Abstract

Breast cancer is the main cause of cancer death among women, especially breast cancer metastasis. Metastasis process begins with the ability of cell cancer invasion. Doxorubicin, a antracycline chemotheraphy, is known to induce TGFβ1, thus promote invasion. The aim of this study is to optimize doxorubicin doses to induce lamellipodia formation in 4T1 and MCF-7/HER2 cells. Lamellipodia formation was observed by morphological changes using microscope inverted. The effect of doxorubicin on cell viability was analyzed using MTT assay. Rac1 expression after doxorubicin exposure was determined by western blotting. Lamellipodia formation was observed by morphological change of the cell at the dose 10, 25, 50 and 100 nM. Doxorubicin at the dose of 10 nM could induced lamellipodia formation without affect cell viability in both 4T1 and MCF-7/HER2 cells.  Doxorubicin induced cell cycle arrest at G2/M phase at all doses. Doxorubicin 10 nM also decrease Rac1 expression compared to control.Key words: Doxorubicin, lamellipodia, Rac1, migration.

Abstract

ABM (Agaricus blazei Murill) is a basidiomycetes fungus. ABM is used by people for the treatment of diabetes, antihypertention, anticholesterol, anticancer, and immunostimulant. ABM contains terpene, steroids, agaritine, vitamin C, vitamin E, and betaglucane. In this research, ABM extract was tested as an anti-breast cancer in vitro using MCF-7 breast cancer cells. The extract was obtained from the multistage extraction process of several solvents in turn, the solvent used, among others, n-hexane, dichloromethane (DCM), chloroform, ethyl acetate, butanol, and water. The results of the research were the obtained IC50 value from n-hexane extract 247,17 μg /ml; extract DCM 227μg/ml ; chloroform extract 215,64 μg /ml ; extract of ethyl acetate 234,9 μg/ml ; butanol extract 500,78 μg/ml; while the water extract was inactive. Based on these results can be considered for further research to fractionate in order to know which class compounds have the potency as anticancer within the extracts.Key words : Agaricus blazei, multistage extraction, MCF-7 cells.

Abstract

Exposure of genotoxic substances come from various sources such as food additives. The aim of this study is to evaluate the genotoxicity of food additives in CHO-K1 cells by micronucleus test flow cytometry. The food additives: sodium saccharine (SS), monosodium glutamate (MSG), and sodium benzoate (SB) were assessed by in vitro cytotoxicity and genotoxicity using Chinese Hamster Ovary-K1 (CHO-K1) cells. The cytotoxic effect of those compounds was evaluated by MTT Assay on CHO-K1 Cells. The genotoxic evaluation was observed by in vitro micronucleus test by flowcytometry with double staining method. The results showed that the three compounds did not perform cytotoxic effect, increased the frequency of micronucleus, and changed the cell cycle profiles. In general, these studies obtained that none of three food additives showed cytotoxic and genotoxic effect on CHO-K1 cells. Micronucleus test using flow cytometry is suitable for this purpose study.Key words : food additives, genotoxic, cytotoxic, micronucleus

Abstract

Due to severe side effect and non-specific chemotherapeutic agent, screening and discovery for cancer therapy are still working, especially from natural resources. Traditionally, people used herbal medicine either to prevent or cure diseases. One of herbal that commonly used in Indonesia is Alpinia galangal. Previous study stated that active compound is acetoxy chavicol acetate (ACA) and active as anticancer. This research aimed to determine ACA concentration and cytotoxic activity of Alpinia galanga extract (AGE) from three local markets on HeLa, MCF7 and T47D cell lines. The galangal used from three local markets namely Pasar Legi Surakarta, Beringharjo Yogyakarta, and Wonogiri. The extraction was performed by maceration using 96% ethanol as solvent. ACA quantitation using UV spectrophotometer at λ = 208.5 nm. Samples were prepared by liquid-liquid extraction using an ethyl acetate. Cytotoxic activities were performed by MTT assay. The result showed that the concentration of ACA of AGE from the three local markets were 3.798; 0.035; and 0.009 % w/w, respectively. Cytotoxic activity, describes as IC50 value, on HeLa cell line of AGE from three local markets, in order were 13.26; 36.32 and > 100 µg/ mL. Meanwhile, AGE from Pasar Legi on MCF7 and T47D cell lines have IC50 value of 15.80; 12.50 µg/ mL, respectively. In contrast, two other samples have IC50 values of greater than 100 µg/ mL. The highest activity was from the highest concentration of ACA on the samples.Key words: Alpinia galanga, HeLa, T47D, MCF7 and Acetoxy chavicol acetate

Abstract

Cisplatin (cisp) is the first line chemotherapeutic agent for several cancer diseases which can cause significant side effects and cellular resistance. Combination-chemotherapy treatment (co-chemotherapy) was reported to be able to reduce cisp effects. Therefore, this study was carried out to investigate the cytotoxic activity of ethyl acetate fraction of C. sappan (EFC) in combination with cisp by observing apoptosis induction and cell cycle profile. Cytotoxic activity was evaluated by MTT assay. Cell cycle and apoptosis analysis were performed using flow cytometry and p53 expression was analyzed using immunocytochemistry. EFC performed cytotoxic effect on HeLa cells by showing morphological changes such as cell shrinkage, rounding and decreasing of cells viability in concentration dependent manner, giving IC50 value of 65 μg/mL. Combination of EFC and cisp in low concentration decreased cell viability into 36.86%. Further assay indicated that this combination caused redistribution of cell cycle arrest in G1 and S phases through p53 stabilization in nucleus. However, that mechanism was not followed by apoptosis. These results provide evidence to support EFC development as the enhancer of cisp effect, by improving its cytotoxicity on HeLa cells. EFC increases HeLa cells sensitivity to cisp through G1 and S cells’ arrest depending on p53 expression. Key words: co-chemotherapy, EFC, cervix cancer HeLa cells, p53, G1 and S arrest.

Abstract

Metastatic process becomes a major problem in advanced cancer cases. Natural compounds found in several plants in Indonesia have a potency to be developed as chemoterapeutic agent which are targeted to metastatic process. Jure leaves (Nerium indicum) which contain oleandrin and cinnamaldehyde in cinnamon bark (Cinnamomum burmannii) reported to have cytotoxic activity on several cancer cells, but their activities on metastasic process have never been explored. This research aims to reveal and to compare their anti-metastatic effect toward 4T1 breast cancer cells. The cytotoxicity of jure leaves extract (JLE) and cinnamon essential oil (CEO) was obtained by MTT assay. Metastatic process mainly on cell migration was examined by scratch wound healing assay while MMP-9 expression that described the invassion process was observed by gelatin zymography assay. Molecular interaction between their active compounds and MMP-9 receptor was predicted by molecular docking. The result showed that treatment with JLE and CEO inhibited the growth of 4T1 cells with IC50 value of 125 µg/mL and 2.5 µg/mL, respectively. In addition, JLE performed inhibitory effect of cell migration better than CEO. Meanwhile, both JLE and CEO decreased MMP-9 protein expression. Thus, JLE and CEO have potentials to be developed as an anti-metastatic agent and JLE could be more effective.Key words: Nerium indicum, Cinnamomum burmannii, anti-metastasis, scratch assay, gelatin zimography
