Figure 8. Model of the role of DUSP1 in promoting PDAC chemoresistance.

Figure 8

Gemcitabine activates JNK and p38 MAPK (p38) signaling, which mediates apoptotic cell death. Activated JNK and p38 MAPK then upregulate DUSP1 transcription, which negatively modulates JNK and p38 MAPK signaling activity and attenuate gemcitabine-induced cell death. Inhibiting DUSP1 in combination with gemcitabine treatment significantly enhances chemosensitivity of pancreatic cancer cells.
