Ku70 is essential for histone deacetylase inhibitor trichostatin A-induced apoptosis JIN MENG1,2*, FENG ZHANG1*, XU‑TAO ZHANG1, TAO ZHANG3, YU-HUA LI1, LEI FAN1, YANG SUN1, HE‑LONG ZHANG4 and QI‑BING MEI1 Ku70 Ku70 is a DNA repair subunit protein that binds to DNA double-strand break ends and helps repair DNA via the non-homologous end-joining (NHEJ) pathway (Mimori et al., 1986). From: International Review of Cell and Molecular Biology, 2019 In particular, the invention relates to small-molecules which function as inhibitors of Ku70/80 protein and the non-homologous end-joining (NHEJ) pathway, and their use as therapeutics for the 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.

Recently, NU7441 and KU-0060648, together with CRISPR promoted HDR mediated joining by 3–4 fold . The Ku heterodimer Ku70/80 is required for the NHEJ (non-homologous end-joining) DNA DSB repair pathway.

av FL Tarish · 2015 — After castration, the nuclear Ku70 levels were reduced in 12 patients (levels tumours, rendering these sensitive to PARP inhibitor treatments.

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. 2019-05-17 · The Ku70/80 heterodimer protein possesses a ring-shaped structure with high affinity for DSBs. Since 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. 2016-07-01 · Although the idea of developing inhibitors which target the Ku70/80 − DNA interaction is not novel, no such specific inhibitors have been published in the peer-reviewed literature to date .

We here describe an in silico, pocket-based drug discovery methodology utilizing the crystal structure of the Ku70/80 heterodimer. 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. In both established cell lines (Mia-PaCa-2 and PANC-1) and primary human pancreatic cancer cells, shRNA/siRNA-mediated knockdown of Ku70 significantly sensitized gemcitabine-induced cell death and proliferation inhibition. Surprisingly, specific inhibitors of the Ku70/80 heterodimer are currently not available.

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. To understand the mechanism by which the FA pathway counteracts NHEJ in genomic maintenance in HSPCs, we exposed BM LSK (Lin − Sca1 + c-kit +; Fig. 1a) cells from WT and Fanca −/− mice to DNA-PKcs inhibitor NU7026 or Ku70 knockdown in the presence of PARP inhibitor KU58948.

Authors: Jin Meng; Feng Zhang; Xu‑Tao Zhang; Tao Zhang; Yu‑Hua Li; Lei Fan; Yang Sun; He‑Long Zhang; Qi‑Bing Mei; View Affiliations Ku70 S155D vWA domain is su cient to inhibit Aurora B in an in vitro kinase assay. Finally, Aurora B inhibitor treatment of Ku70 S155D cells does not increase the prevalence of a DDR marker H2AX. This work suggests that Ku70 S155 phosphorylation inhibits Aurora B which in turn leads to DDR activation. 2014-04-01 · ERK1/2 pathway inhibition led to a decrease of Ku70 activity and an increase in Bax expression following cerebral ischemia in diabetic rats Immunohistochemistry demonstrated that some Ku70 positive cells and a large number of Bax positive cells were found in the hippocampal CA1 region from cerebral ischemia/reperfusion groups (NI/R, DCI, DCI + U0126 groups) at 1, 6, 24 and 48 hours after ischemia.

HDAC inhibitors induce Ku70 acetylation with repressed c-FLIP and activated Bax in cancer cells. Current studies indicate that Ku70 is a potential target of HDAC inhibitors and plays an important role during the induction of apoptosis.

Lastly, we demonstrate that Ku and Aurora B interact following ionizing radiation treatment and that Aurora B inhibition in response to DNA damage is dependent upon Ku70 S155 phosphorylation. Ku70 in TSA-induced apoptosis in the CRC cell lines HCT116 and HT29.
