  • Title: LOLA has the properties of a master regulator of axon-target interaction for SNb motor axons of Drosophila.
    Author: Madden K, Crowner D, Giniger E.
    Journal: Dev Biol; 1999 Sep 15; 213(2):301-13. PubMed ID: 10479449.
    Abstract:
    The proper pathfinding and target recognition of an axon requires the precisely choreographed expression of a multitude of guidance factors: instructive and permissive, positive and negative, and secreted and membrane bound. We show here that the transcription factor LOLA is required for pathfinding and targeting of the SNb motor nerve in Drosophila. We also show that lola is a dose-dependent regulator of SNb development: by varying the expression of one lola isoform we can progressively titrate the extent of interaction of SNb motor axons with their target muscles, from no interaction at all, through wild-type patterning, to apparent hyperinnervation. The phenotypes we observe from altered expression of LOLA suggest that this protein may help orchestrate the coordinated expression of the genes required for faithful SNb development.
