Hebras, Jade. "Caractérisation moléculaire du petit ARN nucléolaire SNORD115 : un rôle dans la régulation de l'expression et de la fonction du récepteur à la sérotonine 5-HT2C ?" Thesis, Toulouse 3, 2020. http://www.theses.fr/2020TOU30209.
The nucleolus of mammalian cells contains hundreds of box C/D small nucleolar RNAs (SNORDs). Majority of them, guide sequence-specific 2'-O ribose methylations into ribosomal RNA (rRNA). Some of them facilitate RNA folding and cleavages of ribosomal RNA precursors or guide ribose methylations into spliceosomal small nuclear RNA U6. Recent studies propose that some SNORD could target other transcripts, possibly messenger RNA as suggested by the brain-specific SNORD115. SNORD115 is processed from tandemly repeated genes embedded in the imprinted SNURF-SNRPN domain. Defects in gene expression at this domain are causally linked to rare disease: the Prader-Willi Syndrome (PWS). Excitingly, SNORD115 displays an extensive region of complementary to a brain-specific mRNA encoding the serotonin receptor 5-HT2C. SNORD115 could influence 5-HT2C signaling by fine-tuning alternative splicing or A to I RNA editing of 5-HT2C pre-mRNA. Reduced 5-HT2C receptor activity could contribute to impaired emotional response and/or compulsive overeating that characterized the syndrome. My work was to test this hypothesis using a CRISPR/Cas9-mediated SNORD115 knockout mouse model. My results show that loss of SNORD115 expression, in vivo, does not alter the post-transcriptional regulation of 5-HT2C pre-mRNA processing. Others results from the team do not reveal any defects in anxio-depressive phenotypes and eating behaviour. Our study questions the regulatory roles of SNORD115 in brain functions and behavioural disturbance associated with PWS. On other hand, I have studied ribose methylation sites in rRNA from mouse tissues. This work was included in emerging field of the specialized ribosome hypothesis which suggests heterogeneity in ribosomes may impact activity of ribosomes. Our results show significant changes at few discrete set of sites, especially in rRNA from developing tissues. Also, rRNA from developing tissues is globally less methylated than rRNA from adult tissues. We focus on LSU-Gm4593 site because this position is specifically methylated only during development and hardly ever detected in adult tissues. Methylation at LSU-G4593 is guided by SNORD78. We propose that the expression levels of SNORD78 during development appeared to be regulated by alternative splicing of the host-gene and to correlate with the methylation level of its target site at LSU-G4593. We've used a human cell line (HEK293T) inactivated for the SNORD78 gene in order to understand the functionally role of the corresponding ribose methylation. Our work did not demonstrate any overt cellular phenotypes, even though translation fidelity and the precise function of LSU-Gm4593 remains unknown

Noncoding regulatory RNAs (ncRNAs) are in the focus of current research, since they participate in nearly all cellular processes. To get further insights into the functional and structural complexity of ncRNAs, we studied human ncRNAs belonging to two classes of ncRNAs, the nucleoplasmic spliceosomal snRNAs and the nucleolar and Cajal body-specific box C/D 2'-O-methylation guide RNAs. The U1 snRNP is an evolutionarily conserved, abundant nucleoplasmic snRNP that plays a central role in pre-mRNA splicing. According to a recently emerging view, besides its constitutive role in splicing, the U1 snRNP has important regulatory functions in different steps of pre-mRNA production. We demonstrated that a fraction of the human U1 snRNA specifically associates with the nuclear RNA-binding protein TAF15 that is known to interact with a subpopulation of TFIID and RNA polymerase II complexes. The U1-TAF15 snRNP is structurally and functionally distinct from the well-characterized U1 spliceosomal snRNP and it tightly associates with chromatin. The function of U1-TAF15 snRNP remains unknown; it might contribute to the coupling of transcription and splicing. WDR79 (also called WRAP53) has been recently identified as an essential factor for targeting a subclass of box C/D and H/ACA modification guide RNAs, as well as telomerase H/ACA RNA, into the Cajal bodies. Accumulation of box C/D and H/ACA RNPs in Cajal bodies is essential for the biogenesis of functional spliceosomal snRNPs and telomere synthesis. Co-immunopurification of WDR79-associated human RNAs, followed by cDNA synthesis and deep sequencing identified a large number of novel Cajal body-specific RNAs. We are currently dissecting the cis-acting RNA element responsible for WDR79-binding and for targeting box C/D 2'-O-methylation guide RNPs into Cajal bodies. We have also identified a novel Cajal body-specific 2'-O-methylation guide RNA that is predicted to direct methylation of cytidine 34 at the Wobble position of tRNA-Met-CAT elongator. Interestingly, tRNA modification is a novel function for vertebrate box C/D scaRNPs
