Background:
Mucin-1, is a membrane-bound protein that is a member of the mucin family. Mucins are O-glycosylated proteins that play an essential role in forming protective mucous barriers on epithelial surfaces. These proteins also play a role in intracellular signaling. This protein is expressed on the apical surface of epithelial cells that line the mucosal surfaces of many different tissues including lung, breast stomach and pancreas. MUC-1 exclusively located in the apical domain of the plasma membrane of highly polarized epithelial cells. MUC-1 can act both as an adhesion and an anti-adhesion protein. This protein may provide a protective layer on epithelial cells against bacterial and enzyme attack. MUC-1 participated in modulates signaling in ERK, SRC and NF-kappa-B pathways. In activated T-cells, MUC-1 influences directly or indirectly the Ras/MAPK pathway. MUC-1 promotes tumor progression and regulates TP53-mediated transcription and determines cell fate in the genotoxic stress response.

文献和实验、肝细胞癌、肺癌、乳癌以及甲状腺髓质癌的临床监测，亦见于绒毛膜癌、骨癌、前列腺癌和卵巢癌，但无早期诊断价值。 此外，CEA轻度增加也见于某些良性消化道疾病如肠梗阻、胆道梗阻、胰腺炎、肝硬化、结肠息肉、溃疡性结肠炎以及吸烟者和老年人。这些消化道良性疾病患者中25%的人血清CEA可暂时性升高。 癌抗原50（CA50） 正常范围：放射免疫法 小于23000U／L。 检查介绍：癌抗原50是一种以唾液酸酯和唾液酸糖蛋白为主的肿瘤标志物
着肿瘤，以往也称癌抗原。正常细胞膜表面都有丰富的糖蛋白，当正常细胞转化为恶性细胞时，细胞表面的糖蛋白发生变异，形成了一种和正常细胞不同的特殊抗原，通常存在于肿瘤细胞表面或由肿瘤细胞分泌。 包括内容： 1.CA125 2.CA19-9 3.CA15-3 三、酶类肿瘤标志物 大多数酶存在于细胞中，由于肿瘤细胞破坏或细胞膜通透性改变，酶释放至血液中；肿瘤细胞代谢异常，使某些酶或同工酶的合成增加；肿瘤组织的压迫和浸润，导致某些酶的排泄
（CA125） CA125存在于上皮卵巢癌组织和病人血清中，是研究最多的卵巢癌标记物，在早期筛查、诊断、治疗及预后的应用研究均有重要意义。CA125对卵巢上皮癌 的敏感性可达约70%。其他非卵巢恶性肿瘤（宫颈癌、宫体癌、子宫内膜癌、胰腺癌、肺癌、胃癌、结/直肠癌、乳腺癌）也有一定的阳性率。良性妇科病（盆腔 炎、卵巢囊肿等）和早期妊娠可出现不同程度的血清CA125含量升高。 4、癌抗原15-3（CA15-3） CA15-3可作为乳腺癌辅助诊断，术后随访和转移复发的指标。对早期乳腺癌的敏感
