本研究以LS174T细胞为模型,探讨淫羊藿苷和磷酸化淫羊藿苷对lps诱导的杯状细胞功能障碍的保护作用。我们的研究结果表明,淫羊藿苷和磷酸化淫羊藿苷提高了lps处理的LS174T细胞的活力,降低了乳酸脱氢酶的活性。淫羊藿苷和磷酸化淫羊藿苷减弱了lps诱导的粘蛋白2合成和分泌的变化。此外,淫羊藿苷和磷酸化淫羊藿苷降低了lps处理的LS174T细胞的ROS、MDA和H2O2水平,提高了SOD、GPx、CAT和T-AOC的活性。此外,淫羊藿苷和磷酸化淫羊藿苷组IL-1β、IL-6、IL-8和TNF-α水平降低。此外,淫羊藿苷和磷酸化淫羊藿苷降低了lps处理的LS174T细胞中Bip、XBP1、GRP78、CHOP、caspase-3和caspase-4的基因丰度或酶活性。我们的数据表明,淫羊藿苷和磷酸化淫羊藿苷通过调节氧化应激、炎症、凋亡和粘蛋白的表达,有效地减轻了lps诱导的肠杯状细胞功能损伤。
In this study, we used LS174T cells as a model to investigate the protective effects of icariin and phosphorylated icariin on LPS-induced goblet cell dysfunction. Our results indicated that icariin and phosphorylated icariin increased the cell viability and decreased lactate dehydrogenase activity in LPS-treated LS174T cells. Icariin and phosphorylated icariin attenuated LPS-induced changes in mucin 2 synthesis and secretion. Besides, Icariin and phosphorylated icariin reduced the levels of ROS, MDA, and H2O2 and increased the activity of SOD, GPx, CAT, and T-AOC in LPS-treated LS174T cells. Moreover, the levels of IL-1β, IL-6, IL-8, and TNF-α were reduced in the Icariin and phosphorylated icariin group. Furthermore, Icariin and phosphorylated icariin decreased gene abundance or enzyme activity of Bip, XBP1, GRP78, CHOP, caspase-3, and caspase-4 in LPS-treated LS174T cells. Our data suggest that Icariin and phosphorylated icariin effectively attenuate LPS-induced intestinal goblet cell function damage through regulating oxidative stress, inflammation, apoptosis, and mucin expression.
