“…In contrast, overexpression of ANG-2 in hepatomas, gliomas, and colorectal and gastric carcinomas was found to enhance angiogenesis and augment tumor malignancy (46,(53)(54)(55)(56). Furthermore, strong correlation of ANG-2 with ANG-1 in neuroblastoma (57), gliomas (14,35), breast and prostate carcinomas (58), hepatocellular carcinoma (59), non -small cell lung carcinomas (60,61), and gastric adenocarcinoma (62) has been associated with aggressive tumor growth.…”
