Abstract:

Epidemiologically, a malignancy of nasopharyngeal carcinoma (NPC) is endemic in worldwide, characterized with high invasiveness and lethality. Formononetin (FN), an anti-tumor bioactive component, is found to exert anti-proliferative activity against NPC cells. However, the invasive pharmacological activities of FN against NPC have not yet been investigated. In this study, the human NPC data and samples were used for further assays. In addition, a human cell line of CNE2 was used to evaluate the anti-invasive effects of formononetin and the underlying mechanism. As results, advanced NPC patients were diagnosed through validation of blood tumor markers and medical images, and the results showed increased Lamin A/C and cytokeratin 19 (CK19) expressions in carcinomatous sections. In experimental study in vitro, FN-treated CNE2 cells exhibited inhibited cellular proliferation, promoted cell apoptosis, and decreased would healing process, reduced cellular migratory capability, respectively. Furthermore, FN-treated CNE2 cells resulted in down-regulated expressions of b-cell lymphoma-2 (Bcl-2), extracellular regulated protein kinases1/2 (ERK1/2), Lamin A/C and CK19 in a dose-dependent manner, while intracellular Bax expression was elevated. Taken together, these clinical findings elucidate invasive characteristics of human NPC samples. Further, the anti-proliferative and invasive benefits of FN were achieved through suppression of cellular ERK1/2 pathway and inactivation of intracellular Lamin A/C signaling in NPC cells.
