细胞实验: Cell proliferation is assayed by measuring tritiated thymidine incorporation in vitro. Human coronary artery cells (hCa) are seeded into tissue culture flasks for expansion and applied to 96-well plates at desired density in complete media (5000 hCaSMC; 10 000 hCaEC). After 2 days, complete media is replaced with incomplete media to synchronize cells and induce G0 state. Two days later, incomplete media are removed and replaced with complete media (serum/growth factors) to induce G0 to G1 transition. Complete media also contain drug at desired concentrations to determine its effects on cell proliferation. On day 7, 3H-thymidine is added to cells to monitor DNA synthesis, and cells are harvested after overnight incorporation of radioactivity. After an incubation period of 72 h, 25 μL (1 μCi/well) of 3H-thymidine are added to each well. The cells are incubated at 37°C for 16-18 h to allow for incorporation of 3H-thymidine into newly synthesized DNA and the cells harvested onto 96-well plates containing bonded g
动物实验: Male Sprague-Dawley rats was administrate by intravenous or oral Zotarolimus(2.5 mg/kg)dissolved inethanol: propylene glycol: cremophor EL: D5W vehicle (20: 30: 2: 48, by volume).
