Abstract

The aerial part of ​Rubia cordifolia ​L. has been used as an herbal medicine for a long time with various pharmacological activities, including anti-inflammatory, anticancer, and antibacterial activities. The most notable usage of these was that this herbal medicine had good therapeutic effects on diarrhea caused by various factors. However, the mechanism for the ethanolic extract of ​R. cordifolia ​L. (RCEE) to treat Ulcerative colitis (UC) effectively is still unclear. In this study, DSS successfully induced UC mice and then intervene using different polar parts of RCEE. The results indicated that RCEE-treatment inhibited colonic combination NLRP3 inflammasome formation and IL-6/JAK2/STAT3 activation in vivo, significantly ameliorating the clinical symptoms, including alleviating colonic mucosal damage and infiltration of macrophages, suppressing the release of inflammatory cytokines, and reducing mortality. Taken together, this study suggests that dual inhibition of NLRP3 inflammasome and IL-6/JAK2/STAT3 pathways activation using RCEE may be a promising therapeutic strategy for preventing the progression of UC.

LabEx Luminex平台助力探索茜草乙醇提取物有效治疗溃疡性结肠炎的机制

本周为大家带来的文献为发表Heliyon. (IF: 3.4)的” Rubia cordifolia L. ameliorates DSS-induced ulcerative colitis in mice through dual inhibition of NLRP3 inflammasome and IL-6/JAK2/STAT3 pathways”。本文使用了LabEx提供的Luminex检测服务。

 

茜草(Rubia cordifolia L.)的地上部分长期以来被用作草药,具有多种药理活性,包括抗炎、抗癌和抗菌作用。其中最显著的用途是该草药对由各种因素引起的腹泻具有良好的治疗效果。溃疡性结肠炎(UC)是一种慢性非特异性肠道疾病,主要影响结肠和直肠的粘膜和黏膜下层。治疗困难,复发率高且癌变率高。茜草是一种属于茜草科的多年生攀缘藤本植物,在中国和印度有着悠久的应用历史。其地上部分具有多种药理活性,如抗炎、抗癌、抗氧化、止血和抗菌活性。在山西省,茜草地上部分的水煎剂已用于治疗儿童急性腹泻超过一个世纪,具有显著疗效且无毒副作用。该草药本身也是止泻药二泻停的主要成分之一。然而,茜草乙醇提取物(RCEE)有效治疗溃疡性结肠炎(UC)的机制仍不清楚。

 

 

LabEx提供的Luminex检测服务,

 

通过Luminex检测技术测量结肠组织中炎症细胞因子,包括IL-1βIL-6TNF-α的水平。数据使用MILLIPLEXTM Analyst软件进行分析,并通过标准曲线进行量化。所有程序均按照制造商的指南进行。

 

如图所示,模型组小鼠血清中TNF-α47.62 ± 5.64 vs. 8.19 ± 1.27 pg/mg)、IL-6114.89 ± 2.85 vs. 0.54 ± 0.20 pg/mg)和IL-1β3.79 ± 1.05 vs. 0.86 ± 0.10 pg/mg)的水平显著高于正常组。与模型组相比,所有给药组的细胞因子水平均不同程度地降低。

   

RCEE DSS 诱导的溃疡性结肠炎小鼠促炎细胞因子分泌水平的影响。

 

重要发现,

 

在这项研究中,使用DSS成功诱导UC小鼠,然后使用RCEE的不同极性部分进行干预。结果表明,RCEE治疗在体内抑制了结肠中NLRP3炎性体的形成和IL-6/JAK2/STAT3的激活,显著改善了临床症状,包括缓解结肠粘膜损伤和巨噬细胞浸润,抑制炎症细胞因子的释放,并降低了死亡率。总之,这项研究表明,使用RCEE双重抑制NLRP3炎性体和IL-6/JAK2/STAT3通路的激活可能是预防UC进展的有前途的治疗策略。
