Abstract:
Chemo- and radio-therapeutic regimens frequently kill cancer cells by inducing apoptosis, a cell-death subroutine that involves the activation of a particular class of proteases called caspases. In a recent issue of Nature Medicine, Huang et al. (2011) show that caspase activation in dying tumor cells causes the release of soluble lipid messengers, notably prostaglandin E(2), that stimulate tumor cell proliferation. In this short review, we will discuss the clinical and therapeutic implications of these findings.

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
