The cell adhesion receptor L1 was shown to signal in a variety of cancer cell types and in neuronal cells by different signaling pathways [42,43,44,45,46], and Mucin2 expression is regulated by several signaling pathways, including Ras, ERK, PKC, PI3K, and NF-κB signaling [47,48]. Here, NFKB1 is linked to cancer.
