ELAVL1

Potential involvement and target identification of HuR/ELAVL1 in age-related ocular pathologies – Back to the origin

In the last decades, the post-transcriptional control of gene expression has become an area of intense investigation, delineating a complex scenario where several factors (e.g. RNA-binding proteins, coding and non-coding RNAs) orchestrate the fate of a given transcript. An intriguing hypothesis suggests that loss of RNA homeostasis is a central feature of many pathological states, including eye diseases. Since the elav (embryonic lethal, abnormal visual system) gene discovery in the Drosophila melanogaster, the mammalian ELAV-like family has confirmed its leading role in controlling the RNA metabolism (from splicing to translation) of genes with a key function in many physio-pathological contexts. Some relevant findings suggest the involvement of the HuR/ELAV-like1 member and its potential as a therapeutic target in age-related ocular pathologies.
