Antisense oligonucleotides as therapeutic agents

Progress in understanding the role of inhibitor of apoptosis proteins in molecular targeted therapy of esophageal cancer

The apoptosis and antiapoptotic signaling pathways play a critical role in the embryonic and lymphocyte development, immune system modulation, and tissue homeostasis, as well as carcinogenesis. As inhibitor of apoptosis proteins (IAPs) are highly expressed in several neoplasms and are closely related to carcinogenesis, cancer progression, radiochemotherapeutic resistance, and prognosis, therapies targeting IAPs have become a research hotspot for molecular targeted therapy of tumors. In recent years, many agents targeting IAPs which are being evaluated in clinical trials are showing promising prospect for neoplastic therapy. As such, the identification of key roles of IAPs in esophageal cancer has revealed their potential value as therapeutic targets. This report reviews the progress in understanding the role of IAPs in molecular targeted therapy of esophageal cancer.
