ISSN: 1432-2013Keywords: H+/Dipeptide transport ; PepT1 ; mRNA ; Enterocytes ; In situ hybridizationSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract In order to examine the intestinal expression of the recently cloned H+/di-tripeptide transporter (PepT1), oligonucleotide probes were synthesized and their specificity confirmed by Northern blot analysis of rabbit jejunal RNA. In situ hybridization studies, using these probes, show that PepT1 is expressed all along the small intestine and at a very much reduced level in the colon. In contrast, PepT1 mRNA was not detected in the stomach, sacculus rotundus or caecum. Microscopic examination of tissue sections showed PepT1 expression to be restricted to intestinal epithelium with no detectable expression in the lamina propria, muscularis mucosae, muscularis or serosa. The accumulation of PepT1 mRNA along the crypt-villus axis was also investigated. In all regions of the small intestine (in duodenum, jejunum and ileum), PepT1 mRNA was undetectable in deeper epithelial cells of the crypts. Expression was first detectable at or near the crypt-villus junction, the amount of PepT1 mRNA increasing rapidly in the lower villus to a maximum approximately 100–200 μm from this point. Along the length of the small intestine PepT1 mRNA was most abundant in duodenal and jejunal enterocytes, with lower levels in the ileal epithelium. PepT1 expression is greatly depressed in the follicle-associated epithelium of the Peyer's patch relative to both interfollicular and adjacent “normal” villi. These data are discussed in the context of the known physiological role of PepT1 in the gastrointestinal tract.Type of Medium: Electronic ResourceURL: -

The present study has used a combination of quantitative in situ hybridisation, immunohistochemistry and enzyme cytochemistry to examine epithelial cell differentiation in rabbit small intestine. We have measured and compared the levels of mRNA and enzyme activity of the enterocyte brush border markers alkaline phosphatase, aminopeptidase N and lactase in normal villus epithelia and in epithelial cells exposed directly to the Peyer's patch immune environment. All three genes appeared to be expressed in parallel, but in each epithelial population examined, the pattern of gene expression was different. The level of these mRNAs was markedly reduced in Peyer's patch-associated epithelia, this being most pronounced in the follicle-associated epithelium, compared with normal villi. The activities of alkaline phosphatase and aminopeptidase N approximated the expression of their genes, whereas additional post-transcriptional events were shown to clearly contribute to the level of lactase activity in these tissues. These findings demonstrate that the reduced brush border hydrolase activity in Peyer's patch tissue that has been observed previously, is due to a down-regulation of epithelial gene expression in this location. These observations have been used to discuss epithelial differentiation in Peyer's patch tissue and the possible role of local immune factors in regulating such events.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-2013Keywords: Differentiation ; Brush border ; Crypt ; Villus ; Absorption ; Digestion ; Glucose transportSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The enterocyte undergoes sequential changes in its structure and function as it migrates rapidly from the small intestinal crypts to the villus tip. The mechanisms by which these changes are regulated “in tune” with ontogenic and dietary changes in the luminal environment are currently under investigation. This study has employed oligonucleotide probes to follow the expression of the lactase-phlorizin hydrolase (LPH) and Na+-glucose cotransporter (SGLT1) genes in rabbit small intestine using quantitative in situ hybridisation histochemistry. The profiles of LPH mRNA and SGLT1 mRNA accumulation along the crypt-villus axis were found to be very similar. Although mRNA was undetectable in the crypt, LPH and SGLT1 mRNA levels rose rapidly at the crypt-villus junction, reaching a maximum between 210 μm and 330 μm above this point. Further up the villus the level of mRNAs declined. SGLT1 mRNA was present in all small intestinal segments (duodenum, jejunum and ileum), whereas LPH mRNA was absent from the ileum. LPH activity rose and fell in conjunction with mRNA, but SGLT1 activity was greatest at the villus tip where mRNA levels were considerably reduced. These data have been used to discuss the genetic regulation of enterocyte differentiation and function.Type of Medium: Electronic ResourceURL:
