Outline of Final Research Achievements |
This study is being conducted to identify gut microbiota-derived metabolites that stimulate intestinal stem cells. Utilizing a novel assay system targeting R-spondin-LGR4/5/6-ZNRF3/RNF43 axis, we first screened a small-molecule compound library and identified 2 unique compounds that enhance R-spondin activities. This proof-of-concept experiment suggests that this newly established assay is well suited for biochemical purification of bioactive metabolites from crude microbiota-derived extracts. We also conducted comprehensive metabolomic analysis and identified 54 metabolites from fecal extracts of germ-free mice that had received fecal microbiota transplantation (FMT). The biological activities of these metabolites are currently being examined.
