( B ) Ranking the top 20 differentially expressed genes in ascending order of q-value. ( C ) Construct a protein-protein interaction network of differentially expressed genes through STRING online analysis database. ( D ) Based on the global PPI network ( C ), topological analysis using Cytoscape identified FGF4 as a hub gene. For clarity, the predicted interaction lines between FGF4 and key glycolytic genes (HIF-1α, HK2, LDHA, PGK1), as well as between HIF-1α and key glycolytic genes (HK2, LDHA, PGK1), were highlighted in red.

Figure Lengend Snippet: The KIBRA and p -PKMζ are activated in contralateral ACC neurons after CPTP. (A-F) Representative blots and columnar statistical charts show KIBRA, p -PKMζ, and PKMζ levels in contralateral ACC at different time points in Thoracotomy pain (A-C) or Thoracotomy no pain (D-F), * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001 vs Sham group; the data were analyzed by 1-way ANOVA followed by Tukey multiple comparisons test, n = 4∼7 rats in each group. (G-H) The photographs of the double immunofluorescence staining show that KIBRA and p -PKMζ are only colocalized with neuron markers (NeuN) but not with astrocyte marker (GFAP) and microglia marker (Iba1) in the Sham and CPTP groups. The white arrowheads indicate the co-immunostaining. Scale bar, 100 μm.
