|Vivo-Morpholinos as switching molecules for virally-delivered targets in mice||
The authors of this new paper use an engineered viral vector (AAV) to express a secreted antibody. They make a version where the antibody is out-of-frame and a Morpholino is used to skip an exon, bring the antibody in-frame and switch on its functional expression; the target is a payload of the AAV and the switching molecule is the Morpholino. This use of Morpholinos as switching molecules in engineered systems has great therapeutic potential. In the same paper, they controlled the expression of their AAV cargo with a Vivo-Morpholino after delivery into a mouse.

|Generating Zebrafish RNA-Less Mutant Alleles by Deleting Gene Promoters with CRISPR/Cas9||
A frameshift mutation did not phenocopy the corresponding Morpholino. To avoid transcriptional adaptation (genetic compensation), the authors made mutants with deleted promoters, eliminating the NMD transcript that would trigger transcriptional adaptation.
