Overexpression of galectin-3 in a variety of cancer cell lines has been shown to correlate with tumor progression and metastasis. In this study, we investigated the expression of galectin-3 in clear cell renal cell carcinoma (CC-RCC) and evaluated the relationship between galectin-3 expression levels and the clinicopathological features of CC-RCC. Expression of galectin-3 in the kidney cancer cell lines Caki-1, Caki-2, A704, ACHN and KPK-1 were evaluated using western blot analysis, while galectin-3 expression in CC-RCC tissues and normal parenchyma were measured by real-time PCR and immunohistochemistry. We found that galectin-3 was overexpressed in the Caki-1, Caki2, A704, ACHN and KPK-1 cell lines and that the expression level in CC-RCC was also significantly higher than that in renal parenchyma obtained from the same patient samples (p= 0.039). Galectin-3 expression in CC-RCC with distant metastasis was also significantly higher than that in CC-RCC without distant metastasis (p= 0.045). In conclusion, we revealed that galectin-3 is highly expressed in CC-RCC, especially in CC-RCC with distant metastasis, suggesting that galectin-3 may serve as a novel target molecule for predicting CC-RCC metastasis.
