Abstract
Micro RNAs (miRNAs) are small RNAs processed from longer precursor RNA transcripts that can fold back on themselves to form Watson-Crick paired hairpin structures. Once processed from the longer molecule, the small RNA is much too short to code for proteins but can play other very important roles, like gene regulation. The phenomenon of RNA interference was initially observed by Napoli and Jorgensen in transgenic petunia flowers, where gene suppression was observed after introducing a transgene of chalcone synthase (CHS) belonging to the flavonoid biosynthesis pathway. miRNAs were first discovered for their roles in development but it has quickly become evident that they have causal roles in cancer as well. miRNA can also be used to manipulate genes for the investigation of carcinogenesis. Single-cell transcriptome profiling studies in our laboratory suggest that carcinogenesis often is the result of the malfunction of multiple members of a molecular pathway. Here, we describe a protocol to manipulate multiple cancer-related genes in a single human cell to investigate how multiple genes interact during carcinogenesis.
