摘要：

The CCN3/nephroblastoma overexpressed gene belongs to the CCN family of genes that encode secreted proteins involved in a variety of processes including tumorigenesis. Altered expression of CCN3 has been observed in human nephroblastoma and renal cell carcinoma (RCC), suggesting that CCN3 plays a role in kidney tumorigenesis. The aim of the present study was to examine the role of CCN3 in clear cell RCC biology. In particular, we studied the expression of CCN3 in 32 pairs of RCC tissues and corresponding normal kidney tissues using immunohistochemistry. The CCN3 gene was transfected into the 786-O cell line and the behaviors of stably transfected clones were analyzed. Results showed the expression of CCN3 was lower in RCC tissues compared to corresponding normal kidney tissues and the expression of CCN3 was inversely correlated with the Ki67 index. CCN3-expressing clones exhibited significantly inhibited cell proliferation. Furthermore, CCN3-transfected 786-O cells exhibited increased adhesion to extracellular matrix proteins, migration and invasion in Matrigel. Our data indicated that CCN3 plays an anti-proliferative role in Clear cell RCC cells and promotes the adhesion, migration and invasion of clear cell RCC cells.
