High-throughput Screening for Chemical Modulators of Post-transcriptionally Regulated Genes

Overview

This article describes a cell-based reporter gene assay designed to screen chemical libraries for compounds that modulate post-transcriptional control mechanisms through the 3’ untranslated region (UTR) of transcripts. The methodology involves cloning the 3’ UTR into a luciferase control reporter plasmid and integrating it into a relevant cell line.
