A rare recessive form of the disease may be caused by a mutation in the PARK2 gene, whose product, Parkin, controls mitophagy and programmed cell death. The level of pro- and anti-apoptotic factors of the Bcl-2 family was determined in dopaminergic neurons derived from the induced pluripotent stem cells of a healthy donor and a Parkinson’s disease patient bearing PARK2 mutations. Western blotting was used to study the ratios of Bax, Bak, Bcl-2, Bcl-XL, and Bcl-W proteins. The pro-apoptotic Bak protein level in PARK2-neurons was shown to be two times lower than that in healthy cells. In contrast, the expression of the anti-apoptotic factors Bcl-XL, Bcl-W, and Bcl-2 was statistically significantly higher in the mutant cells compared to healthy dopaminergic neurons. These results indicate that PARK2 mutations are accompanied by an imbalance in programmed cell death systems in which non-apoptotic molecular mechanisms play the leading role.</p></abstract><trans-abstract xml:lang="ru"><p>Болезнь Паркинсона обусловлена дегенерацией дофаминергических нейронов среднего мозга. Причиной редкой рецессивной формы этого заболевания могут быть мутации гена PARK2, продукт которого, паркин, контролирует процессы митофагии и программируемой клеточной гибели. Определен уровень про- и антиапоптотических факторов семейства Bcl-2 в дофаминергических нейронах, полученных из индуцированных плюрипотентных стволовых клеток здорового донора и пациента с болезнью Паркинсона - носителя мутаций PARK2. Методом Вестерн-блотинга проанализированы соотношения белков Bax, Bak, Bcl-2, Bcl-XL и Bcl-W. Показано, что уровень проапоптотического белка Bak в PARK2-нейронах вдвое ниже по сравнению со здоровыми клетками. Напротив, экспрессия антиапоптотических факторов Bcl-XL, Bcl-W и Bcl-2 статистически значимо увеличена в мутантных клетках по сравнению со здоровыми дофаминергическими нейронами. Полученные результаты показывают, что мутации PARK2 сопровождаются разбалансировкой систем программируемой клеточной гибели, в которой ведущая роль принадлежит неапоптотическим молекулярным механизмам.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Parkinson’s disease</kwd><kwd>dopaminergic neurons</kwd><kwd>induced pluripotent stem cells</kwd><kwd>PARK2</kwd><kwd>mutation</kwd><kwd>programmed cell death</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>дофаминергические нейроны</kwd><kwd>индуцированные плюрипотентные стволовые клетки</kwd><kwd>PARK2</kwd><kwd>мутации</kwd><kwd>программируемая клеточная гибель</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation (grant No. 14-15-01047).</funding-statement><funding-statement xml:lang="ru">Работа поддержана РНФ (грант № 14-15-01047).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Jenner P., Morris H.R., Robbins T.W., Goedert M., Hardy J., Ben-Shlomo Y., Bolam P., Burn D., Hindle J.V., Brooks D. // J.
