本研究的目的是确定细胞因子是否调节单核吞噬细胞中白三烯C4(LTC 4)合酶的表达。在THP-1细胞中调查一组细胞因子的LTC 4合酶mRNA的变化。TGF-β 1、-2和-3具有显著的刺激作用。TGF-β的加入导致LTC 4合酶mRNA在6 h时呈时间依赖性增加,并持续至48 h。此外,这种调节导致在7天的LTC 4合成酶的免疫反应性蛋白质的增加。细胞的TGF-β调节导致刺激的LTC 4合酶活性的时间和剂量依赖性增加。用含有1.2 kb LTC 4合酶启动子的启动子-报告基因构建体瞬时转染THP-1细胞后,TGF-β处理导致报告基因活性增加2倍。通过放线菌素D处理的细胞中的RNA酶保护试验评估,TGF-β调节并没有延长LTC 4合酶mRNA的半衰期。放线菌酮暴露实验表明,新的蛋白质合成是不需要观察到的刺激作用的TGF-β对LTC 4合酶mRNA。我们的结论是LTC 4合成酶的表达增加在转录水平的TGF-β在单核吞噬细胞。
The goal of this study was to determine whether cytokines modulate leukotriene C4 (LTC4) synthase expression in mononuclear phagocytes. A panel of cytokines was surveyed for changes in LTC4 synthase mRNA in THP-1 cells. TGF-beta1, -2, and -3 had significant stimulatory effects. The addition of TGF-beta resulted in a time-dependent increase in LTC4 synthase mRNA at 6 h, which persisted through 48 h. Furthermore, this conditioning resulted in an increase in immunoreactive protein for LTC4 synthase through 7 days. TGF-beta conditioning of cells resulted in a time- and dose-dependent increase in stimulated LTC4 synthase activity. Following transient transfection of THP-1 cells with a promoter-reporter construct containing 1.2 kb of the LTC4 synthase promoter, TGF-beta treatment resulted in a 2-fold increase in reporter activity. Conditioning with TGF-beta did not prolong the half-life of LTC4 synthase mRNA, as assessed by RNase protection assays in actinomycin D-treated cells. Cycloheximide exposure experiments revealed that new protein synthesis was not required for the observed stimulatory effect of TGF-beta on LTC4 synthase mRNA. We conclude that LTC4 synthase expression is increased at a transcriptional level by TGF-beta in mononuclear phagocytes.
