  • EXPRESSION OF BCL-2 AND P16 PROTEIN AND THEIR SIGNIFICANCE IN GALLBLADDER BENIGN AND MALIGNANT LESION

    The expression of bcl-2 and p16 in 25 cases of gallbladder mucosa hyperplasia, 40 cases of gallbladder carcinoma and 25 adjacent normal gallbladder mucosa tissue was detected with immunohistochemical staining. Normal gallbladder mucosa was uniformly negative. Bcl-2 and p16 positive rate were significantly higher in hyperplasia and carcinoma than in normal tissue (P<0.01). Expression of bcl-2 and p16 got higher with the increasing degree of hyperplasia, p16 was associated with lymph node metastasis and depth of invasion of carcinoma of the gallbladder. The results suggest that bcl-2 and p16 expression play an important role in tumorigenesis, p16 can be used as a prognostic index for gallbladder carcinoma.

  • Expression of Murine Double Minute Gene 2 and Multiple Tumor Suppressor P16 Gene in Colorectal Carcinoma and Its Clinical Significance

    目的 探讨鼠双微基因2(murine double mimute 2, MDM2)和多肿瘤抑制基因P16在大肠癌中的表达及临床意义。 方法 纳入2006年10月-2007年3月收治的67例大肠癌患者,另取距肿瘤10cm以上癌旁组织30例、腺瘤组织20例、正常黏膜20例作为对照。采用免疫组织化学链霉菌抗生物素蛋白-过氧化物酶(SP)法检测肠黏膜MDM2和P16基因蛋白表达。 结果 MDM2在大肠癌组织中的阳性表达率为71.6%(48/67),明显高于结肠腺瘤组织、癌旁组织和正常黏膜(Plt;0.05)。P16在大肠癌组织中的阳性表达率为38.8%(26/67),与结肠腺瘤组织75.0%,癌旁组织83.3%,正常黏膜组织90.0%比较,差异均有统计学意义(Plt;0.05)。大肠癌组织中MDM2在不同分化程度中表达差异无统计学意义(Pgt;0.05)。P16在不同分化程度中表达差异有统计学意义(Plt;0.05),MDM2和P16在不同Dukes分期中,有无淋巴结转移之间表达差异有统计学意义(Plt;0.05)。MDM2与P16基因蛋白在不同年龄组,不同性别组中,表达差异无统计学意义(Pgt;0.05)。在大肠癌中MDM2蛋白与P16蛋白表达无明显相关性(Pgt;0.05)。 结论 MDM2和P16的异常表达与大肠癌的发生、发展有关,联合检测MDM2和P16对大肠癌的临床诊断、治疗和判断预后有实际意义。

  • The Expression and Significances of Cyclind1,P16 in Cutaneous Squamous Carcinoma

    目的:观察CyclinD1,P16在皮肤鳞状细胞癌组织中的表达,探讨CyclinD1,P16在皮肤鳞状细胞癌发生发展中的作用。方法:用免疫组织化学技术检测40例皮肤鳞癌石蜡包埋组织和10例正常皮肤组织的CyclinD1,P16表达。结果:CyclinD1在皮肤鳞癌组织中表达高于皮肤正常对照组,两者差异有显著统计学意义(Plt;0.01); P16在皮肤鳞癌组织中表达低于皮肤正常对照组,但两者差异无显著统计学意义(Pgt;0.05);CyclinD1,P16在皮肤鳞癌中表达呈正相关性(r=0.782,Plt;0.01)。结论:CyclinD1在皮肤鳞状细胞癌组织中阳性表达上调,P16在皮肤鳞状细胞癌组织中阳性表达下调,CyclinD1,P16在皮肤鳞癌中表达呈正相关。
