Comparisons between regenerating and control samples. (A) Workflow for selecting control and regeneration groups for Fisher’s exact test. (B) Selected enriched gene ontology (GO) terms (FDR < 0.05) in regeneration or control groups for dorsal and ventral samples. Bars indicate the number of proteins in each group. (C) Network analysis of proteins expressed at higher levels in regenerating and dorsal samples. (D) Network analysis of proteins expressed at higher levels in regenerating and ventral samples. (C, D) Connections between nodes indicate protein-protein interaction. Only proteins that showed at least one interaction with another protein of the same group were displayed.
