β-elemene against Burkitt’s lymphoma via activation of PUMA mediated apoptotic pathway

Publication date: October 2018Source: Biomedicine & Pharmacotherapy, Volume 106Author(s): Tonglin Hu, Yu GaoAbstractBurkitt’s lymphoma is a type of highly aggressive Non-Hodgkin's lymphoma. Although advanced Burkitt’s lymphoma is responsive to high-intensity chemotherapy regimens, increasing systemic toxicity, tumor recurrence and metastasis significantly reduce the patient survival. Thus, it is important to investigate novel antitumor agents with safety and effectiveness. β-elemene shows anti-proliferative effect on cancer cells by triggering apoptosis through regulating several molecular signaling pathways. However, its role in the suppression of Burkitt’s lymphoma has not yet been fully elucidated. The inhibitory effect of β-elemene in Burkitt’s lymphoma was studied in vitro and in vivo, as well as the involved molecular mechanism. The results demonstrated that β-elemene effectively inhibited the growth and induced the apoptosis of Burkitt’s lymphoma cells through upregulation of PUMA expression and modulating PUMA related apoptotic signaling pathway. The in vivo data confirmed the anti-tumor effect of β-elemene in the xenografts, suggesting that β-elemene is associated with PUMA activation, leading to Bax and caspase induction and onset of mitochondrial apoptosis.Graphical abstract
