1 7-Ketocholesterol upregulates interleukin-6 via mechanisms that are distinct from those of tumor necrosis factor-alpha, in vascular smooth muscle cells. 7-ketocholesterol interleukin 6 Homo sapiens
2 This study investigated the effects of 7-ketocholesterol on interleukin (IL)-6 expression in vascular smooth muscle cells (VSMC). 7-ketocholesterol interleukin 6 Homo sapiens
3 Among the 7 IL examined, only IL-6 transcript was increased by 7-ketocholesterol treatment in human aorta smooth muscle cells. 7-ketocholesterol interleukin 6 Homo sapiens
4 IL-6 transcripts increased up to 24 h after treatment with 7-ketocholesterol, and this effect was profoundly repressed by treatment with p38 MAPK inhibitors and to a lesser extent JNK inhibitors. 7-ketocholesterol interleukin 6 Homo sapiens
5 Mechanisms of IL-6 induction by 7-ketocholesterol were investigated in comparison with tumor necrosis factor (TNF)-alpha. 7-ketocholesterol interleukin 6 Homo sapiens
6 7-ketocholesterol significantly increased the amount of intracellular IL-6 protein in the presence of brefeldin A. 7-ketocholesterol interleukin 6 Homo sapiens
7 7-Ketocholesterol also enhanced IL-6 release from VSMC. 7-ketocholesterol interleukin 6 Homo sapiens
8 IL-6 release by 7-ketocholesterol, although significant, was not as remarkable as that induced by TNF-alpha. 7-ketocholesterol interleukin 6 Homo sapiens
9 These data suggest that 7-ketocholesterol upregulates IL-6 via mechanisms distinct from TNF-alpha and contributes to the intra- and extracellular IL-6 deposits within the vasculature. 7-ketocholesterol interleukin 6 Homo sapiens
10 These data suggest that 7-ketocholesterol upregulates IL-6 via mechanisms distinct from TNF-alpha and contributes to the intra- and extracellular IL-6 deposits within the vasculature. 7-ketocholesterol interleukin 6 Homo sapiens
