Intervention Mechanism of Biejiajian Wan on Primary Liver Cancer by Regulating lncRNA SNHG5/miRNA-26a-5p/GSK-3β Signal Axis
To investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 (lncRNA SNHG5)/micro RNA-26a-5p (miRNA-26a-5p)/glycogen synthase kinase-3
β
(GSK-3
β
) signal axis.
Method
2
Double luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p, miRNA-26a-5p, and GSK-3
β
in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group, Biejiajian Wan low-dose group (0.5 g·kg
-1
), medium-dose group (1.0 g·kg
-1
), and high-dose group (2.0 g·kg
-1
), and sorafenib group (100 mg·kg
-1
), with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days, and the tumor volume was measured at different time. Hematoxylin-eosin (HE) staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5, miRNA-26a-5p, GSK-3
β
, and
β-
catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of GSK-3
β
and
β
-catenin in tumor tissue were detected by western blot.
Result
2
Compared with the SNHG5-WT (wild type) + miRNA NC (negative control) group, the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased (
P
<
0.05). Compared with the GSK-3
β
-WT + miRNA NC group, the relative luciferase activity of the GSK-3
β
-WT + miRNA-26a-5p mimic group was decreased (
P
<
0.05). Compared with the model group, the tumor volume of Biejiajian Wan low-dose, medium-dose, and high-dose groups was significantly decreased (
P
<
0.05,
P
<
0.01). Compared with the model group, the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis, which showed concentration-dependent changes. Compared with the model group, the expression levels of lncRNA SNHG5, GSK-3
β
, and
β
-catenin were decreased (
P
<
0.05,
P
<
0.01), while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan (
P
<
0.05,
P
<
0.01). Compared with the model group, the protein expression levels of GSK-3
β
and
β
-catenin were decreased in each dose group of Biejiajian Wan (
P
<
0.05,
P
<
0.01).
Conclusion
2
Biejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3
β
signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.
