-
摘要: 目的 探讨 p2 1 WAF1/ CIP1在肺癌中的生物学功能。方法 用免疫组化法检测 62例肺癌和 1 4例正常肺组织石蜡切片 p2 1 WAF1/ CIP1的染色强度。结果 1 .p2 1 WAF1/ CIP1定位于细胞核或细胞浆。2 .小细胞肺癌与非小细胞肺癌中核 p2 1 WAF1/ CIP1表达存在显著性差异 ( P<0 .0 0 5), 浆 P2 1 WAF1/ CIP1则不存在显著性差异 P<0 .0 0 5)。3.核与浆 P2 1 WAF1/ CIP1表达的对比在高、低分化肺癌中具有显著性差异 P<0 .0 5)。结论 肺癌细胞 p2 1 WAF1/ CIP1的生物学功能可能依其定位、量表达的高低及组织学类型的不同而存在差异.Abstract: Objective To explore the biological function of p21 WAF1/CIP1 in the lung cancer. Methods p21 WAF1/CIP1 expression was immunohistochemically analyzed in paraffin embeded sample from 76 patients with surgically resected and fiberoptic bronchoscopy biopsy lung diseases,including 62 lung cancer samples and 14 normal lung tissue samples. Results 1.p21 WAF1/CIP1 was located either in the cell nuclear or in the cell plasma.2. Not plasma but nuclear p21 WAF1/CIP1 expression was significantly differe...
