Abstract

Sulforaphane (SFN) is an isothiocyanate, inducing cytotoxic effects in various human cancer cells, including leukemia cells through cell cycle arrest and apoptosis. However, the effect of SFN on the immune responses in a leukemia mouse model remains to be investigated. The present study investigated whether SFN has an effect on the immune responses in a WEHI‑3‑induced leukemia mouse model in vivo. Normal BALB/c mice were injected with WEHI‑3 cells to generate the leukemia mouse model, and were subsequently treated with placebo or SFN (0, 285, 570 and 1,140 mg/kg) for 3 weeks. Following treatment, all mice were weighted and blood samples were collected. In addition, liver and spleen samples were isolated to determine cell markers, phagocytosis and natural killer (NK) cell activities, and cell proliferation was examined using flow cytometry. The results indicated that SFN treatment had no significant effect on the spleen weight, however it decreased liver and body weight. Furthermore, SFN treatment increased the percentage levels of CD3 (T cells) and CD19 (B cell maker), however had no effect on the levels of CD11b (monocytes) or Mac‑3 (macrophages), compared with the WEHI‑3 control groups. The administration of SFN increased the phagocytosis of macrophages from peripheral blood mononuclear cells and peritoneal cavity, and increased the activity of NK cells from splenocytes. Administration of SFN promoted T and B cell proliferation following stimulation with concanavalin A and lipopolysaccharide, respectively.
