The DNA-PK inhibitor, NU7441, could significantly inhibit DNA-PK and Ku70 expression, simultaneously further aggravating BP-induced apoptosis and DNA damage under high-glucose conditions. CONCLUSION: These data indicate that hyperglycaemia may enhance BP-induced neurotoxicity and DNA damage by inhibiting the DNA repair protein Ku70.

Surprisingly, specific inhibitors of the Ku70/80 heterodimer are currently not available. We here describe an in silico, pocket-based drug discovery methodology utilizing the crystal structure of the Ku70/80 heterodimer.

STL127705 also inhibits Ku-dependent activation of DNA-PKCS kinase (IC50, 2.5 μM). Because of this central position, the Ku70/80 dimer is a logical target for the disruption of the entire NHEJ pathway. Surprisingly, specific inhibitors of the Ku70/80 heterodimer are currently not available. We here describe an in silico, pocket-based drug discovery methodology utilizing the crystal structure of the Ku70/80 heterodimer.

The results of the present study have also demonstrated that TSA induced cell death in CRC cells through increasing the acetylation of Ku70, a Bax-binding protein, which therefore promoted Bax release and translocation from the cytoplasm into mitochondria in order to stimulate apoptosis. Since Ku70 S155D-expressing MEFs display cell cycle arrest and activation of a DNA damage response, a phenotype observed in Aurora B inhibitor-treated MEFs, we hypothesized that Ku70 S155D Ku70 in TSA-induced apoptosis in the CRC cell lines HCT116 and HT29.
