NOL7 subnuclear localization is dynamically regulated by changes in RNA composition. 293T cells were stably transfected with NOL7-GFP and treated with RNase A (100 μg/ml, 2 hours), DNase I (100 μg/ml, 2 hours), actinomycin D (0.05 μg/ml, 4 hours), or α-amanitin (50 μg/ml, 4 hours) to specifically deplete individual nucleic acid species. Treatment with DNase (total DNA), RNase (total RNA), ActD (rRNA), or α-amanitin (mRNA) was performed and localization of NOL7 was confirmed by fluorescent microscopy of the GFP tag.
