Abstract
To develop metastatic capability, tumor cells must evolve the capacity to survive in novel microenvironments. Recently, we showed that metastasis of neuroblastoma cells is enhanced by loss of caspase-8, an event that occurs frequently in this malignancy. In poorly metastatic cells, unligated integrins were found to trigger activation of caspase-8, providing a selective pressure to promote its attenuation and thereby increased survival in foreign adhesive environments. Our findings suggest one mechanism by which the organotropism of metastastic cancer cells can arise.
