Aspirin suppresses SK-28 cellular proliferation. SK-28 cells (at 4 × 103 well−1) were seeded in 96-well plates and allowed to adhere overnight. Aspirin at the indicated concentrations was added for 1 day. Optical density representing viable cells was determined by the CellTiter 96 Aqueous Non-Radioactive Cell Proliferation Assay. Inhibition of proliferation is calculated as percentage of control cultures that were not treated with aspirin, mean±s.d. The inhibition was statistically significant at *P<0.05, **P<0.005, ***P<0.0005; n=3.
