胸腺素是一类具有高度遗传保守性的酸性蛋白质 ,最早从牛胸腺中提取出来 ,可分为α族和 β族两类 ,后来发现它普遍存在于人类多种组织细胞当中。胸腺素与肿瘤的关系密切 ,许多肿瘤中都有胸腺素的高表达 ,而且表达程度往往与肿瘤的良恶性、转移能力以及预后有很大关系。α族胸腺素对肿瘤的治疗有一定的作用。胸腺素在肿瘤诊断和治疗方面将有广阔的应用前景 Thymosin is a type of highly conserved acidic protein that was first extracted from bovine thymus and can be divided into two groups: α and β. It was later found that it is ubiquitous in many human tissue cells. Thymosin is closely related to tumors. Many tumors have high expression of thymosin, and the degree of expression is often related to benign and malignant tumors, metastasis ability, and prognosis. Alpha thymosin has a certain role in the treatment of tumors. Thymosin has broad application prospects in the diagnosis and treatment of tumors
