Effect of CC-885 and CC-90009 on TP53 PTC readthrough. (A, B) HDQ-P1 cells were exposed to the indicated concentrations of CC-885 (A) or CC-90009 (B) for 48 h and p53 levels were determined. Vinculin was used as loading control. (C, D) HDQ-P1 cells were exposed to the indicated concentrations of CC-885 (C) or CC-90009 (D) in combination with 20 μg/ml G418 for 48 h and p53 levels were measured. Vinculin was used as loading control. (E, F) HDQ-P1 cells were exposed to the indicated concentrations of CC-885 (E) or CC-90009 (F) without or with 20 μg/ml G418 for 48 h and TP53 level was measured in triplicate samples (±S.D.). (G) HDQ-P1 cells were transiently transfected with transfection reagents only (Mock), FLAG-tagged eRF3a or eRF3a-G575N constructs and exposed to the indicated concentrations of CC-90009 in combination with 20 μg/ml G418 for 48 h and p53, eRF3a, eRF1 and UPF1 were measured. Vinculin and GAPDH were used as loading controls. * indicates statistically significant difference to untreated samples (P < 0.01).
