Abstract:
Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. In this thesis, the role of selected regulators, belonging to the class of small RNAs (sRNAs), is investigated. Streptococcus pyogenes is a pathogen responsible for a wide range of human diseases. Genome-wide screenings have indicated that S. pyogenes encodes numerous sRNAs, yet only a limited number h

Microorganisms are exposed to constantly changing environments, and consequently have evolved mechanisms to rapidly adapt their physiology upon stress imposition. These adaptive responses are coordinated through the rewiring of gene expression via complex networks that control the transcriptional program and the activity of post-transcriptional regulators. Although transcription factors primarily determine which genes are expressed, post-transcriptional regulation has a major role in fine-tuning the dynamics of gene expression. Post-transcriptional control is exerted by RNA-binding proteins an

Staphylococcus aureus is a highly problematic human pathogen due to its ability to cause devastating infections, paired with a capacity to withstand the action of a large fraction of available antibiotics.

Therefore, S. aureus has developed sophisticated regulatory networks to integrate a multitude of signals, enabling it to navigate the delicate balance between its pathogenic lifestyle and baselin

Abstract:
Chez les bactéries à Gram-négatif, l’imperméabilité de la membrane externe est un facteur majeur contribuant au développement de la résistance. Chez Escherichia coli, les porines OmpF et OmpC sont des protéines de la membrane externe qui forment des canaux pour la diffusion de petites molécules hydrophiles tels que les antibiotiques. L’expression des porines est soumise à une régulation fine, et des petits ARN non-codants (sRNAs, small RNAs) jouent un rôle important au niveau post-transcriptionnel. Dans ce cadre, et en utilisant E. coli comme bactérie modèle, les objectifs de mon travail de th

Abstract:
Memory storage and memory-related synaptic plasticity rely on precise spatiotemporal regulation of gene expression. To explore the role of small RNAs in memory-related synaptic plasticity we carried out massive parallel sequencing to profile the small RNAs of Aplysia. We identified 170 distinct 21-23 nt sized miRNAs, 13 of which were novel and specific to Aplysia. Nine miRNAs were brain-enriched, and several of these were rapidly down-regulated by transient exposure to serotonin, a modulatory neurotransmitter released during learning. Two abundant, and conserved brain-specific miRNAs, miR-124

Abstract:
Bacterial small non-coding RNAs (sRNAs) play fundamental roles in controlling and finetuning gene expression in a wide variety of cellular processes, including stress responses, environmental signaling and virulence in pathogens. Despite the identification of hundreds of sRNA candidates in diverse bacteria by genomics approaches, the mechanisms and regulatory capabilities of these posttranscriptional regulators have most intensively been studied in Gram-negative Gammaproteobacteria such as Escherichia coli and Salmonella. So far, almost nothing is known about sRNA-mediated regulation (riboregu
