TP53 and cancer: Table 4 summarizes lncRNAs thatregulate p53 in GI cancers. Through their regulation by p53 or their ability toregulate p53, lncRNAs clearly have important functions in the p53 network, and ourappreciation of these roles will continue to grow as we discover additional lncRNAsand elucidate their functions in cancer. Figure2 depicts lncRNAs’ roles in the p53 regulatory network.
