分子生物学研究揭示肿瘤的发生是基因多重损伤的复杂过程，癌基因的激活、抑癌基因的突变及编码产物的过度表达均可导致肿瘤细胞的恶性转化和增殖失调［1］，我们对子宫内膜癌进行P53、C－erbβ－2、PCNA的检测，以期对子宫内膜癌的发生进行探讨，并为其病理诊断取得更多的客观
Molecular biology studies reveal that tumorigenesis is a complex process of multiple gene damage. The activation of oncogenes, the mutation of tumor suppressor genes and the overexpression of the encoded products can lead to the malignant transformation and proliferation of tumor cells. [1] Endometrial cancer detection of P53, C-erbβ-2, PCNA, with a view to explore the occurrence of endometrial cancer, and pathological diagnosis to obtain more objective
