Research activities

Research projects developed in PhRR concern organism adaptation to different physiological and pathophysiological conditions, with a particular focus on muscle tissue and its relationship with oxygen.

In this context, PhRR has developped 3 research axes:

  • Respiratory pathologies (COPD: Chronic Obstructive Pulmonary Disease, OSA : Obstructive Sleep Apnea),
  • Exercise training,
  • Hereditary and acquired myopathies (DMA: Disuse Muscle Atrophy, FSHD: Facio-Scapulo-Humeral Musclular Dystrophy).

Research projects are developed in the willingness of a translational approach and combine:

  • Clinical studies,
  • Experimentation in vivo (muscle deconditioning/reconditioning, continuous and intermittent hypoxia exposure, transgene electroporation, …),
  • Mechanistic studies in cell culture in vitro (macrophages, myoblastes, myotubes, isolated myofibres and satellite cells …)

Key research projects

  • Muscle-Brain communication in the context of obesity: which impact of exercise training?
  • Effect of intermittent hypoxia on respiratory and locomotor muscles in the context of OSA.
  • Effect of hypoxaemia on adipo/myokines in the context of COPD.
  • DUX4-HIF1 cross-talk in FSHD.
  • Adiponectin pathway: a therapeutical target to counteract muscle deconditioning ?
  • Muscle-targeting of antisense agents as therapy for myopathies.
  • Translational study of the relationship between muscular and respiratory functions in patients with FSHD: development of clinical and molecular criteria.
