| Research Abstract |
The objective of the present study was to investigate the mechanism of ANP in the prevention of cancer metastasis. In the B16/F10 hematogenous metastasis model, administration of ANP notably inhibited metastasis in the lung compared to the control mice. Furthermore, lung metastasis significantly increased in the vascular endothelial cell specific GC-A knock-out mice, and decreased in the vascular endothelial cell specific GC-A overexpression mice compared to the wild-type mice. These studies indicate that ANP/GC-A signaling in the vascular endothelial cells plays crucial roles in the inhibition of cancer metastasis. We found that ANP inhibits cancer metastasis through GC-A receptor in the vascular endothelial cells. Our data provide novel insights into the prophylactic therapy for various kinds of cancer metastasis.
