Conversion of the BLV pre-miRNA to a 5′-monophosphate does not precede Dicer processing. (A) 5′-end characterization of BLV-pre-miR-B4. Northern blot analysis was performed on small RNAs purified from either HEK293T or HEK293T NoDice cells transfected with the pBLV-B4 miRNA expression vector and treated with the indicated enzymes. (B) Graphical representation of the northern blot analysis band density ratio (Terminator+/Terminator−) of BLV-pre-miR-B4 and tRNA in either HEK293T cells (WT) and HEK293T NoDice cells (NoDice) relative to the 5S RNA. The bars represent the average ratio of three independent biological replicates +/− the standard deviation (n = 3).
