Temporal gene regulation of human hepatocellular carcinoma HepG2 cells treated with obacunone

ABSTRACT: Obacunone treatment slightly changes gene expression of cholesterol metabolism-associated genes in HepG2 cells Total RNA obtained from HepG2 cells treated with 100 uM obacunone for 0.5, 1, 3, 6, or 12 h was compared to that of vehicle control cells.

ChIP-seq analysis of LSD2/DNA interaction in HepG2 cells in normal condition

Project description:ChIP-seq analysis of HepG2 cells revealed that many of the target genes of LSD2 were related to lipid metabolism. We found that LSD2 is an important epigenetic regulator of hepatic lipid metabolism. Examination of LSD2/DNA interaction in HepG2 cells in normal condition.

Effect of obacunone on Salmonella Typhimurium transcriptome

Project description:Obacunone is a limonoids present in Citrus species. We previously reported that obacunone was inhibitory to the cell-cell signaling in Vibrio harveyi and Escherichia coli O157:H7. In the present work we evaluated the effect of obacunone on the food borne pathogen Salmonella Typhimurium LT2 using cDNA microarray. The results demonstrate that obacunone exerts an antivirulence effect on S. Typhimurium LT2 by repressing SPI1 and SPI2. Furthermore, the effect of obacunone seems to be dependent upon EnvZ. One condition experiment, obacunone treated versus DMSO treated. Biological replicates: 3 control, 3 treatment, hybridized in dye-swapped design

DNA microarray analysis for HepG2 cells exposed to arsenic trioxide

Project description:DNA microarray analysis revealed that the genes related to cell cycle regulation were significantly induced at non- and sub-lethal concentrations (i.e., 0.05-6 M-BM-5M), while the common feature of heavy metal toxicity such as oxidative damage and following increase in glutathione, heat shock proteins, and metallothionein were confirmed at high concentrations (i.e., 6-40 M-BM-5M). The concentration dependent modulation of gene expression (induction of cell cycle genes, induction of cell cycle arrest genes and apoptotic genes) following exposure to arsenic was further supported by acceleration of cell proliferation, ROS generation, and cytotoxicity. Furthermore, three cell cycle genes (i.e., CDC25B, UBE2C, and PTTG1) were proposed as marker genes of inorganic arsenic exposure. Those results indicated the potential pro-carcinogenic actions of inorganic arsenic occur in environmentally relevant exposures (as low as 0.07 M-BM-5M). In this study, we examined the gene expression alteration in HepG2 cells exposed to arsenic trioxide (5 nM to 40 M-BM-5M as As2O3 for 48 hours) by DNA microarray with 8795 human genes. HepG2 cells were also exposed to M-NM-5-caprolactam as a reference of non carcinogen since it is the only chemical categorized in IARCM-bM-^@M-^Ys group 4 (Probably Not Carcinogenic). MQ water was used as control. For replicate, three dishes were prepared for each sample and individually treated in parallel.

Effect of chlorination on toxicity of wastewater effluents from different treatment systems to HepG2 human hepatoma cells

Project description:Effect of chlorination on the toxicity of wastewater effluents treated by activated sludge (AS) and submerged membrane bioreactor (S-MBRB) systems to HepG2 human hepatoblastoma cells was investigated. In addition to cytotoxicity assay, the DNA microarray-based transcriptome analysis was performed to evaluate the change in modes of toxic actions (MOAs) of effluents by chlorination. Effluent organic matters (EfOM) and disinfection by-products (DBPs) were characterized by using Fourier transform mass spectrometry (FT-MS). The cytotoxicity of AS effluent was elevated by chlorination, while the toxicity of S-MBRB effluent was reduced. The averaged O/C ratio of EfOM in S-MBRB effluent was lower than that in AS effluent. The results of the transcriptome and FT-MS analyses suggested that lower O/C molecules influenced on M-bM-^@M-^\response to hormone stimulusM-bM-^@M-^] and M-bM-^@M-^\acute inflammatory responseM-bM-^@M-^] but those were decreased by chlorination, which consequently reduced cytotoxicity. On the other hand, larger number of DBPs and other molecules were increased in AS effluents by chlorination. Those molecules might influence on M-bM-^@M-^\cellular metabolic processM-bM-^@M-^], which consequently elevated cytotoxicity. Therefore, the combination of the toxicity assays and chemical analysis demonstrated the changes in severity of cytotoxicity and MOAs by chlorination, and the difference of chemical characteristics which relate to those toxicity changes. We examined the gene expression alteration in human hepatoma cell line, HepG2 exposed to the chlorinated wastewater effluents from membrane bioreactor and the activated sludge process. Human Genome Focus Array, which represents 8,795 verified human sequences, was used. All effluent samples were concentrated by using solid phase extraction (SPE). SPE fraction from MQ water was used as controll. For duplicate, two dishes were prepared for each sample and individually treated in parallel.

Expression analysis of HepG2, HepG2-slug and HepG2-slug on Matrigel

Project description:Investigation of whole genome gene expression level changes in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel. Whole genome gene expression level changes have been compared in hepatocellular carcinoma cell line hepG2 in regular culture, hepG2-slug in regular culture and hepG2-slug on Matrigel. Roche NimbleGen micro-array analysis was employed to assess global genome expression in HepG2 in regular culture, HepG2-slug in regular culture and HepG2-slug on Matrigel. The results demonstrated that the up-regulated genes and the down-regulated genes increased significantly when HepG2-slug cells with VM forming ablity were cultured on Matrigel and formed VM.
