Kaempferol inhibits the proliferation and migration of Epstein-Barr virus-positive diffuse large B-cell lymphoma cells

Abstract

Purpose: To assess the effect of kaempferol on the growth, apoptosis, and motility of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) cells, and to elucidate its mechanism of action. Methods: Human DLBCL cells were used to generate EBV-positive (EBV +) cell line Pfeiffer. CCK-8, colony formation, flow cytometry (FCM), and immunoblot assays were employed to determine the effects of kaempferol on the growth and apoptosis of EBV + DLBCL cells. Cell motility was evaluated by Transwell and immunoblot assays. Immunoblot assay was further conducted to unravel the mechanism of action. Results: Kaempferol inhibited the growth of EBV + DLBCL cells. It also enhanced the apoptosis of EBV + DLBCL cells, but inhibited the motility of the cells. Furthermore, kaempferol inhibited PI3K/AKT axis, thereby suppressing DLBCL. Conclusion: Kaempferol inhibits the growth and motility of EBV + DLBCL cells via PI3K/AKT axis. It is therefore a potential drug for the treatment of DLBCL.
