Opinion - Survivin, cancer networks and pathway-directed drug discovery

Although there is no shortage of potential targets for cancer therapeutics, we know of only a handful of molecules that are differentially expressed in cancer and intersect multiple pathways required for tumour maintenance. Survivin embodies these properties, and orchestrates integrated cellular networks that are essential for tumour cell proliferation and viability. Pursuing the nodal functions of survivin in cancer might lead to the development of global pathway inhibitors with unique therapeutic potential.
