- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Pyrethroids are neurotoxicants that disrupt nervous system function by interacting with a variety of membrane bound ion channels on neuronal plasma membranes. This study is designed to investigate the transcriptional events downstream of pyrethroid-induced disruption of nervous system excitability. Adult, male Long-Evans rats were orally dosed in vivo with a single dose of either permethrin (1, 10, or 100 mg/kg) or deltamethrin (0.3, 1, 3 mg/kg) at levels that produce only modest behaviroal effects in the whole animal (Wolansky et al. 2006). Transcriptional profiles were obtained from frontal cerebrocortical tissue 6 hours after acute exposure. The primary goals were 1) to identify dose-responsive biomarkers of effect for pyrethroids and 2) identify sensitive intracellular signaling or metabolic pathways sensitive to pyrethroid compounds.
Publication Title
Transcriptional response of rat frontal cortex following acute in vivo exposure to the pyrethroid insecticides permethrin and deltamethrin.

Description
In order to identify genes that are activated in differentiating WT ESCs, but are missing in Tal-1-/- and Runx1-/- ESCs, and which might be involved in the generation of definitive hematopoietic progenitors and their specification thereafter, we performed microarray analyses on purified Flk-1+ cells, differentiated from these ESCs for 4, 5, and 6 days in vitro.

Description
Approximately 50% of patients with chronic hepatitis C (CHC) have a sustained virologic response (SVR) to treatment with pegylated interferon (pegINF)- and ribavirin. Non-response to treatment is associated with constitutively increased expression of IFN-stimulated genes (ISGs) in the liver. Treatment of patients with acute hepatitis C (AHC) is more effective, with SVR rates >90%. We investigated mechanisms of the different responses of patients with CHC and AHC to pegIFN- therapy. We analyzed IFN signaling and ISG expression in liver samples from patients with acute hepatitis C (AHC), patients with chronic hepatitis (CHC), and individuals without hepatitis C (controls) using microarray, immunohistochemical, and protein analyses. Findings were compared with those from primary human hepatocytes stimulated with IFN- or IFN-, as reference sets. Expression levels of 100s of genes, primarily those regulated by IFN-, were altered in liver samples from patients with AHC compared with controls. Expression of IFN-stimulated genes was induced in liver samples from patients with AHC, whereas expression of IFN-stimulated genes was induced in samples from patients with CHC. In an expression analysis of negative regulators of IFN- signaling, we did not observe differences in expression of SOCS1 or SOCS3 between liver samples from patients with AHC and those with CHC. However, USP18 (another negative regulator of IFN- signaling), was upregulated in liver samples of patients with CHC that did not respond to therapy, but not in AHC. In conclusion, differences in expression of ISGs might account for the greater response of patients with AHC, compared to those with CHC, to treatment with pegINF- and ribavirin. Specifically, USP18 is upregulated in liver samples of patients with CHC that do not respond to therapy, but not in patients with AHC.
