Burn injury remains a major clinical challenge to both survival and to quality of life. Its progressive, aberrant inflammation underlies the lethal dysfunction of various organs and the pain it induces is excruciating and notoriously difficult to manage. While it is known that burn injury's complex local and disseminating pathology is orchestrated from the burned tissue, few studies have sought to characterise the local signalling environment. An enhanced understanding of the local and acutely temporally-dynamic processes defining burn injury and its progression is required for the development of novel therapeutic interventions. Microdialysis was used as an interstitial sampling technique, conducted over three hours post-burn. Samples were analysed by metabolomics and a multiplex cytokine immunoassay. Next-Generation sequencing libraries of the burn and control microdialysis sites were prepared to measure transcriptional changes potentially underlying the interstitial profile characterising burn injury. Overall design: All microdialysis sites in the study were excised for the extraction of RNA; 4 burn site and 4 control site samples were analysed.

View SamplesIn this study, we investigate the anti-aging response induced by dietary restriction (DR) on gene expression level. For this, we carried out Ribosomal RNA depleted Total RNA sequencing in 16 weeks old Ercc1?/- ad libidum (AL), DR and wt mice. Overall design: Total RNA was extracted from fresh liver samples from 16 weeks old Ercc1?/- AL, DR and wt mice. Ribosomal RNA was depleted from the extracts by using RiboMinus kit (Ambion) then sequenced according to the Illumina TruSeq v3 protocol on HiSeq2000 platform.

View SamplesInbred congenic strain B6.C6.132.54/Vad was created using C57BL/6ByJ background and BALB/cJ donor strains. Flanking background markers at chr. 6: 75.9 Mb (rs4226008, NCBI Mouse Build 36 / dbSNP Build 126) and 122.3 Mb (rs3023093), and limiting donor markers at 81.9 Mb (rs4226024) and at 91.8 Mb (rs3712161) defined the introgressed region. We concluded the segment size must be between 9.9 Mb and 46.4 Mb. In a Quantitative Trait Gene identification study we compared brain (without cerebellum) gene expression between progenitors and congenics. Such comparisons can facilitate identification of cis-regulated genes and to establish genetic control of a complex phenotype whose expression is associated with the introgressed chromosome segment.
