Targeting neddylation as a novel approach to lung cancer treatment (Review).

As a protein that resembles ubiquitin, neural precursor cell expressed developmentally downregulated 8 (NEDD8) takes part in neddylation, which modifies substrates in a manner similar to ubiquitination and alters the activity of target proteins. Neddylation may affect the activity of multiple signaling pathways, have a regulatory role in tumor formation, progression and metastasis, and influence the prognosis of cancer treatment. The present review summarizes the regulatory roles of NEDD8 in the MDM2‑p53, NF‑κB, PI3K/AKT/mTOR, hypoxia‑inducible factor, Hippo and receptor tyrosine kinase signaling pathways, as well as in the development and progression of lung cancer.
