Abstract:

Neddylation is overactivated in lung cancer, which promotes the development of lung cancer by activating its downstream CRL ubiquitin ligase and promoting the CRL tumor-suppressor protein substrate degradation. MLN4924, a small molecule inhibitor of Neddylation, plays an anti-lung cancer role by inducing cell cycle arrest, apoptosis and senescence. Furthermore, targeting the key enzymes of Neddylation and their substrates, Cullin family proteins, can inhibit the development of lung cancer.

Key words: Lung neoplasms, Molecular targeted therapy, Neddylation
