Characterization of MicroRNAs Regulating FOXO Expression

Methods Mol Biol. 2019:1890:13-28. doi: 10.1007/978-1-4939-8900-3_2.

Abstract

MicroRNAs are critical post-transcriptional regulators of a majority of genes, of which the FOXO family of transcription factors is no exception. Here, we describe generalizable methods, including 3' UTR reporter assays and western blotting after microRNA manipulation, to test if a candidate miRNA (miR-182) directly targets a candidate (FOXO3) gene product. We also provide guidance on candidate miRNA selection and unbiased miRNA-target identification methods.

Keywords: 3′UTR reporter assay; FOXO; MicroRNA; MicroRNA target identification.
