Efficacy of an angiogenesis inhibitor, TNP-470, in xenotransplanted human colorectal cancer with high metastatic potential

Abstract

p53 mutation is thought to enhance angiogenesis, favoring the growth of the hepatic metastases. TNP-470 proved the excellent antimetastatic effect of TK-4 on hepatic metastases. TK-4 has the highest metastatic potential and p53 mutation. An antiproliferative effect was observed on the rapidly growing primary tumors in which angiogenesis may be dominant.
