Quantitative LC-MS/MS Proteomics of paediatric biliary atresia human liver microsomes

Project description:We report label-free quantification of xenobiotic metabolizing enzymes (XME), transporters, redox enzymes, proteases and nucleases in 25 human liver microsomal samples, taken from patients with biliary atresia. Nearly 3500 proteins were identified and quantified. These data can be used in physiologically based pharmacokinetic models to predict appropriate drug doses drugs used in biliary atresia patients.

Comprehensive gene expression profile of human livers from patients with biliary atresia at the time of diagnosis and the corresponding disease and normal controls

Project description:Liver biopsy samples were obtained from 64 infants with biliary atresia at the time of intraoperative cholangiogram. Liver biopsy samples were obtained from 14 age-matched infants with other causes of intrahepatic cholestasis, and from 7 deceased-donor children. GeneChip® Human Gene 1.0 ST Array (Affymetrix, CA) were used to screen mRNAs whose expression was specifically regulated in the livers from patients with biliary atresia. Gene expression profiling: Liver biopsy samples obtained from infantas with other causes of intrahepatic cholestasis were served as diseased control. Liver tissue obtained from deceased-donor children were served as normal control. A molecular signataure of biliary atresia at the time of diagnosis was identified by comparing hepatic gene expression profile from biliary atresia to those from diseased and normal controls. This dataset is part of the TransQST collection.

Biliary organoids uncover delayed epithelial development and barrier function in biliary atresia.

Project description:Background: RNASeq was performed on organoids derived from livers of normal healthy donors and patients with biliary atresia to characterize transcriptomic signatures. Methods: Organoids generated from livers of normal healthy donors and patients with biliary atresia were cultured either in expansion (undifferentiated: 3 NCOs and 11 BACOs) or differentiation medium (differentiated: 3 BACOs). Liver tissues obtained from deceased-donor subjects served as normal controls (N=3). Total RNA was isolated from organoids and liver biopsy tissue specimens. Results: Organoids from patients with biliary atresia showed abnormal cell polarity, loss of tight junctions, increased permeability and decreased expression of genes related to epidermal growth factor (EGF)- and fibroblast growth factor 2 (FGF2)-signaling. When treated with EGF+FGF2, biliary atresia organoids expressed differentiation and functional markers with restored cell polarity. Conclusion: Organoids from biliary atresia are viable and have evidence of halted epithelial development. The induction of developmental markers, improved cell‐cell junction, and decreased epithelial permeability by EGF and FGF2 identifies potential strategies to promote epithelial maturation and function.

Gene expression profile of human liver MAIT cells from patients with biliary atresia

Project description:To investigate gene expression profile of human liver MAIT cells from patients with biliary atresia, we isolated human liver MAIT cells from liver tissues of patients with biliary atresia and from adjacent non-tumor liver tissues of hepatoblastoma patients (as control) at the time of diagnosis, and subjected for bulk RNA sequencing.

Aged gut microbiota contributes to systemical inflammaging after transfer to germ-free mice

Project description:Advanced age is associated with chronic low-grade inflammation, which is usually referred to as inflammaging. Elderly are also known to have an altered gut microbiota composition. However, whether inflammaging is a cause or consequence of an altered gut microbiota composition is not clear. In this study gut microbiota from young or old conventional mice was transferred to young germ-free mice. Four weeks after gut microbiota transfer immune cell populations in spleen, Peyer’s patches, and mesenteric lymph nodes from conventionalized germ-free mice were analyzed by flow cytometry. In addition, whole-genome gene expression in the ileum was analyzed by microarray. Gut microbiota composition of donor and recipient mice was analyzed with 16S rDNA sequencing. Here we show by transferring aged microbiota to young germ-free mice that certain bacterial species within the aged microbiota promote inflammaging. This effect was associated with lower levels of Akkermansia and higher levels of TM7 bacteria and Proteobacteria in the aged microbiota after transfer. The aged microbiota promoted inflammation in the small intestine in the germ-free mice and enhanced leakage of inflammatory bacterial components into the circulation was observed. Moreover, the aged microbiota promoted increased T cell activation in the systemic compartment. In conclusion, these data indicate that the gut microbiota from old mice contributes to inflammaging after transfer to young germ-free mice.

Analysis of gut microbiota by pyrosequencing of 16S rRNA gene in F344 rats

Project description:Chronic acid suppression by proton pump inhibitor (PPI) has been hypothesized to alter the gut microbiota via a change in intestinal pH. To evaluate the changes in gut microbiota composition by long-term PPI treatment. Twenty-four week old F344 rats were fed with (n = 5) or without (n = 6) lansoprazole (PPI) for 50 weeks. Then, profiles of luminal microbiota in the terminal ileum were analyzed. Pyrosequencing for 16S rRNA gene was performed by genome sequencer FLX (454 Life Sciences/Roche) and analyzed by metagenomic bioinformatics.
