We downloaded the co-expression data for netrin family members and transcription factors with binding sites located within the 1 kb upstream or downstream of the promoter, as well as chromatin remodeling factors in TCGA 32 cancers from ChIPBase v2.040 (20 NTN1 modifiers, 25 NTN3 modifiers, 19 NTN4 modifiers, 3 NTN5 modifiers, 18 NTNG1 modifiers, and 24 NTNG2 modifiers) (Fig. 6, Supplementary Data 7). The gene discussed is NTNG1; the disease is cancer.
