Abstract/OtherAbstract:
In many cell types translation can be regulated by an expression of the translation initiation factor. Eukaryotic translation initiation factor eIF4E, which binds to the 5' cap structure of mRNA, plays an important role in translation regulation and it has been suggested that it is implicated in increased protein synthesis promoted by growth factors. In this study the effects of nerve growth factor (NGF) infusion into the cerebrospinal fluid (CSF) on eIF4E expression and phosphorylation in mouse brain tissue have been investigated. We investigated NGF as it is one of the most important growth factors and it is an important factor in cerebral cortical development, stimulating neuronal precursor proliferation. eIF4E level is also increased in response to infusion of NGF into the CSF. The present study shows that eIF4E is phosphorylated in the brain tissues treated with NGF. It is concluded that NGF regulates protein synthesis in the nervous tissue by enhancing expression and phosphorylation of eIF4E.
