The impact of NudCD1 on renal carcinoma cell proliferation, migration, and invasion.

OBJECTIVE

Renal cell carcinoma (RCC) is the most common malignant tumor in the urogenital system. Its easily metastatic characteristics greatly reduce the postoperative survival rate. NudCD1, as a proto-oncogene, may be involved in the proliferation, migration, and invasion of renal cell carcinoma cell. This study intends to explore the expression of NudCD1 in renal cancer tissue and its effect on renal cell behavior.

PATIENTS AND METHODS

NudCD1 expression in RCC tissue was tested Western blot. The cellular localization of NudCD1 was detected by immunohistochemistry (IHC). NudCD1 highly expressed RCC cell line was selected. NudCD1 knockdown or overexpression was performed through cell transfection. Cell proliferation, migration, and invasion were assessed by MTT assay, wound scratch assay, and transwell assay, respectively.

RESULTS

NudCD1 mainly located in the cytoplasm and significantly upregulated in RCC tissue compared with adjacent normal control (p < 0.05). NudCD1 expressed highest in A498 cell line among several RCC cell lines. NudCD1 expression was positively correlated with cell proliferation, migration, and invasion in A498. NudCD1 may be treated as a key factor in regulating cell behavior.

CONCLUSIONS

NudCD1 significantly increased in RCC and was positively correlated with cell proliferation, migration, and invasion. It could be used as an indicator for the early screening and potential treatment target for RCC.
