Description
Analysis of whole genome expression changes in livers from wild type animals and animals with a liver specific transgenic over expression of Cyp7a1. Mice were given a chronic, repetitive administration of LPS for 7 days. Our prior analysis had indicated that inflammation suppresses Cyp7a1 and that this leads to accumulation of intermediates in the mevalonate biosynthesis pathway. Here, we hypothesized that over expression of Cyp7a1 would not affect the changes in transcriptional state due to chronic administration of LPS. We provide gene expression data which evaluates this question. Here we find that over expression of Cyp7a1 minimally alters the transcriptome of livers in an untreated state, and that it has small effects on the response to chronic LPS. Overall design: Total RNA isolated from livers of wild type and liver specific Cyp7a1 transgenic animals treated with or without recurrent, daily LPS injections (1.5mg/kg) for 7 days. There are two biological replicates per condition. Samples are a matrix of all conditions reported as FPKMs.

Description
Analysis of whole genome expression changes in primary hepatocytes in response to chronic stimulation with inflammatory cytokines. We hypothesized that chronic treatment of primary hepatocytes with TNF would result in a reprogramming of the cell's transcriptome to improve adaptation to the presence of a chronic inflammatory stress. Here we provide expression analysis detailing genes upregulated, downregulated, and unchanged after 2 days of TNF treatment. We have included gene expression profiling of cells treated with TNF for 2 hours to help isolate the changes unique to chronic TNF treatment of primary hepatocytes.

Description
Cellular dedifferentiation signifies the withdrawal of cells from a specific differentiated state into a stem cell-like undifferentiated state. However, the mechanism of dedifferentiation remains obscure. We showed that mature adipocytes (MA) and follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency.

Description
Significant qualitative and quantitative differences exist between humans and the animal models used in research. However, significant quantitative and qualitative differences exist between humans and the animal models used in research. This is as a result of genetic variation between human and the laboratory animal. Therefore the development of a system that would allow the assessment of all molecular differences between species after drug exposure would have a significant impact on drug evaluation for toxicity and efficacy. Here we describe a cross-species microarray methodology that identifies and selects orthologous probes after cross-species sequence comparison to develop an orthologous cross-species gene expression analysis tool. The assumptions made by the use of this orthologous gene expression strategy for cross-species extrapolation is that; conserved changes in gene expression equate to conserved pharmacodynamic endpoints. This assumption is supported by the fact that evolution and selection have maintained the structure and function of many biochemical pathways over time, resulting in the conservation of many important processes. We demonstrate this difference using a cross-species methodology by investigating species specific differences of the peroxisome proliferator activator receptor (PPAR) alpha in rat and human.
