Exploring the mechanism of action of Chinese medicine in regulating liver fibrosis based on the alteration of glucose metabolic pathways

In recent years, metabolic reprogramming in liver fibrosis has become a research hotspot in the field of liver fibrosis at home and abroad. Liver fibrosis is a pathological change caused by chronic liver injury from a variety of causes. Liver fibrosis is a common pathological feature of many chronic liver diseases such as chronic hepatitis B, non-alcoholic steatohepatitis, and autoimmune hepatitis, as well as the pathogenesis of the disease. The development of chronic liver disease into cirrhosis must go through the pathological process of liver fibrosis, in which hepatic stellate cells (HSC) play an important role. Following liver injury, HSC are activated and transdifferentiated into scar-forming myofibroblasts, which drive the trauma healing response and which rely on the deposition of collagen-rich extracellular matrix to maintain tissue integrity. This reaction will continue without strict control, which will lead to excessive accumulation of matrix and liver fibrosis. The mechanisms and clinical studies of liver fibrosis have been the focus of research in liver diseases. In recent years, several studies have revealed the mechanism of HSC metabolic reprogramming and the impact of this process on liver fibrosis, in which glucose metabolic reprogramming plays an important role in the activation of HSC, and it mainly meets the energy demand of HSC activation by upregulating glycolysis. Glycolysis is the process by which one molecule of glucose is broken down into two molecules of pyruvate and produces energy and lactate under anaerobic conditions. Various factors have been found to be involved in regulating the glycolytic process of HSC, including glucose transport, intracellular processing of glucose, exosome secretion, and lactate production, etc. Inhibition of the glycolytic process of HSC can be an effective strategy against liver fibrosis. Currently, the combined action of multiple targets and links of Chinese medicine such as turmeric, comfrey, rhubarb and scutellaria baicalensis against the mechanism of liver fibrosis can effectively improve or even reverse liver fibrosis. This paper summarizes that turmeric extract curcumin, comfrey extract comfreyin, rhubarb, Subtle yang yu yin granules, Scutellaria baicalensis extract oroxylin A and cardamom extract cardamomin affect liver fibrosis by regulating gluconeogenic reprogramming. Therefore, studying the mechanism of action of TCM in regulating liver fibrosis through reprogramming of glucose metabolism is promising to explore new methods and approaches for Chinese Medicine modernization research.
