HipSci: the iPSC proteomic compendium


ABSTRACT: Human induced pluripotent stem cell (iPSC) technology holds great potential for therapeutic and research purposes, by providing improved models of disease and for studying mechanisms regulating differentiation. The Human Induced Pluripotent Stem Cell Initiative (HipSci) was established to generate large panel of high-quality human iPSC lines from both healthy donors and disease cohorts for the research community. Here we present a resource featuring a comprehensive proteomic analysis of >200 human iPSC lines obtained from >100 different donors. This dataset has identified in total >16,000 proteins expressed in iPSCs, with expression levels spanning 7 orders of magnitude. Our analysis of these lines has provided insight into mechanisms regulating primed pluripotency. All the proteomics data we have integrated into the Enclyclopedia of Proteome Dynamics where it can be browsed and analysed interactively. https://peptracker.com/epd/analytics

X chromosome inactivation (XCI) is a dosage compensation mechanism in female mammals whereby transcription from one X chromosome is repressed. Analysis of human induced pluripotent stem cells (iPSCs) derived from female donors identified that low levels of XIST RNA correlated strongly with erosion of XCI. Proteomic analysis, RNA sequencing (RNA-seq), and polysome profiling showed that XCI erosion resulted in amplified RNA and protein expression from X-linked genes, providing a proteomic characte  ...[more]
