RNAi inhibits cellular growth in a time-dependent manner. The graph shows the cell count over 72 hr of no treatment (dashed line), treatment with 2 µM scrambled IL-10 dsRNA (dsScr, dotted line), and treatment with 2 µM RNAi IL-10 (RNAi, solid line). The x-axis corresponds to the number of days of treatment and the y-axis to the cell number. The graph is representative of triplicate IL-10 RNAi treatments.
