Assay for activation or inhibition of the small-interfering RNA (siRNA) pathway via control of enhanced green fluorescent protein (EGFP) through lentiviral expression of an EGFP-targeting short hairpin RNA. In the presence of small molecule activators of the siRNA pathway, a decreased level of fluorescence is detected, while siRNA pathway inhibitors will lead to an increase in fluorescence
