ABSTRACT
Erianin is a natural small molecule dibenzyl compound extracted from Dendrobium officinale or Dendrobium chrysotoxum. Studies show erianin has many pharmacological functions such as antioxidant, antibacterial, antiviral, improving diabetic nephropathy, relaxing bronchial smooth muscle and anti-tumor. However, the erianin-mediated molecular mechanism is elusive, and the target protein of erianin is not clear yet. Here, we screened and identified that the target protein of erianin in human hepatoma HepG2 cells is human pyruvate carboxylase, and explored the anti-tumor signal pathway regulated by erianin in several cell lines. Firstly, the interaction between human pyruvate carboxylase and erianin was studied by bioinformatics and biochemical methods. Secondly, in vitro, erianin can specifically inhibit the activity of human pyruvate carboxylase, and the purified human pyruvate carboxylase can specifically bind to the activity probe of erianin. Thirdly, human pyruvate carboxylase is highly expressed in a variety of malignant tumors, and the inhibitory effect of erianin on tumor cells is positively correlated with the expression of human pyruvate carboxylase, and erianin can selectively inhibit the activity of pyruvate carboxylase. Finally, erianin can regulate the pyruvate carboxylase-mediated Wnt/ ß- Catenin pathway. All of which provide important data for the further study of the anticancer mechanism of erianin, and lay a solid foundation for the further development and utilization of erianin.
