摘要:

目的 探究芦丁对脂多糖(LPS)诱导的绵羊瘤胃上皮细胞屏障功能、炎症损伤的影响。 方法 体外培养绵羊瘤胃上皮细胞,用不同浓度LPS(0、1、5、10、50、100 μg/mL)刺激建立瘤胃上皮细胞损伤模型,确定LPS的最佳作用浓度和作用时间。以不同浓度芦丁(0、25、50、100、150 μg/mL)对瘤胃上皮细胞进行预处理,采用MTT法检测细胞活力,计算细胞相对增殖率,确定芦丁的适宜作用浓度和作用时间。基于筛选的LPS和芦丁作用浓度和时间进行细胞分组处理,分别为对照组(CON)、LPS组、芦丁组(R)以及芦丁干预组(R+LPS)。利用ELISA试剂盒测定细胞上清液中白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、IL-10含量;通过实时荧光定量PCR检测IL-1β、IL-4、IL-6、IL-8、IL-10、IL-12、TNF-α、γ-干扰素(IFN-γ)、CXC趋化因子配体8(CXCL8)、CXCL9、咬合蛋白(Occludin)、闭锁小带蛋白-1(ZO-1)、闭合蛋白-1(Claudin-1)、Claudin-4的mRNA相对表达量。 结果 通过试验筛选,最终确定1 μg/mL LPS作用9 h作为建立瘤胃上皮细胞损伤模型的最佳作用条件;100 µg/mL芦丁处理8 h作为芦丁在体外对瘤胃上皮细胞预保护的最佳作用条件。与CON组相比,LPS组细胞上清液中IL-1β、TNF-α含量均显著升高(P<0.05),IL-10含量显著降低(P<0.05)。与LPS组相比,R+LPS组细胞上清液中IL-1β、TNF-α含量显著降低(P<0.05),IL-10含量显著升高(P<0.05)。实时荧光定量PCR结果显示,与CON组相比,LPS组瘤胃上皮细胞中IL-1β、IL-6、IL-12、TNF-α、IFN-γ、CXCL8、CXCL9 mRNA表达量显著升高(P<0.05),IL-4、IL-10、Claudin-4、ZO-1 mRNA表达量显著降低(P<0.05)。与LPS组相比,R+LPS组瘤胃上皮细胞中IL-1β、IL-6、IL-12、TNF-α、INF-γ、CXCL8、CXCL9 mRNA表达量显著降低(P<0.05),IL-4、IL-10、ZO-1、Claudin-4 mRNA表达量显著升高(P<0.05)。 结论 本试验条件下,100 µg/mL芦丁作用8 h对LPS诱导的瘤胃上皮细胞屏障功能和炎症损伤具有明显的保护作用。

Abstract:

Objective The purpose of this experiment was to investigate the effects of rutin on the barrier function and inflammatory injury of sheep rumen epithelial cells induced by lipopolysaccharide (LPS). Method Sheep rumen epithelial cells were cultured in vitro. Different concentrations of LPS (0, 1, 5, 10, 50, and 100 μg/mL) were used to stimulate and establish a model of rumen epithelial cell injury. The optimal concentration and duration of LPS action were determined. The rumen epithelial cells were pre-treated with different concentrations of rutin (0, 25, 50, 100, and 150 μg/mL), and the cell viability was detected by MTT assay. The relative proliferation rate of the cells was calculated to determine the appropriate concentration and duration of action of rutin. Based on the selected concentrations and durations of LPS and rutin, the cells were grouped and treated accordingly. They were respectively designated as control group (CON), LPS group, rutin group (R), and rutin intervention group (R+LPS). The contents of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and IL-10 in the cell supernatant were determined by ELISA kit. The relative mRNA expression levels of IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12, TNF-α, IFN-γ, CXCL8, CXCL9, Occludin, ZO-1, Claudin-1, and Claudin-4 were detected by Real-time quantitative PCR. Result Through experimental screening, it was ultimately determined that 1 μg/mL LPS, when applied for 9 hours, was the optimal condition for establishing the rumen epithelial cell injury model. A treatment of 100 µg/mL rutin for 8 hours was identified as the optimal condition for the pre-protective effect of rutin on rumen epithelial cells in vitro. Compared with CON group, the contents of IL-1β and TNF-α in the cell supernatant of LPS group were significantly increased (P<0.05), while IL-10 content was significantly decreased (P<0.05). Compared with LPS group, the contents of IL-1β and TNF-α in the cell supernatant of R+LPS group were significantly decreased (P<0.05), while IL-10 content was significantly increased (P<0.05). The Real-time quantitative PCR results showed that compared with CON group, the mRNA expression levels of IL-1β, IL-6, IL-12, TNF-α, IFN-γ, CXCL8, and CXCL9 in the rumen epithelial cells of LPS group were significantly increased (P<0.05), the mRNA expression levels of IL-4, IL-10, Claudin-4, and ZO-1 were significantly decreased (P<0.05). Compared with LPS group, the mRNA expression levels of IL-1β, IL-6, IL-12, TNF-α, INF-γ, CXCL8, and CXCL9 in the rumen epithelial cells of R+LPS group were significantly decreased (P<0.05), the mRNA expression levels of IL-4, IL-10, ZO-1, and Claudin-4 were significantly increased (P<0.05). Conclusion Under this experimental conditions, 100 µg/mL rutin, when applied for 8 hours, exhibited a significant protective effect on the barrier function and inflammatory injury of the rumen epithelial cells induced by LPS.
