Project description:Global transcriptome profiling hnRNP LL depleted 293T cells
| PRJNA729793 | ENA
Project description:We performed RNA-seq of 293T cells post depletion and SETD2 or hnRNP L to compare their global transcriptome profile. We also looked at the distribution of the histone mark H3K36me3 in wild type 293T to correlate it with the observed transcriptome changes upon SETD2 and hnRNP L depletion. We rescued SETD2 knock out 293T cells with SETD2 FL (Full Length), FLΔSRI (FLwoSRI) and FLΔSHI (FLwoSHI) and performed H3K36me3 ChIP-Seq.

Project description:Pre-mRNA splicing is regulated through combinatorial activity of RNA motifs including splice sites and splicing regulatory elements (SREs). Here, we show that the activity of a major class of mammalian SREs is highly sensitive to the strength of the adjacent 5' splice site (5'ss) sequence, and that this has important functional and evolutionary implications. Activity of G-run SREs was higher for intermediate strength 5'ss by ~4-fold relative to weak 5'ss, and by ~1.3-fold relative to strong 5'ss. The dependence on 5'ss strength was supported both by comparative genomics and by microarray and Illumina mRNA-Seq analyses of splicing changes following RNAi against the splicing factor heterogeneous nuclear ribonucleoprotein (hnRNP) H, which binds G-runs. This dependence implies that the responsiveness of exons to changes in hnRNP H levels is a bivariate function of both SRE abundance and 5'ss strength; this relationship may hold also for other splicing factors. This pattern of activity enables G-runs and hnRNP H to buffer the effects of 5'ss mutations, augmenting both the frequency of 5'ss polymorphism and the evolution of new splicing patterns.

Project description:Understanding how RNA binding proteins control the splicing code is fundamental to human biology and disease. Here we present a comprehensive study to elucidate how heterogeneous nuclear ribonucleoparticle (hnRNP) proteins, among the most abundant RNA binding proteins, coordinate to regulate alternative pre-mRNA splicing (AS) in human cells. Using splicing-sensitive microarrays, cross-linking and immunoprecipitation coupled with high-throughput sequencing, and cDNA sequencing, we find that more than half of all AS events are regulated by multiple hnRNP proteins, and that some combinations of hnRNP proteins exhibit significant synergy, whereas others act antagonistically. Our analyses reveal position-dependent RNA splicing maps, in vivo consensus binding sites, a surprising level of cross- and auto-regulation among hnRNP proteins, and the coordinated regulation by hnRNP proteins of dozens of other RNA binding proteins and genes associated with cancer. Our findings define an unprecedented degree of complexity and compensatory relationships among hnRNP proteins and their splicing targets that likely confer robustness to cells.

Project description:We used NEBNext Ultra Directional RNA Library Prep Kits to prepare RNA-seq libraries of total RNA from hnRNP A2/B1 and A1 depleted A549 cells. Pro-seq libraries were prepared from A549 cells using Illumina adapters hnRNP A2/B1 and A1 depleted A549 cells were generated by lentiviral infections of shRNA constructs. RNAs were isolated using Trizol.
