Description
We report that cellular ROS enzymatically generated in response to contact with lactobacilli in both mice and Drosophila has salutary effects against exogenous insults to the intestinal epithelium via the activation of Nrf2 responsive cytoprotective genes. Overall design: RNA was isolated from the colons of untreated, PBS, E. coli, and LGG innoculated germ free mice and RNA-seq performed to identify the gene expression in response to each condition

Description
In this work we have analyzed the transcriptomic profiles of E9 mouse embryos. We show that Hoxd1 and Haglr transcripts are absent after targeted deletion of the CpG: 114 island. Overall design: RNA-seq analysis of trunk from the anterior limit of the forelimb bud to the tailbud, aiming to exclude all extra-embryonic, head, cervical and heart tissues. Individuals 443 (wt) and 445 (Del(CpG114) homozygous), were siblings from the same dam, while biological replicates 456 (wt) and 455 (Del(CpG114) homozygous) were siblings from another dam.

Description
Hox genes are required during the morphogenesis of both vertebrate digits and external genitals.We investigated whether transcription in such distinct contexts involves a shared enhancer-containing landscape. We show that the same regulatory topology is used, yet with some tissue-specific enhancer-promoter interactions, suggesting the hijacking of a regulatory backbone from one context to the other. In addition, comparable organizations are observed at both HoxA and HoxD clusters, which separated through genome duplication in an ancestral invertebrate animal.We propose that this convergent regulatory evolution was triggered by the pre-existence of some chromatin architecture, thus facilitating the subsequent recruitment of the appropriate transcription factors. Such regulatory topologies may have both favored and constrained the evolution of pleiotropic developmental loci in vertebrates. Overall design: RNA-seq from mouse E12.5 digits cells and mouse E15.5 genital tubercle cells.

Description
We report here the transcriptome-wide distribution of yeast Rpb2, Sen1, Nrd1 and Nab3 binding sites. These data sets provide highresolution definition of non-poly(A) terminators, identify novel genes regulated by attenuation of nascent transcripts close to the promoter, and demonstrate the widespread occurrence of Nrd1-bound 3'-antisense transcripts on genes that are poorly expressed. In addition, we show that Sen1 does not cross-link to many expected ncRNAs but surprisingly binds to pre-mRNA transcripts suggesting a role in 3' end formation and/or termination. Overall design: Six samples by adaptation of PAR-ClIP procedure

Description
We report cell type specific Nova HITS-CLIP using BAC-transgenic lines expressing GFP-Nova under the motor neuron specific choline acetyltransferase (Chat) promoter. By comparing transcriptome wide Nova binding map in motor neurons and that in the whole spinal cord, we identified differential Nova binding sites in motor neurons, which correlate with motor neuron specific RNA processing. Overall design: 14 total samples were analyzed. For HITS-CLIP, 4 biological replicates were performed for each BAC-transgenic line, as well as the whole spinal cord. For RNA-seq, 2 biological repliates were performed on the whole spinal cord.

Description
Myelinating glia in the auditory system enclose auditory nerve fibers, providing an insulating effect that facilitates rapid transfer of auditory information from the ear to the brain. Here we show that noise exposure at the levels sufficient for inducing hearing loss cause a rapid cellular and molecular response on myelinating glia that precedes neuron degeneration. The response is characterized by inflammatory response, myelin dysmorphology and widespread changes in myelin-related gene expression. Another characteristic was change in expression of the quaking gene (QKI), which encodes a group of RNA binding proteins that are enriched in myelinating glia. Changes in QKI were accompanied by changes in numerous known and potential QKI target genes, including many genes associated with myelination. Our results implicate QKI as a critical early component in the noise response, influencing glia dysfunction that leads to auditory nerve demyelination and, ultimately, sensorineural hearing loss.
