    Default Gene editing via nano particle chemtrails?: Science-proven fact emerges

    CRISPR-carrying nanoparticles edit the genome



    In a new study, MIT researchers have developed nanoparticles that can deliver the CRISPR genome-editing system and specifically modify genes in mice. The team used nanoparticles to carry the CRISPR components, eliminating the need to use viruses for delivery.

    Using the new delivery technique, the researchers were able to cut out certain genes in about 80 percent of liver cells, the best success rate ever achieved with CRISPR in adult animals.

    "What's really exciting here is that we've shown you can make a nanoparticle that can be used to permanently and specifically edit the DNA in the liver of an adult animal," says Daniel Anderson, an associate professor in MIT's Department of Chemical Engineering and a member of MIT's Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science (IMES).

    One of the genes targeted in this study, known as Pcsk9, regulates cholesterol levels. Mutations in the human version of the gene are associated with a rare disorder called dominant familial hypercholesterolemia, and the FDA recently approved two antibody drugs that inhibit Pcsk9. However, these antibodies need to be taken regularly, and for the rest of the patient's life, to provide therapy. The new nanoparticles permanently edit the gene following a single treatment, and the technique also offers promise for treating other liver disorders, according to the MIT team.

    Anderson is the senior author of the study, which appears in the Nov. 13 issue of Nature Biotechnology. The paper's lead author is Koch Institute research scientist Hao Yin. Other authors include David H. Koch Institute Professor Robert Langer of MIT, professors Victor Koteliansky and Timofei Zatsepin of the Skolkovo Institute of Science and Technology, and Professor Wen Xue of the University of Massachusetts Medical School.

    Targeting disease

    Many scientists are trying to develop safe and efficient ways to deliver the components needed for CRISPR, which consists of a DNA-cutting enzyme called Cas9 and a short RNA that guides the enzyme to a specific area of the genome, directing Cas9 where to make its cut.

    In most cases, researchers rely on viruses to carry the gene for Cas9, as well as the RNA guide strand. In 2014, Anderson, Yin, and their colleagues developed a nonviral delivery system in the first-ever demonstration of curing a disease (the liver disorder tyrosinemia) with CRISPR in an adult animal. However, this type of delivery requires a high-pressure injection, a method that can also cause some damage to the liver.

    Later, the researchers showed they could deliver the components without the high-pressure injection by packaging messenger RNA (mRNA) encoding Cas9 into a nanoparticle instead of a virus. Using this approach, in which the guide RNA was still delivered by a virus, the researchers were able to edit the target gene in about 6 percent of hepatocytes, which is enough to treat tyrosinemia.

    While that delivery technique holds promise, in some situations it would be better to have a completely nonviral delivery system, Anderson says. One consideration is that once a particular virus is used, the patient will develop antibodies to it, so it couldn't be used again. Also, some patients have pre-existing antibodies to the viruses being tested as CRISPR delivery vehicles.

    In the new Nature Biotechnology paper, the researchers came up with a system that delivers both Cas9 and the RNA guide using nanoparticles, with no need for viruses. To deliver the guide RNAs, they first had to chemically modify the RNA to protect it from enzymes in the body that would normally break it down before it could reach its destination.

    The researchers analyzed the structure of the complex formed by Cas9 and the RNA guide, or sgRNA, to figure out which sections of the guide RNA strand could be chemically modified without interfering with the binding of the two molecules. Based on this analysis, they created and tested many possible combinations of modifications.

    "We used the structure of the Cas9 and sgRNA complex as a guide and did tests to figure out we can modify as much as 70 percent of the guide RNA," Yin says. "We could heavily modify it and not affect the binding of sgRNA and Cas9, and this enhanced modification really enhances activity."

    Reprogramming the liver

    The researchers packaged these modified RNA guides (which they call enhanced sgRNA) into lipid nanoparticles, which they had previously used to deliver other types of RNA to the liver, and injected them into mice along with nanoparticles containing mRNA that encodes Cas9.

    They experimented with knocking out a few different genes expressed by hepatocytes, but focused most of their attention on the cholesterol-regulating Pcsk9 gene. The researchers were able to eliminate this gene in more than 80 percent of liver cells, and the Pcsk9 protein was undetectable in these mice. They also found a 35 percent drop in the total cholesterol levels of the treated mice.

    The researchers are now working on identifying other liver diseases that might benefit from this approach, and advancing these approaches toward use in patients.

    "I think having a fully synthetic nanoparticle that can specifically turn genes off could be a powerful tool not just for Pcsk9 but for other diseases as well," Anderson says. "The liver is a really important organ and also is a source of disease for many people. If you can reprogram the DNA of your liver while you're still using it, we think there are many diseases that could be addressed."

    "We are very excited to see this new application of nanotechnology open new avenues for gene editing," Langer adds.

    ~~~~~~~~~~~~~~~

    Understand that black ops science exploded into manifold directions by the end of WWII and was noted, at the time (end of WWII, 1946) to be moving at a rate of 50 years of development faster than every year of open public science development. It went 'back' so as to hide the developments from the enemy, whatever that means.

    The open sciences and development of war machinery stopped, regarding production of devices but..development, the science, exploded into being with just as much torrents of money and effort being thrown into it as the war machine itself, in the early 1940s. Basically, unlimited funds but mostly research, and all black ops. Corporations unhinged and out of control, which is where the mess we are in today comes from.

    Essentially, hidden black ops are so far ahead of what you see, that it borders on magic, which is why you see the comment about Ben rich, the former head of lock heed martin's skunk works saying (I paraphrase) "We can do anything, anything at all you can possibly imagine, but it would take and act of god for you to be able to see it."

    Black ops technology advance are estimate in that sort of math, to be at least 2000, if not 3000 years ahead what you see today. And that is with the crazy unlimited and unhinged near exponential explosion of technology that is happening today. thus the 'magic' comment.

    So yeah, gene editing and modifying chemtrails? Not just possible but now the science of that reality is open, that it is real, and proven and shown to the public.

    The requisite parts for this crazy sounding story we've all heard..ridiculed by the press and ridiculed by most people with no exposure to the complex data of the alternative news and reports... the components for gene editing nano particle chemtrails are now real and on the table....

    What does that say about the rest of the "crazy stories"?

    Good for you, Langer.
    For some strange reason, I'm not feeling the same excitement!?!?
    Must be in my genes.
    No worries, I'm sure Langer will take care of that, lickity-split!

    If this gene edition through nanoparticles is going public, it means it has been going on for quite a long time already, but in secret.

    I Wonder how our genetic has already been changed without our agreement.

    KOCH villains never had the good of mankind on their agenda before, why now?
    Could it be to control the patient as well. Couldn't they reduce the g-nome to just lower level intelligence and have the patient become a docile workbot?

    Considering they have no idea about what they are doing or even how genes deliver form to intended function, this splicing technology could easily lead them into trouble. Imagine that crispy critter getting out in the wild and into the biosphere, splicing merrily on its way, reproducing and altering on the fly! Can hardly wait until there is no liver damaging disease in the entire world of living things.

    So glad they keep advancing in ignorance, blindly tinkering with things they have no clue about, except some theory and a few assumptions.
    Counter to our sovereign hope we're enthralled in mind by empty rote of frozen thoughts like knots in rope.

    I'd been going to say pretty much the same thing, except in only 4/5 words.

    ie. They're literally ******* insane!
