Table 4. Effects of S100A8 and S100A9 on doubling time and cell cycle of CNE-2 cells.

Group	Doubling time (h)
S100A8-RNAi	42.24±3.47*
S100A8-Overexpression	24.63±5.23*
S100A9-RNAi	56.17±5.34*
S100A9-Overexpression	29.23±5.51*
Control siRNA	36.27±5.52
Control overexpression	33.28±5.06
Normal control	32.35±4.73

*, compared with the normal control group, the difference was statistically significant (P<0.05).
