Journal Title: Journal of Clinical Hepatology - Year 2024, Vol 40, Issue 10
Abstract
[Objective] To investigate the effect of Kangxian Yiai Prescription （KXYA） on the mTOR/HIF-1α/VEGF signaling pathway in a rat model of precancerous lesions of liver cancer. [Methods] A total of 40 male Wistar rats were divided into normal group， model group， KXYA group， and Biejia Rangan Tablets （BJRG） group， with 10 rats in each group. The rats in the normal group were given intraperitoneal injection of normal saline at a dose of 0.4 mL/100 g， and those in the other three groups were given intraperitoneal injection of diethylnitrosamine at a dose of 50 mg/kg to establish a rat model of the precancerous lesions of liver cancer. Immunohistochemistry and Western Blot were used to measure the expression level of GST-Pi， and quantitative real-time PCR and Western Blot were used to measure the mRNA and protein expression levels of mTOR， HIF-1α， VEGF， PKM2， and GLUT1. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. [Results] Compared with the normal group， the model group had a significant increase in the protein expression level of GST-Pi in liver tissue （P<0.01）， and compared with the model group， the KXYA group had a significant reduction in the protein expression level of GST-Pi （P<0.05）. Compared with the normal group， the model group had significant increases in the mRNA expression levels of GLUT1 and PKM2 in liver tissue （P<0.01）， and compared with the model group， the BJRG group and the KXYA group had a significant reduction in the mRNA expression level of GLUT1 （P<0.05）. Compared with the normal group， the model group had significant increases in the protein expression levels of GLUT1 and PKM2 in liver tissue （P<0.01）. Compared with the normal group， the model group had significant increases in the mRNA expression levels of mTOR， HIF-1α， and VEGF in liver tissue （P<0.01）； compared with the model group， the BJRG group had significant reductions in the mRNA expression levels of mTOR and VEGF （P<0.05）， and the KXYA group also had significant reductions in the mRNA expression levels of mTOR and VEGF （P<0.01）. Compared with the normal group， the model group had significant increases in the protein expression levels of mTOR， HIF-1α， and VEGF in liver tissue （P<0.01）； compared with the model group， the BJRG group had a significant reduction in the protein expression level of mTOR （P<0.01）， and the KXYA group had significant reductions in the protein expression levels of mTOR， HIF-1α， and VEGF （P<0.05）； compared with the BJRG group， the KXYA group had a significantly higher protein expression level of mTOR （P<0.01）. [Conclusion] KXYA can inhibit the precancerous lesions of liver cancer by regulating the mTOR/HIF-1α/VEGF signaling pathway.
