STAT3 and central nervous system cancer: The IPA analysis showed the involvement of the following canonical pathways: molecular mechanisms of cancer (FDR-corrected p-value = 7.45 × 10−10), glioma signalling (FDR-corrected p-value = 3.53 × 10−8), STAT3 signalling (FDR-corrected p-value = 1.63 × 10−7), glioblastoma invasiveness signalling (FDR-corrected p-value = 4.47 × 10−7), and synaptogenesis signalling pathway (FDR-corrected p-value = 2.29 × 10−6).
