To understand the transcriptional program by which GR regulates skin development, we performed a microarray analysis using the skin of E18.5 GR-/- and GR+/+ mouse embryos.

View SamplesWe report liver transcript profiling by RNA sequencing of Atp7b-/- and wild type mice at six weeks of age. Transcriptional network analysis of RNA-seq data reveals a highly interconnected network of transcriptional activators with over-representation of zinc-dependent and zinc-responsive transcription factors. Overall design: Wild type and Atp7b-/- Mice were maintained on strain C57BL x 129S6/SvEv. Housing was in shoebox cages and fed Mazuri Rodent diet (PMI Nutrition, Inc., Richmond, Indiana), containing 16 ppm Cu, 100 ppm Zn, and 235 ppm Fe and water ad libitum, with a 12-hour light/dark cycle. Six-week-old mice of both sexes were used for transcriptomic studies. Animals were sacrificed by carbon dioxide asphyxiation and liver tissue was harvested for RNA isolation. RNA sequencing was performed at the National Center for Genome Resources (NCGR) using the GAIIx platform. Average read quality was 38. An initial dataset was generated using two wild type and two Atp7b-/- samples with singleton 1x54 runs with 15,823,058; 8,149,631; 22,931,967 and 9,538,147 reads. A second paired end (2x54) dataset was generated to augment the initial singleton dataset with one wild type and one Atp7b-/- run resulting in 36,360,686 and 38,366,743 reads, respectively.

View SamplesSeveral reports have focused on the identification of biological elements involved in the development of abnormal systemic biochemical alterations in chronic kidney disease, but this abundant literature results most of the time fragmented. To better define the cellular machinery associated to this condition, we employed an innovative high-throughput approach based on a whole transcriptomic analysis and classical biomolecular methodologies. The genomic screening of peripheral blood mononuclear cells revealed that 44 genes were up-regulated in both chronic kidney disease patients in conservative treatment (CKD, n=9) and hemodialysis (HD, n=17) compared to healthy subjects (NORM) (p<0.001, FDR=1%). Functional analysis demonstrated that 11/44 genes were involved in the oxidative phosphorylation system (OXPHOS). Western blotting for COXI and COXIV, key constituents of the complex IV of OXPHOS, performed on an independent testing-group (12 NORM, 10 CKD and 14 HD) confirmed the elevated synthesis of these subunits in CKD/HD patients. However, complex IV activity was significantly reduced in CKD/HD patients compared to NORM (p<0.01). Finally, CKD/HD patients presented higher reactive oxygen species and 8-hydroxydeoxyguanosine levels compared to NORM. Taken together these results suggest, for the first time, that CKD/HD patients may have an impaired mitochondrial respiratory system and this condition may be both the consequence and the cause of an enhanced oxidative stress.

View SamplesWe provide a map of human ILC heterogeneity across multiple anatomical sites. Tissue-specific distinctions are particularly apparent for ILC1 populations, whose distribution was markedly altered in obesity or aging. Furthermore, the degree of ILC1 population hetero- geneity differed substantially in lymphoid versus mucosal sites. Together, these analyses comprise a comprehensive characterization of the spatial and temporal dynamics regulating the anatomical distri- bution, subset heterogeneity, and functional poten- tial of ILCs in non-diseased human tissues. Overall design: We present a quantitative analysis of ILC distribution and heterogeneity in lymphoid, mucosal, and metabolic tissues obtained from a diverse cohort of 44 previously non-diseased organ donors over a wide range of ages and body mass indexes (BMIs).
