Angiogenesis in liver metastasis of colo-rectal carcinoma
In liver metastasis of color-rectal carcinoma, angiogenesis is supported by vascular endothelial growth factor (VEGF) and E-selectin while it is suppressed by Netrin-4 and LK-68. Sinusoidal endothelial cells and the hepatocyte-derived extracellular matrix support growth of microvessels in liver metastases of color-rectal cancers. Based on these insights, the new treatment for liver metastasis of color-rectal cancers target diverse pathways and molecules of angiogenesis, especially the VEGF pathway. Additional agents target the cyclooxygenase-2 pathway or follow regimens for inhibiting angiogenesis. In this review, we discuss angiogenesis and treatments avaiable for color-rectal liver metastasis.
