Porphyra tenera (PT) is a functional seaweed food that has been reported for health benefits such as antioxidant, immunostimulant, anti-inflammation, and hepatoprotective effects. In this study, we investigated the effect of PT extracts on gut microbiota modulation in colitis-induced mice. The mice experiment was designed as three groups including normal mice (CTL), dextran sodium sulfate (DSS)-fed mice, and DSS plus PT extracts-fed mice (PTE). DSS was administrated through drinking water containing DSS for 1 week, and the PT extract was ingested into the gastrointestinal tract in mice. PT extract ameliorated the decreased body weight and colon length and improved disease activity index and pro-inflammatory cytokine expression. In addition, PT extract significantly shifted the gut microbiota of mice. DSS treatment significantly increased the portion of harmful bacteria (i.e., Helicobacter, Mucipirillum, and Parasutterella) and decreased the butyrate producing bacteria (i.e., Acetatifactor, Alistipes, Oscillibacter, and Clostridium_XIVb). PT extract increased the abundance of genera Clostridium_XIVb and also enriched some of predicted metabolic activities such as glyoxylate cycle, ethylmalonyl-CoA pathway, nitrate reduction, creatinine degradation, and glycine betaine metabolism. These results suggest that PT extract may ameliorate the DSS-induced colitis inflammation through regulating the compositions and functions of gut microbiota in mice.

The effect ofCordyceps militaris(CM) grown on germinated soybeans (GSC) in the inflammatory bowel disease (IBD) model was studied. To demonstrate the preventive effect of GSC extract in a dextran-sodium-sulfate- (DSS-) induced acute colitis mouse model, GSC was administered 2 days before DSS coadministration. GSC significantly suppressed DSS-induced disease activity index (DAI) as well as histopathological scores, compared to control or CM-treated group. To elucidate the anti-IBD activity of GSC, we checked the level of matrix metalloproteinases (MMPs) and inflammatory mediators. GSC extract decreased the level of MMP-3 and -9 mRNAs and p53 proteins. The level and activity of LPS-induced MMP-9 were reduced in GSC-treated RAW264.7 cells. It also attenuated the level of inducible nitric oxide synthase (iNOS) and tumor necrosis factor- (TNF-)αmRNAs both in colon tissue and in macrophage cells. These results suggest that GSC can be applied as a protective agent against IBDs.

Abstract Crohn’s and ulcerative colitis are common inflammatory conditions associated with Inflammatory bowel disease. Owing to the importance of diet based approaches for the prevention of inflammatory gut conditions, the present study was aimed to screen the human isolates of Bifidobacterium strains based on their ability to reduce LPS-induced inflammation in murine macrophage (RAW 264.7) cells and to evaluate prioritized strains for their preventive efficacy against ulcerative colitis in mice. Twelve out of 25 isolated strains reduced the production of LPS-induced nitric oxide and inflammatory cytokines. Furthermore, three strains, B. longum Bif10, B. breve Bif11, and B. longum Bif16 conferred protection against dextran sodium sulfate induced colitis in mice. The three strains prevented shortening of colon, spleen weight, percentage body weight change and disease activity index relative to colitis mice. Lower levels of Lipocalin-2, TNF-α, IL-1β and IL-6 and improved SCFA levels were observed in Bifidobacterium supplemented mice relative to DSS counterparts. Bacterial composition of B. longum Bif10 and B. breve Bif11 fed mice was partly similar to the normal mice, while DSS and B. longum Bif16 supplemented mice showed deleterious alterations. At the genus level, Bifidobacterium supplementation inhibited the abundances of pathobionts such as Haemophilus, Klebsiella and Lachnospira there by conferring protection.

Background: Objective of this study was to evaluate anti-inflammatory properties of a novel standardized Boswellia serrata extract–bsRx (developed using natural excipients and designed to have specific ratio of its major actives, viz. AKBA and BBA) in dextran sodium sulfate (DSS)-induced IBD model in BALB/c mice.Methods: Animals (BALB/c mice) in control (CL) group were administered vehicle; DSS-induced colitis group (DSS group), 2.5 % DSS; and Boswellia serrata group (BS group) received DSS, for inducing colitis, together with a novel standardized extract of Boswellia serrata (41 mg/kg, 4.1 mg/ml solution in distilled water) for 10 days. Reference group (SS group) received DSS with sulfasalazine (30 mg/kg, 3.0 mg/ml suspension in distilled water) for 10 days. Clinical assessment for disease activity index (DAI), histopathological examination and hematological assessments were performed.Results: Treatment with Boswellia serrata showed significant reduction in the DAI score on day 10 compared to the DSS group (2.49±0.93 versus 3.63±0.55, p≤0.05). Body weight (18.54±2.21 gm versus 17.05±3.53 gm) and colon length (6.8±0.9 cm versus 7.6±0.6 cm, p≤0.05) also improved in the BS group compared to DSS group, respectively. Histological scoring of colitis was lower in the BS group (10.1±1.37). There was no difference in leukotriene levels between groups (p>0.05).Conclusions: Treatment with novel Boswellia serrata extract improved colon length, DAI and histological scoring index in DSS-induced colitis in IBD mice models. Our results indicate the promising potential of novel Boswellia extract in IBD and gut health management.

Abstract Salvia miltiorrhiza (SM, or Danshen) extract has been approved by China FDA for the treatment of cardiovascular and cerebrovascular diseases owing to its potent anti-inflammatory effects. Whether SM may be used to treat inflammatory bowel disease (IBD) remains elusive. In the current study, Dextran-Sodium-Sulfate (DSS) induced colitis in mice was used as a model of IBD, and SM was given orally for 7 days. SM administration has significantly reduced the disease activity index (DAI) score and weight lost and colon shortening in the DSS-induced colitis mice. The macrophage infiltration was significantly reduced in the SM treatment group. To explore the mechanisms, macrophage processor cell line Raw 264.7 was used to verify the anti-inflammatory effect of SM. SM treatment inhibited lipopolysaccharide (LPS)-induced macrophage activation in RAW264.7 cells and significantly reduced the production of pro-inflammatory factors. The current study provided evidence that oral administration of SM ameliorates pathological deterioration of IBD in mice, and warrants future clinical application of SM for the management of IBD.

Abstract Background and Aims: Dextran-sodium sulfate and 2,4,6-trinitrobenzene sulphonic acid are common modeling methods in studying ulcerative colitis. Little attention has been paid to the mechanism differences between the two approaches. Here, we aim to compare the mechanisms and efficacy of these two models and wish to provide fundamental proves for choosing ideal ulcerative colitis models. Methods: Dextran-sodium sulfate and 2,4,6-trinitrobenzene sulphonic acid were applied to induce the colitis in C57BL/6 mice for seven days. Body weight and disease activity index were assessed. Hematology was detected by routine blood test. Histopathology was analyzed by hematoxylin-eosin staining section. Enzyme-linked immunosorbent assay, Western blot and quantitative real-time PCR were used to detect the cytokines protein levels and mRNA levels. Flow cytometry were used to detect the cycles and subsets of splenic cells. Results: Dextran-sodium sulfate induced colitis in C57BL/6 mice showed higher acute immune activities, while 2,4,6-trinitrobenzene sulphonic acid induced colitis showed chronic immune activities with high platelet amounts and activation. Dextran-sodium sulfate is more suitable for modeling acute ulcerative colitis. On the contrary, 2,4,6-trinitrobenzene sulphonic acid is more appropriate for modeling chronic ulcerative colitis. Conclusions: Dextran-sodium sulfate treatment within 7 days in C57BL/6 mice is a suitable experimental model for studying human acute ulcerative colitis with immune response, fecal blood and acute pathogenic damage. Conversely, 2,4,6-trinitrobenzene sulphonic acid treatment within 7 days is more appropriate for studying human chronic ulcerative colitis with hypercoagulable state, IL-2 over-expression state and chronic pathogenic damage.

Chronic Inflammatory Disorder

Abstract Inflammatory bowel disease (IBD), which consists of ulcerative colitis (UC) and Crohn's disease (CD), is a chronic inflammatory disorder of the gastrointestinal tract. Occurrence and development of UC have been associated with multiple potential causative factors, which include fungal dysbiosis. Growing evidence reveals that Candida albicans-associated dysbiosis is correlated with clinical deterioration in UC. Paeonol (PAE) is a commonly used traditional medicine with multiple reported properties including effective alleviation of UC. In this study, a murine UC model was established by colonizing mice with additional C. albicans via gavage prior to dextran sodium sulfate (DSS) administration. Effects of PAE treatment were also assessed at initiation and in preestablished C. albicans-associated colitis. The results showed that C. albicans supplementation could aggravate disease activity index (DAI), compromise mucosal integrity, exacerbate fecal and tissue fungal burdens, increase serum β-glucan and anti-Saccharomyces cerevisiae antibody (ASCA) levels, promote serum and colonic tissue pro-inflammatory cytokine secretion (tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-8) and decrease the anti-inflammatory cytokine IL-10 level. It also stimulated Dectin-1, TLR2 and TLR4 as well as expression of their downstream effector NF-κB in colonic tissue. After PAE treatment, the adverse impacts of C. albicans on colitis were relieved, via decreased receptor-associated local and systemic inflammation. Our study suggests that PAE should be a candidate for treatment of fungal dysbiosis-associated UC and may act through the Dectin-1/NF-κB pathway in collaboration with TLR2 and TLR4. Lay Summary Candida albicans is believed to be an important stimulator in ulcerative colitice (UC) development. Suppressing the growth of intestinal C. albicans can be contributory to the amelioration of UC. Paeonol (PAE) is a commonly used traditional medicine with multiple biological functions. In this study, we observed that PAE could alleviate symptoms in mice UC model accompanying with burden reduction of C. albicans. Therefore, we suppose that PAE can be a candidate in the treatment of C. albicans-associated UC.

Background/Aims: There are known links between inflammatory bowel disease (IBD) and changes in the microbiota of the gut and inflammation and oxidative stress. In this study, a colitis model induced by dextran sodium sulfate (DSS) in mice is used to evaluate whether the presence of bioactive peptides IRW (Ile-Arg-Trp) and IQW (Ile-Gln-Trp) peptides is advantageous. Methods: The mice were arbitrarily assigned to the following four groups: (i) control (untreated), (ii) dextran sodium sulfate (DSS) treated, (iii) IRW-DSS treated, and (iv) IQW-DSS treated. For 7 days, the control group subjects had unrestricted access to untreated drinking water, whereas the drinking water supplied to the subjects in the DSS, IRW-DSS, and IQW-DSS groups during this period consisted of 5% DSS solution. The colonic lesions were scored after hematoxylin and eosin staining. Serum antioxidant capacity was analyzed by 2,2’-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical cation decolorization test and the microbiota in the colonic contents were sequenced by HiSeq2500 PE250. Results: The presence of DSS reduced daily weight gain, enhanced histopathology scores, and inhibited antioxidant enzyme expression. Superoxide dismutase, catalase, and glutathione peroxidase activities in the DSS-induced colitis model were significantly enhanced (P < 0.05) in the presence of dietary IRW and IQW. Furthermore, the Simpson index was significantly increased (P < 0.05) in the presence of dietary IRW and IQW compared to the control group. IRW and IQW increased the abundance of Coprococcus_1, Ruminococcaceae_UCG-014, and Desulfovibrio compared to the control group and DSS group. Furthermore, IQW decreased the abundance of Bacteroides in relation to the control group, but increased Parabacteroides. In addition, IRW increased the level of Anaerotruncus, Oscillibacter, and Ruminiclostridium_9 compared to the control group. Conclusion: This study concludes that the presence of IRW or IQW can mitigate DSS-induced oxidative stress by improving the activities of antioxidant enzymes, increasing intestinal microbial diversity and enhancing the abundance of gut microbiota, which may help maintain the homeostasis of host health and microenvironment in a DSS-induced mouse model, thus providing a potential further treatment for IBD patients.
