RAD51 and non-small cell lung carcinoma: In terms of targeting DSB repair, it has been shown that DNA-PKcs inhibition (NU7026) in combination with X-ray irradiation or CIRT (50 keV/μm) in non-small cell lung cancer (H1299) cells was more effective compared with inhibiting the HR pathway (using the Rad51 inhibitor, B02) [58].
