Abstract |
MicroRNAs have the ability to alter and regulate multiple genes, including RTK family members, making them an attractive approach for molecular therapeutic development. We use a pCDNA6.2-EmGFP-microRNA expression vector to overexpress individual mature microRNA and then transfer the expression cassette into a single, inducible lentiviral vector (pINDUCER20). We successfully use this system to create a pINDUCER-EmGFP-miRNA27a expression vector and generate a stable head and neck cancer cell line (UM-SCC-22A) that inducibly expresses miRNA-27a, resulting in targeted epidermal growth factor receptor down regulation. In this chapter, we describe the protocol for engineering the pINDUCER-EmGFP- microRNA expression vector, producing lentiviral particles for target cell infection, and evaluating downregulation of gene expression.
