Oncogenesis and progression of hormone-dependent cancers

Oncogenesis and progression of hormone-dependent cancers



Estrogens and androgens stimulate the proliferation of epithelial cells of the breast and prostate, and contribute to the development of tumors. Breast and prostate cancers are the most common cancers in women and men, respectively, and are a major cause of death. Hormonal treatments based on anti-estrogens (e.g. Tamoxifen) and anti-androgens (e.g. flutamide, bicalutamide) are effective for some forms of these cancers, but also lead to resistance.
In order to study the molecular and cellular mechanisms underlying the initiation and progression of these cancers, we established mouse models reproducing the characteristics and kinetics of the human pathologies. This project aims to deconstruct the cellular complexity of their microenvironment, understand the molecular mechanisms of disease initiation and progression, as well as analyze the epigenetic signature and plasticity of tumor cells.
