Affymetrix Drosophila Genome Array (drosgenome1)
Description
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.

Description
Determination of the genes regulated by ERRalpha nuclear receptor in MDA-MB231 cells Overall design: MDA-MB231 cells were inactivated for ERRalpha using siRNA. Three different siRNAs were used (siE1, siE2, siE3). Cells treated with a control siRNA (siC samples) were used for comparison. Duplicate samples were analyzed. Transcriptomic analysis was performed by RNA-Seq

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
Retinoic acid (RA) and 2,3,7,8-tetrachlorodibenzo-p-dioxin activate distinct ligand-dependent transcription factors, and both cause cardiac malformation and heart failure in zebrafish embryos. We hypothesized that they cause this response by hyperactivating a common set of genes critical for heart development. To test this, we used microarrays to measure transcripts changes in hearts isolated from zebrafish embryos 1,2,4 and 12 h after exposure to 1M RA. We used hierarchical clustering to compare the transcriptional responses produced in the embryonic heart by RA and TCDD. We could identify no early responses in common between the two agents. However, at 12 h both treatments produced a dramatic downregulation of a common cluster of cell cycle progression genes, which we term the Cell Cycle Gene Cluster (CCGC). This was associated with a halt in heart growth. These results suggest that RA and TCDD ultimately trigger a common transcriptional response associated with heart failure, but not through the direct activation of a common set of genes. Among the genes rapidly induced by RA was Nr2F5, a member of the COUP-TF family of transcription repressors. We found that induction of Nr2F5 was both necessary and sufficient for the cardiotoxic response to RA.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
A microarray study of sex- and gonad-biased gene expression was conducted to determine whether zebrafish demonstrate male-specific patterns consistent with those observed in other animals. We identified a large number of genes (5899) demonstrating statistical differences in transcript abundance between male and female Danio rerio. All sex-biases in gene expression were due to differences between testis and ovary, although differences between male and female body likely went undetected due to constraints imposed by study design and statistical criteria. Male-enriched genes were more abundant than female-enriched genes, and the magnitude of expression bias for male-enriched genes was greater than that for female-enriched genes. We also identified a large number of candidate reproductive genes based on elevated transcript abundance in testes and ovaries, relative to male body and female body, respectively. Gene expression patterns in adult zebrafish from this study are consistent with the male-biased patterns typical of most animal taxa studied to date. Recent zebrafish studies designed to address more specific questions have not reported the same findings, but major methodological and analytical differences across these studies could explain discrepancies.
