摘要
胰岛素样生长因子(IGFs)是一种体内平衡调节因子,参与全身多种生理、合成和代谢过程,在促进生长中起着关键的自分泌、旁分泌和内分泌作用,涉及多种组织器官内细胞增殖、分化和凋亡的调节。大量体内、体外实验及临床报道发现IGFs分子的异常表达在各种呼吸系统、消化道恶性肿瘤、生殖系统肿瘤及其他肿瘤的增殖侵袭过程中都起到十分重要的作用。从临床角度来看,异常表达的IGF信号轴分子可被认定为癌症的诊断标志物、预后因素和现代抗肿瘤治疗的靶点。因此,针对不同肿瘤组织中IGFs变化所引发的下游分子及信号通路改变,配合靶向分子抑制剂进行针对性用药,可能成为治疗癌症的新方式。总结了IGFs信号轴在正常人体与癌症组织发展中的变化,并对IGFs信号轴的小分子抑制剂进行归纳,希望能为以后的癌症临床治疗与研究提供借鉴,为未来分子靶向治疗辅助癌症用药提供一定的参考。
Insulin-like growth factors(IGFs)are homeostasis regulatory factors that participate in diverse physiological,synthetic and metabolic processes throughout the body and play key autocrine,paracrine and endocrine roles in promoting growth,involving the regulation of cell proliferation,differentiation and apoptosis in various tissues and organs.Numerousin vivo and in vitro experiments and clinical reports have found that the abnormal expression of IGF molecules plays a crucial role in the proliferation and invasion of various organ cancers,reproductive system cancers and other tumors.From a clinical perspective,IGF signaling axis can be recognized as potential biomarkers in diagnosis,prognosis,and therapy for cancer.Therefore,targeting the downstream molecular and signaling pathway changes caused by IGFs in different cancer tissues,combined with targeted molecular inhibitors for targeted drug use,may become a new way to treat cancer.Here,we summarize the changes of IGFs signaling in different tumor tissues,and include the small molecule inhibitors of IGFs axis.This review aims to provide guidance for future clinical treatment and research of cancer to a certain extent,and to provide some reference for the use of molecular targeted therapy as an adjunct to cancer drugs in the future.
