The type I insulin-like growth factor receptor (IGF-IR) and its associated signaling system play a significant role in tumorigenesis, tumor survival and progression, and cancer therapeutic resistance, and thus has provoked great interest as a promising target for cancer treatment. In this report we present the role of IGF-IR in gastrointestinal carcinomas whose pathology has been identified as tightly correlated with an abnormal expression and activation of IGF-IR. Reported data from experimental studies suggest the feasibility of targeted IGF-IR therapy in gastrointestinal carcinomas. Many types of inhibitors against IGF-IR have been developed. Inhibitors with anti-IGF-IR monoclonal antibodies and tyrosine kinase inhibitors currently undergoing preclinical and clinical evolution are also reviewed.
I型胰岛素样生长因子受体(IGF-IR)及其相关信号系统在肿瘤发生、肿瘤存活与进展以及癌症治疗耐药性中发挥着重要作用,因此作为一个有前景的癌症治疗靶点引发了极大关注。在本报告中,我们阐述了IGF-IR在胃肠道癌中的作用,其病理学已被确定与IGF-IR的异常表达和激活密切相关。来自实验研究的报道数据表明在胃肠道癌中进行靶向IGF-IR治疗具有可行性。已经研发出多种针对IGF-IR的抑制剂。本文还综述了目前正在进行临床前和临床研究的抗IGF-IR单克隆抗体和酪氨酸激酶抑制剂类抑制剂。
