Abstract:
MicroRNAs are small noncoding RNAs that regulate gene expression at the posttranscriptional level. Proteoglycans are glycoproteins characterized by covalent attachment of a glycosaminoglycan chain, which have been identified as regulatory targets of microRNAs in a physiological and pathophysiological context. We present a strategy and detailed methods for the functional analysis of microRNA regulation of proteoglycans using human cancer cells as an application example. The experimental setup includes in silico microRNA target prediction, transfection of cancer cells with microRNA precursors, validation of target regulation by qPCR, flow cytometry and luciferase reporter assays, and an example for functional analysis and phenotype confirmation by complementation analysis.
