MicroRNA Profiling of Cell Lines and Xenografts by Quantitative PCR : MicroRNA Expression Level Determination by qPCR

Methods Mol Biol. 2023:2595:101-114. doi: 10.1007/978-1-0716-2823-2_7.

Abstract

MicroRNAs (miRNAs) are small non-coding RNAs that play essential roles in regulating gene expression at the post-transcriptional level, possibly at any level of the cellular physiology. Furthermore, their deregulation has been observed in a myriad of human diseases including cancer. Therefore, miRNA-based therapies are directed to inhibit the function of oncogenic miRNA or to restore the function of tumor-suppressive miRNAs. Here, we describe how to analyze miRNA levels after the transfection of miRNAs of interest using different transfection reagents or intravenous administration of miRNAs conjugated to lipid nanoparticles in cell lines and in mouse xenograft models.

Keywords: Cancer; Real-time quantitative PCR (qPCR); miRNA-based therapies; microRNA.
