Abstract

The transcriptional coactivator with the PDZ-binding motif (TAZ) has been associated with different types of cancer. In this study, we examined the TAZ protein expression and cellular localization in 194 cases of human cervical squamous cell carcinoma (SCC). We observed that a normal cervix is characterized by higher expression levels of both nuclear and cytosolic TAZ compared to cervical SCC. Lower membranous and cytosolic TAZ expression levels are associated with lymph node involvement. We observed that TAZ expression levels are associated with β1 integrin and Src in SCC and cell lines derived from human cervical cancers. Of note, knock down of TAZ increased the expression of β1 integrin and Src in both normal and human cervical cancer cells. Our data indicate that the expression and cellular localization of TAZ are inversely associated with the development and progression of cervical SCC, and TAZ-mediated transcription may be involved in the activation of the integrin-Src signalling pathway.
