Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We performed gene expression profiling of oligooxopiperazines (OPs) targeting the hypoxia-inducible transcription factor complex. Treatment of cells with OPs inhibited hypoxia-inducible gene expression in A549 cells.
Publication Title

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
The mucosa that lines the gastrointestinal (GI) tracts is an important portal of entry for pathogens and provides the frontline of immune defense against HIV infection. Epithelial barrier dysfunction during HIV infection has largely been attributed to the rapid and severe depletion of CD4 T cells in the gastrointestinal (GI) tract. In this study, the poential role of small non-coding microRNA (miRNA) to contribute to epithelial dysfunction was investigated in the non-human primate SIV model and microarrays were utilized to determine changes in mucosal gene expression (non-miRNA) that could be correlated to miRNA modulatiolns.
Publication Title
Intestinal epithelial barrier disruption through altered mucosal microRNA expression in human immunodeficiency virus and simian immunodeficiency virus infections.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The role of estrogen and testosterone in the regulation of gene expression in the proximal reproductive tract is not completely understood. To address this question, mice were treated with testosterone or estradiol and RNA from the efferent ducts and caput epididymis was processed and hybridized to Affymetrix MOE 430 2.0 microarrays. Analysis of array output identified probe sets in each tissue with altered levels in hormone treated versus control animals. Hormone treatment efficacy was confirmed by determination of serum hormone levels pre- and post-treatment and observed changes in transcript levels of previously reported hormone-responsive genes. Tissue-specific hormone sensitivity was observed with 2867 and 3197 probe sets changing significantly in the efferent ducts after estrogen and testosterone treatment, respectively. In the caput epididymis, 117 and 268 probe sets changed after estrogen and testosterone treatment, respectively, demonstrating a greater response to hormone in the efferent ducts than the caput epididymis. Transcripts sharing similar profiles in the intact and hormone-treated animals compared with castrated controls were also identified. Ontological analysis of probe sets revealed a significant number of hormone-regulated transcripts encode proteins associated with lipid metabolism, transcription and steroid metabolism in both tissues. Real-time RT-PCR was employed to confirm array data and investigate other potential hormone-responsive regulators of proximal reproductive tract function. The results of this work reveal previously unknown responses to estrogen in the caput epididymis and to testosterone in the efferent ducts as well as tissue specific hormone sensitivity in the proximal reproductive tract.

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
We used the ileal loop model to assess the effects of enteric bacteria organisms on host gene expression in intestinal tissue independent of and following early SIV infection. SIV infection in the gut causes rapid and severe immune dysfunction and damage to the intestinal structure, this may alter the intimate interaction with lumenal organisms. This study was performed to determine whether early SIV infection, prior to the depletion of CD4+ T cells, can alter interaction of the host with pathogenic Salmonella serovar Typhimurium (ST) or commensal Lactobacillus plantarum (LP), and to further understand the earliest changes to the intestinal mucosa following SIV infection.
Publication Title
Early mucosal sensing of SIV infection by paneth cells induces IL-1β production and initiates gut epithelial disruption.
