DARA treatment reduces tumor growth in a mouse model. DARA suppresses tumor growth in PEL xenograft mice. 107 BCBL-1 cells were subcutaneously injected into both flanks of mice (6 mice per group, in total 12 nodules). Three days after cell transplantation, 100 μg of DARA/mouse was intraperitoneally injected into the mice twice per week. The tumor size and morphology are shown in A. Tumor volumes were monitored B and weighed C. The data are presented as mean values ± standard deviation (SD). *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
