(Submitter supplied) RNA decay is a crucial mechanism for regulating gene expression in response to environmental stresses. In bacteria, RNA-binding proteins (RBPs) are known to be involved in post-transcriptional regulation, but their global impact on RNA half-lives has not been extensively studied. To shed light on the role of the major RBPs ProQ and CspC/E in maintaining RNA stability, we performed RNA sequencing of Salmonella enterica over a time course following treatment with the transcription initiation inhibitor rifampicin (RIF-seq) in the presence and absence of these RBPs. more...

(Submitter supplied) FinO-domain proteins such as ProQ of the model pathogen Salmonella enterica have emerged as a new class of major RNA-binding proteins in bacteria. ProQ has been shown to target hundreds of transcripts including mRNAs from many virulence regions but its role, if any, in bacterial pathogenesis has not been studied. Here, using a Dual RNA-seq approach to profile ProQ-dependent gene expression changes as Salmonella infects human cells, we reveal dysregulation of bacterial motility, chemotaxis and virulence genes which is accompanied by altered mitogen-activated protein kinase signaling in the host. more...

(Submitter supplied) Since short reads from Illumina RNA-seq data are challenging to map to repetitive elements , we wanted to confirm the bulk RNA-seq findings using an orthogonal method, namely, using the long read technology of Pacific Biosciences (PacBio) full-length transcriptome sequencing. This dataset provided around 1.1 (WT) and 1.3 (RBM4 KO) million sequence reads of 2.6 kb average length mapping to the human genome.

(Submitter supplied) We hypothesized that RBM4 regulates HERVs by directly binding to their transcripts. To test this possibility, we performed photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation (PAR-CLIP). We performed four independent PAR-CLIP replicates of our own using HAP1 cells stably expressing a FLAG-tagged RBM4 (FLAG-RBM4) transgene under control of a doxycycline-inducible promoter. Following metabolic labeling with 4-thiouridine (4SU) and crosslinking with ultraviolet light (UV) of 312 nm wavelength, we isolated RNA covalently linked to FLAG-RBM4. more...

(Submitter supplied) Here, we implemented a computational pipeline to determine the correlation of expression between individual RBPs and ERVs from single-cell or bulk RNA sequencing data. One of our top candidates for an RBP negatively regulating ERV expression was RNA-Binding Motif Protein 4 (RBM4). This set of bulk RNA-sequencing experiments was performed to identify differentially expressed genes and repetitive elements, particularly HERVs, between independent Wild Type and RBM4 KO clones in the KBM-7 derived, near-haploid human cell line, HAP1

(Submitter supplied) The cold shock proteins belong to a family of RNA binding proteins presenting a highly conserved domain, called cold shock domain (CSD). They are involved in various cellular processes, including adaptation to low temperature, nutritional stress, cell growth and stationary phase. Here we investigate the role of CspC in C. crescentus stationary phase and the molecular mechanisms underlying gene regulation by this protein. more...

(Submitter supplied) ProQ has become a paradigm for the emerging family of FinO domain-containing RNA binding proteins. ProQ in Salmonella enterica has been shown to act as a global RNA binding protein as it interacts with a plethora of sRNAs and mRNAs. However, little was known about processes ProQ regulates in Salmonella which have precluded to functionally characterize ProQ in vivo. In here, we show that ProQ represses the utilization of succinate as carbon source. more...
