Q
A

A morpholino, also known as a morpholino oligomer and as a phosphorodiamidate morpholino oligomer (PMO), is type of oligomer molecule (colloquially, an oligo) used in molecular biology to modify gene expression. The molecular structure has a backbone of methylenemorpholine rings and phosphorodiamidate linkages.

A Brief Introduction to Morpholino Antisense

eg:

The protein envelope surrounding the virus was then reversed, in a process called antisense.

A

Morpholino oligos are advanced tools for blocking sites on RNA to obstruct cellular processes. A Morpholino oligo specifically binds to its selected target site to block access of cell components to that target site. This property can be exploited to block translation, block splicing, block miRNAs or their targets, and block ribozyme activity.

Antisense therapy is a form of treatment for genetic disorders or infections. When the genetic sequence of a particular geneis known to be causative of a particular disease, it is possible to synthesize a strand of nucleic acid (DNA, RNA or a chemical analogue) that will bind to the messenger RNA (mRNA) produced by that gene and inactivate it, effectively turning that gene “off”. This is because mRNA has to be single stranded for it to be translated. Alternatively, the strand might be targeted to bind a splicing site on pre-mRNA and modify the exon content of an mRNA.

This synthesized nucleic acid is termed an “antisense” oligonucleotide (ASO) because its base sequence is complementary to the gene’s messenger RNA (mRNA), which is called the “sense” sequence (so that a sense segment of mRNA “ 5’-AAGGUC-3’ “ would be blocked by the anti-sense mRNA segment “ 3’-UUCCAG-5’ “).

Antisense oligonucleotides have been researched as potential drugs for diseases such as cancers (including lung cancer,colorectal carcinoma, pancreatic carcinoma, malignant glioma and malignant melanoma), diabetes, Amyotrophic lateral sclerosis (ALS), Duchenne muscular dystrophy and diseases such as asthma, arthritis and pouchitis with an inflammatorycomponent. As of 2014 two antisense drugs have been approved by the U.S. Food and Drug Administration (FDA), fomivirsen(marketed as Vitravene) as a treatment for cytomegalovirus retinitis and mipomersen (marketed as Kynamro) for homozygousfamilial hypercholesterolemia.

Antisense RNA (asRNA) is a single-stranded RNA that is complementary to a messenger RNA (mRNA) strand transcribedwithin a cell. Some authors have used the term micRNA (mRNA-interfering complementary RNA) to refer to these RNAs but it is not widely used.

Antisense RNA may be introduced into a cell to inhibit translation of a complementary mRNA by base pairing to it and physically obstructing the translation machinery. This effect is therefore stoichiometric. An example of naturally occurring mRNA antisense mechanism is the hok/sok system of the E. coli R1 plasmid. Antisense RNA has long been thought of as a promising technique for disease therapy; the first antisense therapeutic to reach the market is the drug fomivirsen, approved in 1998. Mipomersen was approved in the united states in 2013. One commentator has characterized antisense RNA as one of “dozens of technologies that are gorgeous in concept, but exasperating in [commercialization]”. Generally, antisense RNA still lack effective design, biological activity, and efficient route of administration.

The effects of antisense RNA are related with the effects of RNA interference (RNAi). The RNAi process, found only in eukaryotes, is initiated by double-stranded RNA fragments, which may be created by the expression of an anti-sense RNA followed by the base-pairing of the anti-sense strand to the target transcript. Double-stranded RNA may be created by other mechanisms (including secondary RNA structure). The double stranded RNA is cleaved into small fragements by DICER, and then a single strand of the fragment is incorporated into the RNA-induced silencing complex (RISC) so that the RISC may bind to and degrade the complementary mRNA target. Some genetically engineered transgenic plants that express antisense RNA do activate the RNAi pathway. This processes resulted in differing magnitudes of gene silencing induced by the expression of antisense RNA. Well-known examples include the Flavr Savr tomato and two cultivars of ringspot-resistant papaya.

Transcription of longer cis-antisense transcripts is a common phenomenon in the mammalian transcriptome. Although the function of some cases have been described, such as the Zeb2/Sip1 antisense RNA, no general function has been elucidated. In the case of Zeb2/Sip1, the antisense noncoding RNA is opposite the 5’ splice site of an intron in the 5’UTR of the Zeb2 mRNA. Expression of the antisense ncRNA prevents splicing of an intron that contains a ribosome entry site necessary for efficient expression of the Zeb2 protein. Transcription of long antisense ncRNAs is often concordant with the associated protein-coding gene, but more detailed studies have revealed that the relative expression patterns of the mRNA and antisense ncRNA are complex.

Q

Translation Blocking?

A

By sterically blocking the translation initiation complex, Morpholinos can knock down expression of many target sequences completely enough that after waiting for existing protein to degrade, the target protein band disappears from Western blots. Unlike many antisense types (e.g. siRNA, phosphorothioates), Morpholinos generally do not cause degradation of their RNA targets; instead, they block the biological activity of the target RNA until that RNA is degraded naturally, which releases the Morpholino. This means that RT-PCR is not suitable for assaying translation blocking by Morpholinos.

Q

Splice Blocking?

A

By blocking sites involved in splicing pre-mRNA, Morpholinos can be used to modify and control normal splicing events. This activity can be conveniently assayed by RT-PCR, with successful splice-modification appearing as changes in the RT-PCR product band on an electrophoretic gel. The band might shift to a new mass or, if splice-modification triggers nonsense-mediated decay of the transcript, the band will lose intensity or disappear.

Q

How to Delivery Morpholino?

A

Like all gene knockdown reagents, Morpholinos must be actively delivered into most cells. Morpholinos can be delivered into cultured cells by a variety of methods, including scrape-loading of adherent cells, electroporation, and even microinjection. However, our Endo-Porter delivery reagent generally gives excellent delivery in cultured cells in terms of the amount of Morpholino delivered per cell, even distribution throughout a population of cells, reproducibility of delivery and non-toxicity. For animal experiments our Vivo-Morpholinos with their attached delivery moiety enter into cells from the blood after i.v. administration or enter cells in tissues surrounding local injections; they are also the most convenient antisense oligos for use in cell cultures or explants, as they do not require any additional agent for cytosolic delivery.

Q

The Structure od Morpholino.

Segment of a Morpholino-RNA heteroduplex, 8-mer shown:

A

A Morpholino oligo is radically different from natural nucleic acids, with morpholine rings replacing the ribose or deoxyribose sugar moieties and non-ionic phosphorodiamidate linkages replacing the anionic phosphates of DNA and RNA. Each morpholine ring suitably positions one of the standard DNA bases (A,C,G,T) for pairing, so that a 25-base Morpholino oligo strongly and specifically binds to its complementary 25-base target site in a strand of RNA via Watson-Crick pairing. Because the uncharged backbone of the Morpholino oligo is not recognized by enzymes or signaling proteins, it is completely stable to nucleases and does not trigger an innate immune response through the Toll-like receptors. This avoids oligo degradation, inflammation and interferon induction, which are problems commonly encountered with other gene knockdown reagents.

Q

Some General Advice for Morpholino Experiments: Assessing delivery

A

As with all gene knockdown agents, effective delivery of Morpholinos is crucial. While confirming delivery is not crucial for experiments using embryonic microinjection, confirming delivery is important for experiments with cultured cells. Our Endo-Porter delivery reagent generally gives simple, reliable delivery for most cell types. You can assess whether you are getting good delivery into the cytosol of your cells by using a fluorescent-tagged Morpholino. We recommend you use our inexpensive fluorescein-tagged Standard Control oligo for this purpose.

When using a fluorescent Morpholino to confirm delivery, start with a concentration of 10 microMolar Morpholino oligo in the culture medium. This is a high enough concentration that after 16 hours the fluorescent-tagged Morpholino should be visible in the cytosol by fluorescence microscopy. An inverted fluorescent microscope is the best choice for observing cells in culture plates. Observe live (unfixed) cells. Use a dry objective lens with the highest available numerical aperture to gather as much light as possible from the cells. Successful delivery is manifested by diffuse fluorescence throughout the cytosol. Punctate fluorescence usually indicates that the oligo is trapped in endosomes, so ignore punctate spots and look for the diffuse fluorescence.

For actual experiments delivering your custom-sequence Morpholino with Endo-Porter you generally need a concentration of only 1 to 5 microMolar for effective steric blocking of most mRNAs.

Q

Advice for Morpholino Experiments: Solubility and Morpholinos

A

Though Morpholino oligos are much more soluble than other non-ionic structural types (such as PNAs), some Morpholinos with high G content (>30%) do have limited solubility. Also, attachment of our red-emitting lissamine fluor sometimes decreases oligo solubility. Freeze-thaw cycles or long-term storage at 4C can cause slow precipitation or container association of Morpholinos and decrease the solution activity. This can sometimes be reversed by heating 5 min at 65C or by autoclaving (use the liquid cycle). We recommend that Morpholinos be stored at room temperature, which helps to keep the oligos in solution; be careful to avoid drying out the oligos. Making Morpholino stock solutions at or below 1 milliMolar helps to avoid solubility problems.

DNA, RNA, and most gene knockdown reagents are typically stored in an ice bath during experiments to minimize degradation by nucleases. Because Morpholinos are completely resistant to enzymatic degradation and aqueous solutions are chemically stable indefinitely at room temperature, we recommend that during your experiments you keep your stock solutions of Morpholinos at room temperature. Chilling your stock solutions in an ice bath simply risks causing the Morpholino to precipitate out.

If you are keeping Morpholinos as aqueous stock solutions and notice a decrease in antisense activity of the solution, you can autoclave the stock (use the liquid cycle of the autoclave). The oligos are very heat stable and can tolerate several rounds of autoclaving without degradation. Often autoclaving will revive a stock that has lost some activity due to aggregation of oligo.

For long-term storage your Morpholino stock solutions are best stored lyophilized, The next-best choice is storage in solution at room temperature. Wrapping the closure of the vial in Parafilm can help minimize microbial contamination and evaporation. Be careful to keep the oligo from drying out, as it can be difficult or impossible to redissolve a dried-down oligo (though freeze-dried oligos dissolve fairly easily). Keeping the vial in a dark box is a good practice, as fluor-labeled oligos can photobleach in light.

These precautions are more than needed for most sequences, but their routine use helps to avoid unpleasant surprises in the event you encounter a sequence with low solubility.

Q

Why use a Vivo-Morpholino?

A

Vivo-Morpholinos* are the knockdown, exon-skipping or miRNA blocking reagent of choice for in vivo experiments. Outstanding results can be achieved systemically with intravenous (I.V.) injection, and modest systemic delivery achieved with Vivo-Morpholinos by intraperitoneal (I.P.) injection. Efficient localized delivery can be achieved by injecting the Vivo-Morpholino directly into the area of interest. Vivo-Morpholinos are also effective and easy to use in cultures.

Q

Vivo-Morpholinos get the job done by combining two important parts:

Reference:

http://www.gene-tools.com/vivomorpholinos

A

A Vivo-Morpholino is comprised of a Morpholino oligo with a unique covalently linked delivery moiety, which is comprised of an octa-guanidine dendrimer. It uses the active component of arginine rich delivery peptides (the guanidinium group) with improved stability and reduced cost. The Vivo-Morpholino is assembled by coupling the vivo-delivery group to a Morpholino while the oligo is still bound to its synthesis resin, allowing excellent purification by washing the solid-phase resin. Vivo-Morpholinos must be chosen prior to synthesis and cannot be added later because the vivo-delivery group is added to a Morpholino prior to cleavage from its synthesis resin.

Q

In vivo methods

A

For best systemic delivery results the injection method of choice is i.v. although i.p. can also be used. The maximum suggested dosage in mammals is 12.5 mg/kg in a 24 hour period; dosing can be repeated daily, however, the sensitivity of organisms to the toxicity of the delivery moiety can vary depending on the type and health of the organism, so it is important to check the tolerance of your organism prior to dosing a group of animals. Local injections should be performed with reduced doses.

For short term experiments (3-day) Gene Tools suggests two days of i.v. injections at 12.5 mg/kg followed by analysis on day 3. Long term experiments should be optimized for your specific goals; however you can try starting with a loading dose equivalent to the short term experiment and then adjust dosage and times to find an optimum for continued delivery. Vivo-Morpholinos were optimized using 4 to 10 week old C57 Black mice and up to 20 mg/kg injections with successful outcomes. However, we have found that younger or older mice do not tolerate Vivo-Morpholinos as well and may require substantially lower doses. In addition the use of compromised mice, such as those with less robust genetic backgrounds, may require further dose limitations.

Q

Cell culture methods

A

Vivo-Morpholinos are very simple to use in cultured cells. The typical concentration range for Vivo-Morpholinos in cell culture is 1 to 10 micromolar of Morpholino oligo in the culture medium. Concentrations higher than 10 micromolar could be toxic to cells. The protocol is as follows: add an appropriate amount of the solution to the culture medium on cells to reach the desired final concentration of Morpholino oligo, swirl to mix and harvest the cells as early as 24hr after treatment. It is not necessary to change the culture medium after adding oligos if the oligos are not toxic to the cells. If toxicity is observed, the oligo containing medium can be removed 2 to 4 hrs after treatment and fresh medium added. Serum significantly inhibits the efficacy of Vivo-Morpholinos so use a lower serum concentration if the cells tolerate it. The effect of splice-targeted oligos can be detected by reverse transcriptase PCR. The effect of translation blocking oligos can be assessed by analyzing protein levels by Western blot. The time needed to detect changes in the amount of protein translated from the targeted RNA will vary depending on the half-life of the protein, as preexisting protein must degrade for a knockdown to be evident.
