Inhibition of the proliferation of Meth A cells by KLH. Meth A sarcoma cells (5 × 10⁴ cells/well) were incubated with the indicated concentrations of KLH at 37°C in the 5% CO₂ incubator for 72 h. After removal of supernatants, the DNA against each cell was determined by MTT assay. The data are means ± SEM of three independent experiments. *P < 0.05, **P < 0.01, and ***P < 0.001, as compared with the control (Tukey's honest significant difference (HSD) test)
