Unicellular Caenorhabditis elegans embryo imaged at the cortex plane during 25 seconds with α-tubulin labelling of the microtubules. The more persistent bright spots correspond to the contacts of the astral microtubules at the cell periphery, generating forces that position the mitotic spindle during cell division.

The coordination of spindle-positioning forces during the asymmetric division of the C. elegans zygote is revealed by distinct microtubule dynamics at the cortex

Mitochondrial Aurora kinase A induces mitophagy by interacting with MAP1LC3 and Prohibitin 2

Giulia Bertolin, Marie-Clotilde Alves-Guerra, Agnès Burel, Claude Prigent, Roland Le Borgne and Marc Tramier

Life Science Alliance (DOI: 10.26508/lsa.202000806)

FRET by FLIM analyses detect the interaction between the multifunctional Ser/Thr kinase AURKA-GFP and the autophagy marker mCherry-MAP1LC3 at sites of autophagosome formation (dashed area). The interaction is abolished with the autophagy-impairing drug Xanthohumol.
