The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.

Ribosome collisions along an mRNA are shown to recruit factors that prevent additional ribosomes from initiating translation on that mRNA, thereby providing time to resolve the collision.

Different RhoA and Rac1 dynamics at the cell front and rear are coordinated through periodic GTPase waves, which define the minimal autonomous biochemical machinery necessary and sufficient for cell migration.
Quantitative analyses of yeast P bodies reveals a small number of highly concentrated proteins and many weakly concentrated proteins, suggesting that the compartments are compositionally simpler than previously thought.

The presented primary epithelial acinus-based platform for studying interactions between normal and malignant cells will enable in depth analysis of the tumor initiation process on a molecular level.
