Atypical ductal hyperplasia is a relatively common breast lesion that increases the risk of breast cancer by 3.5 to 5 times. Genomic rearrangements underlying the development of atypical proliferative lesions and breast cancer lead to gene expression changings.<bold>Aim</bold>. To determine the mRNA expression profile of neoplasia and oncogenesis driver genes in atypical ductal hyperplasia of the breast.<bold>Materials and methods.</bold> The real-time reverse transcription polymerase chain reaction was used to explore the expression profile of 46 genes in 107 samples of formalin-fixed paraffin-embedded (FFPE) specimens from atypical ductal hyperplasia, ductal hyperplasia without atypia, ductal carcinoma in situ and normal breast tissue.<bold>Results</bold>. In atypical ductal hyperplasia, we detected changes in the expression of 22 of 46 studied genes, including ESR1, AR, PRLR, FGFR4, MKI67, CCNB1, KIF14, PAK1, MMP11, GATA3, FOXA1, ZNF703, which were upregulated, and MYC, which was downregulated.<bold>Conclusion</bold>. The transcriptional signature of atypical ductal hyperplasia was similar to that of ductal carcinoma in situ and breast cancer of luminal subtypes.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Атипичная протоковая гиперплазия является относительно распространенным поражением молочной железы, которое в 3,5–5,0 раза увеличивает риск развития рака молочной железы. В основе развития атипичных пролиферативных процессов и рака молочной железы лежат изменения в структуре генома, следствием которых становится изменение экспрессии генов.<bold>Цель исследования</bold> – определение профиля экспрессии мРНК драйверных генов неоплазии и онкогенеза при атипичной протоковой гиперплазии молочной железы.<bold>Материалы и методы.</bold> Методом обратной транскрипции и полимеразной цепной реакции выполнено исследование экспрессионного профиля 46 генов в 107 образцах фиксированных в формалине и парафинизированных (FFPE) тканей молочной железы c атипичной протоковой гиперплазией, протоковой гиперплазией без атипии, протоковой карциномой in situ и нормальной ткани.<bold>Результаты</bold>. При атипичной протоковой гиперплазии установлено изменение экспрессии 22 из 46 исследованных генов, включая статистически значимое повышение экспрессии ESR1, AR, PRLR, FGFR4, MKI67, CCNB1, KIF14, PAK1, MMP11, GATA3, FOXA1, ZNF703 и снижение экспрессии MYC по сравнению с нормой.<bold>Выводы</bold>. Транскрипционная сигнатура при атипичной протоковой гиперплазии имела сходство с таковой при протоковой карциноме in situ и люминальных подтипах рака молочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>atypical ductal hyperplasia of the breast</kwd><kwd>premalignant condition</kwd><kwd>breast cancer</kwd><kwd>mRNA profiles of oncogenic driver genes</kwd><kwd>real-time reverse transcription polymerase chain reaction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>атипичная протоковая гиперплазия молочной железы</kwd><kwd>предраковые заболевания</kwd><kwd>рак молочной железы</kwd><kwd>профили мРНК драйверных генов онкогенеза</kwd><kwd>обратная транскрипция и полимеразная цепная реакция в режиме реального времени</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed with partial financial support for scientific research within the framework of the state task “Assessing the individual risk of breast cancer in women with benign diseases (fibrocystic disease) of the mammary glands” (state registration number NIOKTR 121040600432-9).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при частичной финансовой поддержке научных исследований в рамках государственного задания «Оценка индивидуального риска рака молочной железы у женщин с доброкачественными заболеваниями (фиброзно-кистозной болезнью) молочных желез» (номер государственного учета НИОКТР 121040600432-9).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Simpsons J.
