Zhenzhu Xiaoji Decoction Induces Autophagy and Apoptosis Cell Death in Liver Cancer Cells through AKT/mTOR and JAK2/STAT3 Signaling Pathway.

Background: Liver cancer is one of the most common digestive tumors. The prescription Zhenzhu Xiaoji decoction (ZZXJD) has a certain effect on the growth and survival of primary liver cancer. Method: The research groups were divided into the model group, ZZXJD group, and cisplatin group. SMMC-7721 cells were treated with different concentrations of ZZXJD-medicated serum for 24 h and 48 h. The cell viability was measured with CCK8 assay, and cell morphology was observed by fluorescence microscope and transmission electron microscope (TEM). Western blot, RT-PCR, and gene chip were used to determine the protein expression level and gene expression level of cells and tumor tissues. Results: ZZXJD inhibited the proliferation activity of SMMC-7721 cells in a concentration- and time-dependent manner. The morphological changes of the cell showed apoptosis and autophagy. The gene expression of protein kinase B (AKT), mammalian target of rapamycin (mTOR), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3(STAT3) were downregulated compared with the model group( Conclusion: ZZXJD induced autophagy and apoptosis of liver cancer cells via inhibiting AKT/mTOR signaling pathway and JAK2/STAT3 signaling pathway, thereby affecting the growth and survival of liver cancer cells.
