Project description:Mutations in the RNA-binding protein, RBM10, result in a human syndromic form of cleft palate, termed TARP syndrome. A role for RBM10 in alternative splicing regulation has been previously demonstrated in human cell lines. To uncover the cellular functions of RBM10 in a cell line that is relevant to the phenotype observed in TARP syndrome, we used iCLIP to identify its endogenous RNA targets in a mouse embryonic mandibular cell line. We observed that RBM10 binds to pre-mRNAs with significant enrichment in intronic regions, in agreement with a role for this protein in pre-mRNA splicing. In addition to protein-coding transcripts, RBM10 also binds to a variety of cellular RNAs, including non-coding RNAs, such as spliceosomal small nuclear RNAs, U2 and U12. RNA-seq was used to investigate changes in gene expression and alternative splicing in RBM10 KO mouse mandibular cells and also in mouse ES cells. We uncovered a role for RBM10 in the regulation of alternative splicing of common transcripts in both cell lines but also identified cell-type specific events. Importantly, those pre-mRNAs that display changes in alternative splicing also contain RBM10 iCLIP tags, suggesting a direct role of RBM10 in these events. Finally, we show that depletion of RBM10 in mouse ES cells leads to proliferation defects and to gross alterations in their differentiation potential. These results demonstrate a role for RBM10 in the regulation of alternative splicing in two cell models of mouse early development and suggests that mutations in RBM10 could lead to splicing changes that affect normal palate development and cause human disease.

Project description:RBM10 is an RNA binding protein that was identified as a component of spliceosome complex, suggesting its potential role in splicing regulation. However, the direct experimental evidence for this function has been lacking. Here we characterized in vivo RBM10-RNA interactions and investigated the role of RBM10 in splicing regulation at the global level. We observed significant RBM10-RNA interactions in the vicinity of splice sites and identified hundreds of splicing changes following perturbation of cellular RBM10 abundance. A RNA splicing map integrating the binding pattern and splicing profiles revealed a significant correlation between RBM10-enhanced exon skipping events and its binding close to the splicing sites of both upstream and downstream introns. Furthermore, we demonstrated the splicing defects in a patient carrying a RBM10 mutation. Overall, our data provided insights into the mechanistic model of RBM10-mediated splicing regulation and established genomic resources for future studies on its function in different pathophysiological contexts. We sequenced the mRNA of HEK293 cells and LCL cells, and we determined the RBM10 binding sites using PARCLIP in HEK293 cells. In total we sequenced four mRNA-Seq libraries for KD and two for OE in HEK293 cells; for each of these libraries, we also sequenced one control library. We also sequenced the mRNA of one patient LCL and two normal LCL libraries. Two replicates of PARCLIP sequencing were perfomed.

Project description:RBM5, a regulator of alternative splicing of apoptotic genes, and its close homologues, RBM6 and RBM10, are RNA binding proteins frequently deleted or mutated in lung cancer. We report that RBM5/6 and RBM10 antagonistically regulate the proliferative capacity of cancer cells and display distinct positional effects in alternative splicing regulation. We identify the Notch pathway regulator NUMB as a key target of these factors in the control of cell proliferation. NUMB alternative splicing, which is frequently altered in lung cancer, can regulate colony and xenograft tumor formation and its modulation recapitulates or antagonizes the effects of RBM5, 6 and 10 in cell colony formation. RBM10 mutations identified in lung cancer cells disrupt NUMB splicing regulation to promote cell growth. Our results reveal a key genetic circuit in the control of cancer cell proliferation. CLIP-Seq analysis of RBM5, RBM6 and RBM10, with 2 biological replicates and one non-specific control for each protein.

Project description:RBM10 is an RNA-binding protein that plays an essential role in development and is frequently mutated in the context of human disease. RBM10 recognizes a diverse set of RNA motifs in introns and exons and regulates alternative splicing. However, the molecular mechanisms underlying this seemingly relaxed sequence specificity are not understood and functional studies have focused on 3’ intronic sites only. Here we dissect the RNA code recognized by RBM10 and relate it to the splicing regulatory function of this protein. We show that a two-domain RRM1-ZnF unit recognises a GGA-centred motif enriched in RBM10 exonic sites with high affinity and specificity and test that the interaction with these exonic sequences promotes exon skipping. Importantly, a second RRM domain (RRM2) of RBM10 recognises a C-rich sequence, which explains its known interaction with the intronic 3’ site of NUMB exon 9 contributing to regulation of the Notch pathway in cancer. Together, these findings explain RBM10’s broad RNA specificity and suggest that RBM10 functions as a splicing regulator using two RNA-binding units with different specificities to promote exon skipping.

RNA from 3 biological replicates of knockdowns of RBM5, 6 and 10 and a control set were used. Changes between the control and knockdowns were measured based on using a splice-junction array (Affymetrix HJAY).

Project description:Alternative splicing is a widespread but largely undercharacterized contributor to tumor heterogeneity, lineage plasticity, and clinical outcomes. To systematically define the pan-cancer landscape of alternative splicing, we leveraged a sensitive unsupervised strategy to iteratively discover and functionally describe the universe of coordinated and uncoordinated splicing events across 25 malignancies and >10,000 patients. This analysis uncovered more than 1,000 distinct splicing-based tumor subtypes, including ~200 with prognostic significance and captured three times the number of poor survival splicing events than conventional analyses. Among these tumor subtypes, we describe a recurrent, poor-prognosis lung adenocarcinoma subtype enriched for but not genetically dependent on RBM10 mutations, and a neuroendocrine-like breast cancer subtype exhibiting brain-specific microexon splicing. These subtypes recur across multiple tumor types, revealing conserved splicing programs that transcend tissue of origin. Comparison of splicing across malignancies revealed nine core pan-cancer modules linked to regulation of distinct RNA binding proteins and reciprocal regulation of lineage differentiation programs. These findings establish an orthogonal classification system based on splicing dysregulation, independent of canonical splicing factor mutations, with implications for prognostic biomarker discovery and therapeutic targeting.

Project description:Splicing factors have recently been shown to be involved in heterochromatin formation, but their role in controlling heterochromatin structure and function remains poorly understood. In this study, we identified a fission yeast homologue of human splicing factor RBM10, which has been linked to TARP syndrome. Overexpression of Rbm10 in fission yeast leads to strong global intron retention. Rbm10 also interacts with splicing factors in a pattern resembling that of human RBM10, suggesting that the function of Rbm10 as a splicing regulator is conserved. Surprisingly, our deep-sequencing data showed that deletion of Rbm10 caused only minor effect on genome-wide gene expression and splicing. However, the mutant displays severe heterochromatin defects. Further analyses confirmed that the heterochromatin defects in the mutant did not result from mis-splicing of heterochromatin factors. Our proteomic data revealed that Rbm10 associates with the histone deacetylase Clr6 complex and chromatin remodeling complexes known to be essential for heterochromatin silencing. We propose that Rbm10 serves as a platform to recruit Clr6 and chromatin remodelers to mediate heterochromatin formation. Our work together with previous findings further suggests that different splicing subunits may play distinct roles in heterochromatin regulation.
