Upon ligand binding, they dissociate from their cytoplasmic chaperone complexes and become nuclear, potentially undergoing homodimerization in the process. In each case, the past decade has seen a heightened interest in the development and
therapeutic potential of receptor modulators based on nonsteroid chemical frames, as these chemical entities are easier to synthesize and patent. Furthermore, the chemical diversity of these non-steroidal ligands is likely to increase both their tissue and gene selectivity.
