IFN‑stimulated gene (ISG)20 is a key member of the ISG family, serving a central role in antiviral defense, immune regulation and cell metabolism through its exonuclease activity. ISG20 is markedly dysregulated in various malignancies, including clear cell renal cell carcinoma, glioma, breast cancer and hepatocellular carcinoma, and it is associated with tumor proliferation, metastasis, angiogenesis and immune evasion. Its dual regulatory roles, such as promoting tumor progression via the MMP9/CCND1 signaling axis or enhancing antitumor immunity by activating the IFN‑β pathway, highlight its complex involvement in tumor biology. The present review aimed to summarize the discovery, structural characteristics and physiological functions of ISG20, and its multifaceted roles in tumor development. Moreover, the potential of ISG20 as a novel biomarker, immunoadjuvant and therapeutic target is discussed, offering theoretical insight and translational directions for precision oncology.
干扰素刺激基因(ISG)20是ISG家族的关键成员,通过其核酸外切酶活性在抗病毒防御、免疫调节和细胞代谢中发挥核心作用。ISG20在包括透明细胞肾细胞癌、神经胶质瘤、乳腺癌和肝细胞癌在内的各种恶性肿瘤中明显失调,并且与肿瘤增殖、转移、血管生成和免疫逃逸有关。其双重调节作用,如通过MMP9/CCND1信号轴促进肿瘤进展或通过激活IFN-β途径增强抗肿瘤免疫力,突出了其在肿瘤生物学中的复杂参与。本综述旨在总结ISG20的发现、结构特征和生理功能,及其在肿瘤发生发展中的多方面作用。此外,还讨论了ISG20作为新型生物标志物、免疫佐剂和治疗靶点的潜力,为精准肿瘤学提供理论见解和转化方向。
