摘要：

With currently available treatment, patients with refractory Hodgkin lymphoma (HL) or those who relapse multiple times have an extremely poor prognosis. Therefore, new agents and novel therapeutic approaches are urgently needed. Antiapoptotic proteins such as Bcl-2 and Bcl-x have been associated with the growth and survival of Hodgkin Reed-Sternberg cells and are potential therapeutic targets. ABT-737 is a small molecule that inhibits the Bcl-2 family of apoptosis regulators. In this study, we show the concentration-dependent and time-dependent cytotoxicity of ABT-737 against cell lines derived from patients with HL. A concurrent reduction in a number of intracellular cell growth and survival related molecules, such as Bcl-2, Bcl-xl, NF-kappa B and survivin was also seen. Drug combination studies using a panel of conventional and novel therapeutic agents show that ABT-737 potentiates the activity of agents that have inherent anti-lymphoma activity and provide support for the evaluation of ABT-737 in the clinical setting.
