Figure S1 Retention and transmission of active transcription memory from progenitor to progeny cells via ligand-modulated transcription factors
Images demonstrate agonist-mediated generation of nuclear foci and their migration with the condensed chromosomes during all the stages of mitosis in a human cell line HEK-293T. HEK-293T cells were transiently transfected with GFP–AR and incubated in steroid-free medium for 24 h. Following receptor expression the cells were treated with either DMSO/ethanol (vehicle) for control cells or with DHT. After incubation period, live cells expressing GFP–AR were recorded by fluorescence microscopy. Left panels (−DHT) shows unliganded AR that does not associate with the condensed chromosomes during mitosis. Right panels (+DHT) shows DHT-activated AR that binds to the condensed chromosomes during all the stages of mitosis. The DNA stain Hoechst (blue) was used to visualize the corresponding nuclei/condensed chromosomes.
