RRNA cleavage ensures translational cessation in the mature sperm

ABSTRACT: We report how unique RNA seq profiles of ribosomal RNA (18S, 28S) present in sperm indicate specific cleavage sites. Additionally, these sequencing results reveal how overall character of RNA (GC content) can significantly affect overall distribution of mapped reads.

Intact ribosomal RNAs (rRNAs) comprise the majority of somatic transcripts, yet appear conspicuously absent in spermatozoa, perhaps reflecting cytoplasmic expulsion during spermatogenesis. To discern their fate, total RNA retained in mature spermatozoa from three fertile donors was characterized by Next Generation Sequencing. In all samples, >75% of total sequence reads aligned to rRNAs. The distribution of reads along the length of these transcripts exhibited a high degree of non-uniformity tha ...[more]

Project description:Cellular mRNAs are permanently associated to proteins in the form of ribonucleoprotein particles. In addition to the hnRNP and SR protein families, the double-stranded RNA-binding (DRB) proteins play important roles in mRNA synthesis, modification, activity and decay (Dreyfuss et al, 2002; Stutz & Izaurralde, 2003). Staufen is a DRB protein first described as a maternal factor involved in the localised translation of specific mRNAs during early development in the fly (Riechmann & Ephrussi, 2001). One of the human homologues, human Staufen1 (hStau1) forms ribonucleoprotein complexes known as RNA granules that contain proteins involved in translation regulation as well as cytoskeleton and motor proteins to allow the movement of the granule on the microtubules. Although many cellular mRNAs have been found associated to these RNA granules, the specificity of such binding and the mechanims of hStau1-RNA interaction are still unclear. Here we identified a protected sequence signature with high homology to human Alu family of short interspersed elements at the 3’-untranslated region of mRNAs specifically associated to hStau1 protein. Using a combination of affinity chromatography, RNAse-protection, deep-sequencing and bioinformatic analyses to compare the mRNAs differentially associated to hStau1 or a mutant protein unable to bind RNA we defined a collection of mRNAs specifically associated to wt hStau1. A common sequence signature consisting of two opposite-polarity Alu motifs was present in the hStau1-associated mRNAs and was shown to be sufficient for binding to hStau1 and hStau1-dependent stimulation of protein expression. Our results unravel how hStau1 identifies a wide spectrum of cellular target mRNAs to control their localisation, expression and fate. We suggest that mammalian Staufen1 protein has adapted to use the evolutionary recent Alu elements as recognition signals thereby increasing its possibilities for rapid identification to new mRNA targets. Staufen (wild type or mutant) associated RNAs were extracted from HEK293T cells and sequenced according the illumina mRNA-seq potocol (HiSeq2000 sequencer). A third sample, of RNA, associated to a wild type Staufen, was treated with RNase T1 so only RNA fragments directly attached to Staufen were purified and sequenced.

Project description:Purpose: In all vertebrates, the thymus is necessary and sufficient for production of classic adaptive T cells. The key components of the thymus are cortical and medullary thymic epithelial cells (cTECs and mTECs). Despite the capital role of TECs, our understanding of TEC biology is quite rudimentary. For instance, we ignore what might be the extent of divergence in the functional program of these two TECs populations. It also remains unclear why the number of TECs decreases rapidly with age, thereby leading to progressive thymic insufficiency. Methods: Systems level understanding of cell function begins with gene expression profiling, and the transcriptome is currently the only '-ome' that can be reliably tackled in its entirety in freshly harvested primary cells. In order to gain novel insights into TEC biology, we therefore decided to analyse the whole transcriptome of cTECs, mTECs and skin epithelial cells. We elected to analyse gene expression using RNA-seq rather microarrays because RNA-seq has higher sensitivity and dynamic range coupled to lower technical variations. Results: Our deep sequencing approach provides a unique perspective into the transcriptome of TECs. Consistent with their ability to express ectopic genes, we found that mTECs expressed more genes than other cell populations. Out of a total of 15,069 genes expressed in TECs, 25% were differentially expressed by at least 5-fold in cTECs vs. mTECs. Genes expressed at higher levels in cTECs than mTECs regulate numerous cell functions including cell differentiation, cell movement and microtubule dynamics. Almost all positive regulators of the cell cycle were overexpressed in skin ECs relative to TECs. Conclusions: Our RNA-seq data provide novel insights into the transcriptional landscape of TECs, highlight substantial divergences in the transcriptome of TEC subsets and suggest that cell cycle progression is differentially regulated in TECS and skinECs. We believe that our work will therefore represent a valuable resource and will be of great interest to readers working in biological sciences, particularly in the areas of immunology and systems biology. The mRNA profiles of cTEC, mTEC (from 14 thymi of 7-days old C57BL/6 mice) and skinEC (from the trunk and dorsum of seven newborn mice) were generated by RNA-sequencing using Illumina HiSeq2000.

Project description:CTCF (CCCTC-binding factor) is a highly conserved 11-zinc finger DNA binding protein with tens of thousands of binding sites genome-wide. CTCF acts as a multifunctional regulator of transcription, having been previously associated with activator, repressor, and insulator activity. These diverse regulatory functions are crucial for preimplantation development and are implicated in the regulation of numerous lineage-specific genes. Despite playing a critical role in developmental gene regulation, the mechanisms that underlie developmental changes in CTCF recruitment and function are poorly understood. Our previous work suggested that differences in CTCFM-bM-^@M-^Ys binding site sequence may affect the regulation of CTCF recruitment, as well as CTCFM-bM-^@M-^Ys regulatory function. To investigate these two possibilities directly during a developmental process, changes in genome-wide CTCF binding and gene expression were characterized during in vitro differentiation of mouse embryonic stem cells. CTCF binding sites were initially separated into three classes (named LowOc, MedOc, and HighOc) based on similarity to the consensus motif. The LowOc class, with lower-similarity to the consensus motif, is more likely to show changes in binding during differentiation. These more dynamically bound sites are enriched for motifs that confer a lower in vitro affinity for CTCF, suggesting a mechanism where sites with low-binding affinity are more amenable to developmental control. Additionally, by comparing changes in CTCF binding with changes in gene expression during differentiation, we show that LowOc and HighOc sites are associated with distinct regulatory functions. In sum, these results suggest that the regulatory control of CTCFM-bM-^@M-^Ys binding and function is dependent in part upon specific motifs within its DNA binding site. Mouse E14 ES cells were differentiated in vitro for 4.5 days using retinoic acid. RNA-Seq was performed from cells collected before and after differentiation.
