For example, 19 genes that act in Nerve growth factor (NGF)-Tropomyosin receptor Kinase A (TrkA) signalling were found to interact with neurotrophic receptor tyrosine kinase 1 (NTRK1) during neuroblastoma cell differentiation (FDR-corrected P-value = 1.59E-8) and that the same kinase is connected to transcriptional misregulation in cancer. Here, NGF is linked to cancer.
