Cell proliferation was determined by a 3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay. 1 × 105 cells were seeded in each well of a 96-well plate (BD Falcon, Franklin, NJ) and allowed to adhere for 8 h. MTT solution was then added to each well at the final concentration of 0.5mg/mL and incubated for 4 hours at 37°C. After removing the culture medium, 150μL of dimethyl sulfoxide (DMSO), sunitinib and celecoxib were added respectively, and the optical density of each well was measured by spectrophotometer at 495 nm.
