there is a great concern about the effect of propoxur, as one of the more common n-methyl carbamate pesticides, on human health due to its extensive use in agricultural and non-agricultural applications. caco-2 cells became resistant to propoxur, and the resistance was confirmed through mtt assay. then the cell membrane integrity and p-glycoprotein expression were measured by ldh assay and west...
the cytotoxic activity of natural killer cells is usually tested by radioactive assay csi cr release assay), which detects the release of cytoplasmic contents after plasma membrane disintegration of dying cells. in contrast to this indirect evaluation of cytotoxicity, the assessment of cell damage by flow cytometry aims to provide a more exact characterization of the death pathway via detection...
The present study aimed at exploring the potential of the P-glycoprotein (P-gp) transporters as a barrier to the repaglinide (REG) epithelial permeability. In-vitro intestinal absorption models, the everted gut sac, and Caco-2 cell line, were used to study the possible role of P-gp in intestinal transport of REG. In the everted gut sacs, apparent permeability coefficients showed cargo concentra...
Introduction: Polyphenolic compounds have anti proliferative and induced apoptotic features on cancer cells. p-Coumaric acid can be abundantly found in fruits, vegetables, plant production and honey. . Breast cancer is the most frequently diagnosed cancer among women in the world. This study aimed to investigate the effect and mechanism of p- coumaric acid on apoptosis of MCF-7 breast can...
p-nonylphenol (p-np) as a non ionic surfactant is used in many industries such as pesticides, cosmetics,detergents and so on. our previous study showed that the p-np causes reduction in viability of the rats bonemarrow mesenchymal stem cells (mscs). the aim of the present study was to investigate the mechanism of the cell death due to p-np exposure. the cells, after 3rd passage were treated wit...
The memory of somatic cell gene expression is reset in the germline in a process that is accompanied by dramatic changes in chromatin modifications. In this issue, Katz et al. (2009) show that the histone demethylase Lsd1/Spr-5 may participate in this resetting process in the worm, thereby preventing a decline in germ cell epigenetic stability and viability over ensuing generations.
