The integrity of the intestinal epithelium is crucial for the barrier function of the gut. Replenishment of the gut epithelium by intestinal stem cells contributes to gut homeostasis, but how the differentiated enterocytes are protected against stressors is less well understood. Here we use the Drosophila larval hindgut as a model system in which damaged enterocytes are not replaced by stem cel...

The butyrate-producing Megasphaera spp. predominate in the pig hindgut and may play important roles in gut health. Moreover, one Megasphaera isolate has been reported to produce the boar taint compound, skatole. Here, we provide a 2.58-Mbp draft genome of a pig hindgut isolate, Megasphaera sp. DJF_B143, unable to produce skatole.

Steel factor is an essential survival and proliferation factor for primordial germ cells (PGCs) during their migration in the early mouse embryo. PGCs arise during gastrulation, and migrate into the posterior endoderm that becomes the hindgut. Previous reports have suggested that PGCs become dependent on Steel factor when they colonize the hindgut. However, in the absence of a good marker for l...

Capniomyces stellatus is a host-specific endosymbiotic fungus, living in the hindgut of stoneflies (especially in Allocapnia). Here, we present the first draft genome sequence of the fungus, as well as the ab initio gene prediction and function analyses, which will facilitate the study and comparative analyses of insect-associated fungi.

Complete hindgut duplication is a rare and intriguing entity, often coupled with genitourinary abnormalities and neural tube defects. The diagnosis demands a thorough clinical exam and radiological workup. Timely recognition and expeditious treatment of these patients can lead to a better quality of life. We present a case of a 10-month-old female with complete hindgut duplication and associate...

Acetate disappearance from the loops of the hindgut in the rabbit was evaluated by measuring variations in the concentration of acetate in caecocolonic loops and differences in the arterial and venous plasma. In vivo metabolism in gut and liver tissues was studied after introduction of (1-'4C) acetate into caecocolonic loops. The rate of disappearance from the loops was quantitatively significa...

During Drosophila embryogenesis, the development of the midgut endoderm depends on interactions with the overlying visceral mesoderm. Here we show that the development of the hindgut also depends on cellular interactions, in this case between the inner ectoderm and outer visceral mesoderm. In this section of the gut, the ectoderm is essential for the proper specification and differentiation of ...

To investigate the ecological mechanisms governing the community structure of the gut microbial ecosystem, we have attempted to simulate the rat gut ecosystem in vitro using a two-stage continuous culture. Extensive sampling of the rat hindgut has established a set of criteria with which the in vitro system may be compared. This paper discusses one of the criteria, the community composition and...

PURPOSE It is widely accepted that lipopolysaccharide and volatile fatty acids (VFA) accumulate in the digestive tract of ruminants fed diets containing high portions of grain. Compared to the ruminal epithelium, the hindgut epithelium is composed of a monolayer structure that is more "leaky" for lipopolysaccharide and susceptible to organic acid-induced damage. The aim of this study was to inv...
