Nuclear receptors are modular transcription factors regulated by ligands, chromatin context, and expression level. Wang et al. 2026, in this issue of Stem Cell Reports show that Rora controls OKS-mediated reprogramming in a dose-dependent manner: moderate expression enhances iPSC formation, while high levels inhibit it, linking quantitative Rora control to immune and WNT signaling during cell fate conversion.
