Degradation of sucrase-isomaltase in the ileum of jejunum-bypassed rats.
نویسندگان
چکیده
At 3 weeks after jejunal-bypass operation in the rat, the proximal ileum exhibited a greater sucrase specific activity than did sham-operated controls, whereas isomaltase activity was unaffected. Electroimmunoassay of sucrase-isomaltase and a degradation product, isomaltase monomer, revealed an elevated molar ratio of sucrase subunit to isomaltase subunit in operated rats, suggesting a decrease in the extent of degradation of ileal sucrase-isomaltase after the jejunal-bypass operation.

Glucagon-like peptide-2 increases sucrase-isomaltase but not caudal-related homeobox protein-2 gene expression.
To determine the effect of glucagon-like peptide-2 (GLP-2) on sucrase-isomaltase and caudal-related homeobox protein-2 (Cdx-2) gene expression, male Wistar rats were divided into total parenteral nutrition (TPN)-fed and GLP-2-treated, TPN-fed groups. TPN was given via a jugular line, inserted under anesthesia, for 7 days. The treatment group received 40 microg/day of GLP-2 intravenously with th...
متن کاملMucosal function in rat jejunum and ileum is altered by induction of colitis.
Many studies dealing with trinitrobenzene sulfonic acid (TNBS) colitis in rats have been carried out referring only to the colon. In humans, ulcerative colitis (UC) can extend a variable distance into the terminal ileum in a phenomenon known as backwash ileitis (BWI). The aim of this study was therefore to examine the effect of TNBS-induced colitis on different aspects of the rat ileum and jeju...
متن کاملDeterminants of regional sucrase-isomaltase expression in adult rat small intestine.
Sucrase-isomaltase (SI) expression along the longitudinal and vertical axis of the small intestine was studied by sequentially isolating enterocytes from villus to crypt of rat proximal jejunum and distal ileum. Gradients of sucrase activity were observed with greatest activity occurring in jejunal and villus regions. Along the villus-to-crypt axis, gradients of SI mRNA abundance corresponded w...
متن کاملInduction of histone acetylation on the sucrase-isomaltase gene in the postnatal rat jejunum.
The rapid induction of the sucrase-isomaltase (SI) gene in rat jejunum from the onset to final period of weaning was associated with increases of the acetylation of histones H3 and H4 on the promoter/transcriptional region of the gene, suggesting that an abrupt jejunal induction of histone acetylation changes on the SI gene during this period may be concerned with the expression of the gene.
متن کاملFetal endoderm primarily holds the temporal and positional information required for mammalian intestinal development
In rodents, the intestinal tract progressively acquires a functional regionalization during postnatal development. Using lactase-phlorizin hydrolase as a marker, we have analyzed in a xenograft model the ontogenic potencies of fetal rat intestinal segments taken prior to endoderm cytodifferentiation. Segments from the presumptive proximal jejunum and distal ileum grafted in nude mice developed ...
