NOCICEPTRA: Gene and microRNA signatures and their trajectories characterizing human iPSC-derived nociceptor maturation


ABSTRACT: Nociceptors are specialized sensory neurons implicated in the reception and transduction of painful stimuli. Many pain disorders directly affect nociceptors but mechanistic insight into underlying pathway regulations is limited by the translational paresis from animal models to human pain disorders. Although transcriptomic data are available for rodent and post-mortem patient samples, no comprehensive transcriptomic data are currently available for human nociceptor development. Here, we performed paired long and small RNA sequencing for six timepoints during nociceptor differentiation from three different human iPSC cell lines. Complex bioinformatics analyses for differential gene expression, protein-protein interactions and mRNA targeting by microRNAs revealed five distinct differentiation stages with critical hub genes and microRNAs guiding nociceptor development. The online resource platform NOCICEPTRA was specifically developed to visualize respective mRNA and microRNA trajectories, as well as query disease specific pathways, thereby enabling researchers to determine susceptibility windows for nociceptor-associated disorders as well as possible new treatment targets.
