RESEARCH HIGHLIGHTS
STICKY WICKET
CELL SCIENTISTS TO WATCH
CELL SCIENCE AT A GLANCE
Multiple functions of phospholipase Cβ1 at a glance
Summary: Phospholipase Cβ1 relays Ca2+ signals in response to hormones and neurotransmitters, but recent studies reveal additional unexpected functions in protein translation and the cell cycle, which we describe here.
REVIEW
Advances on the roles of tenascin-C in cancer
Summary: A review of recent insights into the roles of the extracellular matrix molecule tenascin-C in tumorigenesis, tumor immunity and metastasis, and how this could be exploited for cancer disease management.
SHORT REPORT
AMPK promotes Arf6 activation in a kinase-independent manner upon glucose starvation
Highlighted Article: This study reveals a noncanonical role of AMP-activated kinase in which the α subunit C-terminal regulatory domain serves as a guanine-nucleotide-exchange factor for Arf6 during glucose deprivation.
RESEARCH ARTICLES
TORC1 and PKA activity towards ribosome biogenesis oscillates in synchrony with the budding yeast cell cycle
Highlighted Article: Single-cell time-lapse microscopy of budding yeast reveals oscillations in the activity of TORC1 and PKA signaling pathways under constant external conditions.
Mitotic spindle disassembly in human cells relies on CRIPT having hierarchical redox signals
Highlighted Article: The cysteine-rich protein CRIPT regulates spindle movement during mitosis and the expression of CRIPT with cysteine mutations completely blocks spindle disassembly in human cells.
Dictyostelium discoideum cells retain nutrients when the cells are about to outgrow their food source
Summary:Dictyostelium discoideum cells at high cell densities use extracellular polyphosphate to alter membrane properties and inhibit exocytosis of undigested or partially digested nutrients using a signal transduction pathway.
The atypical small GTPase RABL3 interacts with RAB11 to regulate early ciliogenesis in human cells
Summary: RABL3 cooperates with RAB11 to regulate ciliary vesicle formation during early ciliogenesis in human cells.
Conserved Pib2 regions have distinct roles in TORC1 regulation at the vacuole
Summary: Vacuolar localization of S. cerevisiae Pib2, a key TORC1 regulator that both inhibits and activates TORC1 activity via conserved regions, is key for recovery and cell growth following rapamycin exposure.
TOOLS AND RESOURCES
mNG-tagged fusion proteins and nanobodies to visualize tropomyosins in yeast and mammalian cells
Summary: Visualization of tropomyosin in living yeasts and mammalian cells.
Assessment of endocytic traffic and Ocrl function in the developing zebrafish neuroepithelium
Summary: Live-imaging assays to track endocytosis and monitor trafficking dynamics in the zebrafish neuroepithelium show involvement of the inositol phosphatase Ocrl, a protein linked to Lowe syndrome, in this process.
