The Ku protein plays a key role in multiple nuclear processes, e.g., DNA repair, chromosome maintenance, transcription regulation, and V(D)J recombination. Now the existence of relation between Ku protein functioning and processes that lead to transformation of normal cells into cancerous ones is determined. Ku plays an important role in the sensitivies to radiation and chemotherapy for cancer. Ku might be a new target for the treatment of lung cancer and theoretical foundation on study of proteomics of apoptotic gene in drug-resistance.
