I3M in PBS was mixed with Matrigel containing heparin and recombinant mouse VEGF A. solution of I3M was prepared in dimethyl sulfoxide, stored at 208C, and as needed with cell culture medium for in vitro experiments or with PBS for animal experiments class II HDAC inhibitor then diluted. Recombinant human and mouse VEGF A was acquired from RayBiotech and eBioscience, respectively. Matrigel was from BD Biosciences. CYTOTOXICITY AND proliferation ASSAY The effects of I3M on cytotoxicity and cell proliferation were examined using the CellTiter 961 AQueous One Answer Cell Proliferation Assay and CytoTox 961 Low Radioactive Cytotoxicity Assay, respectively. MIGRATION ASSAY HUVECs were allowed to develop in to full confluence in 24 well plates precoated with 0. 10 percent gelatin and then incubated with 10 mg/ml mitomycin C at 378C in a 512-bit CO2 atmosphere for just two h to inactivate HUVECs. Monolayer inactivated HUVECs were damaged Urogenital pelvic malignancy by scratching with 0. 1 ml pipette tip. Fresh medium containing various concentrations of I3M was added. Images were taken under the AxioImager M1 microscope after 8 h incubation at 378C. PIPE FORMATION ASSAY Matrigel was thawed at 48C immediately, and each well of prechilled 24 well plates was incubated at 378C for 45 min and covered with 150 ml Matrigel. HUVECs were included in 1ml EGM and incubated with the indicated amount of I3M at 378C in a humidified five full minutes CO2 atmosphere. After 16 h incubation, the medium was removed and rhodamine described phalloidin was added to stain F actin. Pictures of fluorescently labeled cells were obtained using a ThermoScientific Cellomics ArrayScan High Contents Screening Reader and analyzed by a computerized protocol that identified the tubes formed by the association and clustering of the endothelial cells. AORTIC RING ASSAY Aortic ring assay was done as previously described with some changes. 48 well plates were covered with 100ml of Matrigel at 48C and incubated at 378C, five hundred CO2 Adriamycin molecular weight for 30-min. Aortas separated from SD rats were cleaned of periadventitial fat and connective tissues, and cut in to 1 to 1. 5 mm long bands. After being washed with PBS, the aortas were covered with yet another 100 ml of Matrigel and placed on the Matrigelcovered wells. Artery rings were cultured in 1. 5 ml of EGM without serum for 24 h, and then a medium was replaced with 1. 5 ml of EGM with car or I3M. The medium was changed every 2 days using the exact formula as described above. After 7 days, the growth was measured by taking photographs with the AxioImager ZI inverted microscope with a 4 objective lens. IN VIVO MATRIGEL PLUG ASSAY All animal studies were authorized by the Institutional Animal Care and Use Committee of Hallym College. Organized Matrigel then was injected subcutaneously into the flanks of 6 week old C57BL/6 male mice. All treatment groups included five rats. After 7 days, mice were sacrificed and Matrigel plugs were removed and fixed in 4% paraformaldehyde.
