Both organs are also interconnected through enterohepatic circulation, which imply there are crosstalk through circulating factors such as signaling molecules or metabolites that may affect drug metabolism. Coculture of hepatocytes and intestinal cells have shown to increase hepatic drug metabolism, yet its crosstalk mechanism is still unclear. In this study, we aim to elucidate such crosstalk by coculturing primary human hepatocytes harvested from chimeric mouse (PXB-cells) and iPSc-derived intestinal cells in a microphysiological systems (MPS). Perfusion and direct oxygenation from the MPS were chosen and confirmed to be suitable features that enhanced PXB-cells albumin secretion, cytochrome P450 (CYP) enzymes activity while also maintaining barrier integrity of iPSc-derived intestine cells. Results from RNA-sequencing showed significant upregulation in gene ontology terms related to fatty acids metabolism in PXB-cells. One of such fatty acids, arachidonic acid, enhanced several CYP enzyme activity in similar manner as coculture. From the current evidences, it is speculated that the release of bile acids from PXB-cells acted as stimuli for iPSc-derived intestine cells to release lipoprotein which was ultimately taken by PXB-cells and enhanced CYP activity.<\/jats:p>","DOI":"10.1093\/pnasnexus\/pgae070","type":"journal-article","created":{"date-parts":[[2024,2,9]],"date-time":"2024-02-09T13:02:26Z","timestamp":1707483746000},"source":"Crossref","is-referenced-by-count":24,"title":["Gut\u2013liver microphysiological systems revealed potential crosstalk mechanism modulating drug metabolism"],"prefix":"10.1093","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9449-2197","authenticated-orcid":false,"given":"Dhimas Agung","family":"Kurniawan","sequence":"first","affiliation":[{"name":"Department of Chemical System Engineering, Graduate School of Engineering, University of Tokyo , Tokyo 113-8656 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvia","family":"Leo","sequence":"additional","affiliation":[{"name":"School of Life Science and Technology, Tokyo Institute of Technology , Kanagawa 226-8501 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mutsumi","family":"Inamatsu","sequence":"additional","affiliation":[{"name":"PhoenixBio Co.
