2015 ), overexpression of the wild-type hDcr protein in NoDice/ΔPKR cells expressing the pCD-RLuc dsRNA insert did not induce repression of RLuc expression, when compared to the empty vector negative control, while a highly significant ( P = 0.004) level of inhibition of RLuc expression was detected in cells coexpressing the N1hDcr mutant, which shows a significantly enhanced ability to generate siRNAs from dsRNA substrates ( Kennedy et al. 2015 ).
