In this study, we have observed that in contrast to the ATM selective inhibitor KU55933, ATM/ATR dual inhibitors such as caffeine and CGK733 can suppress cyclin D1 levels in cancer cell lines. A recent study suggests that mitogen-activated cyclin D1 expression is required for the induction of premature senescence . KU55933, which suppresses ATM phosphorylation upon irradiation, could be applied in the radiotherapy of BCa patients with a DAB2IP gene defect. Keywords:: DAB2IP , radiotresistance , bladder cancer , ATM , KU55933 2D chemical structure image of ab120637, KU-55933, competitive ATM kinase inhibitor. Functional Studies - KU-55933, competitive ATM kinase inhibitor (ab120637) HepG2 cells were incubated at 37°C for 60 minutes with vehicle control (0 µM) and different concentrations of KU-55933 (ab120637). KU-55933 is an ATM inhibitor by suppressing cell proliferation and induces apoptosis by blocking Akt in cancer cells with overactivated Akt. Availability: In stock Package KU-55933 is a specific inhibitor of ATM kinase with IC50 value of 13 nM [1]. ATM can stimulate Ser473 phosphorylation of Akt and mediate its full activation in response to insulin.

A ATM cellular inhibition by KU55933 was demonstrated in additional phosphorylation targets, including p53 Ser15, H2AX Ser139, NBS1 Ser343, Chk1 Ser345, and SMC1 Ser966. KU-55933 is a potent ATM inhibitor with an IC50 and K of 12.9 and 2.2 nM, respectively, and is highly selective for ATM as compared to DNA-PK, PI3K/PI4K, ATR and mTOR. For research use only. We do not sell to patients.

Nikolai Zhelev 2017-06-01 · At 20 μM, the ATM inhibitor increased the Dox-evoked LDH release (Fig. 1E, right panel). In summary, these data show that the ATM inhibitor is protective in the Dox model of cell damage at concentrations of 1 μM and 1–10 μM in UN- and RA-SH-SY5Y cells, respectively, without clear exacerbation of cell damage at its higher concentrations.

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.

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 ). ku-55933 atm kinase inhibitor. high purity, best price. trusted source for researchers and distributors. The inhibition of kinase ATR with its specific inhibitor VE-821 resulted in a more pronounced radiosensitizing effect in HL-60 cells as compared to the inhibition of kinase ATM with the inhibitor KU55933.

Ku55933 atm inhibitor

KU55933 is an ATP-competitive, thioanthrene-pyranone-based inhibitor of ATM kinase with an IC50 of 13 nM and Ki of 2.2 nM and >100-fold selectivity over PI3K related kinases. [1] KU55933 inhibits cell proliferation by inducing G1 cell cycle arrest by downregulation of cyclin D1 synthesis in MDA-MB-453 breast cancer cells and PC-3 prostate cancer cells.
