Effect of Lenvatinib treatment on the cell cycle and microRNA profile in hepatocellular carcinoma cells.

ABSTRACT: Lenvatinib is a tyrosine kinase receptor inhibitor used to treat unresectable hepatocellular carcinoma (HCC). In this study, we investigated the antitumor effects of Lenvatinib treatment on HCC cell lines. Proliferation was examined in four HCC cell lines (HuH-7, Hep3B, Li-7, and PLC/PRF/5) using Cell Counting Kit-8 assays. Xenograft mouse models were used to assess the effects of Lenvatinib in vivo. Cell cycle, western blotting, and microRNA (miRNA) expression analyses were performed to identify the antitumor inhibitory potential of Lenvatinib on HCC cells. Lenvatinib treatment suppressed proliferation of HuH-7 and Hep3B, but not Li-7 and PLC/PRF/5 cells and induced G₀/G₁ cell cycle arrest and cyclin D1 downregulation in Lenvatinib-sensitive cells. Lenvatinib treatment also reduced tumor growth in HuH-7 xenograft mouse models. miRNA microarrays revealed that Lenvatinib treatment altered the expression of miRNAs in HuH7 cells and exosomes. Our results demonstrated the therapeutic potential of Lenvatinib and provide molecular mechanistic insights into its antitumor effects for treating HCC.

Project description:BackgroundMicroRNAs (miRNAs) exhibit essential regulatory functions related to cell growth, apoptosis, development and differentiation. Dysregulated expression of miRNAs is associated with a wide variety of human diseases. As such miRNA signatures are valuable as biomarkers for disease and for making treatment decisions. Hepatitis B virus (HBV) is a major risk factor for hepatocellular carcinoma (HCC). Here we screened for miRNAs in chronic HBV associated HCC.MethodsTo determine the miRNAs in HCC occurrence associated with HBV infection, we analyzed global miRNA expression profiles in 12 pairs of HCC and adjacent matched non-HCC tissues from HBV-positive and HBV-negative patients using microarray analyses. The microarray result was validated by real-time PCR in 32 HBV-positive and 24 HBV-negative patient HCC samples. The potential candidate target genes of the miRNAs were predicted by miRWalk software. Genes simultaneously predicted as targets by two or more miRNAs were subjected to GO and KEGG pathway analysis. The miRNA regulatory network analysis was performed using the Ingenuity Pathway Analysis (IPA) software.ResultsEight miRNAs (miR-223, miR-98, miR-15b, miR-199a-5p, miR-19b, miR-22, miR-451, and miR-101) were involved in HBV-unrelated HCC, 5 miRNAs (miR-98, miR-375, miR-335, miR-199a-5p, and miR-22) were involved in HBV infection, and 7 miRNAs (miR-150, miR-342-3p, miR-663, miR-20b, miR-92a-3p, miR-376c-3p and miR-92b) were specifically altered in HBV-related HCC. Gene Ontology and KEGG analyses predict that these HBV-related HCC miRNAs are involved in the regulation of: transcription, RNA polymerase II promoter, phosphorylation of proteins through MAPK signaling pathway, focal adhesion, and actin cytoskeleton. IPA analysis also suggest that these miRNAs act on AGO2, TP53, CCND1, and 11 other genes that significantly influence HCC occurrence and HBV infection.ConclusionOur data indicates that the unique 7 miRNAs expression signature could be involved in the development HBV- related HCC.
