YS110 induces G2/M cell cycle delay in NCI-H2452 cells. a Flowcytometry analysis using propidium iodide staining revealed that the percentage of G2/M phase cells increased while the percentage of G1 phase cells was reduced in NCI-H2452 cells treated 24 h with 2 μg/mL of YS110. A representative experiment is shown. b The average percentage of G2/M phase cells in NCI-H2452 cells treated 24 h with 2 μg/mL of YS110 was significantly increased (*p < 0.05)
