Figure 6. STING and STAT1 mediate induction of type I and type II interferons following WEE1 inhibition.
(A and B) Knockdown of STAT1 (or siRNA control [siSCR]) by siRNA followed by treatment with 1 μM AZD1775 for 48 h in H82 cells.
(A) Western blots show expression of p-WEE1, total STAT1, and actin (loading control).
(B) Quantitative mRNA expression of IFN-α, IFN-β, and IFN-γ.
(C and D) Knockdown of STING (or siSCR) by siRNA followed by treatment with 1 μM AZD1775 for 48 h in H82 cells. The data shown represent the means ± SD of triplicate. p values were calculated by Student’s t test (*p < 0.05, **p < 0.01, ***p < 0.001).
(C) Western blots showing expression of p-WEE1, total STING, and actin (loading control).
(D) Quantitative mRNA expression of IFN-α, IFN-β, and IFN-γ. The data shown represent the means ± SD of triplicate. p values were calculated by Student’s t test (**p < 0.01, ***p < 0.001).
(E) Quantitative mRNA expression of IFN-α, IFN-β, IFN-γ, CXCL10, and CCL5 after treatment with 500 nM H151 or 1 μM C176 and 1 μM AZD1775 for 48 h in H526 cells. The data shown represent the means ± SD of triplicate. p values were calculated by Student’s t test (*p < 0.05, **p < 0.01, ***p < 0.001).
