An integrated approach for experimental target identification of hypoxia-induced miR-210.

ABSTRACT: miR-210 is a key player of cell response to hypoxia, modulating cell survival, VEGF-driven endothelial cell migration, and the ability of endothelial cells to form capillary-like structures. A crucial step in understanding microRNA (miRNA) function is the identification of their targets. However, only few miR-210 targets have been identified to date. Here, we describe an integrated strategy for large-scale identification of new miR-210 targets by combining transcriptomics and proteomics with bioinformatic approaches. To experimentally validate candidate targets, the RNA-induced silencing complex (RISC) loaded with miR-210 was purified by immunoprecipitation along with its mRNA targets. The complex was significantly enriched in mRNAs of 31 candidate targets, such as BDNF, GPD1L, ISCU, NCAM,
