Description
The polytrauma (PT) murine model has unique transcriptomic responses 2 hrs, 1 day and 3 days after injury. We determined with this clinically relevant model that the increased morbidity in the elderly is secondary to a failure of bone marrow progenitors, blood neutrophils, and bronchoalveolar lavage cells to initiate and complete an 'emergency myelopoietic' response, engendering myeloid cells that fail to clear secondary infection. In addition, the elderly appear unable to effectively resolve their inflammatory response to severe injury.

Description
Ribosome assembly in eukaryotes involves the activity of hundreds of assembly factors that direct the hierarchical assembly of ribosomal proteins and numerous ribosomal RNA folding steps. However, detailed insights into the function of assembly factors and ribosomal RNA folding events are lacking. To address this, we have developed ChemModSeq, a method that combines structure probing, high throughput sequencing and statistical modeling, to quantitatively measure RNA structural rearrangements during the assembly of macromolecular complexes. By applying ChemModSeq to purified 40S assembly intermediates we obtained nucleotide-resolution maps of ribosomal RNA flexibility revealing structurally distinct assembly intermediates and mechanistic insights into assembly dynamics not readily observed in cryo-electron microscopy reconstructions. We show that RNA restructuring events coincide with the release of assembly factors and predict that completion of the head domain is required before the Rio1 kinase enters the assembly pathway. Collectively, our results suggest that 40S assembly factors regulate the timely incorporation of ribosomal proteins by delaying specific folding steps in the 3’ major domain of the 20S pre-ribosomal RNA. Overall design: Three datasets of yeast ribosomal samples subjected to different chemical modifications; 1M7 dataset contains 8 different modified samples and 2 control samples; NAI dataset contains 3 different modified samples and 2 control samples; DMS dataset contains 1 modified sample and 1 control sample. Each sample consists of at least two replicates.

Description
Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) at SRA-INRA, France were used to profile abdominal adipose gene expression at 7 wk of age. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. The HG and LG chickens are valuable as a model for biomedical and agricultural traits. Massively parallel RNA sequencing (RNA-Seq) was completed on an Illumina HiSeq 2000 System for transcription analysis of HG and LG abdominal fat. Need information on data processing, statistical analysis, and differential expression. Keywords: abdominal fat, divergently selected chickens, growth, transcriptional profiling, differentially expressed genes Overall design: Abdominal fat mRNA profiles of high growth (HG genotype) or low growth (LG genotype) chickens at 7 weeks of age were generated by deep sequencing (on an Illumina HiSeq 2000 system).
Publication Title
Transcriptional analysis of abdominal fat in chickens divergently selected on bodyweight at two ages reveals novel mechanisms controlling adiposity: validating visceral adipose tissue as a dynamic endocrine and metabolic organ.

Description
We decribe the accessible chormatin landscape in RAS-induced (RIS) and NOTCH induced senescence (NIS) using ATAC-seq. By expressing active NOTCH (N1ICD) in the context of RIS, we find that N1ICD antagonises the formation of accessible regions in RIS. By performing co-cultures, we demonstrate that cells expressing a NOTCH1 ligand, JAGGED1, can antagonise the formation of RIS specific accessible regions. Overall design: mRNA profiles were IMR90 cells expressing ER:HRAS(G12V) and a control vector or MSCV miR30 shHMGA1 were generated. 6 biological replicates.
