Slit1 and Slit2 cooperate to repel retinal ganglion cell axons in vivo, establishing a corridor that defines the site of optic chiasm formation. Double knockout mice (Slit1/Slit2) develop an ectopic anterior chiasm and axons project aberrantly, whereas single knockouts show few defects, demonstrating genetic redundancy and cooperative repulsion. |

Slit1 and Slit2 together constitute the chemorepellent activity of the septum that guides olfactory bulb axons to form the lateral olfactory tract (LOT). Septum from Slit1/Slit2 double-deficient mice progressively loses repulsive activity in a gene-dose-dependent manner, and LOT is completely disorganized in double mutants with axons entering the septum. |

Slit1 and Slit2 are not required for tangential migration of cortical interneurons from the basal telencephalon to the cortex; the repulsive activity in the basal telencephalon is maintained in Slit1/Slit2 double-deficient mice. However, loss of Slit1 and Slit2 disrupts positioning of cholinergic neurons in the basal magnocellular complex, indicating a role in cell positioning close to the midline. |

Slit-1 signaling through its receptor Robo-2 is required for dorsoventral zonal segregation of olfactory sensory neuron (OSN) axons in the olfactory bulb. In slit-1(-/-) mice, a subset of OSN axons that normally project to the dorsal OB mistarget to the ventral region. Robo-2 is expressed in OSNs in a high dorsomedial to low ventrolateral gradient, and Slit-1 is expressed in the ventral OB. |

Slit1, expressed on cranial neural crest cells, signals through Robo2 on ectodermal placode cells to mediate neural crest-placode cell interactions required for proper trigeminal ganglion assembly. RNAi depletion of Slit1 or Robo2, or blocking Robo2 function, disrupts ganglion formation mimicking neural crest ablation. |

Slit1-Robo2 signaling modulates N-cadherin protein expression on the placodal cell surface (post-translational regulation) to control placodal cell adhesion during trigeminal gangliogenesis. Blocking or augmenting Slit-Robo signaling alters N-cadherin surface levels without changing total N-cadherin mRNA or protein, and N-cadherin co-expression reverses Robo2 loss-of-function phenotypes. |

Sclerotome-derived Slit1 signals through Robo2 expressed on pioneer myoblasts downstream of MyoD and Myf5 to drive directional migration and differentiation of pioneer myoblasts, acting via RhoA to regulate cytoskeletal assembly. Loss of Robo2 or sclerotome Slit1 function perturbs directional migration and fiber formation without affecting myoblast specification. |

Slit1 stimulates cortical dendrite branching and axon elongation through endogenous Robo1/Robo2 receptors. The SH2/SH3 adaptor protein Nck2 (but not Nck1) is specifically required downstream of Robo activation for Slit1-induced changes in cortical neuron morphology; Nck1 and Nck2 both bind Robo via an atypical SH3-mediated mechanism. |

Slit1 regulates adult SVZ-derived neural precursor (NPC) migration in demyelinating conditions in a cell-autonomous manner. Slit1-deficient NPCs migrate faster and make more frequent directional changes than control NPCs (shown by time-lapse video-microscopy), and more SVZ-NPCs are recruited to demyelinating lesions in Slit1(-/-) mice, resulting in higher Olig2+ cell numbers within the lesion. |

SLIT1 antagonizes FSH-induced FOXO1 phosphorylation (but not LH-induced FOXO1 phosphorylation) in granulosa cells, and loss of Robo1 does not inhibit SLIT1's ability to antagonize AKT/FOXO1 signaling, indicating Robo1 is not the sole receptor mediating SLIT1 signaling in granulosa cells. SLIT1 and SLIT2 share common transcriptional targets and mechanisms, while SLIT3 does not replicate these effects. |

Injured neurons release ATP via increased vesicular nucleotide transporter (VNUT), and P2X7R inhibition (BBG) downregulates Slit1 in SGCs and upregulates VNUT in DRG neurons, indicating a neuron-to-SGC signal transduction mechanism. |

Slit1 is identified as a downstream transcriptional target of MET signaling in embryonic limb myogenic progenitors. Conditional Met knockout in the Pax3/somitic lineage reduces Slit1 expression in limb buds, and pharmacological MET inhibition in vitro confirms Slit1 as a MET-responsive gene. Slit1 knockdown in myoblasts leads to precocious myogenic differentiation, suggesting Slit1 represses premature myogenic commitment downstream of MET. |
