    <p>Цель работы: Исследование апоптотической гибели лимфоцитов периферической крови в отдаленные сроки у лиц, подвергшихся хроническому радиационному воздействию и оценка связи аллельных вариаций rs4645878, rs2279115, rs28362491, rs664677, rs1042522, rs1801270, rs2279744 генов BAX, BCL2, NFkB1, ATM, TP53, CDKN1A, MDM2 с частотой лимфоцитов, погибших путем апоптоза в крови у жителей прибрежных сел реки Течи.&#13;
Материал и методы: Исследование апоптоза и генотипирование проводилось в отдаленные сроки у 390 человек, подвергшихся хроническому низкоинтенсивному радиационному воздействию в результате загрязнения жидкими радиоактивными отходами речной системы Теча–Исеть–Тобол производственным объединением «Маяк». Проточной цитометрией оценивалась ранняя стадия апоптоза по наличию фосфатидилсерина на поверхности мембран клеток методом Annexin V Apoptosis Detection Kit I и поздняя стадия апоптоза методом TUNEL. Методом ПЦР в реальном времени проводилось генотипирование аллельных вариаций rs4645878, rs2279115, rs28362491, rs664677, rs1042522, rs1801270, rs2279744 генов BAX, BCL2, NFkB1, ATM, TP53, CDKN1A, MDM2 в группе облученных лиц.&#13;
Результаты: В результате исследования было установлено, что у лиц, облучение которых началось в период внутри­утробного развития и продолжалось в постнатальном периоде, количество клеток на ранней стадии апоптоза статистически значимо выше, по сравнению с лицами, подвергшимися облучению только в постнатальном периоде. При этом количество лимфоцитов на стадии фрагментации ДНК в группе облученных in utero, наоборот, снижается как относительно группы облученных постнатально, так и не облученных лиц. Также у облученных in utero наблюдается слабая отрицательная корреляционная связь внутриутробных доз облучения красного костного мозга (ККМ), тимуса и вторичных лимфоидных органов с количеством клеток на поздней стадии апоптоза. Установлено влияние аллельной вариации rs4645878 гена BAX на количество лимфоцитов на ранней стадии апоптоза у жителей прибрежных сел реки Течи. У носителей генотипа С/С по аллельной вариации rs4645878 гена BAX регистрируется статистически значимое снижение количества клеток на ранней стадии апоптоза, по сравнению с носителями генотипов T/T и T/C. &#13;
Заключение: У жителей прибрежных сел реки Течи, подвергшихся радиационному воздействию в период внутриутробного развития, наблюдается различия в частоте апоптотической гибели лимфоцитов периферической крови по сравнению с необлучёнными лицами и лицами, облученными в постнатальном периоде. Наличие полиморфных вариантов генов, регулирующих апоптоз, может модифицировать ответ лимфоцитов крови на воздействие радиации в широком диапазоне доз на ККМ.</p>

    <p>Purpose: Study the apoptotic death of peripheral blood lymphocytes in long-term period in persons exposed to chronic radiation exposure, and analysis of association of the polymorphic regions rs4645878, rs2279115, rs28362491, rs664677, rs1042522, rs1801270, rs2279744 of the BAX, BCL2, NFkB, ATM, TP53, CDKN1A, MDM2 genes with apoptotic lymphocytes frequency in residents of the coastal villages of the Techa River.&#13;
Material and methods: The study of apoptosis and genotyping was conducted in 390 persons exposed to chronic radiation exposure as a result of Mayak PA radioactive waste releases into the Techa–Iset–Tobol river system. The early stage of apoptosis was assessed on a flow cytometer by the presence of phosphatidylserine on the surface of the cell membranes using the Annexin V Apoptosis Detection Kit I and the late stage of apoptosis using the TUNEL method. Real-time PCR genotyping was performed of allelic variations of rs4645878, rs2279115, rs28362491, rs664677, rs1042522, rs1801270, rs2279744 of BAX, BCL2, NFkB, ATM, TP53, CDKN1A, MDM2 genes in a group of irradiated individuals.&#13;
Results: The number of cells at the early stage of apoptosis is statistically significantly increased in individuals whose irradiation began during the period of intrauterine development and continued in the postnatal period compared to individuals exposed only in the postnatal period. At the same time, the number of lymphocytes at the stage of DNA fragmentation in the group irradiated in utero is lower than in the group irradiated postnatally and non-irradiated individuals. Also, a weak negative correlation between intrauterine doses of RBM irradiation and the doses of thymus and peripheral lymphoid organs with the number of cells in the late stage of apoptosis in individuals irradiated in utero. The influence of allelic variation rs4645878 of the BAX gene was established on the number of lymphocytes at the early stage of apoptosis in residents of coastal villages of the Techa River. A statistically significant decrease in the number of cells at an early stage of apoptosis is observed in C/C genotype carriers according to the allelic variation rs4645878 of the BAX gene compared with carriers of the T/T and T/C genotypes.&#13;
Conclusion: Residents of coastal villages of the Techa River exposed to radiation during the period of prenatal development, there are differences in the frequency of apoptotic death of peripheral blood lymphocytes compared with non-irradiated persons and persons who were irradiated in the postnatal period. SNPs of apoptosis-regulating genes can modify the response of blood lymphocytes to radiation in a wide range of doses RBM.</p>
