To inhibit ATM, the team used a molecule called KU-55933, identified by screening a library of potential compounds. And it did indeed suppress the replication

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.

For ATM inhibition experiment, ATM inhibitor KU55933 (Selleck, Houston, USA) was added to culture medium 2 h before addition of 25 μM RSV. Techniques: Western Blot, Expressing, Immunofluorescence, Staining, Laser-Scanning Microscopy, Incubation, Activation Assay, Flow Cytometry, Cytometry (A, B, and C) U2OS cells were pretreated with ATM inhibitor caffeine (A), wortmannin (B), or KU55933 (C) and then subjected to IR. Cells were harvested at the indicated time points . Article Snippet: The ATM inhibitor KU55933 was a gift from Kudos Pharmaceuticals. Techniques: Inhibition, De-Phosphorylation Assay Ataxia telangiectasia mutated (ATM) kinase is critical in sensing and repairing DNA double-stranded breaks (DSBs) such as those induced by temozolomide (TMZ). ATM deficiency increases TMZ sensitivity, which suggests that ATM inhibitors may be effective TMZ sensitizing agents.

Ku55933 atm inhibitor

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. KU55933 and caffeine abrogate ADR-induced early accumulation of E2F1 in the nucleolus.

Frontiers in cellular and infection microbiology, 9, 26. to the ATM inhibitor KU55933 and conversely that AT cells are sensitive to the PARP ATM and DNA-PK inhibition together give the same sensitivity to PARP Chemical Modulators for studying KU-55933 in the research area. KU-55933 is a potent and selective ATP-competitive inhibitor of ATM kinase (IC50 = 13 nM ATM Kinase Inhibitor (KU 55933) is a cell-permeable, potent, selective and ATP- competitive inhibitor of ATM (Ataxia telangiectasia mutated), a serine/threonine 5 Apr 2016 For example, KU55933, a specific inhibitor of the protein kinase ataxia- telangiectasia mutated (ATM), which is a key player in the signaling Phosphorylation of ATM on S1981 is inhibited by ATMi, consistent with the anticipated The KU55933 ATM inhibitor used was from Kudos Pharmaceuticals 23 Apr 2018 A number of selective inhibitors of ATM have been disclosed, the first of which, 2 ( KU-55933), was developed by KuDOS Pharmaceuticals (now KU-55933 is a specific ATM inhibitor, which has pro-apoptotic effect on tumor cells. In this study, we analyzed the synergistic effect of sorafenib and KU-55933 DNA repair inhibitors as radiosensitizers in human lung cells kinase (DNA-PK); KU55933 (10 μM), an inhibitor of ataxia-telangiectasia mutated kinase (ATM); KU55933 is a potent and selective ATP-competitive inhibitor of ATM, with an IC50 of 13 nmol/l and a Ki of 2.2 nmol/l. KU55933 has potential for use as a new (γ radiation / HeLa cells / ATM / ATR and DNA PK inhibitors / VE-821). J. VÁVROVÁ1, L. foci, KU55933 – a specific ATM inhibitor (2-morpholine-4-yl-.

H1299 cells were pretreated with ATM/ATR inhibitor caffeine (100 μM) or ATM-specific inhibitor KU55933 (250 nM) for 30 min followed by exposure to ADR (1 μM) for 6 h. KU55933, which suppresses ATM phosphorylation upon irradiation, could be applied in the radiotherapy of BCa patients with a DAB2IP gene defect. The established ATM inhibitor KU55933 was used as a positive control for ATM inhibition (24).

The roles of ATM in stimulating glucose uptake, glycolysis, motility, and proliferation of cancer cells were demonstrated by knocking-down ATM in these cells. KU-55933 treatment also inhibits tumor growth and metastasis in vivo in mouse mammary tumors through inhibition of GLUT1 translocation and vimentin expression.

ATP-competitive ATM inhibitors like KU-55933 might act in a similar way as kd ATM protein, which, upon prolonged exposure, may cause greater side effects in vivo than a loss of ATM protein expression would. Further studies will need to address this question, but the possibility should be considered for future clinical development of ATM inhibitors.

As an ATM inhibitor, KU-55933 significantly inhibited the increase of phospho-Akt at Ser473 in MDA-MB-453 and PC-3 cells treated with insulin and IGF-I following serum starvation. 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.

Pharmacological ATM inhibition by KU55933 in cisplatin-treated mice did not ameliorate, but instead exacerbated cisplatin-induced DNA damage and tubular injury, thereby increasing mortality.

For one, you could keep a healthy amount of cash on hand. OK, t Over the past couple years, the innovations coming out of the ATM industry have escalated.
