Uncovering a novel pathway for p16 silencing: Therapeutic implications for lung cancer

ABSTRACTA key step during onset of most cases of non-small cell lung cancer (NSCLC) is the loss of the tumor suppressor p16INK4a (best known as p16), commonly due to promoter hypermethylation. We recently reported a novel regulatory pathway involving E6-associated protein and cell division control protein 6, which provides a methylation-independent mechanism for p16 silencing in patients with a particularly aggressive form of NSCLC.
