What's a gene drive?

Ғылым және технология

A gene drive is a radical new way of re-engineering the genetic makeup of an entire species - including harmful insects like the mosquito. But as the technology steams head, fueled by powerful gene editing techniques coming out of synthetic biology like CRISPR Cas9, what are the risks, and how can we ensure that it is used safely and responsibly without causing harm?

    I agree that scientists do not know enough and that there is an inherent bias in scientists who do this research as often the push is to keep funding or make money for a company. There is a very powerful interview with Caius Romans who worked as a head researcher in genetic engineering for Monsanto and JR. Simplot (for 26 years) until he had a change of heart. This is what he says in a recent interview with Sustainable Pulse: It is amazing that the USDA and FDA approved the GM potatoes by only evaluating our own data. How can the regulatory agencies assume there is no bias? When I was at J.R. Simplot, I truly believed that my GM potatoes were perfect, just like a parent believes his or her children are perfect. I was biased and all genetic engineers are biased. It is not just an emotional bias. We need the GM crops to be approved. There is a tremendous amount of pressure to succeed, to justify our existence by developing modifications that create hundreds of millions of dollars in value. We test our GM crops to confirm their safety, not to question their safety. "

    The particular insight on mosquitos in this video I found more ethically acceptable, genetically modifying the mosquito to become resistant to the malaria carrying parasite (Plasmodium), previous talk with gene-drives were talking about ending the existence of mosquitos completely, and other species that were considered pests. Something I feel could eventually compromise the environment and our biosphere and ecosystems around the world, we are so far from knowing how organisms interact, or even how micro-organisms could interact on each other in their native environment, some could be vital to other forms of life or even evolution itself. Man indeed has harnessed the power to wipe all life from the earth, and not just with nuclear technology, but also with CRISPR gene editing. But man also has the power to do good with this technology take nuclear fusion reactors for example cleaner energy (not 100% clean), sadly nuclear bombs were the precursor to reactors, being used in 1945. Yet I am hopeful that the path we will take, will be one that cures deadly disease, genetic or otherwise including cancer, making it a thing of the past. But using it to wipe a species from the face of the earth, I feel would be a step too far. Unless of course that species was introduced to an alien environment and is causing damage to that particular environment and its species, destroying its natural ecosystem. The Alien environment I am particularly concerned with is the Austr-alien (forgive the play on words), The deadly cane toad for example, poisoning and killing a lot of Australia's natural wild inhabitants, to the point of extinction. Rather than destroy the invasive and deadly species of toad that is not native to Australia, maybe it could be genetically modified by CRISPR gene drives to lose it's parotid glands, effectively making it harmless to other species, like the endangered King Brown Snake and other species that feed on toads. CRISPR has much to offer the future of medicine, let us hope its for the benefit of the planet and all its creatures and not just for those who can afford it. facebook.com/HistoryInPictures/photos/a.1417075835221721/3155888264673794/ - This is indeed the most dangerous animal in the world.

    Good points, all. The main problem with all of this, ethically, morally, even spiritually, is that someone somewhere could, should, (or should not), but always will (or will not), absolutely find a defensible - possibly even noble - rationale for either eradicating any organism or class of organisms entirely, or for modifying it for a beneficial or malicious purpose. And that person’s or organization’s objective outcome sought is corrupted from the moment the Gene Drive thought experiment begins. Everything humankind does is corrupted, and not just by striving for common good or common evil for ourselves individually, our kin, our tribe, nation, or species. The worst case is not even that which may occur by a psychopath’s or sociopath’s completely personal/selfish desire. Humankind is corrupted by its inherent ignorance and inherent lack of foresight. And this problem is unsolvable by humankind. This is because time is observed linearly and in experienced by humankind in only the current moment. Everything else about our experience of time is either projection or recollection. As such, humankind cannot and does not have the ability to fully comprehend the breadth or number of potential impacts that an action, word, or thought has on the future. We can only project (mathematically model) the potential impacts of outcomes that we consider - and the fact that we don’t consider all possible impacts/outcomes, and therefore cannot model them, further corrupts the projections that we do make.

    @@michaelfoxbrass I agree, ignorance, and corruption is everywhere, and almost every advancement that humankind has made, can come with great cost, since the invention of the wheel, the discovery of gunpowder, the Write brothers taking to the skies, and nuclear technology, humankind has used all these discoveries and more, normally in the name of science and advancement, not just to benefit mankind, but also to wreak havoc, and to wage war, to destroy and kill, vast numbers of people wiped out with a single bomb. How would this technology differ? How long before it gets perverted and is used to wipe out a particular race of human, who has a specific skin pigmentation, or eye colour, what if it was so well guarded that it never fell into the hands of a megalomaniac, but instead was used it to wipe out a particular species with good intentions, maybe a certain bacteria of virus, but the specific genome targeted happened to be shared, buried deep within 30% of human DNA, or what if the gene drive mutated, became a virus and damaged or even wiped out humans. I was watching Unnatural Selection on Netflix, when this technology was discovered, Bio-hackers were buying and sometimes distributing DIY DNA Editing kits online, globally, why was this allowed to happen? For all the amazing things this technology can do, and some of it is absolutely beneficial to mankind, like the boy in the aforementioned program, who's inherited blindness caused by a gene he inherited off both parents, was cured using CRISPR, but for all the good it can do, you have a equal amount of harm that can come from it, if they intend to continue the gene drive development, then stringent safeguards, safety measures and thought needs to go at the forefront of its advancement. They need to consider all options both good and bad, to a point that before anything is tested, they can be sure its done in a safe environment, and any changes they make, or mistakes that may occur, can be repaired or reverse engineered to become safe and inert. I am all for curing sickness, disease, or genetic abnormalities, and would love to see genetic afflictions wiped out, so that the sufferers have a chance at a normal life, a better quality of life. At the same time, imagine if this technology existed some 20 years before WW2, D-IX methamphetamine based drug would not have been the only thing tested on Hittler's troops, or on those born 20 years before the war, genetically enhanced humans may have been commonplace today. We has humans have trouble knowing when or even where to draw the line, yes you could extend life, live to 150-200 years, engineer the body to last and be productive during a 150-200 year lifespan, turn on and off the ability to procreate, keeping human levels at a stable and sustainable rate, ensuring a better quality of life for those that have to share the finite amount of resources, you could increase crops, engineered to last longer, grow bigger, resist pests and make sure every single person on the planet is fed. You could bring back a species from the edge of extinction, or even some that have already perished, you could correct the mistakes we have made by introducing species to our environments, and like I said engineer a deadly frog so that it loses its poison glands and is no longer a danger to indigenous wildlife. You could redesign a planet with humans working together, to discover what lies beneath the depths of the deepest oceans, or discover new ways to travel into the darkest regions of space. Doubling the life span, and I mean with a good quality of life, you could double the potential of the human species. With more technological advancement we could evolve into planet hopping civilisation, able to terraform and colonise a galaxy, ensuring survival of the human race, and even other lifeforms that develop here on earth. I would rather live in a world like that, than go galloping into a future in which sustainability and greed could end up being our downfall, and in its wake a world left permanently broken, unable to recover from the burden we have placed upon it. That being said, one mistake, one sociopath, one megalomaniac, one psychopath, and the world could just go pop anyway, and us with it.

    I understand that at the molecular level a CRISPR mediated gene drive works by copying the altered gene (and the drive containing CAS enzyme, and guide RNA) into the other chromosome containing the wild type allele through homology directed repair...In case of a suppressive drive that is designed to render the offsprings infertile or die before reproduction .. In a typical suppression drive, Where is this copying and homology directed repair happening. In the somatic cells of one of the “parents”, or the germline cells of the parents during gametogenesis? If the drive and altered gene is copied in the somatic cells of the organism that was inserted in, then wouldn't the organism perish/or not be able to reproduce, thus unable to pass on the drive/altered gene? Or is this copying happening in the Zygote off the offspring (thus all its somatic cells), or the germline of the offspring? What happens when a organism containing wild type allele mates with an organism containing the drive? If the copying is occurring in the Zygote stage, all somatic cells of the offspring will contain two copies of the altered gene and will be Homozygous recessive for the altered deleterious gene. Then how will the offspring be able to mate and SPREAD the drive before perishing (or not being able to reproduce). Or is the copying of the altered deleterious gene happening in the Germline of the offspring? How is it ensured that drive copying only occurs during gametogenesis and does not alter the somatic cells in either parent or offspring? Because if somatic cells were rendered homozygous drive would extinguish itself before being able to spread because in engineered gene drives the organism has to be homozygous with respect to the altered gene for it to have a deleterious effect....

    Gene drives, as they are described here, would work for plants that reproduce sexually through pollination. Some plants have a complex life cycle that includes pollination as well as spores; gene drive could indeed work in these plants. Plants that reproduce entirely asexually would pass each pass on their genetic information to their clonal offspring, but the modified gene would not be likely to spread because the unmodified plants would reproduce independently, not interacting with the modified plants. Considering generation time/life cycle and the ability to fertilize widely would be important.

    Fully agree Marc, the more efficient Gene Editing gets the more we must organize precaution. It is simply not done by comparing the ages-old EU- and Cartagena Regulations (which urgently needs enhancement(^) and declare that some gene editing methods fall out of the paragraphs and therefore they need not to be regulated, especially with the rather naive argument of naturalness of the new methods. Gene drive efficiency demands from researchers and regulators to intensify the public debate and also do a better job with risk assessment for food, feed and field. But this should not prevent us to be enthusiastic about the new elegance of breeding methods, it should encourage us to do a better job.
