BACKGROUND: Liver transplantation is a well-established treatment for HCC in carefully selected patients. Risk factors for tumors with poor prognostic features on explant have not been well described in a national cohort. METHODS: We performed a retrospective cohort study of adult LT recipients with HCC transplanted from 4/8/12 (when explant pathology in UNOS became available) until 9/30/2014. We evaluated the association between listing diagnosis and other demographic factors with tumor features on explant using logistic regression...

Paired-box family member PAX8 encodes a transcription factor that has a role in cell differentiation and cell growth and may participate in the prognosis of hepatocellular carcinoma (HCC). By bioinformatics analysis, we identified several single nucleotide polymorphisms (SNPs) within a newly identified long non-coding RNA (lncRNA) AC016683.6 as expression quantitative trait loci (eQTLs) for PAX8. Hence, we hypothesized that PAX8eQTLs in lncRNA AC016683.6 may influence the HCC prognosis. We then performed a case-only study to assess the association between the two SNPs as well as the prognosis of HCC in 331 HBV-positive HCC patients without surgical treatment...

Hepatocellular carcinoma (HCC) is one of the most common and lethal malignancies in the world. Sox2 is a potential oncogene in the pathogenesis of HCC, however, the actual mechanisms of Sox2 functions in HCC has not emerged yet. In this study, we explored the expression, function and the relationship between Sox2 and PD-L1 in HCC. We found that both Sox2 and PD-L1 were expressed at a markedly higher level in HCC tissues in comparison to adjacent non-tumor tissues. Moreover, the expression levels of both genes were correlated with each other...

Hepatitis B virus (HBV) is mainly suspected to promote hepatocellular carcinoma (HCC) development by epigenetic alteration. The HBV X protein (HBx) plays a key role in the molecular pathogenesis of HBV-related HCC. However, the mechanism of HBx-mediated hepatocarcinogenesis remains to be elucidated. RIZ1 gene, a candidate HCC suppressor gene, is frequently found to be hypermethylated and downregulated in HCC. In the present study, we show that the expression of RIZ1 was downregulated in 65% HCC tissues. Decreased expression of RIZ1 was restored by 5'-Aza in MHCC-97H HCC cell lines...

The mechanism of early recurrence of hepato-cellular carcinoma (HCC) is not well understood. To examine whether early intrahepatic metastasis of HCC can be determined by the reliable molecular characteristics of the primary HCC, we focused on early-stage tumors of primary and solitary HCC cases. Proteomic differences were investigated between two groups, 11 early (recurrence within 12 months) and 10 late (no recurrence within 48 months) HCC cases, using two-dimensional fluorescence difference gel electrophoresis...

Breast cancer metastasis suppressor 1 (BRMS1) can specifically regulate tumor metastasis in many cancers. Our previous studies have demonstrated that BRMS1 can promote cell apoptosis through regulating osteopontin (OPN) expression in hepatocellular carcinoma (HCC) cells. However, the transcriptional targets of BRMS1 have not been thoroughly studied. In this study, death-associated protein kinase 1 (DAPK1), a tumor suppressor gene with multiple roles in regulating cell death, was identified as a potential transcriptional target of BRMS1 in the whole genome expression microarray...

Aberrant expression of Abelson interactor 1 (ABI1) has been reported in multiple cancers. However, its clinical significance and potential biological roles in hepatocellular carcinoma (HCC) have not been fully elucidated. In this study, we found that ABI1 was obviously upregulated in HCC tissues compared with non-tumor tissues. Moreover, high ABI1 expression was significantly correlated with tumor size (P=0.041), tumor number (P<0.001), tumor encapsulation (P<0.001) and BCLC stage (P=0.010). Importantly, Kaplan-Meier survival analysis showed that increased ABI1 expression predicted shorter overall survival time (P<0...

Although vitamin K2 (VK2) exhibits inhibitory effects on the viability of hepatoma cells, hepatoma cells are insensitive to VK2. Therefore, this investigation is an attempt to enhance the sensitivity of hepatoma cells to VK2. Our results showed that VK2 acted synergistically with ethanol (EtOH) to inhibit the viability of Smmc-7721 cells, mainly because cytochrome P450 2E1 (CYP2E1) was activated by EtOH. The synergistic effect of VK2 and EtOH was also observed in QGY-7703 cells, which also express CYP2E1. However, in HepG2 cells, which do not express CYP2E1, the synergistic effect of VK2 and EtOH was not observed...

Hepatocellular carcinoma (HCC) is the most common type of liver cancer in humans. The focal adhesion tyrosine kinase (FAK) is often over-expressed in human HCC and FAK inhibition may reduce HCC cell invasiveness. However, the anti-oncogenic effect of FAK knockdown in HCC cells remains to be clarified. We found that FAK depletion in HCC cells reduced in vitro and in vivo tumorigenicity, by inducing G2/M arrest and apoptosis, decreasing anchorage-independent growth, and modulating the expression of several cancer-related genes...

A series of novel indazole-based diarylurea derivatives targeting c-kit were designed by structure-based drug design. The derivatives were prepared and their antiproliferative activities were evaluated against human colon cancer HCT-116 cell line and hepatocellular carcinoma PLC/PRF/5 cell line. The antiproliferative activities demonstrated that six out of nine compounds exhibited comparable activities with Sorafenib against HCT-116. The structure-activity relationship (SAR) analysis indicated that the indazole ring part tolerated different kinds of substituents, the N position of the central pyridine ring played key roles in antiproliferative activity...

Three new complexes bearing the tridentate hydrazone-based ligand 2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)pyridine (L) were synthesized and structurally characterized. Biological tests indicate that the Zn(ii) complex [ZnCl2(L)] is of low cytotoxicity against the hepatocellular carcinoma cell line HepG2. In contrast, the Cu(ii) and Mn(ii) complexes [CuCl2(L)] and [MnCl2(L)] are highly cytotoxic with EC50 values of 1.25 ± 0.01 μM and 20 ± 1 μM, respectively. A quantitative proteome analysis reveals that treatment of the cells with the Cu(ii) complex leads to a significantly altered abundance of 102 apoptosis-related proteins, whereas 38 proteins were up- or down-regulated by the Mn(ii) complex...

MicroRNA (miRNA) expression has been linked to the molecular pathogenesis of hepatocellular carcinoma (HCC). The aberrant expression of miRNA is involved in the processes of tumorigenesis and cancer progression. According to the latest research, miR-888-5p is associated with strong cancer-promoting effect. For instance, miR-888-5p is up-regulated in prostate cancer and breast cancer. Nevertheless, the role of miR-888-5p in HCC has not been investigated to date. In this study, we found that miR-888-5p levels in four HCC cell lines (SMMC7721, HepG2, Huh-7 and Bel7402) were significantly up-regulated compared with human hepatocyte cell line (HHL-5)...
