutathione-enhancing antioxidants on NF-kappaB activation and production of IL-6 and IL-8 in these cell lines. Generally, suppression of NF-kappaB activation correlated well with inhibition of IL-6 and IL-8 secretion. In the CAPAN-2 cell line, antioxidants inhibited both NF-kappaB activation and IL-6 and IL-8 secretion. In the CAPAN-1 cell line, antioxidants generally failed to suppress both NF-kappaB activation and IL-6 and IL-8 secretion. The single exception was the chain-breaking antioxidant butylated hydroxyanisole (BHA), which markedly inhibited IL-6 and IL-8 secretion, but had no effect on NF-kappaB activation. These findings may have implications for the treatment of acute and chronic pancreatitis and pancreatic cancer.[1]
