| Splicing outcomes: targeting for exon skipping or intron inclusion |
Someone asked me why some Morpholinos usually cause exon skips and others cause intron inclusions... U1 and U2 (or U11 and U12) snRNPs mark the positions on pre-mRNA of the splice junctions for the spliceosome. There is a U1 snRNP that binds in the intron near the e2i2 junction and a U2 snRNP that binds on the other side of the intron at the i2e3 junction. Figure 1 |

| RNA therapeutics: beyond RNA interference and antisense oligonucleotides |
Nice review, a few years old, describing Morpholinos and other antisense as therapeutics. RNA therapeutics: beyond RNA interference and antisense oligonucleotides. |

| A nucleic acid binder, poor at binding MO |
Sen D, Patel G, Patel SS. Homologous DNA strand exchange activity of the human mitochondrial DNA helicase TWINKLE. Nucl Acids Res. 2016;[Epub ahead of print] doi:10.1093/nar/gkw098 https://nar.oxfordjournals.org/content/early/2016/02/16/nar.gkw098.full DNA binds in the protein TWINKLE, but Morpholino is very poor at that binding. No surprise, it's likely due to lack of charge, but this is a nice published example of the low-binding characteristic. |

| Antisense oligonucleotide-directed inhibition of nonsense-mediated mRNA decay |
Here's an interesting technique: inhibition of nonsense-mediated decay with oligos. I don't think the antisense oligos were Morpholinos. Antisense oligonucleotide-directed inhibition of nonsense-mediated mRNA decay. http://www.nature.com/nbt/journal/vaop/ncurrent/full/nbt.3427.html |

| Use of Morpholinos to Regulate Gene Expression in the Brain |
Here is a review of tools to manipulate gene expression in the brain. Just before the Conclusion is the section "Use of Morpholinos to Regulate Gene Expression in the Brain".

| Morpholino-driven gene editing: A new horizon for disease treatment and prevention |
Though I did in the early days of commercial Morpholinos, now I generally don't enter review articles into the Morpholino database. This one came along and I want to keep a record of it, particularly for the list of diseases in Table 1. So, it goes here. Subbotina E, Koganti SR, Hodgson-Zingman D, Zingman LV. Morpholino-driven gene editing: A new horizon for disease treatment and prevention. Clin Pharmacol Ther. 2015 Oct 16. doi: 10.1002/cpt.276. [Epub ahead of print] |
