    Abstract:
    We aimed to investigate the antitumor activity of wheat bran arabinoxylans, including the role of its immunostimulatory effect. In S180 tumor-bearing mice arabinoxylan administration significantly inhibited the growth of mouse transplantable tumors and remarkably promoted thymus and spleen indexes, splenocyte proliferation, natural killer cell and macrophage phagocytosis activity, interleukin 2 production, and delayed-type hypersensitivity reaction. In addition, it increased peripheral leukocyte count, and bone-marrow cellularity in tumor-bearing mice. As the antitumor activity of arabinoxylans may be mediated via the improvement in the immune response, they can be considered an antitumor agent with immunomodulatory activity.
