| | In Vivo Aurora A inhibitory Assay ( MDA-MB-468) |
| Description: | Specifically, MDA-MB-468 cells (American Type Culture Collection) were maintained in Dulbecco's modified Eagle's medium (DMEM) plus 10% fetus bovine serum (FBS) (Invitrogen, US) at 37° C., 5% CO2. The cells were plated in 6 cm dishes at a density of 2x105 cells/dish. Cells were then treated with the compounds (0-10 uM); DMSO was used as a negative control and 0.5 uM VX-680 (Tozasertib) (Selleck Chemical LLC) was used as a positive control. Cells were harvested after 2 h of treatment and processed for SDS-PAGE and western blotting as described previously (Gizatullin et al., "The Aurora kinase inhibitor VX-680 induces endoreduplication and apoptosis preferentially in cells with compromised p53-dependent postmitotic checkpoint function" Cancer Res. (2006) 66 (15):7668-77). After electro-transfer onto nitrocellulose membranes, the membranes were blocked at room temperature for 1 h with TBS containing 5% (w/v) milk and then washed with a mixture of TBS containing 0.2% Tween 20 (Sigma). The membranes were then gently shaken at 4° C. overnight with anti-phospho histone H3 (Ser 10) antibody (9701, Cell Signaling), and anti-GAPDH monoclonal antibody (E10086CF, Covance) diluted in TBS containing 5% BSA. The membranes were then incubated with HRP conjugated anti-rabbit or anti-mouse IgG antibody (Jackson ImmunoResearch Lab.) at room temperature for 1 h followed by washing with Tween 20-PBS. The membranes were washed again with PBS and developed with the ECL system (PerkinElmer) as described previously (Berndt et al., "The Akt activation inhibitor TCN-P inhibits Akt phosphorylation by binding to the PH domain of Akt and blocking its recruitment to the plasma membrane." Cell Death Differ. (2010) 17(11):1795-804). |
