Probiotics have already proven beneficial effects in the treatment of several intestinal infections, but the underlying mechanisms how the probiotics can affect responses of porcine IPEC-J2 enterocytes to oxidative stress remained to be elucidated. The immunmodulatory effect of five bacterial strains (Lactobacillus plantarum 2142, Lactobacillus casei(More)
Necrotic enteritis caused by Clostridium perfringens leads to serious economical losses to the poultry industry. There is a growing need to find effective, nontoxic, antibiotic alternatives to prevent and cure the disease. In our study, the efficacy of protected sodium butyrate at 1.5 g/kg (BP70), a Bacillus amyloliquefaciens spore suspension with 10(9)(More)
Reactive oxygen species are implicated in cell and tissue damage in a number of diseases including acute and chronic inflammation of the gut. Effects of H2O2 exposure on non-carcinogenic porcine epithelial cell line, IPEC-J2 cells cultured on collagen-coated membrane inserts were monitored based on transepithelial electrical resistance (TER) change, extent(More)
Recently, there has been a growing interest to replace antibiotics' administration with the application of probiotics. The aim of our investigations was to reveal the influence of spent culture supernatant of Lactobacillus plantarum 2142 on the response of enterocytes to oxidative stress, and the spent culture supernatant's ability to protect them from(More)
To investigate the role of reactive oxygen species (ROS) induced by butyrate in tumor cells, we compared HT29R, an HT29-derived human colon cancer cell line refractory to butyrate-induced cell differentiation but highly sensitive to cell death, with the differentiation-positive HT29-12 and HT29-21 cell lines (exhibiting low sensitivity to butyrate-induced(More)
