Objective(s): Chemotherapies used to treat colon cancer might often fail due to the emergence of chemoresistance and side effects. Escherichia coli Nissle 1917 (EcN) is a beneficial probiotic, whose molecular mechanisms in the prevention of colon cancer are yet to be fully understood. The present study assessed the anti-cancer effects of EcN treatments in human colorec...

1. HT-29 M6 cells are a subpopulation of HT-29 cells that, contrarily to the parental cells, establish tight cell contacts and differentiate. Cell-to-cell contacts in HT-29 M6 cells are also regulated by protein kinase C; addition of the phorbol ester phorbol 12-myristate 13-acetate (PMA) decreases the homotypic contacts of these cells. We show here that HT-29 cells or HT-29 M6 cells treated wi...

a multiple colorimetric assay has been introduced to evaluate the proliferation and determination of survival fraction (sf) of irradiated cells. the estimation of sf based on the cell‑growth curve information is the major advantage of this assay. in this study, the utility of multiple‑mts assay for the sf estimation of irradiated ht‑29 colon cancer cells, which were plated before irradiation, w...

The use of nanoparticles (NPs) has been extended to many fields such as agriculture, food industry, medicine and biotechnological fields. Thereby, human exposure to NPs consequently increases. Therefore, there is a concern about the potential biological effects and toxicity of NPs for humans and the environment. This study aimed to investigate the cytotoxicity effects of magnesium oxide (MgO) a...
