The PML-RARα fusion gene disrupts the retinoic acid differentiation signal in a range of leukaemia types, promoting proliferation. We designed a shRNA to target the fusion mRNA, and the shRNA expression cassette was delivered via lentiviral transduction. Delivery of this shRNA significantly down regulated the target mRNA, with effects also evident at the protein level. When combined with ATRA administration, this down regulation of the fusion gene strongly inhibited proliferation in the NB4 PML cell line.
