Effects of digested onion extracts on intestinal gene expression using rat intestine slices


ABSTRACT: Rat small intestine precision cut slices were exposed for 6 hours to in vitro digested yellow (YOd) or white onion extracts (WOd) that was followed by transcriptomics analysis. The digestion was performed to mimic the digestion that in vivo takes place in the saliva, stomach and small intestine. A main question was to which extent the outcome of the biological interpretation of the transcription analysis (pathway analysis) depend on the model used. One outcome was that mainly processes related to oxidative stress, and especially the Keap1-Nrf2 pathway, were affected by onions in all three models.

Human intestinal tissue samples are barely accessible to study potential health benefits of nutritional compounds. Numbers of animals used in animal trials, however, need to be minimalized. Therefore, we explored the applicability of in vitro (human Caco-2 cells) and ex vivo intestine models (rat precision cut intestine slices and the pig in-situ small intestinal segment perfusion (SISP) technique) to study the effect of food compounds. In vitro digested yellow (YOd) and white onion extracts (WO  ...[more]
