Project description:In order to understand the chronic hypoxia (CH) effect upon the absence of dystrophin, Drosophila melanogaster wild type and the model for DMD (dmDys), in which all dystrophins expression was knocked out by iRNA, were exposed to high altitude hypoxia (hypobaric hypoxia) during a 16-day climbing period reaching the summit of Mount McKinley (6194 meters above sea level). Furthermore, dmDys and Drosophila wild type were exposed to normobaric hypoxia (hypoxic chamber) following the same oxygen levels observed during the climbing expedition and to normoxic conditions for comparison. Affymetrix GeneChip® profiling was performed for individual flies from each experimental group. CH-dmDys differentially expressed 1281 genes, whereas control group differentially expressed 57 genes. Eight heat shock protein genes detected in the CH-dmDys microarray study were down-regulated, instead of up-regulated as seen in wild type hypoxic flies. This result suggests a differential gene expression response to CH, which could affect muscle performance.These results suggest that dmDys is more sensitive to CH due to reduced muscle function and hypoxic stress response.

Overall design: Adults wild type and dystrophic flies (3-5 days old) were exposed to hypobaric hypoxia for two weeks during the summer expedition to Mount McKinley, Alaska (6194 MASL). Another set of wild types and dystrophic flies were exposed to normobaric hypoxia according to the table I obtained during the climbing expedition. During the expedition, the flies were maintained in vials with regular molasses and covered by thermo isolation to avoid low temperature, keeping the temperature at 25C. The experiment performed in the laboratory also used vials with regular molasses and at 25C. Table I. Expedition log book for mount McKinley ascent.

Project description:Acute stress provides many beneficial effects whereas chronic stress contributes to a variety of human health problems. The objective of this study was to use a rodent model to uncover hippocampal gene signatures associated with prolonged chronic stress which could potentially serve as biomarkers and therapeutic targets for early diagnosis and pharmacological intervention for stress induced disease. Mice were subjected to restraint stress over 7 consecutive days and gene expression changes in the hippocampus were analyzed at 3, 12 and 24 hours following the final restraint treatment. Data indicated that mice exposed to chronic restraint stress exhibit a differential gene expression profile compared to non-stressed controls. The greatest differences were observed 12 and 24 hrs following the final stress test.

Project description:In order to study the gene expression profile in C57Bl/10 mouse blood, we exposed three different groups of animals. First was exposed to PO2 21% or normoxia. The second was exposed to chronic hypoxia (from PO2 21% to PO2 8%) and the third was also exposed to the same chronic hypoxia (CH) protocol but followed by two weeks under normoxia, and called as recovery group. The blood was extracted from inferior vena cava, the RNA was extracted, amplified and hybridized to Affimetrix MOE 430 V2.o chip. The results were analyzed using Partek Genome suite software. Using two fold cuttoff and 0% FDR parameters, we observed genes 512 diferentially expressed, of which one gene was up-regulated in both hypoxic and recovery condition, 202 were up-regulated during CH and then down-regulated after the recovery, 18 genes were down-regulated afteh CH and the up-regulated after recovery, ans finally 9 genes were down-regulated in both CH and recovery conditions. Each group of C57Bl/10 mouse had 4 individuals and they were divided into three different groups of animals. First was exposed to PO2 21% or normoxia for 14 days. The second was exposed to chronic hypoxia (from PO2 21% to PO2 8%) and the third was also exposed to the same chronic hypoxia (CH) protocol but followed by two weeks under normoxia, and called as recovery group. After the exposure period, the animals were anaesthetized with a mix of Ketamine (100 mg/mL) and xylasine (20 mg/mL) in a proportion of 1:1. A incison was made on abdominal area and from kidneis and liver area of inferior vena cava venus blood was collected The blood was extracted from inferior vena cava. Then, the RNA was extracted, amplified and hybridized to Affimetrix MOE 430 V2.o chip. The results were analyzed using Partek Genome suite software. Using two fold cuttoff and 0% FDR parameters, we observed genes 512 diferentially expressed, of which one gene was up-regulated in both hypoxic and recovery condition, 202 were up-regulated during CH and then down-regulated after the recovery, 18 genes were down-regulated afteh CH and the up-regulated after recovery, ans finally 9 genes were down-regulated in both CH and recovery conditions.

Project description:Regulatory T (Treg) cells act as terminators in the case of T cell immunity during the acute phase of viral infection. However, their roles in chronic viral infection are not completely understood. We compared the phenotype and function of Treg cells during acute and chronic viral infection using lymphocytic choriomeningitis virus-infected mouse models. Chronic infection, unlike acute infection, led to induction of Treg cells and upregulation of various inhibitory receptors. Treg cells isolated from chronically infected mice (chronic Treg cells) displayed greater suppressive capacity for inhibiting T cell proliferation and subsequent cytokine production than those from naM-CM-/ve (naive Treg cells) or acutely infected mice (acute Treg cells). These gene expression profiles provided evidence that chronic Treg cells display characteristics distinct from either naive or acute Treg cells. Mouse splenic CD4+CD25+ regulatory T cells were analyzed at 0 day and 16 day after acute or chronic viral infection with LCMV Arm or CL13, respectively.

Project description:Using a novel flood source construct, we performed a direct comparison of genome-wide gene expression regulations resulting from exposure of primary human prostate fibroblast cultures to acute (10cGy and 200cGy) and longer-term chronic (1.0-2.45cGy cumulative over 24hr) exposures. Samples were collected at 24 hours after an acute 10cGy or 200cGy exposure (48cGy per minute) versus immediately after an accumulated 24 hour chronic 1.0 to 2.45cGy low dose-rate exposure (7 to 17M-BM-5Gy per minute). Control 0cGy samples were collected at the same time. A total of 4 independent experimental replicates were used for each sample resulting in (2 individuals M-CM-^W 4 experimental conditions M-CM-^W 4 experimental replicates) 32 microarrays.
