Twist induces epithelial-mesenchymal transition in cervical carcinogenesis by regulating the TGF-β/Smad3 signaling pathway

Epithelial-mesenchymal transition (EMT) is associated with the metastasis and poor prognosis of cervical cancer. However, the underlying mechanisms are poorly defined. In the present study, we investigated whether Twist plays a direct role in human cervical cancer using immunohistochemical and western blot analyses. Immunohistochemical analysis revealed that Twist is highly expressed in cervical cancer, which correlates with poor tumor pathological differentiation or lymph node metastasis (P
