Analysis of the tumor microenvironment reveals that pancreatic tumors experience metabolic stress caused by immune cell degradation of the amino acid arginine, and that pancreatic cancers cope by synthesizing arginine to provide access this amino acid despite low tumor availability.

A comprehensive, quantitative, protein-protein interaction screen maps the network of interactions between human MIT domains and ESCRT-III C-terminal tails, and reveals MIT domain-containing protein cofactors for abscission and the 'No Cut' abscission checkpoint.
Zebrafish mutants and human endothelial cell experiments reveal that GIPC family endocytic adaptors bind to the Semaphorin receptor PLEXIND1, a critical regulator of vascular development, to negatively modulate its signaling.

A Topbp1 mutant mouse reveals a non-canonical role for the ATR-TOPBP1 signaling axis in meiosis, separating ATR signaling and meiotic sex chromosome inactivation from sex body formation.
Mice doubly deficient for Naa10 and Naa12 display embryonic lethality, with both enzymes compensating for each other with amino-terminal acetylation of proteins in mouse development.

TRIM37 prevents the formation of centriolar protein assemblies through an atypical de novo assembly pathway that would otherwise threaten genome integrity.

Isotope tracing into macromolecules enables functional analysis of metabolism in specific cell populations in tumors and provides insight into metabolic differences between cancer and stromal cells in their endogenous microenvironment.

In neurons of the Drosophila brain’s memory center, PKCδ relays a post-learning dopamine signal to mitochondria, boosting their metabolic activity and thereby unlocking long-term memory formation.
