CDKN2A and neoplasm: The output from TISIDB and TNMplot repositories revealed that seven tumors, namely COAD, KICH, KIRC, KIRP, LIHC, THCA, and UCEC, have demonstrated a significant positive correlation between CDKN2A levels and the tumor stage (Figure 1C), while HNSC, KIRC, LIHC, and UCEC showed a significant positive correlation between CDKN2A expression and the tumor grade (Figure 1D).
