The efficiency of genome editing with VLPs depends on the Cas9 packaging into VLPs, the process mediated by the viral Gag protein. To improve the packaging of Cas9 into NanoMEDIC VLPs, plasmid constructs for Cas9 and Gag expression were modified by adding the HIV Rev response element (RRE), which was expected to increase the nuclear export of RRE-containing transcripts into the cytosol via the Rev accessory protein, as described for a Vpr-Cas9-based VLP system. The Cas9 and Gag protein levels in cell lysates were found to increase upon cotransfection with either the Rev-expressing plasmid or the empty control plasmid. The effect was independent of the presence of RRE in the transcript. Moreover, AP21967-induced dimerization of FRB and FKBP12, but not plasmid modification with RRE and/or cotransfection with the Rev-expressing plasmid, was shown to play the major role in Cas9 packaging into NanoMEDIC VLPs.
