In this study, immature gilts were exposed to NOEL doses of ZEN (40 \u03bcg\/kg\/d), DON (12 \u03bcg\/kg\/d), ZEN+DON (40+12 \u03bcg\/kg\/d), and <jats:italic>placebo<\/jats:italic> (negative control group) for 7, 14, 21, 28, 35, and 42 days. Before the treatment, expression levels of the selected miRs were measured in the liver, the duodenum, the jejunum, and the ascending and the descending colon of the gilts. Hierarchical clustering of the tissues by their miR expression profiles was consistent with what would be expected based on the anatomical locations and the physiological functions of the organs, suggesting that functions of the miRs are related to the specificities of the tissues in which they are expressed. A subset of 2 pairs of miRs (miR-21+miR-192 and miR-15a+miR-34a), which were assigned to two distinct clusters based on their tissue abundance, was then evaluated in the liver and the ascending and the descending colon during the treatment. The most meaningful results were obtained from the ascending colon, where a significant effect of the treatment was observed, suggesting that during the exposure to mycotoxins, the pathways involved in cell proliferation and survival were disordered. Changes in miR expression in the liver and the descending colon of the treated gilts were smaller, and were associated more with treatment duration than the exposure to ZEN, DON, or ZEN+DON. Further research should focus on identification of genes whose expression is regulated by these aberrantly expressed miRs. This should facilitate understanding of the miRNA-regulated biological effects of mycotoxins.<\/jats:p>","DOI":"10.1515\/pjvs-2015-0004","type":"journal-article","created":{"date-parts":[[2015,5,5]],"date-time":"2015-05-05T15:36:50Z","timestamp":1430840210000},"page":"29-38","source":"Crossref","is-referenced-by-count":28,"title":["MicroRNA expression profiles in liver and colon of sexually immature gilts after exposure to Fusarium mycotoxins"],"prefix":"10.1515","volume":"18","author":[{"given":"P.","family":"Brzuzan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Wo\u017any","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Woli\u0144ska-Nizio\u0142","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Piasecka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Florczyk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Jakimiuk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"G\u00f3ra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.K.","family":"\u0141uczy\u0144ski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Gaj\u0119cki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","reference":[{"key":"ref501","first-page":"115","article-title":"their implications for human and animal Vet","volume":"21","author":"Fink","year":"1999","journal-title":"health"},{"key":"ref751","first-page":"53","article-title":"Differential regulation of microRNAs by revealed by massively parallel sequencing ais a target that induces apoptosis and arrest","author":"Tarasov","year":"2007","journal-title":"Cell Cycle"},{"key":"ref431","first-page":"103","article-title":"Differences in vertebrate microRNA expression","author":"Ason","year":"2006","journal-title":"Proc Natl Acad Sci USA"},{"key":"ref811","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.fct.2006.07.030","article-title":"on the toxicity occurrence metabolism detoxification regulations and intake of zearalenone : an oestrogenic mycotoxin","volume":"45","author":"Zinedine","year":"2007","journal-title":"Review Food Chem Toxicol"},{"key":"ref151","first-page":"232","article-title":"The role of oxidative stress in zearalenone -
