Abstract

Plantamajoside (PMS) has been shown to have anticancer effects and is the main compound of Plantago asiatica. The aim of the present study was to investigate the effects of PMS on malignant melanoma and its molecular mechanisms. The malignant melanoma cell line A2058 was treated with different concentrations of PMS (0, 20, 80 and 160 µg/ml) for 24, 48 or 72 h, followed by cell viability detection using the Cell Counting Kit‑8 assay. The present results suggested that PMS inhibited cell viability in a dose‑dependent manner. In addition, flow cytometry was used to analyze cell apoptosis, and Transwell assays were used to investigate cell migration and invasion. The present results suggested that PMS induced A2058 cell apoptosis, and inhibited cell invasion and migration in a dose‑dependent manner. In order to study the molecular mechanism by which PMS inhibited malignant melanoma growth and metastasis, reverse transcription‑quantitative PCR and western blotting were used to determine the expression levels of apoptotic‑related genes and PI3K/AKT signaling pathway‑related proteins. The present results indicated that PMS inhibited the protein and mRNA expression of Bcl‑2, and promoted the expression of Bax and caspase‑3 in a dose‑dependent manner. The protein expression level of phosphorylated‑AKT was dose‑dependently reduced by PMS treatment. Collectively, the present results suggested that PMS inhibited the invasion, migration and viability of malignant melanoma cells. In addition, PMS induced apoptosis by regulating the expression levels of apoptotic‑related genes and the activation of the PI3K/AKT signaling pathway, thereby exerting anti‑malignant melanoma effects.
