TP53 and cancer: In addition, our bioinformatic analysis that has been discussed in details in Materials and Methods section of the current work has revealed other miRNA-34a-predicted target genes that could be involved in cancer-related biology, including genes for apoptosis [TP53INP (tumor protein p53 inducible nuclear protein), Tp53, and DFFA (DNA fragmentation factor subunit alpha)], cell proliferation (Ki67), and cell differentiation SOX2 (sex-determining region Y-box 2).
