Экспрессия miR-146а в образцах РЖ понижалась по мере вовлечения регионарных лимфоузлов в метастатический процесс. Была обнаружена отрицательная корреляция уровня экспрессии miR-146а со степенью поражения регионарных лимфоузлов (коэффициент корреляции по Спирмену (R) составил R = - 0,61; p=0,005). Напротив, экспрессия NF-kB повышалась при поражении лимфоузлов метастазами. Обнаружена обратная корреляция между miR-146a и NF-kB (R = -0,76; p=0,03). Впервые обнаруженная отрицательная корреляция экспрессии между miR-146a и NF-kB может указывать на активацию сигнального пути NF-kB в клетках РЖ при снижении экспрессии miR-146a. Видимо, этот сигнальный путь имеет значение при развитии метастазов РЖ.</p></abstract><trans-abstract xml:lang="en"><p>The expression levels of miR-146a and the target gene of this miRNA, NF-kB, in gastric cancer (GC) samples at different stages of metastasis development were studied. The expression of miR-146a in the samples of the GC decreased with the involvement of regional lymph nodes in the metastatic process. A negative correlation was found between the expression level of miR-146a and the number of regional lymph nodes damage (Spearman’s correlation coefficient (R) was R = - 0.61; p 0.005). On the contrary, NF-κB gene expression increased with lymph node metastases. An inverse correlation was found between miR-146a and NF-κB (R = -0.76; p 0.03). The first detected negative correlation of expression between miR-146a and NF-κB may indicate activation of the NF-κB signaling pathway in GC cells with a decrease in miR-146a expression. Apparently, this signaling pathway is important in the development of metastases of gastric cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>метастазирование</kwd><kwd>miR-146a</kwd><kwd>NF-κB</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>metastasis</kwd><kwd>expression of miR-146a</kwd><kwd>NF-κB</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
