The aim of this paper is to review the inhibitors of apoptosis proteins, a
recently discovered group of caspase inhibitors. We will briefly review the
relevance of apoptosis in prostate cancer and some of the control mechanis
ms, before describing the structure, function and regulation of these molec
ules. Lastly, we will consider the evidence for the role that IAPs may have
in cancer and the implications for prostate cancer in particular.
