The development of EBV-related neoplasms is influenced by a variety of genes and signaling pathways, which include activation of oncogenes such as Bcl-2 and MYC, as well as signaling pathways including NF-B, JNK, JAK/STAT, and PI3K/Akt, and deactivation of tumor suppressors such as p53, p27kip1, p21WAF1/CIP1, p16INK4A, p73, PRDM1, DICE1, and p27kip1(I, II). This evidence concerns the gene CDKN1B and neoplasm.
