Theoretical analysis of the current literature reveals the structural assembly, transport regulation, and molecular functions of the BBSome, emphasizing its roles in cilium-related processes.
Live imaging and physical perturbations of spindles with unfocused poles reveal that mammalian spindle length emerges locally from kinetochore-fibers, but that global cues from focused spindle poles are needed to coordinate k-fibers across space and time and accurately segregate chromosomes.

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.
