NFKB1 and nasopharyngeal carcinoma: In summary, our data demonstrate that miR-125b is frequently upregulated in the NPC biopsies, and is an independent predictor for NPC patient survival; miR-125b regulates NPC cell proliferation and apoptosis by targeting A20/NF-κB signaling pathway; A20 inhibits NPC cell proliferation and induces NPC cell apoptosis both in vitro and growth in vivo.
