The purpose of this study was to screen nimesulide for anticancer activity in chemically induced hepatocellular carcinoma in Wistar rats as well as in BEL 7402 and HEP G2 cell lines.
Here we showed that PP7 VLPs carrying a CPP penetrated hepatoma SK-HEP-1 cells and delivered the pre-microRNA-23b, which was processed into a mature product within 24 h; a concentration of 10 nM was sufficient for the inhibition of hepatoma cell migration via the downregulation of liver-intestine cadherin expression.
The cytotoxic activity of this analogue was screened on both Hep3B hepatocellular carcinoma and SK-Hep-1 liver adenocarcinoma cell lines by [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] (MTS) assay.
To assess ASCT2 and LAT1 as therapeutic targets, nine unique short hairpin RNA (shRNA) vectors were used to stably suppress transporter expression in human epithelial (Hep3B) and mesenchymal (SK-Hep1) hepatocellular carcinoma (HCC) cell lines.
Treatment with lipopolysaccharide (LPS), a TLR4 agonist, was found to significantly upregulate TLR4 expression in HepG2 cells, but not in malignant Huh-7 and Sk-Hep1hepatocellular carcinoma cells.
In this study, we analyzed the methylation status of the promoter region of RASSF1A using bisulfite sequencing and PCR-RFLP in four liver cancer cell lines (Hep3B, HepG(2), SK-HEP-1, and Huh-7) and a cohort of 43 hepatitis B virus-associated hepatocellular carcinoma (HCC) tissues and their corresponding nontumor tissue specimens.
It is observed that SAHA analogs significantly inhibited cell proliferation and induced apoptosis in hepatocellular carcinoma (HCC) cell lines HepG2 and SK-HEP-1.
Hepatoma cell lines (BEL-7402 and SK-Hep1) were treated with HBO at 2 atmosphere absolute pressure for 80 min per day or combined with sorafenib or cisplatin.
Morphologic, cytochemical, and immunocytochemical examinations demonstrated that both poorly differentiated CSF-producing HCC cell lines (HA22T/VGH and SK-Hep-1) were macrophage-like in morphology, possessed nonspecific esterase (NSE) activity, and expressed CD14, CD68, and HLA-DR on their surface, while all the well-differentiated HCC cell lines were epithelioid and lacked myeloid differentiation antigens.
We stably transfected HDGF shRNA into SK-HEP-1 human HCC cells and investigated the effects of HDGF reduction on HCC growth using a cell proliferation assay and a murine xenograft model.
The re-introduction of LZAP expression in the HepG2 and sk-Hep1HCC cell lines significantly inhibited proliferation and colony formation in the HCC cells and induced G1 phase arrest and apoptosis of the HCC cells in vitro.
Among 7 hepatoma cell lines analyzed, 5-alpha-fetoprotein (AFP)-producing hepatoma cell lines (HepG2, Huh7, Hep3B, PLC/PRF/5, and Huh6) were shown to have common gene-expression profiles compared with those of AFP-negative hepatoma cell lines (HLE and SK-Hep1) and cancer cell lines of nonhepatocyte origin (HeLa and KMBC).
The aim of the present study is to investigate the effect of regorafenib on NF-κB-modulated tumor progression in HCC bearing mouse model. pGL4.50 luciferase reporter vector transfected SK-Hep1 (SK-Hep1/<i>luc2</i>) and Hep3B 2.1-7 tumor bearing mice were established and used for the present study.
Using RT-QPCR and Taqman low density arrays we have analyzed biopsies from healthy livers or surgically removed tumors from naive patients and cell lines derived from HCC (SK-HEP-1, Alexander and Huh7), CGC (TFK1) and HPB (HepG2), before and after exposure to cisplatin at IC50 for 72 h. In liver tumors FXR expression was not enhanced but significantly decreased (healthy liver > HCC > HPB ≈ CGC).
In this report, an immunoprecipitate activity assay of protein kinase FA/glycogen synthase kinase-3 alpha (kinase F(A)/GSK-3 alpha) (a member of PDPK family) has been optimized for human hepatoma and used to demonstrate for the first time significantly increased (P < 0.01) activity in poorly differentiated SK-Hep-1hepatoma (24.2 +/- 2.8 units/mg) and moderately differentiated Mahlavu hepatoma (14.5 +/- 2.2 units/mg) when compared to well differentiated Hep 3B hepatoma (8.0 +/- 2.4 units/mg).
We used human HCC cell lines (BEL-7402, SMMC-7721, Hep-G2, Hep-3B, SK-hep1 and Huh7) and a normal hepatocyte cell line (LO2) along with HCC samples from patients who had undergone resection for HCC previously at our hospital.
HCC cell lines SMMC-7721 and SK-HEP1 stably knockdown and knockout of TAZ were established by the lentiviral-mediated TAZ knockdown and knockout approaches.
By performing in vitro experiments, we observed TKT was significantly increased, but OLFM2 was decreased in high metastatic potential HCC cell lines (SK-HEP-1 and MHCC-97 H) compared with low metastatic potential cell line Huh7 and normal human liver cell line LO2 using western blotting analysis.
We established a xenograft model of liver metastasis by injecting the spleen of SCID mice with MKN-45 human gastric cancer cells and also a primary liver cancer model by injecting SK-HEP-1 human hepatocellular carcinoma cells into the liver.
We investigated the causes of this low CYP activity by analysing the activity, protein, mRNA and heterologous nuclear RNA contents of the most important CYPs involved in drug metabolism (1A1, 1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, 3A4, 3A5) in cultured human hepatocytes, and in HepG2 and Mz-Hep-1hepatoma cell lines.2.
