【摘要】 目的 :观察细胞周围调节蛋白 (Cyclin)D1 在宫颈癌组织中的表达并探讨其意义。方法 :应用SP免疫组化法检测 11例正常宫颈上皮 ,9例宫颈上皮内瘤样病变 (CIN)和 4 8例宫颈癌石蜡包埋组织切片中CyclinD1 基因蛋白表达情况。结果 :正常宫颈上皮、CIN和宫颈癌组织 ,CyclinD1 表达的阳性率分别为 9 0 9%、33 33%、4 1 6 7% ;从正常宫颈到CIN到宫颈癌组织中CyclinD1 表达呈现逐渐升高的趋势。宫颈癌组织CyclinD1 表达明显高于正常宫颈上皮 (P <0 0 5) ,CIN和正常宫颈上皮比较 ,CyclinD1 表达无显著性差异 (P >0 0 5)。CyclinD1 表达与宫颈癌的临床分期、组织类型、分化程度以及淋巴结转移均无显著相关性 (P >0 0 5)。结论 :CyclinD1 基因蛋白高表达可能参与宫颈癌的癌变过程更多还原

【Abstract】 Objective: This study was to elucidate the expression of cells regulato r Cyclin D 1 in normal cervix, CIN, and its implication in the genesis of cervi cal carcinoma Methods: Immunohistochemical method was used to deter mine the Cyclin D 1 expression level in 11 paraffin sections in normal cervix, 9 in CIN, and 48 in cervical carcinoma Results: The positive rate of Cyclin D 1 e xpre ssion was 9 09% of normal cervix, 33 33% of CIN , and 41 67% of cervical carc ino ma, respectively Cyclin D 1 expression increased gradually from 9 09% in the norm al cervix to 41 67% in cervical carcinoma Cyclin D 1 expression in cervical c arcin oma was significantly higher than that in normal cervix No statistical correla t ion was observed between Cyclin D 1 expression and other clinical data in patie nts with cervical carcinoma Conclusion: These data suggested that t h e Cyclin D 1 expression was involved in the carcinogensis, development, and pro gression of cervical carcinoma更多还原
