ANXA1 is a major cellular substrate of the oncogenic tyrosine kinases such as EGF receptor and hepatocyte growth factor (HGF) receptor, c-met. Previously, we have shown that expression of HGF and c-met is significantly associated with the progression of OSCC in Taiwan. Kermorgant et al. recently showed that PKC controls HGF-dependent c-met traffic, signaling and cell migration. Prior study indicate that the mitogen phorbol-12-myristate 13-acetate (PMA) induced ANXA1 nuclear translocation in a PKCdelta-dependent manner and ANXA1 nuclear translocation may participate in the regulation of cellular proliferation and the differentiation. However, it is not known whether HGF can induce ANXA1 nuclear translocation or not and how this relates to the pathogenesis of oral SCC.
