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.

Project description:Gene expression profile at single cell level of whole lung cells from C57BL/6J mice or global STING knock-out mice (STING-/-), exposed to either room air or chronic hypoxia (4-week 10% oxygen). Study described in manuscript "A non-inteferon role of STING in pulmonary hypertension". We used scRNAseq to analyze the difference in pulmonary cells and different gene expression across populations between wild type and STING-/- underwent pulmonary hypertension induction with chronic hypoxia.

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.

Project description:To determine hypoxia mediated changes in whole blood, normal C57Bl/10 mice were gradually exposed to a chronic hypoxic environment, equivalent to an altitude of 6500m, for 2 weeks in vivo. Control, age-matched mice were maintained under normoxic, normobaric conditions by exposing them to ambient air in Philadelphia (c. 50 mts above sea level).

Project description:To determine hypoxia mediated changes in whole blood, normal C57Bl/10 mice were gradually exposed to a chronic hypoxic environment, equivalent to an altitude of 6500m, for 2 weeks in vivo. Control, age-matched mice were maintained under normoxic, normobaric conditions by exposing them to ambient air in Philadelphia (c. 50 mts above sea level). Purpose: To determine the expression profile of genes differentially expressed in mouse whole blood upon exposure to normobaric hypoxia in vivo. Methods: The hypoxic group consisting of 6 C57/BL10 mice was exposed to normobaric hypoxia, in a specially designed and hermetically closed hypoxic chamber, using a gas mixing system Pegas 4000 MF (Columbus Instruments, Ohio, USA). The oxygen level was decreased from 21% to 8% over a period of 14 days. 6 control mice were kept at normal oxygen and pressure levels by exposing them to ambient air in Philadelphia (c. 50 mts above sea level). RNA from whole blood was isolated, processed and used for microarray-based expression profiling. Profiles were generated for genes differentially expressed at control versus normobaric hypoxia in whole blood using a false discovery rate (FDR) of 0%. The Profile was validated by real-time quantitative reverse transcription-polymerase chain reaction (qPCR) on 2 biologically independent samples, not used for generating the profile. Results: The transcriptomes associated with normobaric hypoxia in whole blood were identified. We found 4723 genes that were differentially expressed in normobaric hypoxic whole blood compared to control with a 0% FDR and a 2 fold cutoff. Conclusion: Transcriptome level differences exist in the whole blood of animals subjected to normobaric hypoxia. Our definition of the normobaric hypoxia blood transcriptome provides insight into the functioning and response to hypoxia in whole blood.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
