84 Background: The use of medicinal plants has been very common since ancient times, used for the treatment of several diseases such as cancer. In many towns in Mexico are used extracts from plants such as Solanum rastratum Dunal (buffalo bur, spiny nightshade, Colorado bur, Kansas thistle, Mexican thistle, and Texas thistle), which has shown to be effective in improving symptoms of some diseases conditions, there are reports indicating its use in the treatment of some types of cancer, such as the breast and cervical cancer. For this reason, in this work the aim was to evaluate the anticarcinogenic effect of extracts of Solanum rastratum Dunal on human breast cancer cells MDA. Methods: The plant was collected, cleaned, separate the different sections, were dried in darkness in special panels at room temperature; subsequently the extracts were prepared from the leaf, stem and flower-fruit using solvents of different polarity (methanol, ethyl acetate and hexane). Extracts were analyzed in cultured MDA cells line and the cytotoxic effect was evaluated by MTT technique. Results: The results showed that the stem and leaf extracts were those which showed higher inhibitory effect on cell viability, with those obtained with ethyl acetate which showed better anti-carcinogenic effect, while the hexane extract of the flower and fruit mixture which was showed higher inhibitory effect on this part of the plant; however generally the ethyl acetate extract obtained from the leaf was the one with greater cytotoxic effect in this cell line. Conclusions: The results of this work lead to the conclusion that is greater cytotoxic effect of ethyl acetate extract of the leaf than the other extracts tested. These results are contrasting with the traditional use of the extract of this plant, since traditionally people employ the aqueous extract of this plant, which would be equivalent to methanolic extract used in this study, which was who presented the lower cytotoxic effect of three solvents studied.

Antitumor Effects

Extracts from the Nepenthes plant have anti-microorganism and anti-inflammation effects. However, the anticancer effect of the Nepenthes plant is rarely reported, especially for breast cancer cells. Here, we evaluate the antitumor effects of the ethyl acetate extract of Nepenthes thorellii x (ventricosa x maxima) (EANT) against breast cancer cells. Cell viability and flow cytometric analyses were used to analyze apoptosis, oxidative stress, and DNA damage. EANT exhibits a higher antiproliferation ability to two breast cancer cell lines (MCF7 and SKBR3) as compared to normal breast cells (M10). A mechanistic study demonstrates that EANT induces apoptosis in breast cancer cells with evidence of subG1 accumulation and annexin V increment. EANT also induces glutathione (GSH) depletion, resulting in dramatic accumulations of reactive oxygen species (ROS) and mitochondrial superoxide (MitoSOX), as well as the depletion of mitochondrial membrane potential (MMP). These oxidative stresses attack DNA, respectively leading to DNA double strand breaks and oxidative DNA damage in γH2AX and 8-oxo-2′deoxyguanosine (8-oxodG) assays. Overall these findings clearly revealed that EANT induced changes were suppressed by the ROS inhibitor. In conclusion, our results have shown that the ROS-modulating natural product (EANT) has antiproliferation activity against breast cancer cells through apoptosis, oxidative stress, and DNA damage.

Beberapa penelitian telah melaporkan bahwa daun <em>M. oleifera </em>mengandung sejumlah senyawa bioaktif yang memiliki potensi sebagai antikanker. Penelitian ini bertujuan untuk mengetahui aktivitas sitotoksik esktrak etanol, fraksi etil asetat dan fraksi n-heksana daun <em>M. oleifera </em>terhadap sel kanker payudara T47D. Daun <em>M. oleifera </em>dimaserasi dengan pelarut etanol 90%. Ekstrak yang diperoleh dipartisi dengan menggunakan pelarut n-heksana dan etil asetat. Masing-masing ekstrak etanol, fraksi etil asetat dan fraksi n-heksana diuji aktivitas sitotoksiknya terhadap sel kanker payudara T47D menggunakan metode MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium).

Voigt) Base Towards T47D Breast Cancer Cells and Chorio Allantoic Membrane (CAM) of Chicken Embryo Induced by bFGF ABSTRACTThis study aims to identify the cytotoxic activity and antiangiogenesis of extract and fraction of (Coccinia Grandis (L.) Voigt) base towards T47D breast cancer cells and Chorio Allantoic Membrane (CAM) of chiken embryo induced by bFGF. The extract was extracted throught maceration method with ethanol 96% soluble. The ethanol extract was then fractionated by the liquid-liquid partition method. The fractions obtained were analyzed qualitatively by the thin layer chromatography (TLC) method. The TLC analysis shows that there are several classes of active compounds, namely alkaloids, flavonoids, tannins, saponons and terpenes. The ethanol extraction was then fractionated using the liquid-liquid extraction. The cytotoxic test was conducted using the T47D breast cancer cells and VERO cells with the MTT assay method which their absorbance were read on ELISA reader with the value of observation parameters IC50. The antiangiogenesis test was conducted using the Chorio Allantoic Membrane (CAM) method of chicken embryo induced with bFGF protein with the new blood vessels count as the observation parameters. The results showed that the extract, n-hexane fraction, ethyl acetate fraction, and water fraction had IC50 values of 500.167; 353.131; 109.975; and 303.990 µg/mL, respectively. Ethyl acetate fraction has the smallest IC50 value so it is continued to the antiangiogenesis test. Ethyl acetate fraction had an antiangiogenesis activity towards Chorio Allantoic Membrane (CAM) with the effective concentration 219,95 µg/mL marked by the angiogenesis inhibitors percentage of 56,78%.Keywords: Antiangiogenesis; Chorio Allantoic Membrane (CAM); Coccinia grandis (L.)
