Two echovirus 6 (EV6) strains were isolated from a clinical sample after successive sub-cultures in PLC (human hepatocellular carcinoma) and HeLa (human cervical adenocarcinoma) cells.
Our data showed that TSA selectively induced CYP2E1 in four studied human hepatocellular carcinoma (HCC) cell lines (Huh7, PLC/PRF/5, Hep3B and HepG2), but not in normal primary human hepatocytes.
Lenvatinib also exerted antitumor activity and potently reduced tumor microvessel density in PLC/PRF/5 xenograft model and two HCC patient-derived xenograft models.
We report here the isolation by molecular cloning and the analysis by heteroduplex and restriction enzyme mapping of seven distinct DNA fragments containing hepatitis B virus (HBV) sequences from genomic DNA of the PLC/PRF/5 human liver carcinoma cell line (the Alexander cell).
To study the mechanism of interleukin-6 (IL-6) induction of human C-reactive protein (CRP) gene expression, we have utilized a human hepatoma (PLC/PRF/5) cell culture system to analyze the trans-acting factors which bind to the 300 bp 5'-flanking region of human CRP gene.
To validate the ability of LECT2 to repress the growth of HCC, an adenoviral vector encoding the secreted human LECT2 (AdLECT2) was introduced into the human HCC cell lines Hep3B and PLC/PRF/5, which do not express endogenous LECT2.
The rearrangements of chromosome I are most striking in the Hep 3B and PLC/PRF/5 cell lines, which are derived from human hepatocellular carcinomas and contain integrated copies of the hepatitis B viral genome.
We analyzed liver tissue of patients with chronic hepatitis C (HepC) infection and hepatocellular carcinoma (HCC) as well as a human multi-tissue array, primary human hepatocytes and the hepatoma cell-lines HepG2, Hep3B and PLC by immunohistochemical staining and quantitative RT-PCR.
We found that sodium ascorbate blocked HCC-induced activation of sulfatase-2 leading to restoration of HSPGs receptors associated with reduction in IGF-2 and glypican-3.
In this study, we showed that GLIPR-2 was expressed in hepatocellular carcinoma (HCC) tissues, hypoxia could upregulate the expression of GLIPR-2 in HepG2 and PLC/PRF/5 cells in vitro, overexpression of this protein promoted migration and invasion via EMT, knockdown of GLIPR-2 attenuated migration and invasion of HepG2 and PLC/PRF/5 cells in hypoxia.
This study aimed at examining the effects of silibinin (a putative antimetastatic agent) on some transcriptional markers mechanistically related to HCC recurrence and metastasis in HepG-2 [hepatitis B virus (HBV)-negative and P53 intact) and PLC/PRF/5 (HBV-positive and P53 mutated) cells.
Chang liver cells are derived from normal liver tissue and express native p53, whereas hepatocellular carcinoma (HCC)-derived cell lines were Hep3B (p53-deleted) and PLC/PRF/5 (p53-mutant).
CRP mRNA accumulation in the hepatomaPLC/PRF/5 cell line was slightly more rapid, but of smaller magnitude in response to IL-1 beta (fourfold increase) than to IL-6 (10-fold increase); however, the amount of CRP protein accumulating in the culture medium was similar for both cytokines.
In this study, we have used a combination of transcriptomics and proteomics technologies to investigate the response of human hepatomaPLC/PRF/5 cells to prohibitin silencing to define in detail the biological function of hepatic Phb1 and to elucidate potential prohibitin-dependent mechanisms participating in the maintenance of the transformed phenotype.
Thereafter, IPA software was used to analyze potential effects of these genes, and the predicted results suggested that the Reg-mediated JAK/STAT, NF-κB, MAPK (ERK1/2, P38 and JNK), PLC, and PI3K/AKT signaling pathways may account for the activated inflammation and cell proliferation, and the attenuated apoptosis and cell death during the occurrence of AHF and HCC.
In addition to revealing genomic amplification and gene upregulation, we identified recurrent E135K (3/48 cases) mutations in HCC tissues and K237R mutation in the PLC/PRF/5 HCC cell line.
The present study aimed to analyze the effect of survivin on the tumorigenicity and chemosensitivity of HCC via the establishment of an HCC cell line (PLC/PRF/5) with the stable knockdown of the survivin gene (PLC‑k3).
The stimulatory effects of 4-hydroxytamoxifen on PLC/PRF/5 cell proliferation raise concerns regarding its use in the treatment of HCC in human patients and suggest that 4-hydroxytamoxifen may have no beneficial effects in some patients with HCC.
