Angiogenesis and disruption of liver vascular architecture have been linked to progression to cirrhosis and liver cancer (HCC) in chronic liver diseases, which contributes both to increased hepatic vascular resistance and portal hypertension and to decreased hepatocyte perfusion. On the other hand, recent evidence shows that angiogenesis modulates the formation of portal-systemic collaterals and the increased splanchnic blood flow which are involved in the life threatening complications of cirrhosis. Finally, angiogenesis plays a key role in the growth of tumours, suggesting that interference with angiogenesis may prevent or delay the development of HCC. This review summarizes current knowledge on the molecular mechanisms of liver angiogenesis and on the consequences of angiogenesis in chronic liver disease. On the other hand, it presents the different strategies that have been used in experimental models to counteract excessive angiogenesis and its potential role in preventing transition to cirrhosis, development of portal hypertension and its consequences, and its application in the treatment of hepatocellular carcinoma.
血管生成和肝脏血管结构破坏与慢性肝病进展为肝硬化和肝癌(HCC)相关,这既导致肝血管阻力增加和门静脉高压,又导致肝细胞灌注减少。另一方面,最近的证据表明,血管生成调节门体侧支循环的形成以及内脏血流增加,而这二者都参与了肝硬化危及生命的并发症。最后,血管生成在肿瘤生长中起关键作用,这表明干扰血管生成可能预防或延缓HCC的发展。本综述总结了目前关于肝脏血管生成分子机制以及血管生成在慢性肝病中的后果的知识。另一方面,它介绍了在实验模型中用于对抗过度血管生成的不同策略,以及其在预防向肝硬化转变、门静脉高压及其后果的发展中的潜在作用,及其在肝细胞癌治疗中的应用。
