Two-dimensional electrophoresis analysis of differential protein expression in squamous carcinoma of the cervix

Objective： To establish and optimize the two-dimensional gel electrophoresis （2-DE） maps of squamous carcinoma of the cervix and to study the protein difference between squamous carcinoma of the cervix （SCC） and normal cervical tissue. Methods： Using Two-dimensional gel electrophoresis followed by computer-assisted image analysis, the differential proteins between squamous carcinoma of the cervical tissue and normal cervical tissue were compared. Then using matrix-assisted laser desorption/ionization-time of flight mass spectrometry, the differential proteins were identified. Results： The well-resolved and reproducible two-dimensional gel electrophoresis patterns of squamous carcinoma of the cervix tissue and normal cervical tissue were obtained. After silver staining, the average matching ratio of squamous carcinoma of the cervix was 86.1%. There was a good reproducibility of spot position in 2-DE map, with average deviation in IEF direction of 0.95±0.13 mm, while in SDS-PAGE direction it was 1.20±0.18 mm. Ten protein spots were identified by mass spectrometry, some of which were involved in cell proliferation, cell apoptosis, intracellular enzymes, structural proteins, cycle regulation, and tumor occurrence. Conclusion： The differentially expressed proteins provide a fundamental basis for further study of human squamous carcinoma of the cervix and screening of its specific markers.     

Effects of Imbalance of Apoptosis and Proliferation on Large Bowel Carcinogenesis in Mice

OBJECTIVE To observe the pattern of changes in the proliferation and apoptosis at different stages of large bowel carcinoma in mice, and to explore the effects of the imbalance of apoptosis and proliferation at different stages of large-intestine carcinogenesis.METHODS An experimental animal model for large intestine carcinogenesis of KUNMING-strain mice was used. The carcinomas were induced by subcuteneous injection of dimethylhydrazine (DMH) and the distribution and density changes of proliferating and apoptotic cells observed through multistages toward cancer formation. The animals were killed in groups at the 12th, 18th, 24th,and 32nd weeks of carcinoma induction. The apoptotic and proliferating cells were labeled separately using TUNEL and PCNA immunohistochemical staining methodsRF, RESULTS In the normal mouse mucosa, all the apoptotic cells were situated in the superficial layers, however, the proliferating cells were situated in the basement layers, and the amount of both were small. In the early stage of carcinoma induction, the proliferation and the apoptotic cells slightly increased in amount, but there were no obvious changes in their ratio. In the medium stage, the densities of both distinctly increased, but there were no obvious changes in the ratio. In the late stage, the densities of the proliferating and the apoptotic cells in the non-carcinoma mucosa were higher than those at other stages. The proliferating cells in the dysplastic mucosa increased progressively with the increasing degree of the lesions. Although the apoptotic cells increased, their changes did not occur with the degree of the lesions. Their ratio showed a decreasing tendency with the degree of the lesions.CONCLUSIONS (①The presence of an imbalance between cell proliferation and apoptosis was confirmed in the course of large intestine carcinogenesis in a mouse model. ②In the early stage of carcinoma induction both proliferation and apoptosis were at a low level; in the medium stage, they were both at a high level; and in the late stage (that is in carcinoma), proliferation was at a very high level, while apoptosis was at a low level. ③The proliferating cells increased progressively with the degree of dysplasia. There were no obvious changes in the apoptotic cells and their ratio to the proliferating cell sshowed a progressively increasing tendency. ④In the stage of cancer formation, the most essential change was the excessive decrease in the ratio of apoptosis to proliferation. These results support the hypothesis of “Cell Selective Proliferation“, which was raised by authors previously in a study on human large bowel carcinoma.

Abstract：

Objective To study the expression and clinical significance of Survivin and PTEN in cervical carcinoma. Methods The expression of Survivin and PTEN in 60 cases of cervical carcinoma, 15 cases of CIN Ⅰ , 15 cases of CIN Ⅱ, 15 cases of CIN Ⅲ and 15 cases of normal cervical tissues were detected by immunohistochemical staining. Results The expression positive rates of Survivin were 86.67 %, 80.00 %,33.33 %, 20.00 % and 0, respectively, and those of PTEN were 21.67 %, 40.00 %, 80.00 %, 86.67 % and 100.00 % in cervical carcinoma, CIN Ⅲ, CIN Ⅱ, CIN Ⅰ and normal cervical tissues, respectively. The expression positive rates of Survivin were increased along with normal cervical epithelium, CIN Ⅰ, CIN Ⅱ,CIN Ⅲ and invasive carcinoma of cervix;while those of PTEN were inverse order.Compared with the expression positive rates of Survivin and PTEN protein in the CIN Ⅱ group, those in the CIN Ⅲ group had significant differences (P <0.01 and P <0.05, respectively). Expressions of Survivin and PTEN were correlated to the size of focus(P <0.05), the depth of tumor and pelvic lymphnode metastasis (P <0.05), but not to clinical staging, pathological types, pathological grading and age(P >0.05). There was a negative correlation between the expression of PTEN and Survivin in cervical carcinoma. Conclusion The expressions of Survivin and PTEN are correlated with invasion and metastasis of cervical carcinoma, and be related to clinical pathotology.Survivin and PTEN may play a important role in the formation, proliferation, differentuation and metastasis of cervical carcinoma. They may be used as markers of early diagnose, efficacy and prognosis evaluation.

食管黏膜癌变过程中组织细胞增殖、凋亡和p53表达的变化

目的探讨食管黏膜癌变过程中增殖、凋亡和p53表达的变化及临床意义。方法对连续胃镜检查对象818例进行食管黏膜活检和病理组织学检查,并应用TUNEL法检测凋亡指数、免疫组织化学法检测增殖指数和p53表达。结果818例食管活检组织中,正常上皮694例,单纯增生39例,轻中度异型增生24例,食管鳞癌61例。在正常上皮→单纯增生→轻中度异型增生→鳞癌中,随分化程度的进展,凋亡指数（AI）等级逐渐降低,增殖指数（PI）等级和p53表达等级则逐渐增高,差异均有统计学意义。正常上皮中AI等级与PI和p53表达等级呈负相关,PI等级与p53表达等级呈正相关。单纯增生中AI等级与p53表达等级呈负相关,PI等级与p53表达等级呈正相关。轻中度异型增生和鳞癌中AI等级、PI等级及p53表达等级之间彼此均无相关性。结论AI等级降低,PI和p53表达等级升高是食管黏膜肿瘤性生长的特征,各病理类型本身凋亡增殖和p53表达的彼此相关性可能是制约或促进癌变的机制,这些变化可以作为食管上皮恶性变倾向的参考指标。     

细胞凋亡和Rb基因在宫颈癌组织中的表达及意义

采用免疫组化法和ＤＮＡ缺口末端标记法观察Ｒｂ抑癌蛋白、增殖细胞核抗原（ＰＣＮＡ）和凋亡细胞在宫颈癌变过程中的表达。结果发现Ｒｂ抑癌蛋白在正常宫颈上皮和不典型增生上皮均全部阳性表达，在宫颈癌组织中阳性率为５７．７％，Ｒｂ基因突变随临床分期升高而递增，Ｒｂ阳性组的凋亡指数（ＡＩ）和凋亡指数／增殖指数（ＡＩ／ＰＩ）与阴性组无显著差异。凋亡指数与病理分级呈负相关（Ｐ＜０．０５）。证实Ｒｂ基因突变发生在宫颈癌的晚期，推测该基因不参与宫颈癌组织中细胞凋亡的调节。ＡＩ将成为新的预后指标。     

大肠癌组织中PCNA表达和细胞凋亡检测的临床意义

目的：探讨大肠癌组织中细胞凋亡和增殖细胞核抗原（PCNA）表达的临床意义。方法：应用免疫组化S－P法及TUNEL法对10例正常大肠黏膜和62例大肠癌组织中细胞增殖指数（PI）及凋亡指数（AI）进行检测，分析其与临床病理因素的关系。结果：在正常大肠黏膜和大肠癌组织中，PI逐渐增加，AI逐渐下降，两者比较有非常显著性差异（P＜0．01），随着大肠癌Dukes分期升高，PI逐渐增加，AI逐渐下降；与癌组织分化程度和淋巴结转移有关（P＜0．01），对这2种指标进行综合分析显示，PI增高而AI降低组，较其它异常结合模式组更易发生淋巴结转移。结论：细胞增殖与凋亡平衡失调的程度与大肠癌恶性程度密切相关，PI增高同时有AI降低者更易发生淋巴结转移，两者联合检测对大肠癌的临床分析及预后评价有重要意义。

Apoptosis in transitional cell carcinoma of bladder and its relation to proliferation and expression of P53 and Bcl-2

Transitional cell carcinoma of bladder (TCC) is a relatively common cancer among men. Tumor progression is associated with expression or modulation of several gene products that control apoptosis and proliferation. Apoptosis is a negative growth regulatory mechanism in tumors. The aim of this study is to examine apoptosis and related regulatory molecular markers in a group of patients with TCC. Paraffinembedded tissues from 49 patients with TCC were examined for the expression of bcl-2, p53 and Ki-67 by immunohistochemistry. Apoptosis was detected by TUNEL method. Correlation between apoptotic index (AI), proliferation index (PI) and bcl-2 and p53 expression with each other and with pathological grade was determined. Apoptosis was observed in 28.1% of TCC cases. The mean AI of all cases was 13.7+/-24. No correlation was found between apoptosis and differentiation status of carcinoma. Bcl-2 expression was weakly detected in only one sample. P53 expression was detected in 26 of cases with mean staining index of 102+/-96. A significant correlation between p53 and Ki-67 staining indices was observed (r=0.521, p=0.001). Both p53 and Ki-67 expression showed a good association with the pathological grade (p=0.0001 and p=0.004, respectively). None of the markers showed significant correlation with AI and no correlation was found between the ratio of AI to PI and other parameters either. In conclusion, the frequency of apoptosis in TCC of bladder appears not to be associated with tumor grade, and with bcl-2, p53 and Ki-67 expression.
