Genome expression and repair

Transcription, one of the key steps of gene expression in response to different stimuli of the organism like stress or hormones, requires a combination of factors. The deleterious action of physical or chemical agents that create lesions in the DNA disrupts the expression of genes. If these lesions are not removed by efficient repair systems they will be at the origin of mutations that can lead to cancer and aging. TFIIH, a multi-subunit complex that plays a pivotal role in both the transcription of genes and their repair. Mutations in some of the subunits of TFIIH are responsible for three genetic diseases (xeroderma pigmentosum (XP), trichotyodystrophy (TTD) and Cockayne syndrome (CS)), the phenotypes of which result from defects in both DNA repair and gene expression. For instance, TTD patients present brittle hairs and nails, that cannot account from a defect in DNA repair and that can be recapitulated in mouse TTD models. With the help of biochemical, genetic and cellular biology we study ageing and cancer predisposition in various cellular systems and animal models deficient in DNA repair and transcription processes.

• Current projects

  Our aim is to improve our understanding of the mechanisms that regulate the expression of protein coding genes at the transcriptional level and the maintenance of their integrity. Increasing amount of data indicates that expression and maintenance of the integrity of the genomic information are deeply linked. Defaults in each of these crucial cellular mechanisms are responsible of somatic and inherited diseases like cancers but are also involved in ageing.
  We would like to answer the following points:
  · How does TFIIH participate in the transactivation of specific genes?
  · How is transcription connected with DNA repair?
  · How mutations found in XP, CS or TTD affected the transcriptional program of a specific cell to stem for somatic diseases like cancer or hormonal dis-functions?
  · How efficiencies of DNA lesions removal play a role in the treatment against cancer?
  In a more applied aspect of our work we would like to use IPs cells from XP/TTD or CS patients to correct some of the phenotypes of the patients.
