Importin-β1 functions as a chromatin sensor to position the contractile ring for cytokinesis

The paper shows importin-β1 senses Ran-GTP gradients to position the contractile ring during cytokinesis, with effects dependent on cell ploidy.

The nuclear localization of Ect2 is required for cytokinesis

This study shows that nuclear sequestration of Ect2 is required for cytokinesis, as its persistent presence at the midbody leads to cytokinesis failure due to sustained RhoA activation.

Multi-tissue patterning drives anterior morphogenesis of the C. elegans embryo

The paper studies how three tissue types coordinate during anterior lumen formation in C. elegans embryos using microscopy and software analysis.
