    Daunorubicin induces p53-mediated apoptosis and GLI1 downregulation in HCT116 cells. (A) After AKT or ERK knockdown using siRNA, cell survival induced by daunorubicin was detected. (B) A phospho-kinase antibody array analysis showed that daunorubicin substantially increased p53 phosphorylation (S15, S46 and S392). The quantitation is depicted in the lower panel. (C) Western blot analysis for apoptosis-related marker proteins following treatment of daunorubicin (0.5 and 1 μ M) for 24 h. (D) Western blotting was used to measure the expression levels of c-PARP, p53, GLI1, p21 and Cyclin D1 in HCT116 and HCT116 p53 knockout cells. (E) Western blot analysis for PCAF and p300 following treatment of daunorubicin (0.5 and 1 μ M) for 24 h.

    Daunorubicin promotes GLI1 ubiquitination and proteasomal degradation. (A) HCT116 cells were treated with 2 μ M MG132 or 100 μ M leupeptin. (B) CHX chase assay showed that daunorubicin reduced the stability of GLI1 protein. Quantitation of GLI1 is also plotted. (C and D) Daunorubicin promoted the ubiquitination of GLI1 in HCT-116 cells. Immunoprecipitation using antibodies against each of the three E3 ligases revealed a major enhancement of β-TrCP-GLI1 interaction. (E) Results of daunorubicin (1 μ M) treatment for 24 h after β-TrCP knockdown using β-TrCP siRNA. Immunoprecipitation using GLI1 and β-TrCP antibody. The data are expressed as the mean of 3 independent experiments. ** P<0.005 and *** P<0.001. CHX, cycloheximide; siRNA, small interfering RNA.

(C) Treatment of daunorubicin (0, 0.5 and 1 μ M) for 24 h-induced apoptosis of HCT116 cells in a dose-dependent manner. Quantitation of cell death is plotted on the right. The graph was drawn by combining the B2 and B4 quadrants. (D) Treatment of daunorubicin (0, 0.5 and 1 μ M) for 24 h led to a dose-dependent increase in caspase3/7 activity. (E) HCT116 cells were pretreated with 25 μ M z-VAD-fmk for 30 min and then treated with daunorubicin (0, 0.5 and 1 μ M). Western blotting was used to measure the expression levels of c-PARP, caspase3, caspase9 and caspase8. (F) After GLI1 knockdown using GLI1 siRNA, cell survival induced by daunorubicin was detected. (G) After GLI1 knockdown using GLI1 siRNA, western blotting was used to measure the expression levels of c-PARP, caspase3, caspase9 and caspase8. The data are expressed as the mean of 3 independent experiments. **P<0.005, *** P<0.001 and **** P<0.0001. siRNA, small interfering RNA; c-PARP, cleaved poly (ADP-ribose) polymerase.

    Daunorubicin induces p53-mediated apoptosis and GLI1 downregulation in HCT116 cells. (A) After AKT or ERK knockdown using siRNA, cell survival induced by daunorubicin was detected. (B) A phospho-kinase antibody array analysis showed that daunorubicin substantially increased p53 phosphorylation (S15, S46 and S392). The quantitation is depicted in the lower panel. (C) Western blot analysis for apoptosis-related marker proteins following treatment of daunorubicin (0.5 and 1 μ M) for 24 h. (D) Western blotting was used to measure the expression levels of c-PARP, p53, GLI1, p21 and Cyclin D1 in HCT116 and HCT116 p53 knockout cells. (E) Western blot analysis for PCAF and p300 following treatment of daunorubicin (0.5 and 1 μ M) for 24 h. (F) Results of daunorubicin (0.5 and 1 μ M) treatment for 24 h after PCAF knockdown using PCAF siRNA. The data are expressed as the mean of 3 independent experiments. siRNA, small interfering RNA; K/O, knockout; c-PARP, cleaved poly (ADP-ribose) polymerase.

    Daunorubicin promotes GLI1 ubiquitination and proteasomal degradation. (A) HCT116 cells were treated with 2 μ M MG132 or 100 μ M leupeptin. (B) CHX chase assay showed that daunorubicin reduced the stability of GLI1 protein. Quantitation of GLI1 is also plotted. (C and D) Daunorubicin promoted the ubiquitination of GLI1 in HCT-116 cells. Immunoprecipitation using antibodies against each of the three E3 ligases revealed a major enhancement of β-TrCP-GLI1 interaction. (E) Results of daunorubicin (1 μ M) treatment for 24 h after β-TrCP knockdown using β-TrCP siRNA. Immunoprecipitation using GLI1 and β-TrCP antibody. The data are expressed as the mean of 3 independent experiments. ** P<0.005 and *** P<0.001. CHX, cycloheximide; siRNA, small interfering RNA.
