Abstract

Metastasis is a multistep process that involves alterations in a tumour cell's invasion, motility and adhesive capabilities. This study examined the effect of EGF on the in vitro invasion, motility and adhesion of the primary renal adenocarcinoma cell line, A704. Stimulation of the tumour cells by EGF (40 ng/ml) for a period of 24 h increased the in vitro invasion (P = 0.040) and motility (P = 0.039). Cell adhesion was examined on fibronectin, laminin, collagen IV and a 1:1:1 mix of the three extracellular matrix components. After EGF (40 ng/ml) stimulation, adhesion was,significantly decreased on fibronectin (P = 0.022) and collagen type IV (P = 0.026), but increased on the 1:1:1 mix of extracellular matrix components (P = 0.022). The 92 kDa matrix metalloproteinase (MMP-9) present in the cell-conditioned medium was also increased after a 24 h stimulation with EGF (40 ng/ml) when measured. Hence, EGF can modulate the in vitro invasion, motility, adhesiveness and matrix metalloproteinase production in the A704 cell line, and subsequently may have a role in the metastatic potential of some renal carcinomas.
