A simple, reliable, and user friendly system was established to cultivate Caco-2 cell monolayer for epithelial transport studies. After an initial growth period of 1 week in a CO(2) incubator, Caco-2 cells were cultivated in an automated continuous perfusion system (Minucells and Minutissue, Germany). Medium was constantly renewed at the apical and basal side of the monolayers, which resulted i...
Human colon carcinoma Caco-2 cell monolayers undergo conversion into cells that share morphological and functional features of M cells when allowed to interact with B lymphocytes. A lymphotropic (X4) HIV-1 strain crosses M cell monolayers and infects underlying CD4(+) target cells. Transport requires both lactosyl cerebroside and CXCR4 receptors, which are expressed on the apical surface of Cac...
This study investigated the effects of racemic methadone (MET) on P-glycoprotein (P-gp) activity in cell culture. MET showed no differential rates of passage between the basolateral to apical (B to A) and apical to basolateral (A to B) direction across Caco-2 cell monolayers in a transwell system. MET transport in either direction was not importantly influenced by the P-gp inhibitor verapamil. ...
BACKGROUND An in vitro digestion and Caco-2 cell model may predict iron bioavailability to humans; however, direct comparisons are lacking. OBJECTIVE The objective was to test the differences in iron bioavailability between 2 maize varieties and 2 bean varieties (white beans and colored beans) by comparing human, Caco-2, and algorithm results. DESIGN Two randomized, 2 x 2 factorial experime...
Yoo BK, Yanda MK, No YR, Yun CC. Human intestinal epithelial cell line SK-CO15 is a new model system to study Na /H exchanger 3. Am J Physiol Gastrointest Liver Physiol 303: G180–G188, 2012. First published May 2, 2012; doi:10.1152/ajpgi.00069.2012.—The Caco-2 cell line represents absorptive polarized intestinal epithelial cells that express multiple forms of Na /H exchanger (NHE) in their plas...
BACKGROUND Quercetin and quercetin glycosides are widely consumed flavonoids found in many fruits and vegetables. These compounds have a wide range of potential health benefits, and understanding the bioavailability of flavonoids from foods is becoming increasingly important. METHODS This study combined an in vitro digestion, a lactase treatment and the Caco-2 cell model to examine quercetin ...
BACKGROUND & AIMS The endocannabinoids anandamide and 2-arachidonoylglycerol (2-AG) inhibit cancer cell proliferation by acting at cannabinoid receptors (CBRs). We studied (1). the levels of endocannabinoids, cannabinoid CB(1) and CB(2) receptors, and fatty acid amide hydrolase (FAAH, which catalyzes endocannabinoid hydrolysis) in colorectal carcinomas (CRC), adenomatous polyps, and neighboring...
The uptake and transport of 9-nitrocamptothecin (9-NC), a potent anticancer agent, across Caco-2 cell monolayers was studied as a free and PLGA nanoparticle loaded drug. Different sizes (110 to 950 nm) of 9-nitrocamptothecin nanoparticles using poly (lactic-glycolic acid) were prepared by via the nanoprecipitation method. The transport of nanoparticles across the Caco-2 cell monolayer as a func...
κ-carrageenan (κ-CGN) is an important food additive that has been demonstrated to induce colitis in animal models. In the present study, the effects of κ-CGN were assessed using an in vitro co-culture system that contained intestinal epithelial Caco-2 cells and activated macrophage-like THP-1 cells. The results demonstrated that in single cultures of Caco-2 and THP-1 cells treated with κ-CGN, t...
Organic cation/carnitine transporters (OCT/N) mediate uptake of positively charged molecules. Their role in lung epithelium; however, is not well understood. OCT/N expression and activity was studied in cell lines of human alveolar (A549), bronchial (16HBE14o- and Calu-3) and intestinal (Caco-2) epithelium. Protein levels were largely comparable for all OCT/Ns in the respiratory epithelial cell...
