Inhibitory effects of acylated blueberry anthocyanin on H22 murine tumors
To supply reference for further antitumor mechanism studies, the antitumor effect of acylated blueberry anthocyanin (ABA) was studied on H22 murine-transplanted tumor experiment. Mice treated with ABA in combination with cyclophosphamide (CTX) had 53.74% life extension rate. CTX also has significant antineoplastic effect, which could inhibit tumor growth by 63.12%. The spleen and thymus indices decreased by CTX also ameliorated considerably. The activities of alanine aminotransferase and aspartate aminotransferase were significantly lower compared with model group. Malondialdehyde, the product of lipid peroxidation was also decreased. Meanwhile, the activities of antioxidant enzymes, such as catalase, superoxide dismutase, and glutathione peroxidase, were enhanced in a dose-dependent manner (P < .05). Electron microscopy images showed that tumor cells in the mix group had a large sheet of necrosis than the other groups. ABA had strong antitumor effect on H22, as well as synergetic and attenuated toxic effect when combined with CTX.
