Par-complex-dependent cell polarity can be cell-autonomously conferred to non-polar Drosophila S2 cells, unveiling temporal patterns toward the cortical localization of Par-complex aggregates that include a meshwork containing unit segments.
In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.
The basic helix-loop-helix transcription factor, HES3, acts downstream of the PAX3-FOXO1 fusion oncogene to impair muscle differentiation and promote tumorigenesis in rhabdomyosarcoma, a childhood muscle cancer.
PAR-6 and PKC-3/aPKC are essential for postembryonic development of C. elegans and control the organization of non-centrosomal microtubule bundles in the epidermis, likely through recruitment of NOCA-1/Ninein.
Genetic and biochemical approaches identify a new component of the cellular signaling machinery driving migration of limb muscle precursor cells during mouse embryogenesis and reveal the underlying molecular mechanism.
