CDKN1A and adenocarcinoma: It should be noted that CDKN1A was the target gene with the highest number of significant negative correlations (p < 0.05) in both adenocarcinoma (miRNA-512-5p, miRNA-512-3p, miRNA-520a-3p and miRNA-520h) and SCC (miRNA-515-3p, miRNA-519b-3p, miRNA-520a-3p and mir-372-3p).
