| Research Abstract |
The expression of CD44 variant isoforms is very low in head and neck squamous cell carcinoma although the expression level of CD44s is high. Cleavage fragment of CD44 was also detected. Moreover, immunostaining of HNSCC revealed the translocation of CD44 to nucleus. This result supports our in vitro data of the sequential cleavage of CD44 and functiuon as a signal transduction molecule.
