Description
So far, the annotation of translation initiation sites (TISs) has been based mostly upon bioinformatics rather than experimental evidence. We adapted ribosomal footprinting to puromycin-treated cells to generate a transcriptome-wide map of TISs in a human monocytic cell line. A neural network was trained on the ribosomal footprints at previously annotated AUG translation initiation codons (TICs), and used for the ab initio prediction of TISs in 5062 transcripts with sufficient sequence coverage. Functional interpretation suggested 2994 novel upstream open reading frames (uORFs) in the 5´ UTR (924 AUG, 2070 near-cognate codons), 1406 uORFs overlapping with the coding sequence (116 AUG, 1290 near-cognate) and 546 N-terminal protein extensions (6 AUG, 540 near-cognate). The TIS detection method was validated on the basis of previously published alternative TISs and uORFs. On average, TICs in newly annotated TISs were significantly more conserved among primates than control codons, both for AUGs (p<10-10) and near-cognate codons (p=3.8×10-3). The derived transcriptome-wide map of novel candidate TISs will help to explain how human proteome diversity is influenced by alternative translation initiation and regulation. Overall design: Examination of translational initiation in human cell lines using ribosomal footprinting

Description
Epigenetic control of neural stem/progenitor cell fate is fundamental to achieve a fully brain architecture. Two intrinsic programs regulate neurogenesis, one by epigenetic-mediated gene transcription and another by cell cycle control. Whether and how these two are coordinated to determine temporally and spatially neural development remains unknown. Here we show that deletion of Trrap (Transcription translation associated protein), an essential cofactor for HAT (histone acetyltransferase), leads to severe brain atrophy due to a combination of cell death and a blockade of neuron production. Specifically, Trrap deletion forces differentiation of apical progenitor (AP) fate into basal progenitors (BP) and neurons thereby limiting the total neurogenic production. Despite Trrap’s general role in transcriptional regulation, a genome-wide transcriptome analysis of neuroprogenitors identified the cell cycle regulators that are specifically affected by Trrap deletion. Furthermore, E2F-dependent recruitment of HAT and transcription factors to the promoter of cell cycle regulators is impaired in Trrap-deleted neuroprogenitors. Consistent with these molecular changes, Trrap deletion lengthens particularly G1 and S phases in APs in vivo. Therefore, our study reveals an essential and a distinct function of Trrap-HAT in regulation of cell cycle progression that is required for proper determination of neuroprogenitor fate. Overall design: Determine gene transcriptions by comparing Trrap-deleted and wild type samples

Description
Background: Arsenite is one of the most toxic chemical substances known and is assumed to exert detrimental effects on viability even at lowest concentrations. By contrast and unlike higher concentrations, we here find that exposure to low-dose arsenite promotes growth of cultured mammalian cells. In the nematode C. elegans, low-dose arsenite promotes resistance against thermal and chemical stressors, and extends lifespan of this metazoan, whereas higher concentrations reduce longevity. While arsenite causes a transient increase in reactive oxygen species (ROS) levels in C. elegans, co-exposure to ROS scavengers prevents the lifespan-extending capabilities of arsenite, indicating that transiently increased ROS levels act as transducers of arsenite effects on lifespan, a process known as mitohormesis. The RNA-seq data comprises 2 biological replicates for worms exposed to 100nM Arsenite 48h after L4 and 2 biological replicates of the same age as controls Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de) Overall design: 4 samples: 2 mRNA profiles of C.elegans 48h after L4 exposed to Arsenite; 2 mRNA profiles of C.elegans 48h after L4 as controls (H20). The N2 wild type (var. Bristol) strain was used.
