Texto completo da fonteCellular senescence represents one of the major fail-safe mechanisms that counteracts tumour development is defined as a state of irreversible cell cycle arrest as a consequence of stress response such as oncogenic challenge. Such cells undergoing Oncogene-induced Senescence (OIS) display profound alternation in their epigenome as their chromatin are largely decorated with prominent drivers of constitutive heterochromatin.Antisense RNA-mediated gene regulation has been attributed to play diverse roles in mediating various cellular processes and cell fates per-se. In yeast, histone variant H2A.Z cooperates with RNAi and heterochromatin machinery to regulate antisense transcription at convergent gene loci which can otherwise generate pervasive read-through transcripts owing to improper transcription termination. In mammals, whether such antisense transcripts (occurring by read-through transcription at convergent gene pairs) exist and how they are regulated remains unknown. Interestingly, the depletion of the human H2A.Z histone variant has been reported to induce cellular senescence. We thus wondered if the regulation of particular antisense transcripts at convergent gene pairs occurs in senescence, if their regulation by H2A.Z is conserved in mammals and, if so, if a functional significance can be attributed to these transcripts. To this end we took advantage of a well-established in-vitro OIS model. Briefly, we analysed genome wide strand specific RNA-seq analysis of cells undergoing Oncogene Induced Senescence. This led us to identify numerous convergent gene loci associated with accumulation of transcripts downstream of the designated transcription termination site in senescent cells, and extending to generate an antisense to the next gene located in the opposite strand of the convergent gene pair. We confirmed the RNA-seq data at two of such convergent loci. An RNAi based approach revealed that at least two of these transcripts are generated by transcriptional read-throughs. Hence we designated such pervasive transcripts as Senescence Triggered Antisense Read-through Transcripts (START). Importantly, we further found that the two STARTs for which we performed in depth studies repress the expression of the gene for which they are antisense. Finally, we demonstrate that the histone variant H2A.Z suppresses the accumulation of STARTs in proliferative cells. Since it also prevents senescence induction, this suggests that expression of START is important for cellular senescence. This has lead us to propose a model that human cells undergoing OIS are associated with loss of H2A.Z that leads to the wide spread accumulation of read-through transcripts owing to impaired termination control

Texto completo da fonteAlternative splicing of precursor RNA is a co-transcriptional process that affects the vast majority of human genes and contributes to protein diversity. Dysregulation of such process is implicated in various diseases, including tumorigenesis. However, the mechanisms regulating these processes were still to be characterized. In this study, we showed that perturbations of alternative splicing correlated with dysregulations of convergent transcription and DNA methylation. Convergent transcription could be generated between pairs of neighboring genes in opposite orientation, or between intragenic enhancers and their host gene. CENPO and ADCY3 was identified as a convergent transcription gene pair. We found, in a tumor progression model of breast cancer, that the splicing change of the ADCY3 variant exon22 correlated with an increase of its transcription that went against that of CENPO. By using targeted transcription repression system CRISPRi, we demonstrated that downregulating the transcription of CENPO could not reverse the alternative splicing alteration of ADCY3 in cancer cells (DCIS). An active intragenic enhancer was identified in the intron16 of CD44, at the downstream of its alternative exons. By using targeted transcription activation system CRISPRa, we showed that upregulating the transcription of CD44 could not alter the alternative splicing of CD44 in DCIS cells. These results suggest that convergent transcription modulation through changes of promoter activity does not alter the alternative splicing of ADCY3 and CD44 in DCIS cells. However, through replacing the intragenic enhancer by an inducible promoter, we found that intragenic transcription activation increased the inclusion level of several alternative exons of CD44 in HCT116 cells. This result suggested that local convergent transcription could have a direct impact on the alternative splicing of CD44. Furthermore, by using targeted DNA methylation system CRISPR/dCas9-DNMT3b, we showed that DNA methylation at variant exons could directly modify CD44 alternative splicing. This thesis work also explored the limitation and feasibility of studying alternative splicing with repurposed CRISPR systems

Texto completo da fonteDuring my PhD I studied how cells receive and integrate multiple signals from the extracellular milieu. I focused on Smad proteins and my project can be divided into two parts. My first project was centered on the transcription factor Mad (Smad1) and its requirement for the BMP and Wg pathways. Using a combination of genetic and biochemistry experiments, we showed that Mad is required for Wg signaling both in Tcf reporter gene assays and in vivo in Drosophila. We found that the choice for Mad to transduce Dpp or Wg signals is controlled by C-terminal phosphorylations so that Mad binds to Pangolin and participates in Wg target genes transcription only when not phosphorylated at its C-terminus. This results in a competition between Dpp and Wg controlled by the phosphorylation state of Mad. My second project was focused on the tumor suppressor Smad4. When I first joined the lab, I identified three new potential GSK3 phosphorylation sites in Smad4 primary sequence. I used a home-made phospho-specific antibody to demonstrate that FGF or EGF stimulation trigger Erk-mediated phosphorylation of Smad4 which primes subsequent GSK3 phosphorylations. These phosphorylations regulate a transcription activation domain located in Smad4 linker region and generate a Wnt-regulated phosphodegron recognized by the E3 ligase beta-TrCP. This mechanism provides a means of integrating distinct pathways which would otherwise remain insulated, allowing cells to sense FGF and Wnt inputs and adapt TGF-beta outcome to their context. It provides a molecular explanation of the long-standing mystery of the “competence modifier” effect of Wnt on Nodal signals discovered 20 years ago
