Extracts and components of Ficus carica leaves suppress survival, cell cycle, and migration of triple-negative breast cancer MDA-MB-231 cells.

Abstract

BackgroundProducts from Ficus carica have been used in traditional medicine to treat many diseases. This study aimed to analyze anticancer effects of extracts of F. carica leaves on the triple-negative breast cancer cell line MDA-MB-231.Materials and methodsThe human breast cancer cell line MDA-MB-231 was used to evaluate effects of F. carica extracts. Effects of F. carica on cell viability were evaluated using MTT assays. Cell-cycle distribution was examined using cell-cycle analysis. Wound-healing assays were used to evaluate migration of MDA-MB-231. Quantitative reverse-transcription polymerase chain reaction was used to detect levels of Bax, p53, p21, GATA3, ELF5, cyclin-dependent kinases, MMP2, and tissue inhibitors of metalloproteinase.ResultsWe investigated the mechanism of anti-growth effects, and found that the expressions of genes that promote apoptosis were increased. In addition, the treated cells illustrated increased portion at S phase and changed expression of cyclin-dependent kinases, demonstrating cell-cycle arrest at the S phase. Furthermore, treated cells showed decreased cell mobility, which is essential for metastasis. Two of the active components of F. carica leaves, bergapten and psoralen, had similar anticancer effects as F. carica leaf extracts, indicating that these two components might play important roles in anticancer effects of F. carica leaves.ConclusionOur findings suggest that F. carica leaves might be a good source to develop drugs for suppressing cancer-cell growth and migration to treat triple-negative breast cancers.
