Bioengineering human mini-intestines with in vivo-like complexity and function

Biological research heavily relies on the use of animal models, which has made it difficult to answer specific questions about human biology and disease. However, with the advent of human organoids - miniature versions of tissues generated in 3D human stem ...

Infection with a small intestinal helminth, Heligmosomoides polygyrus bakeri, consistently alters microbial communities throughout the murine small and large intestine

Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Alexis Rapin, Luc Xavier Marie Lebon, Audrey Geneviève Chuat

Increasing evidence suggests that intestinal helminth infection can alter intestinal microbial communities with important impacts on the mammalian host. However, all of the studies to date utilize different techniques to study the microbiome and access dif ...

The Receptor TGR5 Mediates the Prokinetic Actions of Intestinal Bile Acids and Is Required for Normal Defecation in Mice

Kristina Schoonjans

BACKGROUND & AIMS: Abnormal delivery of bile acids (BAs) to the colon as a result of disease or therapy causes constipation or diarrhea by unknown mechanisms. The G protein-coupled BA receptor TGR5 (or GPBAR1) is expressed by enteric neurons and endocrine ...

Serotonin receptor diversity in the human colon: Expression of serotonin type 3 receptor subunits 5-HT3C, 5-HT3D, and 5-HT3E

Rudolf Hovius

Since the first description of 5-HT3 receptors more than 50 years ago, there has been speculation about the molecular basis of their receptor heterogeneity. We have cloned the genes encoding novel 5-HT3 subunits 5-HT3C, 5-HT3D, and 5-HT3E and have shown th ...

Hox gene function in vertebrate gut morphogenesis: the case of the caecum

Denis Duboule, Jozsef Zakany

The digestive tract is made of different subdivisions with various functions. During embryonic development, the developing intestine expresses combinations of Hox genes along its anterior to posterior axis, suggesting a role for these genes in this regiona ...

Intestinal antiinflammatory effect of 5-aminosalicylic acid is dependent on peroxisome proliferator-activated receptor-gamma

Johan Auwerx, Walter Wahli

5-aminosalicylic acid (5-ASA) is an antiinflammatory drug widely used in the treatment of inflammatory bowel diseases. It is known to inhibit the production of cytokines and inflammatory mediators, but the mechanism underlying the intestinal effects of 5-A ...

Fermentation by gut microbiota cultured in a simulator of the human intestinal microbial ecosystem is improved by supplementing a soygerm powder

Bart Deplancke

An in vitro model, designated the Simulator of the Human Intestinal Microbial Ecosystem (SHIME), was used to study the effect of a soygerm powder rich in beta-glycosidic phytoestrogenic isoflavones on the fermentation pattern of the colon microbiota and to ...

PPARgamma3 mRNA: a distinct PPARgamma mRNA subtype transcribed from an independent promoter

Johan Auwerx

PPARgamma is a member of the peroxisome proliferator activated receptors (PPAR) subfamily of nuclear receptors. So far two PPARgamma isoforms, PPARgamma1 and PPARgamma2, were known in mammals. We describe the structure of a novel human PPARgamma subtype, P ...

Tissue distribution and quantification of the expression of mRNAs of peroxisome proliferator-activated receptors and liver X receptor-alpha in humans: no alteration in adipose tissue of obese and NIDDM patients

Johan Auwerx

Members of the peroxisome proliferator-activated receptor (PPAR) family might be involved in pathologies with altered lipid metabolism. They participate in the control of the expression of genes involved in lipid metabolism and adipocyte differentiation. I ...

Function of posterior HoxD genes in the morphogenesis of the anal sphincter

Denis Duboule, Jozsef Zakany

Vertebrate 5'-located HoxD genes are expressed in the most caudal part of the digestive tract and their potential functions during gut development have been assessed by gene disruptions. We have inserted reporter lacZ sequences within the Hoxd-12 gene and ...
