Anti-Cancer Activity of Methanol Extracts of Cichorium Intybus on Human Breast Cancer SKBR3 Cell Line

Background: Breast cancer is the most prevalent cancer and the second cause of death among women around the world. In many cancers, including breast cancer, Fatty acid synthase (FASN) gene expression is increased significantly. In breast cancer cell lines, expression of FASN is higher in HER2 positive cell line like SKBR3 than the others. FASN is the key enzyme for fatty acid synthesis de novo pathway and it is producing palmitate which is necessary for cell membrane formation. Cichorium intybus is a medicinal plant that effectively leads to inhibition of fatty acid synthase and thus reduces the percentage of survival of cancer cell lines. Objectives: The aim of this study was to evaluate the effect of methanol extract of Chicorium intybus root on percentage of survival in SKBR3 cell line. Methods: Human breast cancer SKBR3 cell line was cultured in DMEM medium. Methanol extract of Cichorium intybus root was extracted and different dilutions (200, 300, 400, 500 and 600μg/mL) were added to cell culture. Cell viability was quantitated by MTT assay after 24, 48 and 72 hours. Results: Cichorium intybus could decrease cell viability. The effects of extract on cell viability were observed after 24, 48 and 72 hours on SKBR3 cell line and IC50 was 800, 400 and 300 after 24, 48 and 72 hours of treatment, respectively. Conclusions: Our study shows that methanol extract of Cichorium intybus has cytotoxic effects on tumor cells. This is a pilot work for further evaluation in the future.
