Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Pazopanib is a drug with idiosyncratic hepatotoxicity risk. Analysis of gene expression changes after exposing hepatocytes can indicate effects on specific biological pathways and potential mechanisms of hepatotoxicity. HLCs derived from patient-specific iPSCs were treated with pazopanib to identify both drug-related global effects and patient-specific effects

Description
Several biological pathways can be under the regulation of miRNAs. These pathways can be indentified by the enforced expression of a miRNA and analysing the expression data for enrichment of specific pathways represented among the genes differentially expressed upon miRNA overexpression.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Enforced expression of miRNAs in cells leads to down-regulation of several mRNAs which harbour binding sites in their 3'UTRs for the overexpressed miRNA and represent potential target genes of the miRNA

Description
There is an evident, unmet need to develop a commercially available in vitro system that can model inflammatory states of the liver and predict immune-mediated hepatotoxicity of drugs and xenobiotics taken under inflamed conditions. Hepatocyte-Kupffer cell co-cultures can model inflammation-mediated hepatotoxicity; however, Kupffer cell (KC) source remains an important bottleneck for the development of such models. Primary human Kupffer cells (PHKCs) are costly, limited in availability and exhibit donor variability. An alternative cell source for KCs has not been reported. Important paradigm shift from the classical dogma of adult blood-circulating monocyte-derived macrophages to intrahepatic precursor/fetal monocyte-derived macrophages has shed new light into the origin of KCs in vivo. Based on these recent findings, we report here, a novel method to generate human KCs in vitro from stem cells (hPSC-KCs) via fetal monocytes. hPSC-KCs expressed macrophage markers, CD11, CD14, CD68, CD163 and CD32 at gene and protein level and exhibited functional properties such as phagocytosis and Interleukin-6 and Tumor Necrosis Factor-4alpha production upon activation. Importantly, molecular signature, liver-macrophage specific CLEC-4F expression and cytokines production levels of hPSC-KCs were similar to PHKCs but different from non-liver macrophages. We used an inflammatory liver co-culture model to demonstrate that activated hPSC-KCs, but not non-liver macrophages, were able to recapitulate effects of PHKCs when stimulated with paradigm hepatotoxicants. hPSC-KCs developed in this study offer a renewable human cell source for liver-specific macrophages which can be used to develop in vitro systems for modelling the inflammatory state of the liver.

Description
Recombinant baculoviral vectors efficiently transduce several types of cells in the brain. To characterize host responses to viral challenge, thus verifying the suitability of using the virus for the development of gene therapy strategies in the central nervous system, we used cDNA microarray technology to examine in vitro and in vivo global cellular gene expression profiles after viral transduction. We demonstrated that the transduction induced host antiviral responses as a major reaction in all three types of samples profiled, including the rat brain, cultured human astrocytes and human neuronal cells. The related genes were mainly those associated with innate immunity. Several genes of the major histocompatibility complex molecules, an important component of the host adaptive immunity to exogenous pathogens, were up-regulated in the rat brain and human astrocytes, but not in neuronal cells. We also observed that genes related to cell death and apoptosis were up-regulated and genes related cell cycle regulation were down-regulated in neuronal cells, but not obviously affected in astrocytes. These findings should be useful in understating the molecular basis for neural cell response to baculoviral transduction and guiding rational applications of baculoviral vectors in the central nervous systems
