Показано, что при РМЖ химотрипсинподобная и каспазоподобная активности протеасом в опухолевой ткани выше по сравнению с неизмененной тканью. Выявлено, что при большей распространенности опухолевого процесса увеличивается активность протеасомной системы. В то же время при обширном лимфогенном метастазировании наблюдается значительное угнетение активности протеасом, что в дальнейшем может рассматриваться в качестве неблагоприятного прогностического признака. Кроме того, выявленная динамика функционирования протеасомной системы в зависимости от распространенности онкологического процесса свидетельствует о важной роли внутриклеточного протеолиза в прогрессировании рака молочной железы</p></abstract><trans-abstract xml:lang="en"><p>The chymotrypsin-like and caspase-like proteasome activities were studied in tumor tissues of 74 patients with breast cancer (BC) NМin association with tumor size and lymph node involvement. Chymotrypsin-like and caspase-like proteasome activities were Т1-40-30 higher in breast cancer tissue than in adjacent tissues. We showed that advanced BC is accompanied by increase in chymotrypsin-like and caspase-like proteasome activities. In tumors with lymph node dissemination, proteasome activity was significantly decreased, which may have prospective prognostic value. Taken together, our data indicate an important role of intracellular proteolysis in BC progression.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>активность протеасом</kwd><kwd>лимфогенное метастазирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>proteasome activity</kwd><kwd>lymph node metastasis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кондакова И.
