The Comprehensive Effects ofCarassius auratusComplex Formula against Lipid Accumulation, Hepatocarcinogenesis, and COVID‐19 Pathogenesis via Stabilized G‐Quadruplex and Reduced Cell Senescence

Abstract

Carassius auratus complex formula (CACF) is a traditional Chinese medicine known for its antidiabetic effects. Hepatocellular carcinoma (HCC) is a major cause of cancer‐related deaths worldwide, and there are currently no effective therapies for advanced HCC. This study explores the comprehensive effects and possible mechanisms of CACF on HCC. The results show that CACF reduces the viability of hepatoma cells in vitro, while benefiting normal hepatocytes. In addition, CACF inhibits hepatoma cell growth in a zebrafish xenotransplantation model and decreases lipid accumulation, represses inflammation and cell proliferation markers in fatty acid translocase (CD36) transgenic zebrafish, and inhibits the expression of cell proliferation and β‐catenin downstream targets in telomerase (tert) transgenic zebrafish models. Ingenuity Pathway Analysis reveals that CACF exerts multiple functions, including reduction of inflammation and inhibition of lipid transporter and PPAR signaling pathway. Surprisingly, CACF also regulates the expression of genes and reduces coronavirus infection and pathogenesis in a zebrafish model. CACF treatment is validated to regulate the expression of genes for anti‐coronavirus activity. Mechanistically, CACF stabilizes G‐quadruplex and reduces cell senescence associated β‐galactosidase activity. In summary, CACF may be a promising therapeutic agent with multiple functions including anticancer, anti‐inflammation, and anti‐microorganisms in a zebrafish model.
