Abstract


The use of plants is as old as the mankind. Natural products are cheap and claimed to be safe. They are also suitable raw material for production of new synthetic agents. Rosemary (Rosmarinus officinalis Linn.) is a common household plant grown in many parts of the world. It is used for flavouring food, a beverage drink, as well as in cosmetics; in folk.medicine it is used as an antispasmodic in renal colic and dysmenorrhoea, in relieving respiratory disorders and to stimulate growth of hair. Extract of rosemary relaxes smooth muscles of trachea and intestine, and has choleretic, hepatoprotective and antitumerogenic activity. The most important constituents of rosemary are caffeic acid and its derivatives such as rosmarinic acid. These compounds have antioxidant effect. The phenolic compound, rosmarinic acid, obtains one of its phenolic rings from phenylalanine via caffeic acid and the other from tyrosine via dihydroxyphenyl-lactic acid. Relatively large-scale production of rosmarinic acid can be obtained from the cell culture of Coleus blumei Benth when supplied exogenously with phenylalanine and tyrosine. Rosmarinic acid is well absorbed from gastrointestinal tract and from the skin. It increases the production of prostaglandin E2 and reduces the production of leukotriene B4 in human polymorphonuclear leucocytes, and inhibits the complement system. It is concluded that rosemary and its constituents especially caffeic acid derivatives such as rosmarinic acid have a therapeutic potential in treatment or prevention of bronchial asthma, spasmogenic disorders, peptic ulcer, inflammatory diseases, hepatotoxicity, atherosclerosis, ischaemic heart disease, cataract, cancer and poor sperm motility.

Экспрессия микрорнк-15b и гликозилтрансферазы GCNT3 коррелирует с противоопухолевой эффективности розмарина дитерпены в толстой кишки и поджелудочной железы.

Колоректального рака и рака поджелудочной железы остаются важными факторами рака смертности бремя и, следовательно, новых терапевтических подходов срочно необходимы. Розмарин (Rosmarinus officinalis L.), экстракты и ее компонентов " зарегистрировано в качестве естественных мощным антипролиферативным средств против раковых клеток. Однако, потенциально применять розмарин в качестве дополнительного подхода для рака терапии, дополнительной информации относительно наиболее эффективного состава, его противоопухолевое действие in vivo и его основных молекулярных медиаторов по-прежнему нужен. В этой работе, пять carnosic кислоты богатых сверхкритических экстрактов розмарина с разных химических составов были исследованы на их противоопухолевую активность как in vivo (in nude mice) и in vitro в отношении толстой кишки и поджелудочной железы ячеек. Мы обнаружили, что противоопухолевый эффект carnosic кислоты вместе с carnosol была выше, чем сумма их эффектов по отдельности, что поддерживает использование экстракт розмарина в целом. Кроме того, Гена и микрорнк выражение анализы были проведены для выяснения ее противоопухолевый механизм, показывая, что up-регуляции обменно-связанных генов GCNT3 и down-регуляции его потенциал эпигенетические модулятор мир-15b коррелируют с противоопухолевым действием розмарина. Кроме того, плазматических мир-15b вниз-регулирование было обнаружено после того, как in vivo лечение с розмарином. Наши результаты поддерживают использование carnosic богатой кислоты экстракт розмарина в качестве дополнительного подхода в толстой кишки и поджелудочной железы рак и указывают на то, что GCNT3 выражения могут быть вовлечены в его противоопухолевый механизм, и что мир-15b могут быть использованы в качестве неинвазивных биомаркеров для мониторинга розмарина противораковый эффект.

Abstract


Colorectal and pancreatic cancers remain important contributors to cancer mortality burden and, therefore, new therapeutic approaches are urgently needed. Rosemary (Rosmarinus officinalis L.) extracts and its components have been reported as natural potent antiproliferative agents against cancer cells. However, to potentially apply rosemary as a complementary approach for cancer therapy, additional information regarding the most effective composition, its antitumor effect in vivo and its main molecular mediators is still needed. In this work, five carnosic acid-rich supercritical rosemary extracts with different chemical compositions have been assayed for their antitumor activity both in vivo (in nude mice) and in vitro against colon and pancreatic cancer cells. We found that the antitumor effect of carnosic acid together with carnosol was higher than the sum of their effects separately, which supports the use of the rosemary extract as a whole. In addition, gene and microRNA expression analyses have been performed to ascertain its antitumor mechanism, revealing that up-regulation of the metabolic-related gene GCNT3 and down-regulation of its potential epigenetic modulator miR-15b correlate with the antitumor effect of rosemary. Moreover, plasmatic miR-15b down-regulation was detected after in vivo treatment with rosemary. Our results support the use of carnosic acid-rich rosemary extract as a complementary approach in colon and pancreatic cancer and indicate that GCNT3 expression may be involved in its antitumor mechanism and that miR-15b might be used as a non-invasive biomarker to monitor rosemary anticancer effect.
