We used microarrays to characterize transcriptome profiles of rat vocal fold tissue following surgical injury (vs. naive tissue); rat vocal fold fibroblasts harvested from scar tissue at the 60 d time point (vs. naive fibroblasts); rat vocal fold scar fibroblasts treated with siRNA against the collagen chaperone protein rat gp46 (vs. scramble siRNA).
Microarray-based characterization of differential gene expression during vocal fold wound healing in rats.

View SamplesColorectal cancer often arises from adenomatous polyps. Polyps can grow and progress to cancer, but may also remain static in size, regress, or resolve. Prediciting which progress to cancer and which remain benign is difficult. We developed a long-lived murine model of colorectal cancer with tumors that can be followed by colonoscopy. Our aim was to assess whether these tumors have similar growth patterns and histologic fates to human colorectal polyps to identify features to aid in risk stratification of colonic tumors.

View SamplesTo investigate the early host response triggered by three different strains of Trypanosoma cruzi at a local infection site, changes in host gene expression were monitored in a murine intradermal infection model using Affymetrix oligonucleotide arrays. Robust induction of IFN-stimulated genes (ISGs) was observed in excised skin 24 hours post-infection where the level of ISG induction was parasite strain-dependent with the least virulent strain triggering a muted IFN response. Infection of mice immunodepleted of IFN-producing cells or infection of IFN-deficient mice had minimal impact on the IFN response generated in T. cruzi infected mice. In contrast, infection of mice lacking the type I IFN receptor demonstrated that type I IFNs are largely responsible for the IFN response generated at the site of infection. These data highlight type I IFNs as important components of the innate immune response to T. cruzi the site of inoculation and their role in shaping the early transcriptional response to this pathogen.

View SamplesAdiponectin is an adipose-derived hormone with anti-inflammatory activity. Following subacute ozone exposure (0.3 ppm for 24-72 h), pulmonary neutrophilic inflammation is augmented in adiponectin deficient mice. The purpose of this study was to use microarrays to examine the impact of adiponectin deficiency on changes in pulmonary gene expression induced by ozone, a common air pollutant.

View SamplesObese mice have an augmented response to Ozone exposure (2 ppm for 3 hours and studied 24 hours later), including increase airway hyperresponsiveness and BAL inflammation when compared to WT ozone exposed mice. When IL-17A is block with systemic injected of IL-17A antibodies there is a decrease of response in the obese mice. To determine the mechanism of action, RNA was extracted from the lungs of IL-17A and Isotype injected ozone exposed obese mice and microarray analysis of gene expression was performed.

View SamplesObesity-associated metabolic complications are generally considered to emerge from abnormalities in carbohydrate and lipid metabolism, whereas the status of protein metabolism is not well studied. Here, we performed comparative polysome and associated transcriptional profiling analyses to study the dynamics and functional implications of endoplasmic reticulum (ER)-associated protein synthesis in the mouse liver under conditions of obesity and nutrient deprivation.
Polysome profiling in liver identifies dynamic regulation of endoplasmic reticulum translatome by obesity and fasting.

View SamplesWe hypothesize that gene expression in the Type II cells of Nrf2+/+ and Nrf2-/- mice are divergent thus contributing the cell growth. More specifically, type II cells from Nrf2-/- mice have increased reactive oxygen species that cause the impaired cell growth. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between Nrf2+/+ and Nrf2-/- cells.
