miR-126-5p promotes retinal endothelial cell survival through SetD5 regulatio in neurons

MicroRNAs are key regulators of angiogenesis, as illustrated by the vascular defects observed in miR-126-deficient animals. While the miR-126 duplex gives rise to two mature microRNAs (miR-126-3p and -5p), these defects were attributed to the loss of miR-126-3p while the role of miR-126-5p during normal angiogenesis in vivo remains unknown. Here, we show that miR-126-5p is expressed in endothelial but also by retinal ganglion cells (RGC) of the...
