Fig. 3. Western blot analysis of apurinic/apyrimidinic endodeoxyribonuclease1 (APEX1) expression in biliary cancer cell lines after APEX1 knockdown. SNU-245, SNU-308, SNU-478, SNU-1079, and SNU-1196 cells were transfected with control or APEX1-targeted siRNAs. Forty-eight hours after transfection, whole cell lysates were probed with antibodies specific for APEX1 and α-tubulin.
