Although the role of multiple humoral agents (such as plasma albumin, glucose, hormones etc.) are implicated in lipoprotein metabolism, the mechanism of action of these agents on various steps of the synthesis and secretion of lipoproteins and apolipoproteins (protein moieties of lipoproteins) are
The addition of sodium butyrate, a differentiation-inducing agent, to the culture medium of human hepatoblastoma-derived (Hep G2) cells, produced a dose-dependent and time-dependent increase in albumin (ALB) and decrease in T4-binding globulin (TBG) synthesis and secretion. In the presence of 0.01
Multicellular spheroids are useful as three-dimensional cell culture systems and for cell-based therapies. Their successful application requires an understanding of the consequences of spheroid size for cellular functions. In the present study, we prepared multicellular spheroids of different sizes
OBJECTIVE
In a recent study we described a population of small epithelial cells (SEC) in human hepatoblastoma that exhibit ultrastructural features of the oval cell of rodents. Both SEC and oval cells are immunoreactive for cytokeratin 7, a marker of biliary differentiation, and it was postulated
Hepatoblastomas (HBs) were induced in B6C3F1 male mice by diethylnitrosamine (DEN) and sodium phenobarbital (PB). Six-week-old mice received a single intraperitoneal dose of DEN followed by a continuous treatment with PB in diet at a concentration of 0 (group 1) or 500 (group 2) ppm for 50 weeks.
By cloning from cultivation in vitro of a human hepatoblastoma 3 epithelial cell lines were established, all of which produced alpha-fetoprotein and one of which did albumin in culture. Observation with electron microscopy demonstrated desmosomes and glycogen granules in the cytoplasm of these
We established a cell line (MHB-2) from a hepatoblastoma (HB) induced by diethylnitrosamine (DEN) and sodium phenobarbital (PB) in male B6C3F1 mice and examined the biological characteristics of MHB-2. MHB-2 cells grew as monolayers in culture and showed a spindle or polygonal shape.
BACKGROUND
Non-alcoholic fatty liver disease (NAFLD) is associated with obesity, insulin resistance and hepatic steatosis. Non-alcoholic steatohepatitis (NASH) is a serious consequence of NAFLD where chronic tissue damage and inflammation result in fibrosis which may progress to cirrhosis.
The MHB-2 cell line, established from a mouse hepatoblastoma (HB), was subjected to the reverse transcriptase-polymerase chain reaction (RT-PCR) for evaluation of gene expression related to cell differentiation. RNAs for c-kit, CD34, thy-1, albumin, cytokeratin (CK) 8, 18 and 19 could be detected,
To investigate whether atrial natriuretic factor regulates the growth of hepatocytes and to determine the receptor subtype involved in such modulation, we studied the effect of atrial natriuretic factor 103-126 and clearance receptor binding analogs of atrial natriuretic factor, (des-(Q116, S117,
To reveal growth factor and its signal pathway to CCAAT/enhancer binding protein alpha (C/EBPalpha) in hepatocyte differentiation, we used Huh-6 and HepG2, human hepatoblastoma (HBL) cell lines that maintain the expression of genes in hepatoblasts and remain at that stage of differentiation.
A human hepatoblastoma cell line, Hep G2, showed albumin production activity, a hepatic function, when cocultured with three-dimensional endothelialized tubes in collagen gels. The albumin production rate of the collagen-based liver-like constructs increased with increasing length of the
Albumin is a ubiquitous protein synthesized only by hepatocytes. Detection of albumin messenger RNA (mRNA) in neoplastic and non-neoplastic tissues using in situ hybridization may be useful in demonstrating hepatocellular differentiation. We investigated the presence of albumin mRNA by in situ
Spheroid cultures of human hepatoblastoma cells (HuH-6 line) were established by rotating 3 x 10(6) cells/3 ml culture medium in 25-ml Erlenmeyer flasks on a gyratory shaker. The size of the spheroids rapidly increased until 4 days of culture, and thereafter their size gradually increased until 8
BACKGROUND
Fatty acid ethyl esters (FAEEs) are nonoxidative metabolites of ethanol produced by the esterification of fatty acids and ethanol. FAEEs have been implicated as mediators of ethanol-induced organ damage in vivo and in vitro. They are detectable in the blood and in many organs after
