DP-imaging software controlled Them. For the model of breast cancer lung metastases naked Mice with 2 Dehydrogenase cancer × 106 MDA MB 231 cells were injected via a tail vein. The cells were suspended in 200 l of complete media. The Mice were randomized into two groups. The group re AZD1152 U injections of AZD1152 125 mg / kg / day ip on days 1 and 2 of a 7-day cycle for 4 cycles, beginning two days after the injection of tumor cells. Control aids Mice were again U ip injections of vehicle. The M were Mice get 10 weeks after tumor cell injection Tet and lungs were weighted and tchen on Tumorkn. Tumor specimens were fixed in formalin and paraffin included for histological analysis. The breast cancer cells to cell cycle analysis were covered in bo Your 100 mm tissue culture and you lie they set for 24 hours.
100 nM AZD1152 HQPA or vehicle alone were applied to each plate were harvested for the indicated times and cells by trypsinization. The cells were collected and in 70% ethanol for 1 h fixed by using an additional Tzliches rinsing in PBS pH 7.40 follows. Propidium Peptidase-4 iodide L Solution with RNase A was added to each sample and the samples analyzed with a FACScalibur flow cytometer. The cells analyzed for apoptosis were covered in bo Its 100 mm and must be set for 24 hours before the addition of AZD1152 HQPA. The cells were washed with PBS and treated with trypsin harvested at appropriate times. The cells were suspended in 0.5 ml of binding buffer and 5 l of annexin V-FITC exposed for 15 minutes at room temperature in the dark. The cells were again washed and the IP-L Solution with RNase A was applied immediately prior to analysis.
Colony-forming soft agar colony forming assay tests were in triplicate plates with agar base performed × DME/F12 completely one Requests reference requests getting molten agar medium with 0.5% DMSO is low and controlled Or 80 nM AZD1152 HQPA. Agar base was Hesperadin at 6 cm bo Petri dishes and given to h Gardens. 5000 cells / plate added to top agar 0.35% with a controlled environment Or 80 nM AZD1152 HQPA. The plates were incubated at 37 with 5% CO2 for 26 days. Colonies of 100 cells gez Cooled with a dissecting microscope, and the results were r with the Student’s test. The colony forming assays were performed in triplicate by trypsinization and plated in breast cancer cells, Bo Your 6-cm tissue culture and 5000 cells / plate in v Lliger DME/F12 medium with either DMSO or 40 nM AZD1152 HQPA.
The plates were incubated for 12 days at 37 with 5% CO2 incubated for 12 days. The colonies were divided into three areas, which steered a cm2 / plate and the colonies between AZD1152 number per cm2 cells and cells gez Hlt The HQPAtreated were compared with students who test-St. Mobile fluorescence microscopy of breast cancer were cultured in chamber slides and treated with either DMSO or 20 nM AZD1152 HQPA for 48 hours. The chamber Objekttr hunters were with cold PBS 2 × L Flushed solution and fixed in 10% formalin. The cells were permeabilized with 0.2% Triton X-100, with DAPI found Rabbit and visualized with an Olympus IX81 fluorescence microscope.
