High-throughput screening of 21 608 small molecules on prelamin A maturation. (a) Prelamin A and Hoechst immunostaining in HGPS MSCs treated with FTIs. (b) Primary screen cell-based assay for prelamin A localization. Dot plot representation of the effects of the 21 608 compounds on prelamin A maturation process and cell viability. (c) Dose-response experiments of the 11 prelamin A modulators identified. Each chart represents cell viability (in red) and percentage of prelamin A-positive nuclei (in blue). Each point represents the mean±S.D. of the percentage of eight replicates
