D Bernard’s team – P Bertolino’s group
Pituitary tumors (PiTs) are the second most common intracranial neoplasms in adults. With an incidence of 15/1000 case per year, these tumors represent a major health issue. Although these tumors are generally slow proliferating and benign, 45-55% of those invade nearby tissues preventing the possibility of complete surgical resection and imposing the use of complementary therapeutic strategies. Understanding the mechanisms that drive PiT transformation, slow growing characteristic and aggressive evolution is therefore important. The cellular and functional diversity and the complex evolution of pituitary adenomas make their clinical analysis and management difficult. The lack of knowledge about their evolution makes their classification and the customization of therapeutic strategies impossible. These features also complicate the development of predictive prognostic tools and targeted-personalized therapies.
Our group is integrated through the Hospices Civils de Lyon in the National Reference center HYPO Pituitary Reference network, it assembles a research team that brought together clinicians and fundamental researcher, who aim to:
- Identify and characterize new markers of pituitary tumors through genomic approaches
- Develop relevant cellular and preclinical human-derived models
- Study the contribution of candidate mechanisms such as cellular senescence in those tumors
