Cancer: Passenger deletions create cancer-specific Achilles heel
doi:10.1038/nrd3826
Cancer cells tend to shed tumour suppressor genes — and often delete neighbouring genes in the process. New research shows that genes deleted in cells that neighbour cancer cells create cancer cell-specific vulnerabilities that can be targeted by new anticancer strategies.

Structure-based drug design: Opening the door to an epigenetic target
doi:10.1038/nrd3827
A structure-guided approach has been used to identify the first specific small-molecule inhibitor of a jumonji histone demethylase.

Pyruvate kinase M2 activators promote tetramer formation and suppress tumorigenesis
doi:10.1038/nchembio.1060
A small-molecule activator specific for PKM2 binds to a site distinct from the endogenous activator fructose-1,6-bisphosphate, promoting tetramerization and constitutive activation of PKM2, to inhibit xenograft tumor growth in mice.

EPHA4 is a disease modifier of amyotrophic lateral sclerosis in animal models and in humans
doi:10.1038/nm.2901
Genetic or pharmacological inhibition of Epha4 is protective in rodent and zebrafish models of amyotrophic lateral sclerosis. In two patients, mutations in Epha4 are associated with longer survival, suggesting Epha4 may be targeted therapeutically.
