Relative quantification of stem cell markers (Prom1, Bmi1, CD15, Msi1, Msi2, Nanog, Nestin, Oct4 and Sox2) in control BORRU epidermal growth factor fibroblast growth factor (EGF-FGF) and radiation-survived BORRU after sensitization with KU-60019 [(EGF-FGF) + KU-60019 + 5 Gy]. BORRU under differentiative conditions [fetal calf serum (FCS)] were used as tissue control (DCtref).

Compared to KU-55933, KU-60019 is an improved more water-soluble inhibitor of the ATM kinase, while displaying similar target selectivity. KU-60019 has little activity against DNA-PKcs and ATR with IC50 values of 1.7 μM and >10 μM, respectively, as well as 229 other protein kinases such as PI3K, mTOR and mTOR/FKBP12. KU-60019 displays 3- to 10-fold more potency than KU-55933 at blocking radiation-induced phosphorylation of key ATM protein targets such as p53, γ-H2AX, and CHK2, in human glioma U87 and U1242 cells, as 1 μM of KU-60019 significantly induces >70% decrease of p53 (S15) phosphorylation to which extent ~10 μM of KU-55933 is required to achieve. KU-60019 effectively radiosensitizes human glioma cells with dose-enhancement ratio of 1.7 and 4.4 at 1 μM and 10 μM, respectively, and also radiosensitizes the normal fibroblasts but not the A-T fibroblasts. KU-60019 treatment (3 μM) blocks basal and insulin-induced AKT S473 phosphorylation by 70% and ~50%, respectively, and completely reduces radiation-induced AKT phosphorylation below the level of control. The effect of KU-60019 on AKT S473 phosphorylation can be seen in glioma cell lines and normal fibroblasts but not in A-T (h-TERT) cells, and can be significantly blocked by phosphatase inhibitor okadaic acid, suggesting a critical role of ATM kinase in regulating AKT phosphorylation via unknown phosphatase. Consistent with the inhibition of prosurvival AKT signaling, KU-60019 at 3 μM significantly inhibits migration and invasion of human glioma U87 cells by >70% and ~60%, respectively, as well as U1242 cells by >50% and ~60% respectively.

| In vivo | In orthotopic glioma U1242/luc-GFP xenograft models, the combination of KU-60019 and radiation significantly increases survival of mice than KU-60019 alone, radiation alone, or no treatment. In addition, p53-mutant gliomas is much more sensitive to KU-60019 radiosensitization than wild-type glioma. [2] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
