Letter to the editor: Does dicer expression affect shRNA processing?
Elevated Dicer and Drosha mRNA levels have been documented across a range of tumor types (including ovarian carcinoma) by a number of investigators without any demonstrable correlation with patient survival nor evidence of interference with shRNA processing. A recent publication by Merritt et al. (NEJM 359(25):2641-50, 2008) reporting their findings in patients with ovarian carcinoma reach opposite conclusions. Further study will be needed to resolve this issue.
