Although various in vitro assays have been developed to evaluate the cytochrome P450 (CYP)-inducing potential of drug candidates, there is a continuing need for the development of a reliable model in drug discovery. The objective of the present study was to compare CYP induction by chemicals in HepG2 cells with Huh7, NKNT-3, and reverted NKNT-3 cells. HepG2 cells showed more similarity to human...

A multivalent galactosyl carborane derivative 10 (dendritic glyco-borane, DGB) was synthesized and demonstrated as a potential cell-targeting agent in BNCT with HepG2 cells. DGB 10 improved the delivery of boron to HepG2 cells and neutron irradiation data show DGB 10 with ten-fold improvement at killing the HepG2 cells over BSH.

The successful encapsulation of human hepatocellular carcinoma (HepG2) cells would assist applications in tissue engineering. In this paper, we have developed a method to produce chitosan-alginate microfibers within a microfluidic chip. Also, by suspending cells in the mixing solution, we fabricated HepG2 cell-laden fibers. The encapsulated HepG2 cells in the chitosan–alginate fibers were more ...

In this paper, we demonstrate formation of size-controlled 3-dimensional hetero-spheroids using a micro-fluidic device in approximately 2 min. The device collects cells in the center of a micro-chamber using micro-rotational flow as shown in Fig. 1. In previous work, we used this device to generate size-controlled HepG2 spheroids [1]. We applied it to form heterospheroids consisting of HepG2 an...

Hepatoma cells derived from liver carcinoma are a candidate cell source for bioartificial (BAL) systems due to their high proliferative capacity, although function of hepatoma is considerably low compared with primary hepatocytes. In our previous study, genetically engineered mouse inducible were established by transducing liver-enriched transcription factor (LETF) genes. this we aimed develop ...

Accumulating evidence indicates that Nanog plays a central role in modulating the biological behaviors of human hepatocellular carcinoma (HCC). However, the underlying mechanisms remain unclear. In the present study, we employed transcription activator-like effector nucleases (TALEN) to disrupt Nanog expression in HepG2 cells and obtained subcloned cells with diallelic Nanog mutations. Signific...

The primary reservoir for hepatitis C virus (HCV) replication is believed to be hepatocytes, which are highly polarized with tight junctions (TJ) separating their basolateral and apical domains. HepG2 cells develop polarity over time, resulting in the formation and remodeling of bile canalicular (BC) structures. HepG2 cells expressing CD81 provide a model system to study the effects of hepatic ...

Primary human hepatocytes (PHH) are a main instrument in drug metabolism research and in the prediction of drug-induced phase I/II enzyme induction in humans. The HepG2 liver-derived cell line is commonly used as a surrogate for human hepatocytes, but its use in absorption, distribution, metabolism, and excretion and toxicity studies can be limited because of lowered basal levels of metabolizin...
