The effect of alpha-tocopheryl hemisuccinate (TS) on lipopolysaccharide (LPS)/interferon-gamma (IFN)-induced nitric oxide production in rat vascular smooth muscle cells (VSMC) was examined. The LPS/IFN-induced NO production was enhanced by TS but not by the other alpha-tocopherol (alpha-T) derivatives alpha-tocopheryl acetate (TA) and alpha-tocopheryl nicotinate (TN), or alpha-T itself. alpha-T, TA and TN inhibited the enhancement by TS of LPS/IFN-induced NO production. The enhancing effect of TS was observed in the presence of LPS, but not IFN, suggesting that TS participates in the LPS-stimulated signal pathway leading to NO production. Protein kinase C (PKC) inhibitors, but not protein kinase A inhibitors, inhibited the enhancing effect of TS on LPS/IFN-induced NO production. Furthermore, TS enhanced the amount of PKCalpha in VSMC. From these results, we concluded that the enhancing effect of LPS/IFN-induced NO production was caused by upregulation of PKC in VSMC.
