Abstract

Tumor angiogenesis is closely associated with clinical staging and has been proposed to correlate with clinical response in terms of subsequent metastases following primary resection. Netrin-4 (NT-4) regulates angiogenic responses. Therefore, we sought to examine the effects of NT-4 on the primary tumor growth of colon cancer cells, liver and lung metastases of colon cancer cells, and responses following primary tumor resection. We used 3 different mouse models of orthotopic primary tumor and liver and lung metastases, comparing 2 human colon cancer cells lines: wild-type (low expression of NT-4) and NT-4 (overexpression of NT-4) LS174 cells. NT-4 overexpression inhibited the primary tumor growth of colorectal LS174 xenografts in nude mice (144.3±12.9 vs. 62.4±4.5 mm3; p<0.0001) as well as its related local and systemic recurrence (38 vs. 0%; p<0.01). NT-4 overexpression also markedly decreased colorectal cancer progression in terms of tumor number and volume of liver metastases in the NT-4 group of the orthotopic liver metastasis model (25 vs. 90% and 4±1 vs. 709±190 mm3, p<0.001 and p<0.05). Collectively, our findings indicate that NT-4 overexpression decreases colorectal lung metastasis and its associated lymph node involvement. NT-4 overexpression decreases tumor recurrence and metastasis after surgical resection, likely via an anti-angiogenic effect. These observations suggest that NT-4 may hold therapeutic potential in the treatment of colorectal cancer growth and major metastatic sites.
