Dicer1在宮頸腫瘤組織中的表達(dá)及意義
[Abstract]:Objective: to investigate the expression and significance of Dicer1 in normal cervical epithelium, cervical intraepithelial neoplasia and cervical squamous cell carcinoma. Methods the expression of Dicer1 protein and mRNA in normal cell line (End1/E6E7), cervical carcinoma cell line (S12) and cervical carcinoma cell line (Ca Ski,He La,Si Ha and C33A) were detected by Western blot and RT-PCR. The expression of Dicer1 in normal cervix was detected by immunohistochemistry. Expression level of cervical intraepithelial neoplasia and cervical squamous cell carcinoma. Results: the expression level of Dicer1 in normal cervical epithelial cell line was lower than that in cervical carcinoma cell line. The expression of Dicer1 in normal cervix and Grade III grade cervical squamous cell carcinoma was lower with the increase of malignant degree, but was higher in (grade I grade of cervical intraepithelial neoplasia and highly differentiated cervical carcinoma. Conclusion there are differences in the expression of Dicer1 in normal cervix, cervical intraepithelial neoplasia and cervical squamous cell carcinoma, which provides a basis for further study of the role and molecular mechanism of Dicer1 in the carcinogenesis and development of cervical cancer.
