Analysis of Oregon R animals treated with an ethylacetate extract from Piper nigrum seeds, natural pyrethrum, or both. Pyrethrum is an insecticide. The P. nigrum extract has insecticidal properties. The study examines the synergistic effect of both agents on gene expression.

(Submitter supplied) This experiment compared separate pools of Drosophila which received identical topical treatments of 99% ethanol 6 hours after exposure. The purpose of this was to assess the degree of natural variability that could be expected to be observed between samples in the absence of distince treatments. This was to allow for greater confidence in interpreting the results of other experiments which compared insects that received different treatments. more...

(Submitter supplied) The purpose of this experiment was to assess the effect of a synergistic combination of natural pyrethrin and an ethylacetate extract of Piper nigrum seeds (a botanical insecticide). This effect was compared to the effects of P. nigrum or pyrethrin used alone. Due to the synergistic nature of the mixture, it was predicted that gene expression profiles in this treatment would reflect this effect. Keywords: insecticide response, stress-response

(Submitter supplied) This experiment was intended to determine if topical exposure to ethanol led to significant changes in gene expression in adult Drosophila melanogaster. It was determined that topical exposure to ethanol did not lead to a strong differential expression of genes in Drosophila after 4 hours. Keywords: Ethanol response, stress response

(Submitter supplied) I hypothesized that social interactions, such as those involved in reproductive behaviors, would lead to immediate and assayable changes in gene expression that may have important effects on individual reproductive success and fitness through alterations in physiology or via short-term or long-term changes in nervous system function.

(Submitter supplied) Species often produce sterile hybrids early in their evolutionary divergence, and some evidence suggests that hybrid sterility may be associated with deviations or disruptions in gene expression. In support of this idea, many studies have shown that a high proportion of male-biased genes are underexpressed compared to non-sex-biased genes in sterile F1 male hybrids of Drosophila species. In this study, we examined and compared patterns of misexpression in 4 day old sterile male F1 hybrids of Drosophila simulans and its sibling species, D. more...

(Submitter supplied) Co-expression of genes that physically cluster together is a common characteristic of eukaryotic transcriptomes. Identifying these groups of co-expressed genes is important to the functional annotation of genomes and understanding the evolutionary fates of the clustered genes. We used microarrays to measure gene expression in seven closely related Drosophila species, to identify domains clusters within a species of Drosophila (D. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) PURPOSE. Triamcinolone acetonide (TA) and dexamethasone (DEX) are corticosteroids commonly used for ocular inflammation but both can cause ocular hypertension. We investigated the differential gene expression profile of human trabecular meshwork (TM) cells in response to treatment by TA compared to that by DEX. METHODS. Total RNA was extracted from cultured human TM cells treated with TA or DEX and used for microarray gene expression analysis. more...
