Gene expression profiles in human duodenal organoid-derived monolayer

ABSTRACT: The human small intestine is the key organ for absorption, metabolism, and excretion of orally administered drugs. To preclinically predict these reactions in drug discovery research, a cell model that can precisely recapitulate the in vivo human intestinal monolayer is desired. Here, we developed a monolayer platform using human biopsy-derived duodenal organoids for application to pharmacokinetic studies. The human duodenal organoid-derived monolayer was prepared by a simple method in 3–8 days. It consisted of polarized absorptive cells and had a barrier function. It showed much higher cytochrome P450 (CYP) 3A4 and carboxylesterase (CES) 2 activities than Caco-2 cells. It also showed efflux activity of P-glycoprotein (P-gp) and inducibility of CYP3A4. Finally, its gene expression profile was closer to the adult human duodenum, compared to the profile of Caco-2 cells. Based on these findings, this monolayer assay system using biopsy-derived human intestinal organoids is likely to be widely adopted.

Duodenal-derived organoids from MASH patients exhibit altered digestive homeostasis.

Project description:Metabolic dysfunction-associated steatohepatitis (MASH) is a progressive disease linked to conditions like fibrosis, cirrhosis, and liver cancer, often resulting in higher mortality rates, primarily due to cardiovascular events. While MASH is closely tied to metabolic syndrome, recent research underscores the importance of the gut-liver axis in its pathogenesis, an aspect less explored in human studies. To address this gap, duodenal epithelial organoids were generated from both MASH and healthy (controls) subjects. Organoid formation efficiency was similar between controls derived epithelial organoids (CDEOs) and MASH derived epithelial organoids (MDEOs) groups. Variability in growth patterns was observed, with MDEOs frequently exhibiting cystic spheroid morphology. MASH-derived organoids displayed altered homeostasis and digestive potential in the duodenal epithelium. Despite potential lineage bias, MDEOs retained their lipid metabolic capacity, possibly mediated by lipid oxidation in stem/progenitor cells. Notably, cell adhesion components were misexpressed in MASH-derived organoids, indicating significant intrinsic alterations in cell-cell adhesion potential compared to controls. However, MDEOs maintained transepithelial electric resistance and leak pathway integrity, indicating that the intestinal epithelial barrier remained functionally intact in MDEOs under tested conditions. This study sheds light on the intricate dynamics of duodenal epithelial alterations in MASH, highlighting potential therapeutic avenues for restoring intestinal homeostasis.

Hepatocytes differentiate into intestinal epithelial cells through a hybrid epithelial/mesenchymal cell state in culture II

Project description:We found that hepatocytes isolated from adult mouse livers can dedifferentiate into progenitor-like cells and exhibit a hybrid epithelial/mesenchymal phenotype in monolayer culture. dediHeps can re-differentiate into mature hepatocytes by forming aggregates and fetal intestinal progenitor cells (FIPCs) by forming organoids in three-dimensional culture. We conducted RNA-seq analyses to investigate the characteristincs of hepatocytes, dediHeps, dediHep aggregates, dediHep derived spherical organoids, dediHep derived budding organoids, FIPC derived spherical organoids, intestinal stem cell (ISC) derived budding organoids, and CLiP cells (Katsuda, 2016).

Gene expression data of 2D duodenum organoids with or without continuous flow

Project description:We developed a monolayer culture system for small intestinal organoids, and then placed the culture plate on a rotator to generate a constant flow in the overlay medium. This mechanical stimulation facilitated the formation of villus-like structures from the monolayer of small intestinal organoids.

HIF2 regulates intestinal Wnt5a expression

Project description:Radiation therapy for abdominal tumors is challenging because the small intestine is exquisitely radiosensitive. Unfortunately, there are no FDA-approved therapies to prevent or mitigate GI radiotoxicity. The EGLN protein family are oxygen sensors that regulate cell survival and metabolism through the degradation of hypoxia-inducible factors (HIFs). Our group has previously shown that stabilization of HIF2 through genetic deletion or pharmacologic inhibition of the EGLNs mitigates and protects against GI radiotoxicity in mice by improving intestinal crypt stem cell survival. Here we aimed to elucidate the molecular mechanisms by which HIF2 confers GI radioprotection. We developed duodenal organoids from mice, transiently overexpressed non-degradable HIF2, and performed bulk RNA sequencing. Interestingly, HIF2 upregulated known radiation modulators and genes involved in GI homeostasis, including Wnt5a. Non-canonical Wnt5a signaling has been shown by other groups to improve intestinal crypt regeneration in response to injury. Here we show that HIF2 drives Wnt5a expression in multiple duodenal organoid models. Luciferase reporter assays performed in human cells showed that HIF2 directly activates the WNT5A promoter via a hypoxia response element. We then evaluated crypt regeneration using spheroid formation assays. Duodenal organoids that were pre-treated with recombinant Wnt5a had a higher cryptogenic capacity after irradiation, compared to vehicle-treated organoids. Conversely, we found that Wnt5a knockout decreased the cryptogenic potential of intestinal stem cells following irradiation. Treatment with recombinant Wnt5a prior to irradiation rescued the cryptogenic capacity of Wnt5a knockout organoids, indicating that Wnt5a is necessary and sufficient for duodenal radioprotection. Taken together, our results.txt suggest that HIF2 radioprotects the GI tract by inducing Wnt5a expression.

Microfluidic Device Facilitates In Vitro Modeling of Human Neonatal Necrotizing Enterocolitis-on-a-Chip

Project description:Necrotizing enterocolitis is an intestinal disease induces rapid destruction of the epithelial monolayer of the neonatal intestine. Clinically relevant models of this disease are lacking. Using our novel microfluidic model of necrotizing enterocolitis, we characterized the response of intestinal epithelial cell-derived organoids to intestinal bacteria isolated from a neonate with fatal NEC. We subsequently used RNA-sequencing to determine the gene expression profile of these cells after 24 or 72 hours of incubation.
