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 . In part, this may be due to the relatively smooth surface of the central canal of the Ku70/80 ring, which is sparse in yielding suitable pockets for specific small molecule binding [10] . KU70 Inhibition Impairs Both Non-Homologous End Joining and Homologous Recombination DNA Damage Repair Through SHP-1 Induced Dephosphorylation of SIRT1 in T-Cell Acute Lymphoblastic Leukemia (T-ALL) [corrected] Because of this central position, the Ku70/80 dimer is a logical target for the disruption of the entire NHEJ pathway.

SIR1 deacetylates Ku70, causing it to sequester the proapoptotic factor Bax away from mito-chondria, thereby inhibiting stress-induced apoptotic cell death [4]. Upon treatment with the aC inhibitor hD tSa, acetylated Ku70 releases Bax, which then translocates to 2008-04-01 2013-12-05 The inhibition stemed from the presence of the DNA-end binding Ku70/Ku80 heterodimer which is the regulatory subunit of the DNA-dependent protein kinase (DNA-PK). Here, the origin of the repair inhibition was assessed by a new in vitro assay in which circular or linear plasmid DNA, damaged or undamaged, was quantitatively adsorbed on sensitized microplate wells. 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. 2014-04-11 Biomolecules 2020, 10, 1236 3 of 16 derivates. The Ku70 binding site in IN has been verified to be shielded by these inhibitors.

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.

Bax-Inhibiting Peptide, V5 - Calbiochem Bax-Inhibiting Peptide, V5, CAS 579492-81-2, is a cell-permeable pentapeptide based on the Ku70-Bax inhibiting domain. Acts as an effective Inhibitor for Bax-mediated apoptosis (~50-200 µM).

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. 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) Thus, prevention of the repair of DSBs produced by anticancer agents, including IR, through the inhibition of DNA-PK is an attractive approach to modulating therapy resistance. 2020-10-29 Inhibition of Ku70 acetylation by Set/taF-Iβ a previous report found that acetylation of Ku70 by CBP and PCaF at its C-terminal linker domain disrupts Bax interaction, thereby resulting in apoptotic cell death. to better understand the mechanisms by which Ku acetylation is regulated, we hypothesized that the INhat domain of Set/ta inhibits acetylation of Ku proF-Iβ - teins by both CBP and PCaF. 2015-09-29 Ku70 is essential for histone deacetylase inhibitor trichostatin A-induced apoptosis.

kidney cells. An increase in ubiquitinated Ku70 protein was observed in apoptotic cells, and proteasome inhibitors attenuated the decrease in Ku70 levels in apoptotic cells.
