Project description:Precise post-transcriptional regulation of gene expression is essential for vertebrate lens development. Disruption of the gene encoding the RNA-binding protein CELF1 leads to early-onset cataract in mice. Here, using iCLIP-seq in lenses, we mapped transcriptome-wide CELF1 binding sites, revealing interactions with the 3′UTRs of key transcripts involved in lens development and pathology, including Pax6, Prox1, Jag1, Maf, and Gja8. Integration with transcriptomic data and luciferase reporter assays demonstrated that CELF1 binding represses its target mRNAs by destabilizing transcripts and/or inhibiting their translation. Consistently, Maf and Gja8 are upregulated in Celf1-cKO lenses. In Xenopus laevis, forced overexpression of maf disrupted lens structure and eye morphology, confirming the developmental relevance of CELF1-mediated repression. Our findings uncover a post-transcriptional network in which CELF1 safeguards lens morphogenesis by limiting the expression of critical genes at the mRNA level

Project description:The CUG-BP and ETR-3-like factor 1 (Celf1) RNA binding protein plays an important role in heart and muscle development, and is over-expressed in the disease myotonic dystrophy. Celf1 has known roles in regulation of RNA splicing, RNA stability, and protein translation. To identify transcriptome-wide targets of the Celf1 protein, we performed CLIP-seq against Celf1 using the 3B1 antibody, in myoblasts, heart tissue, and muscle tissue. RNA Bind-N-Seq was performed using recombinant CELF1 protein in the presence of competing amounts of recombinant MBNL1 protein.

Project description:The CUG-BP and ETR-3-like factor 1 (Celf1) RNA binding protein plays an important role in heart and muscle development, and is over-expressed in the disease myotonic dystrophy. Celf1 has known roles in regulation of RNA splicing, RNA stability, and protein translation. To identify transcriptome-wide targets of the Celf1 protein in heart, we performed RNA-Seq of polyA+ RNA from mice inducibly expressing Celf1 in the heart. Mice were engineered to express the reverse tetracycline trans-activator (rtTA) from a heart-specific alpha myosin heavy chain promoter, and an N-terminal Flag-tagged version of the LYLQ isoform of human Celf1 from a tet-inducible promoter. Mice were fed doxycycline to induce Celf1 expression in heart, and hearts were harvested from 3 mice each at 12 hour, 24 hour, 72 hour, and 7 day time points. To account for potential doxycycline-dependent effects, control mice were fed doxycycline for 72 hours but these mice did not contain the tet-inducible Celf1 cassette. In total, 15 hearts were analyzed by RNA-Seq.

Project description:The RNA binding protein Celf1 regulates alternative splicing in the nucleus and mRNA stability and translation in the cytoplasm. Celf1 is strongly down-regulated during mouse postnatal heart development. Its re-induction in adults induced severe heart failure and reversion to fetal splicing and gene expression patterns. However, the impact of Celf1 depletion on cardiac transcriptional and posttranscriptional dynamics in neonates has not been addressed. We found that homozygous Celf1 knock-out neonates exhibited cardiac dysfunction not observed in older homozygous animals, although homozygous mice are smaller than wild type littermates throughout development. RNA-sequencing of mRNA from homozygous neonatal hearts identified a network of cell cycle genes significantly up-regulated and down-regulation of ion transport and circadian genes. Cell cycle genes are enriched for Celf1 binding sites supporting a regulatory role in mRNA stability of these transcripts. We also identified a cardiac splicing network coordinated by Celf1 depletion. Target events contain multiple Celf1 binding sites and enrichment in GU-rich motifs. Identification of direct Celf1 targets will advance our knowledge in the mechanisms behind developmental networks regulated by Celf1 and diseases where Celf1 is mis-regulated.
