RESEARCH HIGHLIGHT

FIRST PERSON

CELL SCIENTISTS TO WATCH

REVIEW

Summary: A review of recent findings that demonstrate autophagy-dependent cell death in various contexts and begin to elucidate molecular mechanisms that render autophagy a lethal process.

Summary: This Review discusses recent discoveries regarding the unusual segregation system of the single-unit mitochondrial genome of T. brucei.

SHORT REPORT

Summary: Nuclear functions of mammalian EGF receptors contribute to cancer. Here, we show that such functions are not conserved in the invertebrate Drosophila.

RESEARCH ARTICLES

Summary: The leukotriene B4–BLT1 axis regulates the polarized trafficking of the chemoattractant receptors FPR1 and C5aR1 from the trailing edge of polarized neutrophils, to drive persistent chemotaxis.

Summary: LRRC45 at distal appendages is required for early steps of axoneme extension by promoting transition zone establishment, Rab8a recruitment and satellite organisation.

Summary: In nitrogen-poor medium, inhibition of Cdk1 becomes essential for generating a proper wave of MBF-dependent transcription at G1/S, which prevents DNA replication stress.

Summary: Rab4A controls cargo segregation by forming a complex with rabenosyn-5, KIF3 and AP-3 on sorting endosomes to divert the cargo toward melanosomes.

Highlighted Article: Embryonic stem cells rely upon expression of a novel lipid-modified Gab1 adaptor protein to promote survival under nutrient-poor conditions.

Highlighted Article: Nuclei are highly branched throughout the heterogeneous population of healthy epidermal cells in the Xenopus tail fin periphery, and disruption of nuclear branching results in improper fin morphology.

Highlighted Article:Drosophila scarlet mutants show progressive loss of dopaminergic neurons, along with locomotor impairments, and Scarlet has a neuroprotective role in a Parkinson's disease model.
