Figure 3: Effects of HL on protein expression of cyclin D1 (A) and cyclin E (B) in NSCLC cells. Cells were incubated with 200 μM HL for 48 hours. Then, cell cyclerelated proteins were detected by flow cytometry.*Significantly different (p<0.05) compared with the controls (Student’s t-test); data are the mean ± standard error (n=3) from three independent experiments.
