Abstract
Abnormal expression levels of microRNA-204 (miR-204) have been identified in various types of human cancer. However, the expression and functions of miR-204, and the underlying molecular mechanism involved in the initiation and progression of hepatocellular carcinoma (HCC), require further investigation. The results of the present study demonstrated that miR-204 is downregulated in HCC tissues and cell lines. Notably, zinc finger E-box binding homeobox 2 (ZEB2) was identified as a direct target of miR-204 in HCC. In addition, miR-204 negatively regulates ZEB2 expression level in HCC cells at the post-transcriptional level. In functional studies, the overexpression of miR-204 inhibited the proliferation, migration and invasion of HCC cells. Furthermore, the knockdown of ZEB2 may mimic the functions of miR-204 in HCC cells, suggesting that ZEB2 is a direct functional target of miR-204. In conclusion, the results of the present study indicated that miR-204 suppresses the tumor growth, migration and invasion of HCC cells by directly targeting ZEB2, and may serve as a novel therapeutic target for HCC.

Abstract
Unlike systemic chemotherapy for hematological malignancies with hepatitis B virus (HBV) infection, transarterial chemoembolization (TACE) for HBV-related hepatocellular carcinoma (HCC) has only recently been reported to cause HBV reactivation and subsequent hepatitis. Most patients with HBV-related HCC have an underlying disease with liver fibrosis or cirrhosis, and TACE may potentially induce HBV reactivation and liver decompensation. Currently, there are no clinical guidelines for managing TACE-caused HBV reactivation. In this review, we summarize the changes of HBV status and liver function after TACE and the effect of antiviral treatment before, during, or after TACE.

Abstract
Many chemotherapeutic agents have been successfully used to treat hepatocellular carcinoma (HCC); however, the development of chemoresistance in liver cancer cells usually results in a relapse and worsening of prognosis. It has been demonstrated that DNA methylation and histone modification play crucial roles in chemotherapy resistance. Currently, extensive research has shown that there is another potential mechanism of gene expression control, which is mediated through the function of short noncoding RNAs, especially for microRNAs (miRNAs), but little is known about their roles in cancer cell drug resistance. In present study, by taking advantage of miRNA effects on the resistance of human hepatocellular carcinoma cells line to cisplatin, it has been demonstrated that miR-340 were significantly downregulated whereas Nrf2 was upregulated in HepG2/ CDDP (cisplatin) cells, compared with parental HepG2 cells. Bioinformatics analysis and luciferase assays of Nrf2-3'-untranslated region-based reporter constructor indicated that Nrf2 was the direct target gene of miR- 340, miR-340 mimics suppressing Nrf2-dependent antioxidant pathway and enhancing the sensitivity of HepG2/ CDDP cells to cisplatin. Interestingly, transfection with miR-340 mimics combined with miR-340 inhibitors reactivated the Nrf2 related pathway and restored the resistance of HepG2/CDDP cells to CDDP. Collectively, the results first suggested that lower expression of miR-340 is involved in the development of CDDP resistance in hepatocellular carcinoma cell line, at least partly due to regulating Nrf2-dependent antioxidant pathway.

Potential risk factors for the reactivation of the replication of hepatitis B and C viruses after transcatheter arterial chemoembolization of hepatocellular carcinoma. Kaohsiung J Med Sci 2011; 27:554-9. [PMID: 22208538 DOI: 10.1016/j.kjms.2011.06.029] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2011] [Accepted: 05/16/2011] [Indexed: 01/02/2023] Open
Abstract
The purpose of this study was to investigate the potential risk factors for the reactivation of the replication of hepatitis B virus (HBV) and hepatitis C virus (HCV) after transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma. Forty-four hepatocellular carcinoma patients treated by TACE using epirubicin plus mitomycin C were studied. Serum HBV DNA (n=17) and HCV RNA (n=27) levels were measured 1 day before and 3 months after TACE. Plasma concentrations of chemotherapeutic agents were determined at 1 hour and 72 hours after TACE. A total of 29 patients (n=13 for chronic hepatitis Band n=16 for chronic hepatitis C) showed significant changes of the viral loads after TACE. Patients with increased viral loads after TACE were older (p=0.041), had higher incidence of pre-TACE white blood cell counts being less than normal limit (p=0.023), and had higher plasma mitomycin C concentrations (p=0.039) than those in patients with decreased viral loads. Analysis by multiple logistic regressions using age, decreased or normal pre-TACE white blood cell counts, mitomycin C concentrations >3.95 ng/mL adopted by receiver operating characteristic curve (p=0.037), and epirubicin concentrations have shown that decreased pre-TACE white blood cell counts was the only significant factor associated with increased viral loads after TACE (p=0.048). In conclusion, patients with decreased pre-TACE white blood cell counts have a potential risk for the reactivation of the replication of HBV or HCV after TACE.
