Figure Lengend Snippet: Activation of p53 by IMPDH inhibition is dependent on RS (A) Immunoblot of WaGa cells treated with MPA (1 μM) for indicated times. Representative of 3 independent experiments. (B) Immunoblot of WaGa cells treated with MPA (1 μM) and guanosine (10 μM) for 24 h. Representative of 3 independent experiments. (C) Immunoblot of WaGa cells treated for 24 h with MPA (1 μM) concurrent with inhibitors for ATR (250 nM; berzosertib), ATM (10 μM; KU55933), DNA-PK (10 μM; AZD7648) or with all three inhibitors combined (3x). Representative of 3 independent experiments. For panels A-C, the total KAP1 blot is a reblot of the pKAP1 blot, the total CHK1 blot is a reblot of pCHK1, and the total CHK2 blot is a reblot of pCHK2.
