Antiangiogenic Effects of Natural Compounds in Hepatic Inflammation

Abstract

Alcoholic Liver Disease (ALD) and Non-Alcoholic Fatty Liver Disease (NAFLD) are the most common causes of chronic liver disease and are increasingly emerging as a global health problem. Such disorders can lead to liver damage, resulting in the release of pro-inflammatory cytokines and the activation of infiltrating immune cells. These are some of the common features of ALD progression in ASH (alcoholic steatohepatitis) and NAFLD to NASH (non-alcoholic steatohepa-titis). Hepatic steatosis and subsequent fibrosis, whose continuous progression is accompanied by angiogenesis, lead to hypoxia, inducing the activation of vascular factors, which in turn triggers pathological angiogenesis and subsequent fibrosis, resulting in a vicious cycle. This condition further exacerbates liver injury and may contribute to the development of comorbidities, such as metabolic syndrome as well as hepatocellular carcinoma. Increasing evidence suggests that antiangiogenic therapy may have beneficial effects on these hepatic disorders and their exacerbation. Therefore, there is a great interest to deepen the knowledge of the molecular mechanisms of natural antiangiogenic products that could both prevent and control liver diseases. In this review, we focus on the role of major natural antian-giogenic compounds against steatohepatitis and determine their potential therapeutic benefits in the treatment of liver inflammation.

Research progress of traditional Chinese medicine in improving hepatic fibrosis based on inhibiting pathological angiogenesis

“…Pathological angiogenesis can lead to OS by creating a hypoxic environment, which in turn activates signaling pathways that promote ROS production (Coulon et al, 2011). OS then triggers the activation of HSCs and disrupts the balance between ECM synthesis and degradation, ultimately leading to the development of hepatic fibrosis (Coulon et al, 2011;Novi et al, 2023).…”
