Mirtrons, a subclass of intronic microRNAs, offer an alternative RNA interference (RNAi) mechanism by bypassing Drosha processing. This protocol details the design and production of mirtron-based constructs aimed at achieving efficient gene knockdown. By embedding mirtrons in the 5' untranslated region (UTR) of a transgene, we evaluated processing efficiency and RNAi activity. The compact size of mirtrons facilitates concurrent gene knockdown and supplementation within a single adeno-associated virus (AAV) vector. Our findings present a novel strategy for gene regulation in therapeutic and research applications.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
