ABSTRACT
@#Cell gap junctions are a universal form of cellular connection in animal tissue that mediate the exchange of information, energy and material between adjacent cells. Clinical studies have demonstrated that the abnormal expression of the connexin 43 （Cx43） gene is closely associated with carcinogenesis and tumor progression. The present study reviewed relevant studies concerning the association between abnormal expression of Cx43 and oral squamous cell carcinoma as well as communication abnormalities of cell gap junctions.
ABSTRACT
@#HH (hedgehog) signal pathway consists the hedgehoge ligand (Shh、Ihh and Dhh), the Patch and Smo membrane protein complex and Zinc finger transcription factor Gli (Gli1, Gli2, Gli3). In HH (hedgehog) signaling pathway, Gli1 not only plays a dominant and decisive role in the zinc finger transcription factor Gli (Glioma-associated oncogene homolog) family, but also includes epithelial-mesenchymal transition (EMT) and oral squamous cell carcinoma, tumor invasion and metastasis. The research on oral squamous cell carcinoma and Shh/Gli1 signal axis is rare. In this paper, the squamous cell carcinoma of oral epithelial mesenchymal transformation and correlation study of quality Gli1 is reviewed.
