KU55933, which suppresses ATM phosphorylation upon irradiation, could be applied in the radiotherapy of BCa patients with a DAB2IP gene defect.

KU-55933 has been used as an ataxia-telangiectasia mutated (Atm) inhibitor. Packaging 5, 25 mg in glass bottle Biochem/physiol Actions KU-55933 is a very potent, specific inhibitor of Ataxia telangiectasia (A-T) mutated (ATM) kinase (IC 50 = 13 nM). KU-22933 treatment sensitizes cancer cells to ionizing radiation and cytotoxic drugs.

KU-55933 treatment also inhibits tumor growth and metastasis in vivo in mouse mammary tumors through inhibition of GLUT1 translocation and vimentin expression. Alterations in Cellular Energy Metabolism Associated with the Antiproliferative Effects of the ATM Inhibitor KU-55933 and with Metformin Mahvash Zakikhani1,2, Miguel Bazile2, Sina Hashemi2, Shiva ATM deficiency increases TMZ sensitivity, which suggests that ATM inhibitors may be effective TMZ sensitizing agents. In this study, the TMZ sensitizing effects of 2 ATM specific inhibitors were studied in established and xenograft-derived glioblastoma (GBM) lines that are inherently sensitive to TMZ and derivative TMZ-resistant lines. KU-55933是一种特异性的ATM激酶抑制剂，IC50值为13 nM[1]。ATM可以刺激Akt的Ser473磷酸化，介导胰岛素诱导的Akt充分激活。在血清饥饿后用胰岛素和IGF-I处理的MDA-MB-453和PC-3细胞中，作为ATM的抑制剂，KU-55933显著抑制Akt Ser473磷酸化的增加。 In this paper, we identified the nontoxic compound CP466722 as an inhibitor of ATM and offer a comparison to the established ATM inhibitor KU55933 ( 24). In response to IR, ATM initiates a signaling cascade and phosphorylates downstream targets (e.g., p53, Chk2, and SMC1) on characteristic sites which can be used as a measure of cellular ATM kinase activity ( 8 , 10 , 11 , 13 ).

Ku55933 atm inhibitor

KU-55933 ATM Inhibitor 10-1518-5mg Cell-permeable, potent, selective and ATP-competitive inhibitor of ATM (Ataxia telangiectasia mutated), a serine/threonine pr Here we tested if chemically inhibiting ATM in the absence of PARP-1 or inhibiting PARP-1 in the absence of ATM increased toxicity to each inhibitor in mammalian cells. We found that PARP-1 defective mouse embryonic fibroblast (MEF) cells (A11) were more sensitive to the ATM inhibitor KU55933 than A19 wild-type cells ( Figure 1A).

In the MTT assay, KU-55933 treatment suppressed cell proliferation by about 50% at concentration of 10 μM in MDA-MB-453 and PC-3 cells. KU-55933 (CAS 587871-26-9) is a potent, selective ATM kinase inhibitor, providing neuroprotection against H2O2-induced cell damage. Our study shows that a specific ATM inhibitor, KU-55933, blocks the phosphorylation of Akt induced by insulin and insulin-like growth factor I in cancer cells that exhibit abnormal Akt activity. Moreover, KU-55933 inhibits cancer cell proliferation by inducing G 1 cell cycle arrest. KU55933 is a selective and reversible inhibitor of the activity of ATM and thus can be used to transiently inhibit ATM kinase activity in cells (29). Previous work suggested that ATM has temporally distinct functions in cells exposed to IR. Here we demonstrate that the treatment of intracellular tachyzoites with the PI3K inhibitor caffeine or ATM kinase-inhibitor KU-55933 affects parasite replication rate in a dose-dependent manner. KU-55933 affects intracellular tachyzoite growth and induces G1-phase arrest.

Sometimes called antiangiogenic therapy, this treatment may prevent the growth of cancer by blocking the formation of new blood vessels. We are experiencing extremely high call volume related to COVID-19 vaccine interest. Please understand
