TP53 and neoplasm: The expression level of MYC mRNA (2.01 ± 1.72 fold change) in tumor tissue samples was significantly higher than in non-neoplastic tissue (p = 0.0002), whereas the expression level of FBXW7 mRNA (0.53 ± 0.40 fold change) and TP53 mRNA (0.84 ± 0.55 fold change) in tumor tissue specimens was significantly lower than in non-neoplastic tissue (p < 0.0001 and p = 0.0011, respectively).
