    ..Taken together, the data indicate that beta1,2-N-acetylglucosaminyltransferase I-dependent N-glycans are required for locomotory activity, life span, and brain development in Drosophila. ..

    ..Similar regulatory interactions between oppositely graded extracellular cues may be a common theme in guided cell and axon migrations. ..

    ..We propose that FSN-1 may negatively regulate insulin/IGF signalling, in part, through EGL-3-dependent insulin-like ligand processing. ..

    ..These results suggest that netrin-stimulated phosphorylation of RCM Tyr(568) recruits Shp2 to the cell membrane where it can potentially modify RCM phosphorylation and function. ..

    ..Thus, UNC-129 mediates expression of dorsoventral polarity information required for axon guidance and guided cell migrations in C. elegans. ..

    ..Our results show that C. elegans detects the absence of food by using a small neural circuit composed of three neuron types in which octopaminergic signalling is activated by the cessation of dopamine signalling. ..

    ..Our findings demonstrate that BRAP-2 is necessary for preventing an inappropriate response to elevated levels of reactive oxygen species by countering premature activation of BRC-1 and CKI-1. ..
