Figure Lengend Snippet: Figure 1. N-acetylcysteine and vitamin C selectively kill human B lymphoma cell lines and inhibit tumor growth in vivo (A) Viability of human B lymphoma cell lines following 48 h incubation with N-acetylcysteine (NAC; left) and vitamin C (VitC; right) as judged by PrestoBlue-based assays. (B) Number of cells remaining after incubation with NAC and VitC for 72 h. (C) Number of Ramos (left) and LY1 (right) cells remaining after incubation with lower doses of NAC, VitC, and both compounds for 48 h. (D and E) Tumor growth in NSG mice injected s.c. with 107 Ramos (left) and LY1 (right) cells. When tumors had developed, the mice were injected i.p. with PBS (Ctrl, n = 11) and higher doses of NAC (n = 7) and VitC (n = 7) (D) and lower doses of NAC (n = 13), VitC (n = 13), and both NAC and VitC (n = 7) (E) five times/week; tumors were measured three times/week. (F) Tumor growth in NSG mice engrafted subcutaneously with 107 IM9 cells. When tumors had developed, the mice were injected i.p. with PBS (Ctrl, n = 5), NAC (n = 5), and VitC (n = 5) five times/week. *p < 0.05; **p < 0.01; ***p < 0.005; ****p < 0.001.
