Clonal analysis of sucrase-isomaltase expression in the human colon adenocarcinoma Caco-2 cells.
To investigate the biosynthetic basis for the mosaic expression of brush border enzymes in confluent Caco-2 cells, a human colon carcinoma cell line exhibiting characteristics of adult small intestinal enterocytes, we have obtained a series of clones differing markedly in their growth rates, amounts of transforming growth factor-alpha/epidermal growth factor-like activity released into the cult...
متن کاملFunction and expression of multidrug resistance-associated protein family in human colon adenocarcinoma cells (Caco-2).
Several organic anions are actively extruded from intestinal epithelial cells into the lumen and vascular sides. To examine the role of the multidrug resistance-associated protein (MRP) family in the intestinal efflux of organic anions, the function and expression of these proteins were investigated with Caco-2, a human adenocarcinoma cell line that retains many of the characteristics of normal...
متن کاملGlutathione-conjugate transport by human colon adenocarcinoma cells (Caco-2 cells).
The secretion of a glutathione-S-conjugate, dinitrophenyl-glutathione (GS-DNP) was studied in the Caco-2 cells, a cultured human colonic adenocarcinoma cell line with many of the characteristics of enterocytes. The labelled glutathione conjugate was generated within the cell by incubation with 14C-labelled 1-chloro-2,4-dinitrobenzene (CDNB). This compound is hydrophobic and enters the cell by s...
متن کاملThe clinical consequences of sucrase-isomaltase deficiency
Primary sucrase-isomaltase deficiency, originally thought to be a homozygous recessive disorder, has been found to have numerous genetic variants that alone or in combination (compound heterozygosity) express varying degrees of clinical illness, most commonly causing chronic diarrhea, abdominal pain, and bloating. These symptoms are also present with secondary sucrase-isomaltase deficiency. Rec...
متن کاملA and H blood group antigens as markers of sucrase-isomaltase from the enterocyte-like differentiated human colon carcinoma cell lines HT-29 and Caco-2.
The purpose of this work was to investigate whether sucrase-isomaltase from enterocyte-like differentiated human colon carcinoma cell lines carries blood group antigens of the ABH system. Six cultured lines of blood group A (HT-29, SW-480, Co-115) or O phenotype (Caco-2, HRT-18, HCT-8R) were studied. Only HT-29 cells grown in the absence of glucose (HT-29 Glc-) and Caco-2 cells express an enter...
