方法 | Proliferation assays Cells were seeded in duplicate at 5,000-10,000 cells per well. The day after plating (day 1), NVP-AUY922 was added at 1 μM and 2-fold dilutions over 12 concentrations. Data were compared to untreated controls. Cells were counted on the day drug was added and five days later and these two counts were compared. Cells were harvested by trypsinization and counted immediately using a Coulter Z2 particle counter (Beckman Coulter Inc, Fullerton, CA). Percent growth inhibition, defined as 100 × (1 - [generations in treated wells/generations in untreated controls]) was determined. Experiments were performed in duplicate. Error bars represent standard error for each experiment. Non-linear curve fitting was performed by fitting curves to data points using the Proc NLIN function in SAS for Windows version 9.2 (SAS Institute, Inc., Cary, NC) using a basic four-parameter sigmoid model. IC50 (concentration needed to prevent 50% of cell population doublings) and IC100 (complete inhibition of proliferation) were the summary outcome measures interpolated from the resulting curves. |
