Objective: To study the expression of the B-myb and cyclin D1 in human hepatocellular carcinoma (HCC) tissue and explore their correlation with initiation and progression of HCC. Methods: The expressions of B-myb and cyclin D1 in 60 cases of HCC tissue and the corresponding pericancerous liver tissue were detected by immunohistochemical method. Results: The positive rates of B-myb and cyclin D1 in the HCC tissue were higher than those in the pericancerous liver tissue (56.67% vs 36.67% and 50% vs 31.67%, P < 0.05) respectively. The expression of B-myb in the HCC tissue significantly correlated with the clinical stage, the extrahepatic metastasis, post-operative recurrence, and the number of tumor nodes but not correlated with the tumor thrombus in portal vein, the tumor diameter, the serum level of alpha-fetoprotein (AFP), and tumor differentiation. The expression of cyclin D1 in the HCC tissue was significantly associated with the clinical stage, the tumor thrombus in portal vein, extrahepatic metastasis, post-operative recurrence, the number of tumor nodes, and the differentiation of tumor but not associated with the tumor diameter and the serum level of AFP. The expression of B-myb had positive correlation with expression of cyclin D1 in HCC tissues. Conclusion: The overexpressions of B-myb and cyclin D1 in HCC tissue may contribute to the proliferation of hepatoma cells, and have close correlation with the initiation and progression of HCC.

Objective To investigate the pathological significance of DEK-AP-2α interaction in HER2 overexpres-sion and breast tumorigenesis. Methods The protein level of DEK,AP-2α and HER-2 in breast tumor tissues was detected by Western blot. The interaction of DEK and AP-2α in MDA-MB-453 mammary cancer cells was detected by immuno-coprecipitation. Furthermore the impact of DEK and AP-2α on HER2 expression was investigated by siRNA in MDA-MB-453 mammary cancer cells followed by semi-quantitive RT-PCR and Western blot. Results A correlation between DEK, AP-2α and HER2 levels in breast cancer tissues were found. The interaction between DEK and AP-2α in MDA-MB-453 cells was verified by co-immunoprecipitation assay. Depletion of DEK and AP-2α in MDA-MB-453 cell by siRNA cooperatively repressed HER2 expression at both the mRNA and protein levels. Conclusion Oncogene DEK has synergestic effect with AP-2α transcriptional factor to promote HER2 overexpres-sion in breast cancer.

Objective To study the expression of Oct4 gene, an embryonic stem cell marker, in cervical carcinoma cell lines and tissues for the purpose of finding the relationship between this gene and cervical cancer. Methods The expression of Oct4 in normal cervical tissues and cervical carcinoma tissue and cell lines was detected by the immunohistochemistry and RT-PCR. Results ① The expression of Oct4 mRNA in cervical carcinomas (73.3%, 22/30) was significantly higher (P<0.01) than that in normal cervical tissues (25%, 3/12); ② The rate of Oct4 protein expression in cervical cancer (53.7%, 22/41) was higher (P<0.01) than that in normal cervical tissues (7.7%, 1/13); ③ Oct4 protein was expressed in cervical carcinoma cell lines and primary tumorspheres. ④ The expression of Oct4 in tumorspheres was down-regulated during cell differentiation. Conclusion Our results imply that Oct4 may be one of the cervical cancer stem cell markers, but this still needs further research data to support.
