HnRNP Q and hnRNP A1 Regulate the Translation of Cofilin in Response to Transient Oxygen-Glucose Deprivation in Hippocampal Neurons.
Ontology highlight
ABSTRACT: Protein aggregates of cofilin and actin have been found in neurons under oxygen-glucose deprivation. However, the regulatory mechanism behind the expression of Cfl1 during oxygen-glucose deprivation remains unclear. Here, we found that heterogeneous nuclear ribonucleoproteins (hnRNP) Q and hnRNP A1 regulate the translation of Cfl1 mRNA, and formation of cofilin-actin aggregates. The interaction between hnRNP A1 and Cfl1 mRNA was interrupted by hnRNP Q under normal conditions, while the changes in the expression and localization of hnRNP Q and hnRNP A1 increased such interaction, as did the translation of Cfl1 mRNA under oxygen-glucose deprived conditions. These findings reveal a new translational regulatory mechanism of Cfl1 mRNA in hippocampal neurons under oxygen-glucose deprivation.
