ИНГИБИРОВАНИЕ ЭКСПРЕССИИ АТЕРОГЕННЫХ МИКРОРНК-24, МИК POP НК -125 И ИНДУЦИРОВАНИЕ ЭКСПРЕССИИ АНТИАТЕРОГЕННЫХ МИКРОРНК- 126, МИКРОРНК -222, МИКРОРНК -LET7B INHIBITION OF EXPRESSION OF ATHEROGENIC MICRORNA-24, MIC POP NK-125 AND INDUCTION OF EXPRESSION OF ANTIATHEROGENIC MICRORNA-126, MICRORNA-222, MICRORNA-LET7B
Изобретение относится к области клинической медицины, а именно к возможности влияния на профиль экспрессии определённых микроРНК в плазме крови человека посредством приема экстракта дудника, что позволит использовать в дальнейшем экстракт дудника в качестве защитного средства от действия определённых эпигенетических атерогенных факторов в плазме крови человека. The invention relates to the field of clinical medicine, namely to the possibility of influencing the expression profile of certain microRNAs in human blood plasma by taking angelica extract, which will make it possible to use angelica extract in the future as a protective agent against the action of certain epigenetic atherogenic factors in human blood plasma.
Из уровня техники известен следующий метод применения экстракта дудника «Средство для предотвращения старения кожи или улучшения состояния её состояния на фоне старения» [US20040223942A1, 6.03.2003, Япония]. Данный метод подразумевает использование экстракта дудника в составе композиции компонентов, влияющих на функциональное состояние фибробластов кожи за счёт повышения экспрессии Rho киназы или киназы лёгкой цепи миозина. Основным отличием данного метода является отсутствие эффекта от применения дудника на эпигенетические атерогенные и антиатерогенные факторы, в частности, на уровень экспрессии в плазме крови атерогенных микроРНК-24, -125 и антиатерогенных микроРНК -126,-222,-let7b. Known from the prior art is the following method of using angelica extract "An agent for preventing skin aging or improving its condition against the background of aging" [US20040223942A1, 6.03.2003, Japan]. This method involves the use of angelica extract as part of a composition of components that affect the functional state of skin fibroblasts by increasing the expression of Rho kinase or myosin light chain kinase. The main difference of this method is the lack of effect from the use of angelica on epigenetic atherogenic and antiatherogenic factors, in particular, on the level of expression in blood plasma of atherogenic microRNA-24, -125 and antiatherogenic miRNA -126, -222, -let7b.
Техническим результатом заявленного способа является возможность влияния на профиль экспрессии определённых микроРНК (микроРНК-24, - 125, -126, -222, -let7b) в плазме крови за счёт ингибирования экспрессии атерогенных микроРНК (микроРНК-24, -125) и индуцирования экспрессии антиатерогенных микроРНК (микроРНК- 126, -222, -let7b) посредством приема экстракта дудника. Вышеприведённый технический результат достигается благодаря тому, что способ включает последовательное выполнение следующих стадий: 1) получение экстракта дудника; 2) приём полученного экстракта дудника по 5 капель на 10 кг веса ежедневно в течение 4 недель. The technical result of the claimed method is the possibility of influencing the expression profile of certain miRNAs (miRNA-24, -125, -126, -222, -let7b) in blood plasma by inhibiting the expression of atherogenic microRNAs (miRNA-24, -125) and inducing the expression of antiatherogenic miRNA (miRNA-126, -222, -let7b) by taking angelica extract. The above technical result is achieved due to the fact that the method includes the sequential execution of the following steps: 1) obtaining an extract of angelica; 2) taking the resulting angelica extract, 5 drops per 10 kg of body weight daily for 4 weeks.
Получают экстракт дудника путем сушки корней растения дудник в течение недели при температуре 24±1°С, затем измельчают высушенные корни до порошкообразного состояния, далее к 100 г измельчённого дудника добавляют 100 мл дистилированной воды, перемешивают, затем полученную смесь кипятят на водной бане в течение 1-3 часа, до уменьшения объёма жидкости в 10 раз, проводят его центрифугирование при 15000 оборотах/минуту в течение 30 минут при температуре 24±1°С, затем полученный супернатант фильтруют на фильтре Whatman №1, далее раствор концентрируют с помощью роторного испарителя Concentrator plus (Eppendorf) и насоса WP6122050 (Millipore) при следующих условиях: 1400 оборотов/мин., температура 30°С, в течении 16 часов, уровень вакуума 10 мбар. An extract of angelica is obtained by drying the roots of the angelica plant for a week at a temperature of 24 ± 1 ° C, then the dried roots are crushed to a powder, then 100 ml of crushed angelica are added to 100 ml of distilled water, stirred, then the resulting mixture is boiled in a water bath for 1-3 hours, until the volume of liquid decreases by 10 times, it is centrifuged at 15,000 rpm for 30 minutes at a temperature of 24 ± 1 ° C, then the resulting supernatant is filtered on a Whatman No. 1 filter, then the solution is concentrated using a rotary evaporator Concentrator plus (Eppendorf) and pump WP6122050 (Millipore) under the following conditions: 1400 rpm, temperature 30°C, for 16 hours, vacuum level 10 mbar.
Отбирают 5 мл из полученного водного экстракта дудника и разводят 1:5 в физиологическом растворе (0,9 % водном растворе хлорида_натрия) и рекомендуют к приёму per os в объёме 5 капель на каждые 10 кг веса пациента. Take 5 ml from the resulting aqueous extract of angelica and dilute 1:5 in physiological saline (0.9% aqueous sodium chloride solution) and recommend taking per os in a volume of 5 drops for every 10 kg of patient weight.
Пример «Ингибирование экспрессии атерогенных микроРНК-24, -125 и индуцирование экспрессии антиатерогенных микроРНК-126, -222, -let7b по данным исследования микроРНК плазмы крови человека на фоне приёма экстракта дудника ежедневно в течение 4 недель в дозировке 5 капель на 10кг веса». Example "Inhibition of the expression of atherogenic microRNA-24, -125 and induction of expression of anti-atherogenic microRNA-126, -222, -let7b according to the study of microRNA in human blood plasma against the background of taking angelica extract daily for 4 weeks at a dosage of 5 drops per 10 kg of weight."
Мужчина 55 лет 82кг и женщина 43 лет 75кг принимали водный экстракт дудника, приготовленный вышеприведенным способом, ежедневно в течение 4 недель в дозировке 5 капель на 10кг веса. Уровень экспрессии атерогенных и антиатерогенных микроРНК в плазме крови определяли на 1-ый и на 28-ой день приёма водного экстракта дудника.A 55-year-old man (82 kg) and a 43-year-old woman (75 kg) took an aqueous extract of angelica prepared as described above daily for 4 weeks at a dosage of 5 drops per 10 kg of body weight. Level the expression of atherogenic and anti-atherogenic miRNAs in blood plasma was determined on the 1st and 28th day of taking an aqueous extract of angelica.
Для оценки уровня экспрессии атерогенных и антиатерогенных микроРНК проводили выделение микроРНК из периферической венозной крови (5мл, собрана в вакуумную пробирку с антикоагулянтом) на наборах RNeasy Mini Kit (Qiagen, Германия), затем проводили реакцию обратной транскрипции на наборах miScript II RT kit (Qiagen, Германия) и постановку ПЦР в реальном времени с праймерами к микроРНК- 24, 125, 126, 222, let-7b, 16. Уровень экспрессии приведён относительно уровня экспрессии микроРНК 16 (miRNeasy Mini Kit, miScript II RT Kit, Qiagen, Германия). Значения микроРНК представлены в виде отношения уровня экспрессии исследуемой микроРНК, представленного в виде число копий исследуемой микроРНК/мкл к уровню экспрессии микроРНК! 6, также представленному в виде число копий микроРНК 16/мкл. Данный подход является общепринятым для отражения динамики уровней экспрессии микроРНК, т.к. уровень экспрессии микроРНК 16 является стабильным относительно уровней экспрессии остальных микроРНК и может выступать в качестве референсного, относительного которого оцениваются уровни экспрессии остальных микроРНК и может происходить оценка уровней экспрессии микроРНК между разными объектами (клеточными линиями, культурами, живыми организмами). To assess the level of expression of atherogenic and antiatherogenic miRNAs, miRNAs were isolated from peripheral venous blood (5 ml, collected in a vacuum tube with anticoagulant) using RNeasy Mini Kits (Qiagen, Germany), then reverse transcription was performed using miScript II RT kits (Qiagen, Germany). Germany) and real-time PCR with primers to miRNA-24, 125, 126, 222, let-7b, 16. The expression level is given relative to the expression level of miRNA 16 (miRNeasy Mini Kit, miScript II RT Kit, Qiagen, Germany). The microRNA values are presented as the ratio of the expression level of the studied microRNA, presented as the number of copies of the studied microRNA/µl, to the expression level of the microRNA! 6, also represented as miRNA copy number 16/µl. This approach is generally accepted for reflecting the dynamics of microRNA expression levels, since the expression level of microRNA 16 is stable relative to the expression levels of other microRNAs and can act as a reference, relative to which the expression levels of other microRNAs are evaluated, and the expression levels of microRNAs between different objects (cell lines, cultures, living organisms) can be assessed.
