Dystroglycan is a scaffold for extracellular axon guidance decisions
eLife, 2019 Axon guidance requires interactions between extracellular signaling molecules and transmembrane receptors, but how appropriate context-dependent decisions are coordinated outside the cell remains unclear.

Axon guidance proteins in neurological disorders [PDF]
, 2015 Many neurological disorders are characterised by structural changes in neuronal connections, ranging from presymptomatic synaptic changes to the loss or rewiring of entire axon bundles.

Mathematical guidance for axons
Trends in Neurosciences, 1998 Axon guidance by gradients plays an important role in wiring up the developing nervous system. Growth cones seem to sense a concentration difference across their spatial extent, and convert this into a signal to move up or down a gradient. In this article, a simple mathematical framework is developed to understand when and where gradient detection can ...

TAG-1 Multifunctionality Coordinates Neuronal Migration, Axon Guidance, and Fasciculation
Cell Reports, 2020 Summary: Neuronal migration, axon fasciculation, and axon guidance need to be closely coordinated for neural circuit assembly. Spinal motor neurons (MNs) face unique challenges during development because their cell bodies reside within the central ...

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Decreased expression of axon-guidance receptors in the anterior cingulate cortex in autism
Molecular Autism, 2011 Background Axon-guidance proteins play a crucial role in brain development. As the dysfunction of axon-guidance signaling is thought to underlie the microstructural abnormalities of the brain in people with autism, we examined the postmortem brains of ...

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
FEBS Open Bio, EarlyView.Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Electrical activity suppresses intrinsic growth competence in adult primary sensory neurons [PDF]
, 2009 The ability of neurons to regenerate in the adult mammalian central nervous system (CNS) is often poor, leading to persistent deficits after injury. Failure of axon regeneration in the CNS has been attributed to the presence of an extrinsic inhibitory ...

, 2016 Correct pathfinding and target recognition of a developing axon are exquisitely regulated processes that require multiple guidance factors. Among these factors, the second messengers, cAMP and cGMP, are known to be involved in establishing the guidance ...
