This study was designed to investigate the mechanism by which miR-129-5p affects the biological function of liver cancer cells. The expression levels of miR-129-5p in liver cancer tissues and cells were, respectively, determined. Crystal violet staining and flow cytometry were used to detect cell proliferation and apoptosis. Wound healing assay and transwell assay were performed to test cell migration and invasion. The target gene of miR-129-5p was analyzed and verified by bioinformatics analysis and luciferase reporter assay. Tumorigenicity assays in nude mice were used to test the antitumor ability of calcium calmodulin-dependent protein kinase IV (CAMK4). miR-129-5p was found to be underexpressed in hepatocellular cancer tissues and cells and also to inhibit liver cells proliferation, migration, and invasion and promote apoptosis. CAMK4 was a direct target for miR-129-5p and was lowly expressed in liver cancer tissues and cells. CAMK4 was also found to inhibit liver cells proliferation, migration and invasion, and promote apoptosis. CAMK4 might exert an antitumor effect by inhibiting the activation of mitogen-activated protein kinase (MAPK). MiR-129-5p was a tumor suppressor with low expression in liver cancer tissues and cells. CAMK4, which is a direct target gene of miR-129-5p, could inhibit tumor by inhibiting the activation of MAPK signaling pathway.

Oncolytic virus therapy is emerging as important means in cancer treatment. In a previous study, we constructed a dual cancer-specific antitumor recombinant adenovirus, designating it Ad-apoptin-hTERTp-E1a (Ad-VT). This study aimed to investigate the anticancer potential of recombinant adenovirus Ad-apoptin-hTERTp-E1a (Ad-VT) in liver cancer. Crystal Violet staining and CCK-8 assays were used to analyse the inhibitory effect of recombinant adenovirus on human hepatoma cell line QGY-7703 and SMMC-7721. Ad-VT had a significant tumour killing inhibitory effect on QGY-7703 and SMMC-7721 cells that was both dose and a time dependent. Ad-VT-induced apoptosis of QGY-7703 cells was detected using Hoechst, Annexin V, and JC-1 staining, as well as western blotting. Recombinant adenovirus had a strong apoptosis-inducing effect on QGY-7703 cells, and killed QGY-7703 cells mainly through the mitochondrial apoptotic pathway. QGY-7703 cells invasion were detected using cell-scratch and Transwell assays. Recombinant adenovirus could significantly inhibit the invasion of QGY-7703 cells over a short period of time. The pGL4.51 plasmid was used to transfect QGY-7703 cells to construct tumour cells stably expressing luciferase (QGY-7703-LUC). The tumour inhibition effect of Ad-VT in vivo was subsequently confirmed by establishing a tumour-bearing nude mouse model. Ad-VT could effectively inhibit tumour growth and prolong survival of the mice. Recombinant adenovirus Ad-VT has the characteristics of tumour-specific replication and specific tumour killing, and could inhibit the growth of liver cancer QGY-7703 cells and promote their apoptosis.

Combination therapy has been the trendy of care, particularly in cancer remedy, since it is a rational approach to increase response and tolerability and to diminish resistance. Hence, there is a growing interest in combining anticancer drugs to maximizing efficacy with minimum systemic toxicity through the delivery of lower drug doses. Therefore, in the present study, the value of combination between benzethonium chloride (benzo) and endoxan (endo) as anti-tumor drug sensitization of hepatocellular carcinoma HCC treatment were detected both in vitro and in vivo. Crystal violet test was performed to detect the proliferation of HepG2 cells treated with benzo or/and endo. In addition, the HCC rat model was established by diethylnitrosamine (DEN) administration. The antitumor effect was enhanced with the combined treatment of the two drugs, particularly in the group with benzo and endo. The results confirmed that the HCC condition was developed in response to lower expressions of caspase 3 and P53 which, in turn, was due to the overexpression of Bcl-2, and downregulation of cytochrome C. The treatment with benzo combined with endo caused significant activation of caspase-3 mediated apoptotic signals that could be responsible for its anti-HCC potential. Meantime, benzo combined with endo treatments could reduce the hepatocellular carcinogenesis by reducing the expression of MMP-9. Therefore, benzo and endo treatments may be a hopeful therapeutic drug for HCC. Also, more studies are recommended to feat the idea of this research for medical use.<br />.
