Description
It is known from the transcriptomic studies that the effects of aging are tissue specific. It has shown that the neuronal Gclc overexpression in D. melanogaster increased lifespan and improved certain physiological parameters associated with health benefits (locomotor activity, circadian rhythmicity and stress resistance).Sarcopenia is aging-related life-threatened condition and its mechanisms are important for future prevention and treatment. The purpose of the present study was to investigate the effects of the neuronal GclC overexpression on gene expression levels in imago thorax, which is primarily composed of muscles.

Affymetrix Yeast Genome S98 Array (ygs98)
Description
In response to limited nitrogen and abundant carbon sources, diploid Saccharomyces cerevisiae strains undergo a filamentous transition in cell growth as part of pseudohyphal differentiation. Use of the disaccharide maltose as the principal carbon source, in contrast to the preferred nutrient monosaccharide glucose, has been shown to induce a hyper-filamentous growth phenotype in a strain deficient for GPA2 which codes for a Galpha protein component that interacts with the glucose-sensing receptor Gpr1p to regulate filamentous growth. In this report, we compare the global transcript and proteomic profiles of wild-type and Gpa2p deficient diploid yeast strains grown on both rich and nitrogen starved maltose media. We find that deletion of GPA2 results in significantly different transcript and protein profiles when switching from rich to nitrogen starvation media. The results are discussed with a focus on the genes associated with carbon utilization, or regulation thereof, and a model for the contribution of carbon sensing/metabolism-based signal transduction to pseudohyphal differentiation is proposed.

Description
Chlorpyrifos is an organophosphorus insecticide that despite imposed restricitions on its use by the EPA, is one of the most commonly used insecticides. Although CPF is so widely used little is known about its effect on overall gene expression in vivo.
Publication Title
Subtoxic chlorpyrifos treatment resulted in differential expression of genes implicated in neurological functions and development.

Description
In order to examine the long term effects of the OPs, murine liver cells (BNL CL.2, ATCC TIB-73) have been exposed to sub-lethal doses of three OPs: diisopropylfluorophosphate (DFP) representative of sarin and soman, O,S-diethyl methylphosphonothioate (OSD) serving as a simulant for VX, and paraoxon as an example of OP insecticides. Dosing levels of these compounds was set at 20% of the IV LD50 for each, with a 4 hour exposure time. Gene arrays and physiological tests were run at three time points following exposure; 2 hours, 2 days, and 2 weeks. The physiological results showed little to no effect upon exposure to sub-lethal dose of OPs. Gene expression and microRNA (miRNA) profiles using GeneChip Mouse Gene 1.0 ST arrays and miRNA arrays (Affymetrix, Santa Clara, CA) found that the OPs did alter expression of genes related to several systems previously implicated in OP exposure with no long term effects. In addition, a significant number of sRNA/snRNA and ribosomal RNA were found to be affected suggesting the need for further study of the changes in these regulators.

Description
Several different mechanisms have been proposed to explain the possible role of cranberries, cranberry juice, and cranberry extracts in inhibiting bacterial growth. In this report, we showed that Escherichia coli showed slower growth rate in response to the presence of cranberry juice in the growth media. By compareing the global transcript profiles, significant modulation of several genes of E. coli grown in LB broth with 10% cranberry juice were identified and provided identification of the potential mechanisms involved in the inhibitory effects of cranberry juice. The results presented clearly demonstrate that the inhibitory effect on bacterial growth observed in the presence of cranberry juice/extracts is primarily a result of the iron chelation capacity of PACs and direct disruption of metabolic enzymes. The results are discussed with a focus on the genes associated with iron chelation capability.

Description
The zoonotic pathogen, Streptococcus suis, has been demonstrated to use the choroid plexus as an entry gate into the central nervous system, where it can induce meningitis. The global transcriptome of primary porine and immortal human choroid plexus epithelial cells, which were infected in vitro with S. suis, was analyzed via RNA-seq. Additionally, the choroid plexus was isolated from pigs experimentally infected in vivo with S. suis and who either suffered from meningitis or were meningitis-free. These tissue samples were also subject of global transcriptomee analysis via RNA-seq.
