Title: From Frog Pond to Clinic: Characterizing Elusive Disease-Causing Proteins and Cells
Abstract: A fundamental challenge in biomedicine is the existence of "missing" proteins—predicted by the genome but elusive in human tissue samples, potentially hiding key mechanisms of disease. To solve this, we require not just a catalog of molecules, but an organized "periodic table" of cell types, mapping their molecular identities across development to pinpoint where and when these proteins function. Leveraging the experimental power of the Xenopus frog, we have built the foundation for such a resource. We first performed a comprehensive proteomic analysis of 25 adult tissues, quantifying over 15,000+ proteins to define tissue-specific expression patterns and identify conserved and missing proteins. To complement this, we have constructed a comprehensive single-cell transcriptomic atlas spanning embryonic development and the adult organism, providing a systematic classification of cell types and states. This integrated map allows us to move from simply observing protein presence to understanding their cellular origin. Our future work will leverage this foundational atlas to characterize, at single-cell resolution, the phased emergence of the immune system in the developing frog. This focused effort will directly illuminate the cellular context of elusive immunoregulatory proteins, bridging a critical gap between early development and adult function. Referencing this resource we aim to identify tangible targets for clinical insight.
