本发明涉及Dickkopf2(DKK2)的抑制作用增加CD8+细胞毒性T淋巴细胞(CTL)活性、减弱肿瘤血管生成，并且从而抑制肿瘤形成的发现。因此，在本文所述的各种实施方式中，本发明的方法涉及通过给患者施用有效量的DKK2基因消耗剂来治疗癌症的方法，在对象中提供抗肿瘤免疫性和抗肿瘤血管生成的方法，刺激T细胞介导的对细胞群体或组织的免疫应答和抑制对象中的肿瘤血管生成的方法。另外，本发明包括诊断癌症或发展癌症或转移的倾向的方法，以及确定免疫疗法治疗或癌症疫苗用于治疗癌症的使用的方法。此外，本发明包括用于治疗癌症的药物组合物以及用于实施上述方法的试剂盒。 The present invention relates to the discovery that inhibition of Dickkopf2 (DKK2) increases CD8+ cytotoxic T lymphocyte (CTL) activity, attenuates tumor angiogenesis, and hence suppresses tumor formation. Thus, in various embodiments described herein, the methods of the invention relate to methods of treating cancer by administering to a patient an effective amount of DKK2 gene depleting agent, methods for providing anti-tumor immunity and anti-tumor angiogenesis in a subject, methods of stimulating a T cell mediated immune response to a cell population or a tissue and suppressing tumor angiogenesis in a subject. Additionally, the current invention includes methods of diagnosing a cancer or a predisposition of developing a cancer or a
