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

Effective and selective chemoterapeutic and chemopreventive agent is needed to cure breast and cervical cancers. One of the potential natural material is mangosteen peel (Garcinia mangostana). In this study, we observed cytotoxic effect of ethanolic extract of mangosteen peel (EMP) on HeLa cells line and T47D cells line. The cytotoxic effect was determined using MTT assay.EMP showed cytotoxic effect on T47D cells and HeLa cells with IC50 values of 2.07 μg/ml and 10.58 µg/ml respectively. Molecular docking simulation was done to predict the molecular mechanism of active compund in mangosteen peel extract, α-mangostin, in NFқB pathway which is one of the potential pathway to induce cytotoxicity on T47D and HeLa cells. Docking was done using PLANTS software and the binding score between α-mangostin and proteasom is -78,12, whereas the binding score between α-mangostin and IKK is -86.84. These results showed the possiblity mechanism of mangostin peel extract containing α-mangostin inhibits IKK activation in NFқB pathway. Based on this study, we conclude that mangosteen peel extract is potential to be developed as chemopreventive agent toward cervical and breast cancers.Keywords: Mangosteen peel (Garcinia mangostana), cytotoxic, T47D cells, HeLa cells, NFқB

Abstract

For more than four decades, combination chemotherapy (co-chemotherapy) has been employed as a means to increase the effectiveness of chemotherapy regiments. The aim of our research is to investigate the activity of Moringa oleifera L. (tanaman kelor) ethanolic extract (MEE) as a co-chemotherapy agent with 5-fluorouracil (5-FU) on WiDr colon cancer cell line. Evaluation of MEE potency as a co-chemotherapy agent with 5-FU was based on cytotoxic activity based on percent cell viability via MTT assay, and based on apoptosis observation via the double staining method using acrydin orange – ethidium bromide (AE) as the staining reagent.Cytotoxicity evaluation of single treatment using concentrations of 5, 20, 50, 100,125, and 250 µg/ml of MEE reduced cell viability 24 hours post-treatment. 5, 50, and 250 µg/ml of MEE was chosen as the combination concentrations with 1000 µM 5-FU. MTT assay 24 hours and 48 hours post-combination treatment showed significant cell viability reduction in comparison to those of single treatments. Apoptosis observation using the double staining method shows the presence of apoptotic cells 48 hours post combination treatment. MEE is a potential co-chemotherapy agent by increasing the sensitivity of WiDr colon cancer cell line towards 5-FU.Keywords: co-chemotherapy, 5-fluorouracil, Moringa oleifera L., colon cancer
