ABSTRACT

In this study, it was aimed to determine the antioxidant and anticancer activities of Sideritis perfoliata methanolic extract (SPE) on cervical cancer cells (HeLa). Different doses (25, 50,100 and 200 µg/mL) of SPE were used to determine proliferation of HeLa cells by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) staining method. Induction of apoptosis was determined by Annexine-V and propidium iodide staining method. Interleukin (IL) 6-8 levels were measured by ELISA method. Antioxidant activities of SPE were determined by DPPH, DNA (plasmid pBR322) protecting and cellular antioxidant activity tests. Some phytochemicals of SPE were also screened by LC-MS-MS. It was determined that SPE reduced the proliferation of HeLa cells and also induced apoptosis. IL6-8 levels importantly decreased at 200 µg/mL. SPE exhibited moderately antioxidant activities in tests used. Among the phenolics identified, vanillic acid had the highest amount. As a result, it was determined to have the anticancer activity of SPE by decreasing cell proliferation, inducing apoptosis and decreasing IL6-8 in HeLa cells.


En este estudio, se tuvo como objetivo determinar las actividades antioxidantes y anticancerígenas del extracto metanólico de Sideritis perfoliata (SPE) en las células de cáncer de cuello uterino (HeLa). Se utilizaron diferentes dosis (25, 50, 100 y 200 µg/mL) de SPE para determinar la proliferación de células HeLa mediante el método de tinción con bromuro de 3-[4,5-dimetiltiazol-2-il] -2,5-difenil-tetrazolio (MTT). La inducción de apoptosis se determinó mediante el método de tinción con anexina-V y yoduro de propidio. Los niveles de interleucina (IL) 6-8 se midieron mediante el método ELISA. Las actividades antioxidantes de SPE se determinaron mediante pruebas de DPPH, protección de ADN (plásmido pBR322) y actividad antioxidante celular. Algunos fitoquímicos de SPE también se analizaron mediante LC-MS-MS. Se determinó que SPE redujo la proliferación de células HeLa y también indujo apoptosis. Los niveles de IL6-8 disminuyeron de manera importante a 200 µg/mL. SPE mostró actividades moderadamente antioxidantes en las pruebas utilizadas. Entre los fenólicos identificados, el ácido vainílico tuvo la mayor cantidad. Como resultado, se determinó que tenía la actividad anticancerígena de SPE al disminuir la proliferación celular, inducir apoptosis y disminuir la IL6-8 en las células HeLa.
