Apoptosis pathways and their therapeutic exploitation in pancreatic cancer

•  Introduction •  Pancreatic cancer •  Apoptosis pathways •  Exploiting apoptosis pathways for pancreatic cancer therapy ‐  Exploiting the death receptor pathway for pancreatic cancer therapy ‐  Targeting ‘inhibitor of apoptosis proteins’ (IAPs) for pancreatic cancer therapy ‐  Exploiting the mitochondrial pathway fo cancer therapy•  ConclusionsResistance to apoptosis (programmed cell death) is a characteristic feature of human malignancies including pancreatic cancer, which is one of the leading causes of cancer deaths in the western world. Defects in this intrinsic cell death program can contribute to the multistep process of tumorigenesis, because too little cell death can disturb tissue homeostasis. Further, blockade of apoptosis pathways can cause treatment failure, because intact apoptosis signalling cascades largely mediate therapy‐induced cytotoxicity. The elucidation of apoptosis pathways in pancreatic carcinoma over the last decade has resulted in the identification of various molecular defects. How apoptosis pathways can be exploited for the treatment of pancreatic cancer will be discussed in this review.
