Biochanin a induces anticancer effects in SK-Mel-28 human malignant melanoma cells via induction of apoptosis, inhibition of cell invasion and modulation of Nf‑κB and MAPK signaling pathways

Abstract

The present study aimed to investigate the antitumor activity of Biochanin A in SK-Mel-28 human malignant melanoma cells. An MTT assay was used to study the cytotoxic effects of Biochanin A. In vitro wound healing and invasion assays were used to investigate the effects on cell migration and invasion. Fluorescence microscopy using acridine orange/propidium iodide was used to study effects on cell morphology and apoptosis. Nuclear factor (NF)‑κB and mitogen-activated protein kinase (MAPK) protein expression levels were determined by western blot analysis. The results indicated that Biochanin A significantly inhibited the growth of SK-Mel-28 cells in a dose and time dependent manner. Treatment of the cells with Biochanin A induced apoptosis in a dose dependent manner. Additionally, Biochanin A led to inhibition of cell migration and invasion in a dose-dependent manner and upregulated the expression of key proteins in the NF‑κB and MAPK signaling pathways.
