Human cytomegalovirus (CMV) causes severe disease in immunosuppressed patients and notably infects the gastrointestinal tract. To understand the interaction of CMV with intestinal epithelial cells, which are highly susceptible to CMV infection in vivo, we used the intestinal epithelial cell line Caco-2 and demonstrated that CMV enters predominantly through the basolateral surface of polarized C...
Cadmium (Cd) is a widespread environmental toxic contaminant, which causes serious health-related problems. In this study, human intestinal cell line (Caco-2 cells) and normal human liver cell line (HL-7702 cells) were used to investigate the toxicity and bioavailability of Cd to both cell lines and to validate these cell lines as in vitro models for studying Cd accumulation and toxicity in hum...
Pathogenic mechanisms responsible for inflammatory bowel disease (IBD) are poorly understood. In an IBD animal model, the oral administration of polysaccharides such as dextran sulfate sodium (DSS) induces colitis, which exhibit several clinical and histological features for IBD. However, pathogenic factors in the development of colitis remain unclear. Therefore, we investigated possible mechan...
Differentiated human intestinal Caco-2 cells are frequently used in toxicology and pharmacology as in vitro models for studies on intestinal barrier functions. Since several discrepancies exist among the different lines and clones of Caco-2 cells, comparison of the results obtained and optimisation of models for use for regulatory purposes are particularly difficult, especially with respect to ...
background: numerous molecules in papaveraceae family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few cases. objective: numerous molecules in this family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few...
Hu, Chaobin, and David H. Perlmutter. Regulation of a1-antitrypsin gene expression in human intestinal epithelial cell line Caco-2 by HNF-1a and HNF-4. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G1181–G1194, 1999.— There is still relatively limited information about mechanisms of gene expression in enterocytes and mechanisms by which gene expression is regulated during enterocyte di...
Evaluation of Iron Bioavailability in Caco-2 cell Culture Model: Modification of the Original Method
Background and Objectives: In the original in vitro method for evaluation of iron bioavailability using caco-2 cell model, ferritin formation by cells is considered as a functional indicator of both absorption and utilization of iron. However, as iron is measured in the tested material and then ferritin concentration is measured in caco-2 cell lysate, it is almost impossible to have a concrete ...
Ochratoxin A increases permeability through tight junctions by removal of specific claudin isoforms.
On interaction with the intestine, the mycotoxin ochratoxin A is know to cause rapid inflammation, diarrhea, and increased bacterial translocation. All these effects are consistent with a decrease in epithelial barrier function. However, this has not been shown directly. We determined that ochratoxin A is able to reduce the barrier properties of the model intestinal cell line Caco-2. Over 24 h,...
