血小板反应蛋白(THBS)2作为THBS家族的一员，在多种肿瘤细胞中表达，且在肿瘤的发展及转移中具有重要意义。近年来，研究报道THBS2在不同肿瘤中的具体作用不同，并参与多种生物学过程，如细胞凋亡、伤口愈合、血管生成和炎症反应。目前THBS2在肿瘤发生发展及预后中的作用尚未完全明确，探讨THBS2在肿瘤中的异常表达及作用机制有望为肿瘤的诊断和治疗提供新的方法。“,”Thrombospondin (THBS) 2, as a member of the THBS family, is expressed in a variety of tumor cells and has important significance in the development and metastasis of tumors. In recent years, studies have reported that the specific role of THBS2 in different tumors is different, and it participates in a variety of biological processes, such as cell apoptosis, wound healing, angiogenesis and inflammation. At present, the role of THBS2 in tumorigenesis, development, and prognosis is not completely clear. Exploring the abnormal expression and mechanism of THBS2 in tumors is expected to provide a new method for tumor diagnosis and treatment.
