The results found some important genes, such as MYC, Cdh1, and Acaca in PPI network. MYC oncogenes, containing C-myc, N-myc, and L-myc, had been proved to be overexpressed in tumor cells and closely associated with tumorigenesis by regulating cell proliferation, apoptosis, and differentiation [34]. This evidence concerns the gene MYC and neoplasm.
