Введение. Дисбаланс аминотиолового обмена – потенциальный фактор риска злокачественной трансформации клеток и развития онкологических заболеваний, в том числе опухоли молочной железы с лидирующей мировой позицией в структуре онкологической заболеваемости. Цель исследования – обобщение имеющихся данных об особенностях метаболизма тиолов как одной из причин, способствующих развитию и прогрессированию рака молочной железы. Материал и методы. По базам данных Web of Science, Scopus, MedLine, The Cochrane Library, PubMed производился поиск литературных источников, опубликованных с 1999 по 2022 г., содержащих сведения по данной проблеме и дающих возможность оценить роль тиолзависимых метаболических нарушений регуляции тканевого окислительно-восстановительного равновесия в онкогенезе рака молочной железы. Результаты. В обзоре рассмотрены результаты как собственных, так и международных исследований по раку молочной железы, которые свидетельствуют о том, что дисбаланс тиоловых соединений, необходимых для поддержания умеренно восстановительной клеточной среды, противодействующей окислительному стрессу в ходе клеточного метаболизма и детоксикации, в условиях опухолевого прогрессирования может спровоцировать перепрограммирование ведущих звеньев антибластомной резистентности, способствующих онкопрогрессированию. Заключение. Более детальное исследование механизмов метаболизма аминотиолов в условиях рака молочной железы подчеркивает их особое значение для стабилизации клеточного генома и обеспечения антитоксической защиты клетки, а также понимания важной роли тиолов как координационного центра в окислительно-восстановительной сигнализации. Нарушения на любом этапе метаболизма тиолов могут играть этиологическую роль в онкогенетических патологиях, при этом роль тиолов как сигнальных молекул и особенности регуляции их метаболизма не стоит обобщать в отношении всей группы заболеваний. Определение сывороточных маркеров редокс-состояния у больных раком молочной железы, особенно при проведении противоопухолевой терапии, может служить для объективной оценки эффективности лечения и адаптационных возможностей организма, а также прогнозирования опухолевого роста и оптимизации программы скрининга и профилактики онкологических заболеваний.

Background. Imbalance of aminothiol metabolism is a potential risk factor for malignant transformation of cells and caner development, including breast cancer, which is the most commonly diagnosed cancer in the world. The purpose of the study was to summarize the available data on the characteristics of thiol metabolism as one of the factors contributing to the progression of breast cancer. Material and Methods. Data were searched from 1999 to 2022 using the Web of Science, Scopus, MedLine, The Cochrane Library, PubMed databases, which made it possible to assess the role of thiol-dependent metabolic disturbances in the regulation of tissue redox balance in breast cancer genesis. Results. The review considers the results of both our own data and international studies on breast cancer, which suggest that an imbalance of thiol compounds necessary to maintain a moderately reducing cellular environment that counteracts oxidative stress during cellular metabolism and detoxifcation under conditions of tumor progression can provoke reprogramming of the leading links of antiblastoma resistance, contributing to cancer progression. Conclusion. A more detailed study of the mechanisms of aminothiol metabolism in breast cancer emphasizes their particular importance for stabilizing the cellular genome and providing antitoxic protection of the cell, as well as understanding the important role of thiols as a coordination center in redox signaling. Disturbances at any stage of thiol metabolism can play an etiological role in oncogenetic pathologies, while the role of thiols as signaling molecules and the regulation of their metabolism should not be generalized for the entire group of diseases. Determination of serum markers of the redox state in patients with breast cancer, especially during antitumor therapy, can serve for an objective assessment of the effectiveness of treatment and the adaptive capabilities of the body, as well as predicting tumor growth and optimizing the program for screening and preventing cancer.
