Rapidly proliferating normal and malignant cells had a greater initial rate of amino acid incorporation into microsomal proteins than did normal cells. The rate of micro.somal protein renewal in Novikoff hepatoma was greater than that of liver cells. The initial rates of amino acid incorporation into hepatoma and liver ribonucleoprotein particles were approximately equal. The soluble fractions ...

Liver cancer is the fifth most common cause of cancer death worldwide. The study of more effective anti-hepatoma drugs is urgently required. Bufalin has been isolated from a traditional Chinese medicine and possesses less toxicity to normal cells. However, it has been found to inhibit growth of cancer cells. In this study, we aimed to investigate the efficacy and mechanism of bufalin in Huh7, H...

The contents of nucleic acids in rat liver and hepatoma mitochondria and the physico-chemical properties on DNA’s isolated from these mitochondria were comparatively investigated. The results are briefly summarized as follows. 1. The contents of DNA and RNA per mg protein of the hepatoma cell mitochondria were about 10 and 2 to 4 times higher than those of rat liver mitochondria, respectively. ...

Force feeding of large amounts of triparanol to rats bearing transplanted hepatomas results in appearance of myeloid bodies in liver cells and in hepatoma cells. The myeloid bodies are most numerous in liver cells, less abundant in the cells of Morris 5123 hepatoma, and rare in the cells of Novikoff hepatoma. The quantity of myeloid bodies can be correlated with development of endoplasmic retic...

The hepatic bile acid transporter NTCP is a high-affinity receptor for hepatitis B and D viruses. This study shows that TLC rapidly accumulates in NTCP-expressing hepatoma cells mediates long-lasting trans-inhibition of NTCP’s function via an intracellularly accessible domain, without substantially affecting its membrane expression. domain promising novel target site pharmacological long-acting...

Hepatocellular carcinoma is one of the most common cancers in the world. Previously, we found that the level of glucocorticoid receptor was significantly higher in hepatocellular carcinoma than in adjacent liver tissues. Moreover, in vitro and in vivo studies showed that glucocorticoid stimulated the growth of hepatoma cells. On the other hand, endogenous metabolites such as 2-methoxyestradiol,...

BACKGROUND This study investigates the effects of human bone marrow-derived mesenchymal stem cell (hMSC) on migration and proliferation ability of hepatocellular carcinoma (HCC) with high- and low-metastatic potential. METHODS The hMSC and transforming growth factor-β1 (TGFβ-1) gene infected hMSC were co-cultured with hepatoma cells. The ability of cells migration was assessed by Transwell as...

A rat hepatoma cell line was shown to synthesize heparan sulfate and chondroitin sulfate proteoglycans. Unlike cultured hepatocytes, the hepatoma cells did not deposit these proteoglycans into an extracellular matrix, and most of the newly synthesized heparan sulfate proteoglycans were secreted into the culture medium. Heparan sulfate proteoglycans were also found associated with the cell surfa...

We previously reported that the retroviral vector expressing the herpes simplex virus-thymidine kinase gene under the control of 0.3-kb human a-fetoprotein (AFP) gene promoter (AF0.3) provided the cytotoxicity to ganciclovir (GCV) in high-AFP-producing human hepatoma cells but not in low-AFP-producing cells. Therefore, specific enhancement of AFP promoter activity is likely to be required to in...
