    Abstract: Disclosed herein are methods of treating cancer in a subject, and methods for inhibiting growth, migration and/or invasion of a cancer cell in the subject, comprising administering to the subject a therapeutically effective amount of an antibody or antigen binding fragment thereof that downmodulates Fzd2. The antibody may specifically bind Fzd2, and may promote internalization of the Fzd2 receptor by the cancer cells and/or prevent ligand binding to Fzd2. Specific antibodies, and also specific portions of the Fzd2 molecule for antibody binding are disclosed. In one embodiment the antibody specifically binds to the epitope HGAEQICVGQNHSEDGAPAL (SEQ ID NO: 1). Specific cancers (e.g. late stage hepatocellular carcinoma), intended for treatment are provided, and include cancers that exhibit overexpression of Fzd2, and/or Wnt5a.

    Abstract translation: 本文公开了治疗受试者的癌症的方法以及用于抑制受试者中癌细胞的生长,迁移和/或侵袭的方法,包括向受试者施用治疗有效量的下调Fzd2的抗体或其抗原结合片段 。 抗体可以特异性结合Fzd2,并且可以促进癌细胞对Fzd2受体的内化和/或阻止配体结合Fzd2。 公开了特异性抗体以及用于抗体结合的Fzd2分子的特定部分。 在一个实施方案中,抗体特异性结合表位HGAEQICVGQNHSEDGAPAL(SEQ ID NO:1)。 提供旨在治疗的特异性癌症(例如晚期肝细胞癌),包括表现出过度表达Fzd2和/或Wnt5a的癌症。
