Gene ontology (GO) analysis of the identified genes. a After performing Pearson correlation analysis at cutoffs of 0.98 < r < − 0.98 and p < 0.00001, the 41 selected genes were expanded to 221 genes, which were identified to be significantly correlated with one of the 41 genes. These genes were found to be involved in as many as 32 pathways; b Seven pathways were identified at the cutoff of FDR < 0.05, and NGF and Spp1 are likely to be the dominant drivers of all these pathways
