Screening of polysaccharides from the differently processed products of Angelica sinensis with the best liver protection effect on chicken and the intervention mechanism study based on tandem mass tag proteomics and multiple reaction monitoring approach.

The incidence of colibacillosis in poultry is on the rise, significantly affecting the chicken industry. Ceftiofur sodium (CS) is frequently employed to treat this disease, resulting in lipopolysaccharide (LPS) buildup. Processing plays a vital role in traditional Chinese veterinary medicine. The potential intervention in liver injury by polysaccharides from the differently processed products of Angelica sinensis (PDPPAS) induced by combined CS and LPS remains unclear. This study aims to investigate the protective effect of PDPPAS on chicken liver injury caused by CS combined with LPS buildup and further identify the polysaccharides with the highest hepatoprotective activity in chickens. Furthermore, the study elucidates polysaccharides' intervention mechanism using tandem mass tag (TMT) proteomics and multiple reaction monitoring (MRM) methods. A total of 190 1-day-old layer chickens were randomly assigned into 12 groups, of which 14 chickens were in the control group and 16 in other groups, for a 10-day trial. The screening results showed that charred A. sinensis polysaccharide (CASP) had the most effective and the best hepatoprotective effect at 48 h. TMT proteomics and MRM validation results demonstrated that the intervention mechanism of the CASP high-dose (CASPH) intervention group was closely related to the protein expressions of FCER2, TBXAS1, CD34, AGXT, GCAT, COX7A2L, and CYP2AC1. Conclusively, the intervention mechanism of CASPH had multitarget, multicenter regulatory features.

A new method providing complementary explanation of the blood-enriching function and mechanism of unprocessed Angelica sinensis and its four kinds of processed products based on tissue-integrated metabolomics and confirmatory analysis.

Angelica sinensis (AS) is a common Traditional Chinese Medicine used for tonifying blood in China. Unprocessed AS and its four kinds of processed products (ASs) are used to treat blood deficiency syndrome in the country. The different blood-tonifying mechanisms of ASs remain unclear. In this work, a novel method integrating metabolomics and hematological and biochemical parameters was established to provide a complementary explanation of blood supplementation mechanism of ASs. Our results revealed that different ASs exhibited various blood supplementation effect, and that AS parched with alcohol demonstrated the best blood supplementation effect. Eight metabolites from liver tissue and 12 metabolites from spleen tissue were considered to be potential biomarkers. These biomarkers were involved in four metabolic pathways. Correlation analysis results showed that l-aspartic acid and l-alanine (spleen tissue), linoleic acid, and l-cystathionine (liver tissue) exhibited a high positive or negative correlation with the aforesaid biochemical indicators. The blood-supplementation effect mechanism of ASs were related to four metabolic pathways. l-Aspartic acid and l-alanine (spleen tissue), linoleic acid, and l-cystathionine (liver tissue) were the four key metabolites associated with the blood supplementation effect of ASs. This study gives a complementary explanation of the blood supplementation effect and mechanism of action of ASs.

[Integrated strategy for mechanism of Baitouweng Decoction in treating dampness-heat diarrhea based on urine metabolomics coupled with network pharmacology].

Baitouweng Decoction is a famous Chinese medicinal decoction that has been used to treat diarrhea over thousands of years. In this study, we investigated the effect and mechanism of Baitouweng Decoction in the treatment of diarrhea. Wistar rats were randomly assigned into 4 groups: control group, dampness-heat diarrhea model group(modeling by complex factors including high-sugar and high-fat diet, improper diet, hot and humid environment, drinking and intraperitoneal injection of Escherichia coli), Baitouweng Decoction(3.6 g·kg~(-1)) group, and self-healing group. A urine metabolomics approach was developed with ultra liquid chromatography-quadrupole-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS) for metabolic profiling. The differential metabolites were screened out by the multivariate comparison between groups. Diarrhea-related protein targets and the active compounds of Baitouweng Decoction were used to predict the protein targets of Baitouweng Decoction. Cytoscape 3.2.1 was employed to establish a active component-target protein interaction network. Three protein-protein interaction(PPI) networks of component target proteins, diarrhea-related proteins, and differential metabolite-related proteins were established and then merged by BisoGenet. ClueGO was used to perform the gene enrichment based on the genetic similarity. The results showed that Baitouweng Decoction effectively treated dampness-heat diarrhea in vivo. N-acetylserotonin, L-gamma-glutamylcysteine, glutathione, retinoate, melatonin, indole-3-acetaldehyde, L-cystine, biotin, and L-tryptophan were screened as differential metabolites in dampness-heat diarrhea model group. Tryptophan metabolism, glutathione metabolism, biotin metabolism, retinol metabolism, and cysteine and methionine metabolism were involved in the therapeutic effect of Baitouweng Decoction in vivo. A total of 167 targets were identified as major candidates for diarrhea progression. The gene-set enrichment revealed that the targets were involved in reactive oxygen species production, inflammation, and apoptosis. Baitouweng Decoction can restrain inflammation, production of reactive oxygen, and block apoptosis, thereby contributing to the treatment of dampness-heat diarrhea.

Urinary metabolomics analysis reveals the effect of volatile oil from Angelica sinensis on LPS-induced inflammation rats.

Lipopolysaccharide (LPS)-induced inflammation occurs commonly and volatile oil from Angelica sinensis (VOAS) can be used as an anti-inflammatory agent. The molecular mechanisms that allow the anti-inflammatory factors to be expressed are still unknown. In this paper, we applied gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography-time-of-flight mass spectrometry (LC-Q/TOF-MS) based on a metabolomics platform coupled with a network approach to analyze urine samples in three groups of rats: one with LPS-induced inflammation (MI); one with intervention with VOAS; and normal controls (NC). Our study found definite metabolic footprints of inflammation and showed that all three groups of rats, MI, intervention with VOAS and NC have distinct metabolic profiles in urine. The concentrations of 48 metabolites differed significantly among the three groups. The metabolites in urine were screened by the GC-MS and LC-Q/TOF-MS methods. The significantly changed metabolites (p < 0.05, variable importance in projection > 1.5) between MI, NC and VOAS were included in the metabolic networks. Finally, hub metabolites were screened, including glycine, arachidonic acid, l-glutamate, pyruvate and succinate, which have high values of degree (k). the Results suggest that disorders of glycine, arachidonic acid, l-glutamate, pyruvate and succinate metabolism might play an important part in the predisposition and development of LPS-induced inflammation. By applying metabolomics with network methods, the mechanisms of diseases are clearly elucidated.

Metabolomics analysis of Pulsatilla decoction on treatment of wetness-heat-induced diarrhea in rats based on UPLC-Q/TOF-MS/MS.

Pulsatilla decoction (PD) is a classical prescription in traditional Chinese medicine that has therapeutic effects on wetness-heat-induced diarrhea (WHD). To investigate the therapeutic effects of PD in the treatment of WHD and elucidate the potential mechanism, we used a metabolomics strategy on the base of ultraperformance liquid chromatography coupled with quadrupole time-of-flight/mass spectrometry (UPLC-Q/TOF-MS/MS) and analyzed the serum samples of 32 rats to identify differential metabolites and pathways associated with the PD treatment of WHD. With variable importance for projection >1.0 in the Orthogonal partial least-squares discriminant analysis (OPLS-DA ) models and FC ≥1.2 or ≤0.8, 67 differential metabolites in the model and control groups and 33 differential metabolites in the model and PD groups were screened. A total of 23 differential metabolites were selected based on Venny analysis. Functional analysis showed that the differential metabolites identified were primarily involved in pentose and glucuronate interconversions, glycerophospholipid metabolism, tryptophan metabolism, starch and sucrose metabolism, and glycerolipid metabolism. This study suggested that PD exerts inhibitory effects on WHD. In particular, the significant roles of PD for treating WHD lie in regulating perturbed energy metabolism, glycerophospholipid metabolism and glycerolipid metabolism, and promoting lysoPC production restoring the function of intestinal tract.

Effects of Tao-Hong-Si-Wu decoction on acute blood stasis in rats based on a LC-Q/TOF-MS metabolomics and network approach.

A novel approach using metabolomics coupled with a metabolic network was used to investigate the effects of Tao-Hong-Si-Wu decoction (THSWD) on the rat model of acute blood stasis syndrome. Acute blood stasis syndrome was induced by placing the rats in ice-cold water following two injections with epinephrine. The hemorheological indicators [whole blood viscosity (WBV) and plasma viscosity (PV)] and the blood coagulation indicators [thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB)] were detected. The nonparametric univariate method and multivariate statistical analysis were performed for determining the potential biomarkers. A correlation map was structured between biochemical indicators and hub metabolites to explain the effects mechanism of THSWD. After the administration of THSWD, the levels of WBV, PV, TT, APTT and FIB returned to levels observed in the control group. According to metabolomics coupled with metabolic network analysis, the intervention of THSWD in rats with acute blood stasis syndrome induced substantial and characteristic changes in their metabolic profiles. Fifteen metabolites were screened, which mainly involved 10 pathways and five hub metabolites, namely, l-glutamate, l-phenylalanine, N-acylsphingosine, arachidonic acid and phosphatidate. The biochemical indicators and hub metabolites could be adjusted to close to normal levels by THSWD. Therefore, combining metabolomics and metabolic network helped to evaluate the effects of THSWD on acute blood stasis.

Objective: To compare the intervention effects of volatile oils from different preparations of Angelica sinensis root on acute inflammation induced by lipopolysaccharide in rats. Methods: Acute inflammation model was induced by intraperitoneal injection of lipopolysaccharide( 100 µg/kg) in rats. Blood and serum inflammatory mediators and cytokines were detected, combining with the pathological histological observation of lung and liver to evaluate the anti-inflammatory activities of volatile oils from parching Angelica sinensis root with wine( J-VOAS),volatile oils from charred Angelica sinensis root( C-VOAS) and Angelica sinensis root( S-VOAS). Results: Compared with control group, the WBC count, the percentage of NE and PLT count in acute inflammation model group significantly increased ( P < 0. 05),and the percentage of LY significantly decreased( P < 0. 05); the content of IL-1ß,IL-6,NO and TNF-α significantly increased( P < 0. 001) and content of IL-10 significantly decreased( P < 0. 05) in model group; after J-VOAS,C-VOAS and S-VOAS intervention, the blood routine index and serum inflammatory mediators and cytokines significantly reversed( P < 0. 05). The pathological histological study showed that expanded alveoli, massive inflammatory cells infiltration in alveoli and pulmonary interstitium, the liver leaflets diffuse necrosis, hepatic cord derangement, and some of the liver cells degeneration and edema in model group; after J-VOAS intervention, their pathological changes significantly reduced. Conclusion: All volatile oils from different preparations of Angelica sinensis root had intervention on acute inflammation induced by LPS. And J-VOAS had the best effect, followed by C-VOAS and S-VOAS.

[Metabolomic evaluation for anti-inflammatory effect of volatile oils from different preparations of Angelicae Sinensis Radix].

To evaluate the anti-acute inflammation effects of volatile oils from different processed products of Angelicae Sinensis Radix(AS) in the rat model of acute inflammation established by the metabolomic method. Volatile oil of charred AS (C-VOAS), wine-processed AS (J-VOAS), locally processed AS (T-VOAS) and oil-process AS (Y-VOAS) were applied to intervene the rat acute paw swelling inflammation model induced by Carrageenan. Changes in serum HIS, 5-HT, PGE2 and TNF-α content in rats were detected. Gas chromatography-mass spectrometry was used to detect the metabolites in plasma. Potential biomarkers were investigated according to principal component analysis method and partial least-squares discriminant analysis. According to the results, C-VOAS and J-VOAS could significantly inhibit inflammatory mediators Histamine, 5-hydroxytryptamine, prostaglandin-E2 and cytokine tumor necrosis factor-alpha (P<0.01), and T-VOAS and Y-VOAS also showed a significantly inhibitory effect (P<0.05). Compared with the normal group, 14 endogenous metabolite biomarkers showed metabolic disturbance in plasma (P<0.05 or P<0.01). Compared with acute inflammation model group, C-VOAS and J-VOAS could better recover the levels of the endogenous metabolites (P<0.05 or P<0.01) than T-VOAS and Y-VOAS (P<0.05 or P<0.01). This study suggests that C-VOAS and J-VOAS show a better anti-inflammatory effect than T-VOAS and Y-VOAS. Therefore, the metabolomic method could be used to expound the anti-inflammatory mechanism of volatile oils from different processed products of AS, and provide a theoretical basis for clinical application of VOAS.

[Effect of different processed volatile oils from Angelica sinensis on urinary metabolomics rats].

Different processed volatile oils from AS on urine metabolites of normal rats were analyzed to reveal the possible metabolic pathways. Totally 50 male Waster rats were randomly divided into normal control group, C-ASVO group, J-ASVO group, T-ASVO group and Y-ASVO group, with 10 rats in each group. The normal group was given isovolumetric 0.5% polyoxyethylene sorbitan fatty acid ester（Tween-80）, while the other groups were given 0.176 mL•kg⁻¹ different processed volatile oils from AS. Drugs were given for 3 successive days. The urine was collected at 48 h with metabolic cages. GC-MS was employed to detect the metabolic fingerprint of rat urine in different times. Principal component analysis(PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) were adopted for a multivariate statistical analysis. Metabolites with potential differences were selected based on the results of variable importance in the projection(VIP) and t test. The metabolic pathway analysis(MetPA) database was built for different metabolites' metabolic pathways. The results showed that compared with the normal group, 31 kinds of endogenous metabolites in the different processed volatile oils from AS groups change significantly(P<0.05). And there were differences in normal rat urine metabolites among the different processed volatile oils from AS, of which the influence degree of J-ASVO was slightly stronger than C-ASVO, T-ASVO, and Y-ASVO. Therefore, the metabolism effect may be focused on energy metabolism, amino acid metabolism, fatty acid metabolism and glucose metabolism. This study focused on metabolism and mechanism of different processed volatile oils from AS, and provided new ideas for pharmacological actions of traditional Chinese medicines.

Metabonomic analysis of the anti-inflammatory effects of volatile oils of Angelica sinensis on rat model of acute inflammation.

Metabonomics based on GC-MS was used to study the possible anti-inflammatory mechanisms of volatile oils of Angelica sinensis (VOAS) in rats with acute inflammation. Acute inflammation was induced by subcutaneous injection of carrageenan in rats. The levels of prostaglandin E2 (PGE2 ), histamine (HIS) and 5-hydroxytryptamine (5-HT) in the inflammatory fluid were detected. Principal component analysis and orthogonal partial least squares-discriminant analysis models were performed for pattern recognition analysis. After the administration of VOAS, the levels of PGE2 , HIS, and 5-HT returned to levels observed in normal group. According to GC-MS analysis, the intervention of VOAS in rats with acute inflammation induced substantial and characteristic changes in their metabolic profiles. Fourteen metabolite biomarkers, namely, lactic acid, malic acid, citric acid, trans-dehydroandrosterone, aldosterone, linoleic acid, hexadecanoic acid, pregnenolone, octadecenoic acid, myristic acid, l-histidine, octadecanoic acid, arachidonic acid (AA) and l-tryptophan, were detected in the inflammatory fluid. The levels of all biomarkers either increased or decreased significantly in model groups. VOAS possibly intervened in the metabolic process of inflammation by altering histidine metabolism, tryptophan metabolism, AA metabolism, steroid hormone biosynthesis, fatty acid metabolism and energy metabolism. Metabonomics was used to reflect an organism's physiological and metabolic state comprehensively, and it is a potentially powerful tool that reveals the anti-acute-inflammatory mechanism of VOAS.

[Discrimination of polysaccharides from Angelica sinensis and its different processed products based on Fourier transform infrared spectroscopy].

A new rapid and nondestructive method for identifying polysaccharides from Angelica sinensis and its different processed products was developed, and this method was based on Fourier transform infrared spectroscopy (FTIR). In the clinic of traditional Chinese medicine, unprocessed Angelica sinensis(UAS) is of ten used after processed, the common processed products are Angelica sinensis parched with wine(WAS), Angelica sinensis parched with soil(SAS), Angelica sinensis parched with oil(OAS) and Charred Angelica sinensis(CAS). In order to use polysaccharides from Angelica sinensis and its processed products effectively and reasonably in clinic, it is very necessary to identify them. FTIR of polysaccharides from Angelica sinensis and its different processed products was determined, and then it was decomposed by discrete wavelet transform (DWT). The high frequency information in scale 2, 3 and 4 was selected as feature information, from which the each wavelet entropy was extracted as characteristic value. BP neural network was trained with these characteristic values. The trained BP neural network was used to identify polysaccharides from Angelica sinensis and its different processed products. According to 30 prediction samples, the correct rate for recognition was 93. 3%, which indicates that: it has better feasibility to identify polysaccharides from Angelica sinensis and its different processed products by this method, which is based on FTIR, discrete wavelet transform and BP neural network

[Comparative metabonomics study on urine in rat treated by Angelica sinensis volatile oil].

Metabonomics was employed to investigate the effect of Angelica sinensis volatile oil (ASVO) to the endogenous metabolites of normal rats, and to reveal the possible ways of metabolism in rats caused by ASVO. The fifty male Waster rats were randomly divided into five groups (each consists of 10 rats), such as control group, high dose group of ASVO, middle dose group of ASVO, low dose group of ASVO, and Aspirin group. They were given 0.9% saline, 0.352 mL x kg(-1) ASVO, 0.176 mL x kg(-1) ASVO, 0.088 mL x kg(-1) ASVO and ASP respectively with the equal volume of 0.2 mL. Drugs and vehicle were given for 3 successive days. The urine was collected at 12, 24, 36, 48 h after modeling with metabolic cages. Rat urine metabolic fingerprint in different stages was analyzed using GC-MS, based on which the principal component analysis (PCA)and orthogonal partial least-squares discriminant analysis (OPLS-DA) models were established for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. It was revealed that the middle dose of ASVO at 36 h induces a substantial change in rat urine. Compared with control group, seven kinds of endogenous metabolites in ASP group and ASVO group change significantly (P < 0.05), among which aconitic acid, succinic acid, citric acid, alpha-ketone glutaric acid, glycine and malic acid content had an upward trend (P < 0.05) and prostaglandin content had a downward trend (P < 0.01). The mechanism of ASVO and ASP have the similarity. It is likely that ASVO intervenes the metabolic process by affecting the energy, amino acid and lipid metabolism. Our work also indicates that rats administrated with ASVO can increase the energy metabolism of the body, induce the production of inflammatory substances and strengthen the body's immune ability. The result has also provide a proof for futher interpret ASVO pharmacological effects.

Research on the mechanism of Guanyu Zhixie Granule in intervening gastric ulcers in rats based on network pharmacology and multi-omics.

Objective: Guanyu Zhixie Granule (GYZXG) is a traditional Chinese medicine compound with definite efficacy in intervening in gastric ulcers (GUs). However, the effect mechanisms on GU are still unclear. This study aimed to explore its mechanism against GU based on amalgamated strategies. Methods: The comprehensive chemical characterization of the active compounds of GYZXG was conducted using UHPLC-Q/TOF-MS. Based on these results, key targets and action mechanisms were predicted through network pharmacology. GU was then induced in rats using anhydrous ethanol (1 mL/200 g). The intervention effects of GYZXG on GU were evaluated by measuring the inhibition rate of GU, conducting HE staining, and assessing the levels of IL-6, TNF-α, IL-10, IL-4, Pepsin (PP), and epidermal growth factor (EGF). Real-time quantitative PCR (RT-qPCR) was used to verify the mRNA levels of key targets and pathways. Metabolomics, combined with 16S rRNA sequencing, was used to investigate and confirm the action mechanism of GYZXG on GU. The correlation analysis between differential gut microbiota and differential metabolites was conducted using the spearman method. Results: For the first time, the results showed that nine active ingredients and sixteen targets were confirmed to intervene in GU when using GYZXG. Compared with the model group, GYZXG was found to increase the ulcer inhibition rate in the GYZXG-M group (p < 0.05), reduce the levels of IL-6, TNF-α, PP in gastric tissue, and increase the levels of IL-10, IL-4, and EGF. GYZXG could intervene in GU by regulating serum metabolites such as Glycocholic acid, Epinephrine, Ascorbic acid, and Linoleic acid, and by influencing bile secretion, the HIF-1 signaling pathway, and adipocyte catabolism. Additionally, GYZXG could intervene in GU by altering the gut microbiota diversity and modulating the relative abundance of Bacteroidetes, Bacteroides, Verrucomicrobia, Akkermansia, and Ruminococcus. The differential gut microbiota was strongly associated with serum differential metabolites. KEGG enrichment analysis indicated a significant role of the HIF-1 signaling pathway in GYZXG's intervention on GU. The changes in metabolites within metabolic pathways and the alterations in RELA, HIF1A, and EGF mRNA levels in RT-qPCR experiments provide further confirmation of this result. Conclusion: GYZXG can intervene in GU induced by anhydrous ethanol in rats by regulating gut microbiota and metabolic disorders, providing a theoretical basis for its use in GU intervention.

Pulsatilla decoction alleviates DSS-induced UC by activating FXR-ASBT pathways to ameliorate disordered bile acids homeostasis.

Ethnopharmacological relevance: Pulsatilla decoction (PD) is a classical prescription for the treatment of ulcerative colitis. Previous studies have demonstrated that the therapeutic efficacy of PD is closely associated with the activation of Farnesoid X receptor (FXR). The activity of FXR is regulated by apical sodium-dependent bile acid transporter (ASBT), and the FXR-ASBT cascade reaction, centered around bile acid receptor FXR, plays a pivotal role in maintaining bile acid metabolic homeostasis to prevent the occurrence and progression of ulcerative colitis (UC). Aim of the study: To elucidate the underlying mechanism by which PD exerts its proteactive effects against Dextran Sulfate Sodium Salt (DSS)-induced ulcerative colitis, focusing on the modulation of FXR and ASBT. Materials and methods: To establish a model of acute ulcerative colitis, BALB/C mice were administered 3.5% DSS in their drinking water for consecutive 7 days. The disease activity index (DAI) was employed to evaluate the clinical symptoms exhibited by each group of mice. Goblet cell expression in colon tissue was assessed using glycogen schiff periodic acid-Schiff (PAS) and alcian blue staining techniques. Inflammatory cytokine expression in serum and colonic tissues was examined through enzyme-linked immunosorbent assay (ELISA). A PCR Array chip was utilized to screen 88 differential genes associated with the FXR-ASBT pathway in UC treatment with PD. Western blotting (WB) analysis was performed to detect protein expression levels of differentially expressed genes in mouse colon tissue. Results: The PD treatment effectively reduced the Disease Activity Index (DAI) score and mitigated colon histopathological damage, while also restoring weight and colon length. Furthermore, it significantly alleviated the severity of ulcerative colitis (UC), regulated inflammation, modulated goblet cell numbers, and restored bile acid balance. Additionally, a PCR Array analysis identified 21 differentially expressed genes involved in the FXR-ASBT pathway. Western blot results demonstrated significant restoration of FXR, GPBAR1, CYP7A1, and FGF15 protein expression levels following PD treatment; moreover, there was an observed tendency towards increased expression levels of ABCB11 and RXRα. Conclusion: The therapeutic efficacy of PD in UC mice is notable, potentially attributed to its modulation of bile acid homeostasis, enhancement of gut barrier function, and attenuation of intestinal inflammation.

Baitouweng Tang ameliorates DSS-induced ulcerative colitis through the regulation of the gut microbiota and bile acids via pathways involving FXR and TGR5.

In China, Baitouweng Tang (BTWT) is a commonly prescribed remedy for the treatment of ulcerative colitis (UC). Herein, the present study aims to assess the anti-colitis activity of BTWT and its underlying mechanisms in UC BALB/c mice. Induction of UC in BALB/c mice was carried out by adding 3.5% DSS in the drinking water of underlined mice. After UC induction, the mice were administrated with BTWT for 7 days. Clinical symptoms were assessed, followed by analyzing the bile acids (BAs) in serum, liver, colon, bile, and feces of UC mice through UPLC-MS/MS. The modified 16S rDNA high-throughput sequencing was carried out to examine the gut microbiota of feces. BTWT significantly improved the clinical symptoms such as and histological injury and colon shortening in UC induced mice. Furthermore, BTWT remarkably ameliorated colonic inflammatory response. After BTWT treatment, the increased concentrations of UDCA, HDCA, αMCA, ßMCA, CA, and GLCA in UC were decreased, and the levels of some BAs, especially CA, αMCA, and ßMCA were normalized. Moreover, the relative species abundance and gut microbiota diversity in the BTWT-exposed groups were found to be considerably elevated than those in the DSS-treated group. BTWT increased the relative abundance of Firmicutes, Proteobacteria, Actinobacteria, Tenericutes, and TM7, which were statistically lower in the fecal microbiota of UC mice. The relative abundance of Bacteroidetes was found to be elevated in the DSS group and normalized after BTWT treatment. BTWT increased the expression of FXR and TGR5 in the liver. BTWT administration improved DSS-induced mice signs by increasing the TGR5 and FXR expression levels. This result was achieved by the regulation of the BAs and gut microbiota.
