10、igation and play fighting than controlanimals3.PROTOCOLKinase Assay 1 The activity of caspase-3, -8 and -9 is assessed using the caspase-3, -8 and -9 colorimetric assay kits, respectively. Inbrief, 1106 cells in a 60-mm culture dish are incubated with 10 mM Valproic acid for 24 h. The cells are then

11、 washedin PBS and suspended in 5 volumes of lysis buffer provided with the kit. Protein concentrations are determined usingthe Bradford method. Supernatants containing 50 g total protein are used to determine caspase-3, -8 and -9activities. The supernatants are added to each well in 96-well microtit

12、er plates with DEVD-pNA, IETD-pNA or LEHD-pNA as caspase-3, -8 and -9 substrates and the plates are incubated at 37C for 1 h. The optical density of each wellis measured at 405 nm using a microplate reader. The activity of caspase-3, -8 and -9 is expressed in arbitraryabsorbance units.MCE has not in

After exposure to the designated doses ofValproic acid for the indicated times, MTT solution 20 mL: 2 mg/mL in phosphate-buffered

14、 saline (PBS) is added toeach well of the 96-well plates. The plates are additionally incubated for 3 h at 37C. Medium is withdrawn from theplates by pipetting and 200 mL DMSO is added to each well to solubilize the formazan crystals. The optical density ismeasured at 570 nm using a microplate reade

One week after the splenectomies, the mice receiv wholeAdministration 2 body irradiation with 137Cs at a dose of 4 Gy. At 48-72 h post-irradiat

16、ion, the mice are subcutaneously implantedwith Kasumi-1 cells (2107 cells/mouse with 0.15-0.2 mL) in the right axillary region. The mice are randomLy assignedto two groups, the Valproic acid (n=6) and control (n=6) groups. When the tumors are appr 200 mm3 in size at appr10 days post-implantation, 0.

17、2 mL Valproic acid (500 mg/kg body weight) or 0.2 mL saline is injected intraperitoneallyevery day. Valproic acid is dissolved in saline at a concentration of 25 mg/mL. The longest diameter (a) and theshortest diameter (b) of the tumor are measured every three days, and the tumor volume (TV) is calc

18、ulated accordingto the following formula: TV=1/2ab2. Following two weeks of injections, the mice are sacrificed by cervicaldislocation and the tumor masses are removed for the following experiments.MCE has not independently confirmed the accuracy of these methods.
