Figure 3

Proliferative inhibition of 4βHWE on H1299 cells. Cells were incubated with concentrations of 4βHWE (from 0, 1, 5, and 10 μg/mL) for 24 and 48 h. The proliferation inhibition was determined by Trypan blue assay. The data was mean ± SD, n = 3. The asterisks indicated the statistical significance between drug treatment for 24 h and 48 h at the same concentration according to the Student t test (P < 0.05* and 0.001**, respectively).
