Figure 1. Expression of DUSP4 is associated with DOX resistance in GC cells.

(A) Western blot of DUSP4 protein expression in GC cells. (B) CCK-8 assay of the viability of GC cells treated with different concentrations of DOX. (C) EDU assay of the proliferation of GC cells treated with their IC₅₀ of DOX. (D) Western blot of DUSP4 protein expression in GC cells cultured with or without their IC₅₀ of DOX. (^**P < 0.01).
