Abstract 

To investigate the expression levels of S100A4 in human colorectal carcinoma (CC) and its relationship with clinicopathological parameters and metastatic potential, 73 pathological specimens from patients with CC were examined for S100A4 expression by RT-PCR and immunohistochemistry. An increase of S100A4 mRNA was observed in 19/23 (82.6%) CC specimens, and S100A4 was up-regulated in 40/73 (54.7%) CC cases compared with non-neoplastic mucosal tissues. Upregulation of S100A4 was significantly related to invasion, nodal status, distant metastasis and p53 expression. Next, we investigated whether S100A4 could affect p53 transactivation and stability. Interestingly, it was revealed that treatment with exogenous S100A4 protein reduced transcriptional activity of p53 and abrogated the modification of calcium binding affinity of S100A4 protein. These findings suggested that S100A4 might be involved in the progression and metastasis of human CC, presumably via modulation of the wild-type p53 protein.
