Project description:In this study we investigated whether gut microbiota profile of Italian healthy volunteers could differ based on their geaographical origin. To this purpose, fecal samples were collected from 31 healthy individuals living in 3 different italian regions (Lombardy, North; Lazio, Center; Apulia, South) and their respective microbiota profiles were analyzed employing 16S metagenomic sequencing method. This study identifies differences in the gut microbiota content and richness among individuals with the same ethnicity coming from three different Italian regions.

Project description:The understanding of the effects of compounds on the gut microbiome is limited and in particular we don’t know whether structurally similar compounds have similar or distinct effects on the gut microbiome. Here we selected berberine (BBR), an isoquinoline quaternary alkaloid, and sixteen structural analogues, and evaluated their effects on in vitro cultured individual gut microbiomes. The responses of the individual microbiomes were evaluated by metaproteomic profiles and by assessing butyrate production. BBR and eight analogues led to changes in proteins involved in microbial defense and stress responses, and enrichment of proteins from Verrumicrobia, Proteobacteria and Bacteroides phyla. It also led to a decrease in proteins from the Firmicutes phylum and its Clostridiales order which correlated to decrease proteins involved in the butyrate production pathway and butyrate concentration. Three of the compounds, Sanguinarine, Chelerythrine and Ethoxysanguinarine activated bacterial protective mechanisms, enriched Proteobacteria, increased opacity proteins and markedly reduced butyrate production. Dihydroberberine had a similar function to BBR in enriching the Akkermansia genus. In addition, it showed less overall adverse impacts on the functionality of the gut microbiome, including a better maintenance of the butyrate level. Our study shows that ex vivo microbiome assay can assess differential regulating effects of compounds with subtle differences and reveals that compound analogues can have distinct effects on the microbiome.

Project description:We have previously demonstrated that the gut microbiota can play a role in the pathogenesis of conditions associated with exposure to environmental pollutants. It is well accepted that diets high in fermentable fibers such as inulin can beneficially modulate the gut microbiota and lessen the severity of pro-inflammatory diseases. Therefore, we aimed to test the hypothesis that hyperlipidemic mice fed a diet enriched with inulin would be protected from the pro-inflammatory toxic effects of PCB 126.

Project description:Early life gut microbiota plays a critical role in gut development, maturation of the immune response and protection against enteric pathogens such as Salmonella. In this study, we investigated how different gut microbiota compositions influence the host transcriptomic signatures and susceptibility to Salmonella infection in chicks.

Project description:Objective: Benzbromarone (BBR) is an effective uric acid-lowering drug. However, it can induce severe liver damage in some patients. Studies have shown that BBR specifically exacerbates hepatic steatosis in obese individuals, leading to aggravated liver injury. The exact mechanism behind this phenomenon remains unclear. Methods: db/db mice were divided into four groups: Control, BBR administration (BBR), Pparg knockdown (Pparg-KD), and BBR administration with Pparg knockdown (BBR + Pparg-KD). One week after AAV8-shRNA-Pparg virus injection, mice were orally administered BBR for four weeks, and changes in blood glucose and body weight were measured. Subsequently, samples were collected, and plasma lipid levels, hepatic lipid content, and liver function parameters were determined. RNA-seq was performed to assess changes in the hepatic gene expression profile and analyze the protective effect of PPARγ knockdown on BBR-induced drug-induced liver injury. Results: Mice in the BBR group exhibited more severe levels of plasma lipids, hepatic lipids, and liver function parameters compared to the Control group. However, mice in the BBR + Pparg-KD group showed significant improvements in these indicators compared to the BBR group. Transcriptomic analysis revealed that BBR administration upregulated the expression of various lipid synthesis-related genes, primarily associated with the PPAR signaling pathway. Furthermore, PPARγ knockdown reversed the increased expression of these lipid synthesis genes. This suggests that PPARγ knockdown has a significant protective effect against BBR-induced drug-induced liver injury. Conclusion: Hepatocyte-specific knockdown of PPARγ can protect against BBR-induced exacerbation of hepatic steatosis and liver injury by inhibiting the promotion of lipid synthesis through PPARγ activation.

Project description:Intracerebral hemorrhage (ICH) induces alterations in the gut microbiota composition, significantly impacting neuroinflammation post-ICH. However, the impact of gut microbiota absence on neuroinflammation following ICH-induced brain injury remain unexplored. Here, we observed that the gut microbiota absence was associated with reduced neuroinflammation, alleviated neurological dysfunction, and mitigated gut barrier dysfunction post-ICH. In contrast, recolonization of microbiota from ICH-induced SPF mice by transplantation of fecal microbiota (FMT) exacerbated brain injury and gut impairment post-ICH. Additionally, microglia with transcriptional changes mediated the protective effects of gut microbiota absence on brain injury, with Apoe emerging as a hub gene. Subsequently, Apoe deficiency in peri-hematomal microglia was associated with improved brain injury. Finally, we revealed that gut microbiota influence brain injury and gut impairment via gut-derived short-chain fatty acids (SCFA).

Project description:<p>Radiation-induced lung injury (RILI) is a major complication of thoracic radiotherapy. A previous study has indicated an association between berberine (BBR) and reduced incidence of RILI. However, the underlying mechanisms remain unknown. Here we validated the radioprotective role of BBR in mouse model, and we found that this effect was due to gut microbiota modulation as evidenced by microbiota depletion and fecal microbiota transplantation. Specifically, BBR treatment enriched the abundance of Akkermansia muciniphila in gut and its metabolite, inosine (INO). INO exerted protective effects against RILI via epigenetic regulation of NAV3 through H3K27me3 modification. Our findings suggest the potential of BBR in developing therapeutic strategies for RILI and provides insights into its radioprotection mechanism. Additionally, INO could serve as a complementary approach to enhance radioprotection in RILI.</p>

Project description:The aim of this project was to explore the role of gut microbiota in the development of small intestine. The gut microbiota from different groups was used to treat the mice for 1 or 2 weeks. Then the small intestine samples were collected. The RNA was used for the RNA-seq analysis to search the role of gut microbiota in the development of small intestine. Groups: IMA100 mean gut microbiota from Alginate oligosaccharide 100mg/kg treated mice; IMA10 mean gut microbiota from Alginate oligosaccharide 10mg/kg treated mice; IMC mean gut microbiota from control group mice (dosed with water); Sa mean dosed with saline (no gut microbiota). "1" mean dosed for 1 week, "2" means dosed for 2 weeks.
