Optogenetic activation of Rho GTPases provides spatiotemporal control over endothelial cell shape and enables control over endothelial barrier function by manipulating the cell-cell overlap with blue light.
A genetic approach in Caenorhabditis elegans shows that the cleaved and cytosolic form of the ubiquitin-like protein LGG-1/GABARAP is sufficient for both autophagy and embryonic development.
Specific glutamylation of some α-tubulin isotypes affects kinesin-1 localization and transport processes that depend on it, but their absence can speed up transport, possibly explaining why some large cells express α-tubulin isotypes that are not glutamylated.

Hypoxia does not increase glycolysis in proliferating primary cells and antagonizes the increase in glycolysis caused by activation of hypoxia-inducible factor in normoxia, in part, through activation of MYC signaling pathways.
The dietary vitamin riboflavin provides the chemical backbone to generate essential substrates that support liver glucose metabolism during low-nutrient conditions.
Type IV collagen plays a dual role in both structurally fastening tissues and signaling through the discoidin domain receptor 2 to synchronize an integrin adhesion that stabilizes tissue linkage.

Post-transcriptional regulation of Aurora Kinase A (AURKA) through alternative polyadenylation of its mRNA determines miRNA influence and is a feature of cell cycle-specific AURKA expression whose impairment leads to acquisition of cancer phenotypes.

Insight into the activity of β-heavy spectrin is provided by the discovery that it can compete with myosin for association with F-actin, which provides explanations for its influences on Hippo signaling and morphogenesis.
