ABSTRACT
This study aims to evaluate the anti-tumor and analgesic activities of Compound Kushen Injection(CKI) based on zebrafish model in vivo and investigate the anti-tumor mechanism. To be specific, zebrafish tumor xenotransplantation model was established by microinjection of murine LPC H12 cells into yolk sac. Then the high-dose CKI(H-CKI), medium-dose CKI(M-CKI), low-dose CKI(L-CKI) groups, and the model group were set. The anti-tumor activity of CKI was evaluated with the tumor area growth fold and integral absorbance(IA) growth fold 72 h after administration. The peripheral pain and central pain in zebrafish were respectively induced with acetic acid(AA) and phorbol myristate acetate(PMA). Zebralab ViewPoint system was employed to monitor behavioral trajectory of zebrafish, and movement times, movement time, movement distance, and movement velocity were used to evaluate the analgesic activity of CKI. Finally, real-time fluorescence quantitative polymerase chain reaction(RT-qPCR) was performed to detect the expression levels of apoptosis-related B lymphocyte tumor-2(Bcl-2) and phosphatidylinositol-3-kinase(PI3 K)/protein kinase B(Akt or PKB) pathway-related genes, for the verification of the anti-tumor mechanism. Compared with the model group, M-CKI and H-CKI significantly reduced the growth folds of tumor area and IA, relief the peripheral pain and central pain. The mechanism was that CKI can up-regulate the expression of cysteine aspartic acid specific protease-3(caspase-3, Casp3) and caspase-9(Casp9), down-regulate the expression of phosphoinositide 3-kinase(PI3 K) and Akt, and significantly reduce the expression of Bcl-2, hypoxia-inducible factor-1α(HIF-1α), and vascular endothelial growth factor(VEGF). In conclusion, CKI has significant inhibitory effect on tumor growth and pain, which is related to the PI3 K/Akt signaling pathway. The pathway mediates cell apoptosis, suppresses tumor growth, and alleviates tumor pain.
