Abstract The study aimed to investigate the ameliorative effect of salidroside (SAL) on the crosstalk among liver metabonomics, gut barrier function and bile acids in furan-induced mice. Forty male mice were randomly divided into the following five groups: CON, FUR 8 (8 mg/kg/day furan), SAL 10 (8 mg/kg/day furan+10 mg/kg/day SAL), SAL 20 (8 mg/kg/day furan+20 mg/kg/day SAL), and SAL 40 (8 mg/kg/day+40 mg/kg/day SAL). Mice were administered with furan for 30 days and SAL was administered for 15 days from day 16. Principal components analysis (PCA) and heatmap were employed to probe metabonomics profile alterations in liver tissues and select thirty-eight potential biomarkers. Pathway analysis revealed primary bile acids were largely changed in the biosynthesis pathway. Moreover, SAL regulated the activation of farnesoid X receptor (FXR), downregulating hepatic heterodimer partner (SHP), upregulating cholesterol 7a-hydroxylase (CYP7A1) as well as decreasing the expression of portal fibroblast growth factor 15 (FGF15), compared to the furan-treated group. Importantly, SAL dramatically increased the level of tight junction proteins, as immunohistochemistry results show. In conclusion, the ameliorative effects of SAL on liver damage induced by furan might be due to altered gut barrier function, while FXR signaling acted a significant role in the function of SAL.

Abstract Studies have shown that 8-epidiosbulbin E acetate (EEA), a major diterpenoid lactone in the tuber of Dioscorea bulbifera, can induce hepatotoxicity in vivo. However, the underlying mechanisms remain unknown. Using the integrated transcriptomic and metabolomics method, in this study we investigated the global effect of EEA exposure on the transcriptomic and metabolomic profiles in mice. The abundance of 7131 genes and 42 metabolites in the liver, as well as 43 metabolites in the serum we...

Abstract Safety concerns arising from the consumption of foods derived from genetically modified (GM) crops remains a controversial subject. We report here a faecal microbiota compositional analysis in Wistar rats from the GMO90 + study, which fed glyphosate-tolerant NK603 (+/− Roundup application) and Bt toxin MON810 GM maize for 6 months in comparison to their closest non-GM isogenic lines. We first integrated the faecal microbiota compositional data with results from plasma metabolomics to un...

Abstract In our study, the ameliorative effect of salidroside (SAL) from Rhodiola Rosea L. on the intestinal microflora subject to furan-induced liver injury in a mouse model was investigated by 16 S rDNA, oxidative indexes, LPS and cytokine levels. The results demonstrated that SAL alleviated hepatic oxidative injury by inhibiting the activities of AST, ALT and the content of MDA, and promoting the activities of SOD, GSH and GST, compared to the furan-treated group. SAL significantly modified t...

Objective(s): To reveal the detailed mechanism underlying the functions of salidroside on the inflammation of intestinal epithelial cells during IBD.Materials and Methods: Quantitative real-time PCR was employed to assess the expression of IL-6, IL-10, and α-defensins 5 and 6. ELISA assay was performed to measure the secretion of IL-6 and IL-10. MTT assay was used to determine the cell viability and proliferation. Western blot was used to assess the phosphorylation of NF-kB, Erk1/2, JNK, P38, JA...

Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis, is the leading cause of mortality worldwide due to a single infectious agent. The pathogen spreads primarily via aerosols and especially infects the alveolar macrophages in the lungs. The lung has evolved various biological mechanisms, including oxidative stress (OS) responses, to counteract TB infection. M. tuberculosis infection triggers the generation of reactive oxygen species by host phagocytic cells (primarily macrophag...

Our previous studies suggested that salidroside could alleviate hepatic steatosis in type 2 diabetic C57BLKS/Leprdb (db/db) mice. The aim of the present study was to evaluate the therapeutic effect of salidroside on high-fat diet- (HFD-) induced nonalcoholic fatty liver disease (NAFLD) by investigating underlying mechanisms. Mice were fed with HFD or regular diet, randomly divided into two groups, and treated with salidroside or vehicle for 8 weeks. Then, biochemical analyses and histopathologic...

Abstract Bile acids are steroid acids found in the bile of mammals. The bile acid conjugate tauroursodeoxycholic acid (TUDCA) is neuroprotective in different animal models of stroke and neurological diseases. We have previously shown that TUDCA has anti-inflammatory effects on glial cell cultures and in a mouse model of acute neuroinflammation. We show now that microglial cells (central nervous system resident macrophages) express the G protein-coupled bile acid receptor 1/ Takeda G protein-coup...

Intestinal ischemia reperfusion (I/R) injury caused by severe trauma, intestinal obstruction, and operation is one of the tough challenges in clinic. 6-Gingerol (6G), a main active ingredient of ginger, is found to have anti-microbial, anti-inflammatory, anti-oxidative, and anti-cancer activities. The present study was designed to characterize the potential protective effects of 6G on rat intestinal I/R injury and reveal the correlated mechanisms. Rat intestinal I/R model was established with cl...

The intestinal epithelial barrier includes columnar epithelial, Paneth, goblet, enteroendocrine, and tuft cells as well as other cell populations, all of which contribute properties essential for gastrointestinal homeostasis. The intestinal mucosa is covered by mucin, which contains antimicrobial peptides and secretory IgA and prevents luminal bacteria, fungi, and viruses from stimulating intestinal immune responses. Conversely, the transport of luminal microorganisms—mediated by M, dendritic, a...

Hepatic fibrosis (HF) is a typical consequence of various chronic liver diseases, and there is still no ideal drug for its treatment. Yinchen Wuling Powder (YCWLP), a famous traditional Chinese medicine prescription, is effective for the treatment of icteric hepatitis, hepatic fibrosis, non-alcoholic fatty liver disease and other liver diseases in clinical practices, however, the underlying mechanisms of YCWLP on HF is still unclear. In this study, 1H NMR and MS-based metabolomics analysis along...

Food contaminants represent food constituents that are accidentally introduced during food preparation cycle. In addition to their direct toxic effects on human health at different levels, they influence both gut microbiota composition and function. This often leads to metabolic disorders linked to many aspects of the human body. Foods are poisoned with physical, chemical, or biological factors either in agriculture or during processing steps. These include naturally occurring compounds such as ...
