Genomic analyses reveal miR-137 broad impact on genes associated with malignant transformation and neuronal differentiation in glioblastoma cells

ABSTRACT: miR-137 plays critical roles in the nervous system and tumor development. An increase in its expression is required for neuronal differentiation while its reduction is implicated in gliomagenesis. To evaluate the potential of miR-137 in glioblastoma therapy, we conducted genome-wide target mapping in glioblastoma cells by measuring levels of associations between PABP and mRNAs in cells transfected with miR-137 mimics vs. controls via RIPSeq. Impact on mRNA levels was also measured by RNASeq. By combining the results of both experimental approaches, 1468 genes were determined to be negatively impacted by miR-137; among them, 595 (40%) contain miR-137 predicted sites. The most relevant targets include oncogenic proteins and players in neurogenesis like c-KIT, YBX1, AKT2, CDC42, CDK6 and TGF
