title: [Bioluminescent imaging: applications to cancerology and endocrinology].
abstract: Our laboratory has been using various bioluminescent imaging systems for more than 20 years to visualize and quantify bioluminescent and chemiluminescent reactions. This equipment allowed us to establish numerous cell lines expressing bioluminescent reporter genes to study the mechanism of action of nuclear receptors. Cells expressing the luciferase gene under the control of a constitutive promoter were used to follow in vivo proliferation of cancer cells. Intensities of in vitro and in vivo bioluminescent signals were compared and the conditions of bioluminescent reaction measurements were determined. These bioluminescent models are new tools for evaluating cancer treatment efficiencies and the role of hormone receptors in invasion. Cells expressing the luciferase gene under the control of hormones are used as in vivo biosensors for studying analog bioavailabilities and in vivo response kinetics. They are complementary models to in vitro models that have been developed in our laboratory for several years. In the future, targeting reporter gene (luciferase and GFP) expression to specific tissues should allow the detailed localisation of the action of nuclear receptor ligands.
