Abstract: Objective Liver fibrosis is caused by excessive deposition of extracellular matrix in liver tissues due to repeated liver injuries and hypoxia injury is a part of liver injury. Hypoxia inducible factor-1 α (HIF-1α) is a key transcription factor in response to hypoxia stress, and its expression in liver fibrotic tissues and activated HSCs is significantly increased. At present, a number of HIF-1α dependent genes and related signaling pathways have been studied to confirm that the changes of these genes and pathways are related to the development of liver fibrosis, suggesting that HIF-1α may play a key role in liver fibrosis. In this review, the mechanism of HIF-1α-related signaling pathway in the development of liver fibrosis and the synthesis and degradation of HIF-1α from the upstream are described.
