KU-55933 has been used as an ataxia-telangiectasia mutated (Atm) inhibitor.[1][2]
Biochem/physiol Actions
KU-55933 is a very potent, specific inhibitor of Ataxia telangiectasia (A-T) mutated (ATM) kinase (IC50 = 13 nM). KU-22933 treatment sensitizes cancer cells to ionizing radiation and cytotoxic drugs. The compound KU-22933 blocks ATM-mediated phosphorylyation of p53, gH2AX, NBS1, and SMC1.

Recurrence of high-grade prostate cancer after radiotherapy is a significant clinical problem, resulting in increased morbidity and reduced patient survival. The molecular mechanisms of radiation resistance are being elucidated through the study of microRNA (miR) that negatively regulate gene expression.

SIRT6 has diverse roles in cells, and the role of SIRT6 in tumorigenesis is controversial. Considering the role of SIRT6 as an inducer of DNA damage repair, it might be involved in resistance to anti-cancer therapy. We evaluated the prognostic
A surveillance mechanism ensures repair of DNA lesions during zygotic reprogramming.
Peroxisomes perform beta-oxidation of branched and very-long chain fatty acids, which leads to the formation of reactive oxygen species (ROS) within the peroxisomal lumen. Peroxisomes are therefore prone to ROS-mediated damages. Here, using light to specifically and acutely induce ROS
The Tousled like kinase 1B (TLK1B) is critical for DNA repair and survival of cells. Upon DNA damage, Chk1 phosphorylates TLK1B at S457 leading to its transient inhibition. Once TLK1B regains its kinase activity it phosphorylates Rad9 at S328. In
