"PROJECT":{"PROJECT_TITLE":"Enteric microbiota and liver metabolomics during the postnatal period","PROJECT_SUMMARY":"Following birth, the neonatal intestine is exposed to maternal and environmental bacteria that successively form a dense and highly dynamic intestinal microbiota. Whereas the effect of exogenous factors has been extensively investigated, endogenous, host-mediated mechanisms have remained largely unexplored. Concomitantly with microbial colonization, the liver undergoes functional transition from a hematopoietic organ to a central organ of metabolic regulation and immune surveillance. The aim of the present study was to analyze the influence of the developing hepatic function and liver metabolism on the early intestinal microbiota. Using metabolomic and microbial profiling in combination with multivariate analysis we characterized the colonization dynamics and liver metabolism in the murine gastrointestinal tract (n=6-10 per age group). We observed major age-dependent microbial and metabolic changes and identified bile acids as potent drivers of the early intestinal microbiota maturation. Consistently, oral administration of tauro-cholic acid or β-tauro-murocholic acid to newborn mice (n= 7-14 per group) accelerated postnatal microbiota maturation.","INSTITUTE":"Helmholtz Centre for Environmental Research - UFZ","LAST_NAME":"Haange","FIRST_NAME":"Sven","ADDRESS":"Permoserstrasse 1, Leipzig, Saxony, 04318, Germany","EMAIL":"sven.haange@ufz.de","PHONE":"0049 341 2351099"},

"TREATMENT":{"TREATMENT_SUMMARY":"All C57BL6J wildtype mice were bred locally and held under specific pathogen-free conditions at the Institute of Laboratory Animal Science at RWTH Aachen University Hospital.

Per mg of sample 5µL of extracting agent was added. Shake the samples for 10 minutes at 30 Hz in the tissue slicer and centrifuge for 2 minutes at 14000 rpm. The supernatant was used for the targeted analytics. Kit reparation The analysis was performed using the validated MetIDQ p180 Kit and described in Siskos et al. [1]. Data processing was carried out with the provided quantitation method Kit (Biocrates Life Sciences AG, Innsbruck, Austria). 1 Siskos AP, Jain P, Römisch-Margl W, Bennett M, Achaintre D, Asad Y, et al.
