| dc.description.abstract | Introduction: Cancer is a disease with increasing incidence and is the second cause of death worldwide. Phytotherapy is based on the use of plants to treat diseases and is important in the development of new therapeutic strategies such as anti-cancer drugs. The aim of this work was to perform a study on the effect of aqueous and ethanolic extracts of Gentiana lutea in two human cancer cell lines, human cervical cancer (HeLa) and breast adenocarcinoma (MCF-7). Methods: The aqueous and ethanolic extracts were prepared both with MEM culture medium at different concentrations as follow: 31.25 mu g/ml, 62.5 mu g/ml, 125 mu g/ml, 250 mu g/ml and 500 mu g/ml. Cells were plated in 96-multiwell culture plates at a density of 10(4) and 10(5) cells/well for each extract concentration. Untreated cancer cells acted as a control group. Results: The results exhibited a hyperbolic relationship between growth inhibition for HeLa/and MCF-7 cell lines and ethanol extract concentration revealed the highest inhibition observed at 500 mu g/ml for both cell concentrations. MCF-7 cell line was inhibited when exposed to the ethanol extract of Gentiana lutea (highest growth inhibition of 25%). Aqueous plant extracts exhibited a different behavior since there was an increase (15-20%) in cell growth at low extract concentrations while a cell growth inhibition (15-25%) was only observed at the highest extract concentration. Conclusion: The present results strongly suggest growth inhibition of carcinoma cell lines by the hyperbolic relationship for both plant extracts and it will require a detailed future research to understand its molecular mechanism. | pt_PT |
