In our study, MPT0G211 induced Ku70 acetylation. This led to the sequestration of Ku70 in the cytosol, which blocked its binding to double-strand breaks (Fig. 3c, d) and therefore impaired DOXO-induced DNA repair. Furthermore, acetyl-Ku70 promoted the dissociation of Ku-70 from BAX, thus promoting BAX-dependent cell apoptosis (Fig. 3e, f). Together, these findings demonstrate the multifaceted ability of MPT0G211 to potentiate the cytotoxic effects of DOXO.

Specifically, inhibition of HDAC activity leads to increased acetylation of Ku70, which disrupts its binding to Bax. In turn, Bax is released from Ku70, translocates to mitochondria, and triggers the release of cytochrome c and caspase-dependent apoptosis. Consequences of PARP‐1 inhibition for DSB repair in Ku70‐deficient cells To determine whether the increased chromatin‐binding affinity of PARP‐1 in response to NCS was relevant to DSB repair, we tested the inhibition of DSB repair (assessed by the level of γ‐H2AX dephosphorylation) in Ku70‐deficient MB‐231 cells pretreated with the PARP‐1 inhibitor DPQ. 2019-03-29 · Inhibition of NHEJ sensitizes Fanca −/− HSPCs to PARPi-induced cell death and genomic instability.

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. We identified a novel putative small molecule binding pocket and selected several potential inhibitors by computational screening.

However, the key regulator for synergism remains unknown. To our surprise, the expression of repair protein Ku70 is suppressed, while the high-glucose environment induces DNA oxidative damage in neurons. Here, we aim to investigate whether the inhibition of Ku70 by high-glucose conditions aggrandized bupivacaine-induced DNA damage.

Consequently, inhibition of the NHEJ pathway can modulate a radiation- or chemo-refractory disease presentation. The Ku70/80 heterodimer protein plays a pivotal role in the NHEJ process. It possesses a ring-shaped structure with high affinity for DSBs and serves as the first responder and central scaffold around which the rest of the repair complex is assembled.

The results Mimicking acetylation of K539 or K542 or treating cells with deacetylase inhibitors abolishes the ability of Ku70 to suppress Bax-mediated apoptosis.

Our results demonstrate a key role for Ku70. Specifically, inhibition of HDAC activity leads to increased acetylation of Ku70, which disrupts its binding to Bax. In turn, Bax is released from Ku70, translocates to mitochondria, and triggers the release of cytochrome c and caspase-dependent apoptosis. Ku70 is essential for histone deacetylase inhibitor trichostatin A-induced apoptosis.
