The aim of the present study was to evaluate cytotoxic potential a new complex silver(I) with furosemide (Ag-FSE) over panel tumor and non-tumor human cells, as well its genotoxicological safety. According results obtained, cell line derived from colorectal adenocarcinoma (Caco-2) most sensitive Ag-FSE complex, among cells non-transforming fibroblasts known GM07492A, which stimulated characteri...

background: prostate cancer is one of the leading causes of cancer deaths among men. new gene expressed in prostate (ngep), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. because of its selective expression in prostate cancer cell surface, ngep is a potential immunotherapeutic target. to target the ngep in prostate cancer, it is essential to investigat...

We developed an in vitro screening system for antihyperlipidemic activity by measuring lipoprotein profiles secreted from human intestinal epithelium-like cells from the colon cancer cell line, Caco-2. Sodium (Na) butyrate at 5 mM differentiated Caco-2 cells into intestinal epithelium-like cells and numerous microvilli on the apical side of cells were observed under transmission electron micros...

During the differentiation of human enterocytes, the secretion of apolipoprotein B is switched from the apoB-100 form seen almost exclusively in fetal cells to the apoB-48 form seen almost exclusively in adult cells. This switch is accomplished by the post-transcriptional editing of the messenger RNA for apoB-100. We report that a similar switch occurs during the differentiation of the human co...

The Caco-2 cell line represents absorptive polarized intestinal epithelial cells that express multiple forms of Na(+)/H(+) exchanger (NHE) in their plasma membranes. Caco-2 cells express the major apical NHE isoform NHE3, but low NHE3 expression together with inefficient transfection often hamper intended studies. In this study, we examined whether SK-CO15 cells could be used to study NHE3 regu...

Several in vitro assays have been developed to evaluate the gastrointestinal absorption of compounds. Our aim was to compare 3 of these methods: 1) the bio-mimetic artificial membrane permeability assay (BAMPA) method, which offers a high-throughput, noncellular approach to the measurement of passive transport; 2) the traditional Caco-2 cell assay, the use of which as a high-throughput tool is ...

synthesized sucrase-isomaltase with the basolateral membrane fraction may have been due to a co-purification of basolateral membranes with transport vesicles for which no marker proteins are known. The differentiated colon carcinoma cell line Caco 2 represents a promising cell culture model for studying molecular mechanisms underlying intracellular membrane traffic and the biogenesis of surface...

Di- and tripeptides, as well as peptidomimetic drugs such as cephalexin (CFX), are absorbed by enterocytes via the oligopeptide transporter PepT1. We recently showed that the alpha(2)-adrenergic agonist clonidine increases CFX absorption in anaesthetized rats. Herein, we investigated whether alpha(2)-adrenergic receptors can directly affect PepT1 activity in a clone of the differentiated human ...
