Synthesis of Membrane Glycoproteins in Rat Small-Intestinal Villus Cells
The biogenesis of plasmalemma glycoproteins of rat small-intestinal villus cells was studied by following the incorporation of L-[1,5,6-3H]fucose, given intraperitoneally with and without chase, into Golgi, lateral basal and microvillus membranes. Each membrane fraction showed distinct kinetics of incorporation of labelled fucose and was differently affected by the chase, which produced a much ...
متن کاملSmall Intestinal Lymphangioma Invagination
Nous presentons le cas d'un jeune homme de 25 ans qui s·est presente a notre service avec le symptomatologie de !'abdomen aigue. Les investigations preoperatoire ne montrent pas J'etiologie de son etat. A.laparotomie on trouve une tumeur polypeuse (Lymphangiome) de la muqueuse jejunale causant l'invagination et la necrose de la paroi intestinale.
متن کاملHuman cell models to study small intestinal functions: recapitulation of the crypt-villus axis.
The intestinal epithelium is continuously and rapidly renewed by a process involving cell generation, migration, and differentiation, from the stem cell population located at the bottom of the crypt to the extrusion of the terminally differentiated cells at the tip of the villus. Because of the lack of normal human intestinal cell models, most of our knowledge about the regulation of human inte...
متن کاملA low-temperature method for the isolation of small-intestinal epithelium along the crypt-villus axis.
A variety of enzymic and non-enzymic methods to isolate epithelium from the small intestine have been previously published. Sequential fractionation of cells from the villus to the crypt has been reported in some of these papers, which allows the comparative study of terminally differentiated and proliferative cell phenotypes. However, these methods often involve the incubation of tissues at 37...
متن کاملIdentification and characterization of rabbit small intestinal villus cell brush border membrane Na-glutamine cotransporter.
Glutamine, the primary metabolic fuel for the mammalian small intestinal enterocytes, is primarily assimilated by Na-amino acid cotransporters. Although Na-solute cotransport has been shown to exist in the brush border membrane (BBM) of the absorptive villus cells, the identity of Na-glutamine cotransport in rabbit small intestinal villus cells was unknown. Na-dependent glutamine uptake is pres...
