  1. ...maturation rather than a consequence of decay.The model is based on a detailed long-read sequencing–based molecular analysis of the polyadenylation, cleavage, and capping status of mRNA molecules produced from approximately two dozen endogenous C. elegans NMD-target genes. We expect that a similar model...
  2. ...exon, altering only the 3′ UTR sequence while leaving the protein-coding sequence unchanged. Because the 3′ UTR contains many essential regulatory elements—such as microRNA and RNA-binding protein (RBP) binding sites—variation in 3′ UTR length can modulate target mRNA function, stability...
  3. ...for mammalian genes. It remains unknown if the polyadenylation events occurring across a cleavage zone represent poly(A) site microheterogeneity or the utilization of separate alternative poly(A) sites. Both heterogeneous cleavage and alternative polyadenylation (APA) can generate mRNAs with different 3′ UTRs...
  4. ...for destabilization and translational inhibition (Chekulaeva and Filipowicz 2009). Our cell type–specific mRNA half-life measurements also allowed us to examine the decay of known miRNA targets. C. elegans genes encoding subunits of the vacuolar adenosine triphosphatase (V-ATPase) complex, which controls...
  5. ...: 10,461,689–10,461,701. TargetScan predicts a high context score percentile of 79.00, suggesting the site as a favorable target. By evaluating miRNA binding to the mRNA before and after the mutation, Mimosa predicts a classification of one, and TargetNet predicts a probability of ∼0.84 for both cases...
  6. ...studies as well as new therapeutic angles to target eukaryotic pathogens.Cleavage and polyadenylation (CPA) are key steps in eukaryotic mRNA maturation, specifying the 3′ end of the transcript and the addition of the poly(A) tail. Required for the proper expression of nearly all mRNAs, the site of pre-mRNA...
  7. ...), but our long RNA-seq mappings could also be consistent with TR transcription in C. elegans being a byproduct of mRNA transcription.View larger version: In this window In a new window Figure 6. Transcription from a tandem repeat in various tissue types. This shows an alignment of long RNA-seq reads...
  8. ...μg total RNA, using the ZYMO RNA Clean & Concentrator-5 kit (Zymo R1015). The rRNA-depleted RNA (5 μL) was then mixed with 1 μL 50 pmol Universal miRNA cloning linker (NEB S1315S; 5′ rAppCTGTAGGCACCATCAAT–NH2 3′) at 65°C for 5 min, and then ligated using T4 RNA Ligase 2, truncated KQ (NEB M0373S...
  9. ...; Srivastava et al. 2018). This molecular effect connects to various post-transcriptional regulations, including alteration of mRNA stability, the gain or loss of miRNA, and/or RNA-binding protein targets (Mayr 2017). By -wide calculation of the weighted 3′-UTR length of genes, we found that 3′ UTR lengthening...
  10. ...to identify PAs from scRNA-seq and spatial data, and highlights the role of alternative PAs in neuronal gene regulation.For ∼70% of human genes, differential polyadenylation alters the 3′ untranslated regions (3′ UTRs) that may regulate mRNA metabolism and protein expression (Derti et al. 2012; Tian...
