Comparative iTRAQ proteomics revealed proteins associated with lobed fin regeneration in Bichirs.

To our knowledge, this is the first proteomic research to investigate alterations in protein levels and affected pathways in bichirs' lobe-fin/limb regeneration. In addition, our study demonstrated a highly dynamic regulation during lobed fin regeneration in P. senegalus. These results not only provide a comprehensive dataset on differentially expressed proteins during the early stages of lobe-fin/limb regeneration but also advance our understanding of the molecular mechanisms underlying lobe-fin/limb regeneration.
