Biography

Faculty Lecturer in Translational Neuroscience December 2012 - present

Dr Hautbergue was recruited to the Sheffield Institute for Translational Neuroscience in August 2012 to set up the laboratory of RNA Molecular Biology, which is aimed at understanding the cause of gene expression dysregulation in neurodegenerative diseases such as ALS/MND and SMA in order to develop novel strategies of neuro-protective therapies.

(i) Department of Neuroscience, SITraN, University of Sheffield, U.K. August – November 2012

Setting up the RNA biology laboratory and my research group in SITraN to apply my scientific skills in RNA biology research to the understanding of RNA processing dysregulation in ALS/MND.

(ii) Department of Molecular Biology and Biotechnology, University of Sheffield, U.K. March 2010 – July 2012

Research Interests

Our research focuses on identifying pathophysiological consequences of widespread RNA dysregulation in neurodegeneration in order to design, develop and test novel strategies of neuroprotective therapies.

Widespread dysregulation of the RNA metabolism has been recognised as a key pathophysiological component causing at least four neurodegenerative disorders: motor neurone disease (MND), also called Amyotrophic Lateral Sclerosis (ALS), spinal muscular atrophy (SMA), Huntington’s disease (HD) and spinocerebellar ataxias (SCAs). Widespread alteration of the transcriptome has also been reported in normal ageing of the brain and many neurodegenerative disorders are late progressive adult-onset diseases. Neurodegeneration in Parkinson’s disease (PD) or Alzheimer’s disease (AD) is also likely to exhibit and/or involve broad alteration of the RNA metabolism and of multiple biological processes.

Although some genetic causes of these often-fatal diseases are known, the multifactorial molecular mechanisms governing pathogenesis and progression are still poorly understood. Genome-wide studies from cell or animal models and human brains extensively described large alterations of transcriptomes at all levels of the RNA metabolism including mRNA/miRNA biogenesis and processing, axonal transport and translation of mRNA. Thousands of changes were reported in multiple cellular pathways with dysregulation reaching up to one third of the TDP-43 linked MND transcriptome. Since it is not feasible to investigate all individual changes, it is impossible to distinguish alterations that are causing neurodegeneration from those which are consequences of initial alterations – a bottleneck in the identification of gene expression-modifying therapies.

In fact, the functional outcomes of widespread RNA dysregulation in neurodegeneration and ageing remain uncharacterised at the protein levels, which are ultimately linked to neuron survival or death. Beyond our investigation of altered RNA/protein expression levels and the development of neuroprotective strategies, we also aim at answering challenging scientific questions concerning RNA dysregulation in neurodegeneration and ageing: Proportion and identities of abnormally processed RNA molecules that escape the safeguarding mechanisms of nuclear retention? Which abnormal proteins, sequences and numbers, get synthesised from incorrectly processed mRNAs? Roles of long intergenic non-coding (linc) RNAs that exhibit similar features to protein-coding genes?

Current Projects

Research in the laboratory focuses on the mechanisms of neurodegeneration and the identification of potential neuroprotective strategies in Motor Neurone Disease (MND) also called Amyotrophic Lateral Sclerosis (ALS), Spinal Muscular Atrophy (SMA), Parkinson’s disease (PD) and ageing of the brain. In particular, we aim to understand whether MND/ALS-neurodegeneration linked to C9ORF72, SOD1 and TDP-43 variants involve converging mechanisms of altered RNA metabolism and to investigate whether these relate to sporadic MND/ALS.

We use a combination of molecular biology, biochemistry, cellular biology, structural/functional and OMICS analysis in association with the development of novel experimental methodologies to uncover molecular mechanisms of gene expression that potentially cause and rescue the neurodegeneration process.

  • Generation of non-neuronal and neuron-like inducible cell models of neurodegeneration to characterise early changes in gene expression and spread of dysregulation over time, in combination with studies in animal models and in astrocytes and motor neurons differentiated from induced pluripotent stem cells (iPSCs) or induced neuronal progenitor cells (iNPCs) derived from patient fibroblasts. Whenever possible, we try validating our in vitro and in vivo results in human post mortem CNS tissues. We have access to the world largest collection of brain biosamples (Sheffield Brain Tissue Bank).
  • Identification of transcriptomes and translatomes. Since up-regulation of mRNA expression levels in transcriptome studies do not necessarily correlate with increased protein levels, the identification of all mRNA molecules undergoing translation into proteins (translatome) should better reflects protein expression changes and altered biological processes. Current methodologies aimed at identifying translatomes, such as polysome profiling, ribosome profiling and ribosome affinity purification, do not allow measuring the rates of actively translated mRNAs between biosamples, essentially generating qualitative results. The use of sucrose gradients also limits the high-throughput capacity of some of these complex techniques that are only performed by a few research groups around the world. We aim at developing a simpler technology that will allow purification and next generation sequencing of mRNA molecules actively translated into proteins.
  • Molecular mechanisms of TDP-43 proteinopathy, which involves the nuclear loss and cytoplasmic accumulation/ aggregation of TDP-43 and forms the hallmark of MND/ALS.
  • Identification of molecular mechanisms driving pathophysiological changes in C9ORF72-linked MND/ALS both at the levels of RNA-induced toxicity and non-ATG mediated RAN translation of toxic dipeptide repeat proteins.
  • Functional analysis of the master energy homeostasis co-transcriptional activator PGC-1alpha in ageing and neurodegeneration.
