A lentiviral microRNA-based system for single-copy polymerase II-regulated RNA interference in mammalian cells.

@article{citeulike:685466, abstract = {The advent of RNA interference has led to the ability to interfere with gene expression and greatly expanded our ability to perform genetic screens in mammalian cells.
