Abstract:

Objective

We analyze the expression of VASP in CRC, and study the role of VASP in promoting CRC metastasis.

Methods

The expression of VASP was detected by Real-time PCR and immunohistochemistry in human CRC cohort. The effect of VASP-mediated invasion and metastasis were analyzed by Transwell assays and tail veins metastasis model both in vitro and in vivo.

Results

The expression levels of VASP were dramatically higher in CRC tissues than in adjacent nontumor tissues (χ2=82.1,P<0.001). Elevated expression of VASP was positively correlated with tumor size, tumor differentiation, nerve invasion, the lymph node metastasis, distant metastasis, higher American Joint Committee on Cancer (AJCC stage) and poor prognosis in human CRC. COX analysis indicated VASP expression was independent predictor for high recurrence rate and poor overall survival. Elevated expression of VASP promotes CRC metastasis both in vitro and in vivo.

Conclusion

VASP was overexpression and correlated with poor prognosis in CRC. Upregulated VASP can promote CRC metastasis and could be served as a potential treatment marker for CRC patients.
