Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The present study was constructed to confirm previous findings that mice on a high fat diet (HFD) treated by subcutaneous injection with exenatide (EXE) at 3g/kg once daily for 6 weeks develop exocrine pancreatic injury (Rouse et al. 2014). The present study included 12 weeks of EXE exposure at multiple concentrations (3, 10, or 30 g/kg) with multiple endpoints (histopathology evaluations, immunoassay for cytokines, immunostaining of the pancreas, serum chemistries and measurement of trypsin, amylase, and, lipase, and gene expression profiles). Time- and dose-dependent exocrine pancreatic injury was observed in mice associated with EXE exposure in a HFD environment. The time- and dose-dependent morphological changes identified in the pancreas involved acinar cell injury and death (autophagy, apoptosis, necrosis, and atrophy), cell adaptations (hypertrophy and hyperplasia), and cell survival (regeneration) accompanied with varying degrees of inflammatory response leading to secondary injury in pancreatic blood vessels, ducts, and adipose tissues. Gene expression profiles supported the presence of increased signaling for cell survival and altered lipid metabolism. The potential for EXE to cause acute or early chronic pancreatic injury was identified in a HFD environment. In human disease, the influence of pancreatitis risk factors or pre-existing chronic pancreatitis on this injury potential requires further investigation.

- Affymetrix Rat Genome U34 Array (rgu34a)
Description
This study was initiated to characterize early DOX-induced changes in cardiac gene expression in order to identify potential additional areas for clinical intervention. Male spontaneously hypertensive rats (SHR) received 3 mg/kg DOX or vehicle (iv) 30 minutes following pretreatment with 50 mg/kg DZR or saline (ip) weekly for 1, 2 or 3 weeks.

- Affymetrix C. elegans Genome Array (celegans)
Description
We exposed wild-type Vibrio cholerae E7496, multiple Vibrio cholerae virulence factor deleted genes with intact hemolysin A gene [CVD109] and without hemolysin A gene [CVD110] in E7946, and E.coli OP50 to wild-type C.elegans N2 for 18 hours. We used microarrays to detail the global gene expression and identified distinct classes of up-regulated and down-regulated genes during this process.

- Affymetrix Human Gene 2.1 ST Array (hugene21st)
Description
The study of the compond PIP-RBPJ-1 function on neural stem cell. Synthetic DNA-binding inhibitors capable of gaining precise control over neurogenesis factors could obviate the current clinical barriers associated with small molecule use in regenerative medicine. Here, we show the design and bio-efficacy of a synthetic ligand PIP-RBPJ-1 to cause promoter-specific suppression of neurogenesis-associated HES1, and its downstream genes. Furthermore, PIP-RBPJ-1 alone could alter the neural system-associated notch signaling factors and remarkably induce neurogenesis with an efficiency that is comparable to a conventional approach. Here is one day treatment of the PIP-RBPJ-1 on neural stem cells.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
Human cytomegalovirus (HCMV) induces pro-inflammatory monocytes following infection and we have evidence that EGFR is a key mediator in this early activation. To begin to address how this signalling pathway is responsible for the rapid activation of infected monocytes, we examined the role this pathway played in the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of genes, including inflammatory genes, were regulated in a EGFR-dependent manner, identifying this pathway as a key cellular control point in the conversion of monocytes to an activated pro-inflammatory state following HCMV infection.
Publication Title
Activation of EGFR on monocytes is required for human cytomegalovirus entry and mediates cellular motility.

Description
Human cytomegalovirus induces a pro-inflammatory monocyte following infection and we have evidence that NF-B and phosphatidylinositol 3-kinase [PI(3)K] are key mediators in this early activation. To begin to address how these signalling pathways are responsible for the rapid activation of infected monocytes, we examined the role these pathways played in the transcriptome of infected monocytes. Global transcriptional profiling using cDNA microarrays revealed a significant number of genes, including inflammatory genes, were regulated in a NF-B- and/or PI(3)K-dependent manner, identifying these pathways as key cellular control points in the conversion of monocytes to an activated pro-inflammatory state following HCMV infection.
