Cell cycle changes after RNAi treatment.

<p>The proportion of HSC-3 cells in the S phase decreased from 50.8±1.6% to 36.6±0.4% after RNAi (<i>P</i> = 0.0018). The proportion of cells in the G0/G1 phase also increased from 37.7±4.9% to 54.1±0.5% after RNAi (<i>P</i> = 0.0018). Apoptosis was not detected.
