Transepithelial Taurine Transport in Caco-2 Cell Monolayers

Journal of Membrane Biology, 2005
Here we characterized transepithelial taurine transport in monolayers of cultured human intestinal Caco-2 cells by analyzing kinetic apical and basolateral uptake and efflux parameters. Basolateral uptake was Na(+)- and Cl(-)- dependent and was inhibited by beta-amino acids.

Campylobacter jejuni motility and invasion of Caco-2 cells

Infection and Immunity, 1995
We investigated the influence of motility on Campylobacter jejuni binding and invasion of Caco-2 cells. C. jejuni was motile in soft agar at basic (pH 8.5) and neutral pH values representative of the intestinal environment. However, C. jejuni was immobilized at pH 5.0. The inability of C.

Toxic and biochemical effects of zinc in Caco-2 cells

Journal of Inorganic Biochemistry, 2003
Zinc (in relatively high concentrations) can be toxic to intestinal cells. The aim of the present study was to quanitfy cellular injury in preconfluent, colonic cancerous cells and in postconfluent, differentiating human intestinal Caco-2 cells. Cellular damage was measured by using cell proliferation, lactate dehydrogenase (LDH)-release, and apoptosis

Poliovirus infection induces apoptosis in CaCo-2 cells

Journal of Medical Virology, 1999
The effects of poliovirus infection in CaCo-2 cells, a human enterocyte-like cell line are described. Infected cells were examined by a combination of techniques, including optical and electron microscopy, cytofluorimetric analysis of DNA content, and DNA agarose gel electrophoresis. Results obtained by the different experimental approaches demonstrate

Putrescine transport in differentiated Caco-2 cells.

Gastroenterologie clinique et biologique, 1996
To evaluate the putative importance of digestive luminal polyamines, we investigated the role of oxidation in putrescine uptake and transport in differentiated Caco-2 cells grown in monolayer.Our results confirm a putrescine uptake system located both at the apical and basolateral cell membrane. Putrescine is efficiently transported and excreted in the

Esterification of xanthophylls by human intestinal Caco-2 cells

Archives of Biochemistry and Biophysics, 2009
We recently found that peridinin, which is uniquely present in dinoflagellates, reduced cell viability by inducing apoptosis in human colon cancer cells. Peridinin is also found in edible clams and oysters because the major food sources of those shellfish are phytoplanktons such as dinoflagellates.

Transport and metabolism of (±)-praeruptorin A in Caco-2 cell monolayers

Xenobiotica, 2010
(±)-Praeruptorin A (dl-PA) is one of the main pyranocoumarins of Peucedani Radix and the chemical marker for quality control of the herb in China. This study investigated the transport and metabolism of dl-PA, for the first time, in Caco-2 cell monolayers.

2-Deoxyglucose transport and metabolism in Caco-2 cells

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1996
We investigated the kinetics of 2-deoxy-D-glucose (DG) uptake and metabolism in Caco-2 cells, because this human cell line may represent a valid enterocyte model to assess the dynamics between sugar transport and metabolism and hence to obtain insights into the factors involved during the intracellular phase of glucose absorption.

Novel Choline Transport Characteristics in Caco-2 Cells

Drug Development and Industrial Pharmacy, 2002
Choline transport is characterized by sodium-dependent high-affinity, sodium-independent low-affinity, and sodium-independent blood-brain barrier transport mechanisms. Each defined mechanism has specific characteristics with regard to affinity for choline, transport capacity, and inhibition by hemicholinium.
