Figure 1. NB(Ni,As) inhibits mantle cell lymphoma growth.

Figure 1

18 days after inoculation with Z138C lymphoma cells, Rag2M mice were randomized and treated with weekly injections of NB(NaCl), As2O3 (4, 6, or 8 mg/kg), or NB(Ni,As) (4, 6, or 8 mg/kg). (A) Tumors treated with NB(Ni,As) were significantly smaller than those treated with NB(NaCl). **, P>0.01, ***, P>0.001. Arrows indicate treatment. (B) Weight was monitored daily during the treatment period. Injection of As2O3 was acutely toxic, whereas mice injected with NB(NaCl) showed normal weight gain. Mice injected with any dose of NB(Ni,As) lost weight, though mice treated with 4 mg/kg showed the least amount of weight loss during the treatment period.
