Figure 3. USP16 suppresses the stemness properties of HCC cells.

Figure 3

(A) Representative images from sphere formation assays after the depletion of USP16 in Huh7 and PLC/PRF/5 cells are shown (bar, 100 μm). (B) The diameters of spheres of different groups were measured. The data represent the mean ± S.D, **p < 0.01, ***p < 0.001, determined by t-test. (C,D) Huh7 and PLC/PRF/5 cells with or without USP16 down-regulation were treated with 5-fluorouracil (C) and adriamycin (D). Cell viabilities were measured three days after drug treatment, and IC50 values were calculated and were tested using one-way ANOVA. The data represent the mean ± S.D. (E) The relative mRNA expression levels of the indicated stemness-related genes were analysed using real-time PCR in control and USP16-depleted Huh7 cells. Mean ± S.D are shown, *p < 0.05, **p < 0.01, ***p < 0.001, determined by t-test.
