Latent membrane protein 1 ( LMP 1 ) is a primary oncogene encoded by the Epstein‐Barr virus, and various portions of LMP 1 are detected in nasopharyngeal carcinoma ( NPC ) tumor cells. LMP 1 has been extensively studied since the discovery of its transforming property in 1985. LMP 1 promotes cancer cell growth during NPC development and facilitates the interaction of cancer cells with surrounding stromal cells for invasion, angiogenesis, and immune modulation. LMP 1 is detected in 100% of pre‐invasive NPC tumors and in approximately 50% of advanced NPC tumors. Moreover, a small population of LMP 1 ‐expressing cells in advanced NPC tumor tissue is proposed to orchestrate NPC tumor tissue maintenance and development through cancer stem cells and progenitor cells. Recent studies suggest that LMP 1 activity shifts according to tumor development stage, but it still has a pivotal role during all stages of NPC development.
