In this study, we used immunohistochemistry, single strand confirmation polymorphism (SSCP) and direct sequencing methods to analyze the mutation and protein expressions of both CTNNB1 and AXIN1 in cervical cancer.
Our findings indicate that alterations of beta-catenin are frequent in these tumors and suggest that they may play an important role in the development of cancer of the uterine cervix.
These suggest that overexpressions of MMP-2 and MT1-MMP, loss of TIMP-2 expression, and up-regulation of beta-catenin by AAC-11 transfection may contribute to the development of cervical cancer invasion.
Several mRNAs, such as those encoding guanine nucleotide-binding protein Gs (alpha subunit), leukocyte adhesion protein (LFA1-beta), nuclear factor NF45, homeobox protein Hox-A1, and beta-catenin were detected in increased levels in cervical cancer.
