This Week in PNAS

In PNAS this week: analysis of proteolytic enzymes secreted by circulating tumor cells, phylogenetic study of Fv1 evolution, and more.

Investigators are studying samples from a group of 100 patients to try to lock down patterns in circulating tumor DNA that can be used to validate monitoring methods for the clinic.
