What's a GeneRIF?

In myelinating co-cultures and in zebrafish, we find that the number of mature oligodendrocytes does not change as result of manipulating signaling through the ephrinA1-EphA4 system. However, in both systems, inhibition of EphA4 signaling leads to a higher number of myelin sheaths formed by each oligodendrocyte. In isolated oligodendrocyte cultures, activation of EphA4 reduced process extension.

The findings that ephrinA1-PE38/GM-CSF had a high efficacy in the activation of the dendritic cells would facilitate the development of in vivo dendritic-cell vaccines for the treatment of gliomas in rats

Data suggest that ephrinA1 ligands play a role in the pathophysiology of spinal cord injury.
Title: Expression profile and role of EphrinA1 ligand after spinal cord injury.
The Rac/PAK pathwayis involved in ephrinA1-mediated inhibition of cell spreading. In this way, ephrinA1, alone or in synergy with S1P, can participate in blood vessel destabilization, a prerequisite for angiogenesis.
Title: EphrinA1 inactivates integrin-mediated vascular smooth muscle cell spreading via the Rac/PAK pathway.
Ephrin A1 is expressed in adult thymic connective tissue trabeculae, most cortical epithelial cells, and both cortical and medullary thymocytes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
