Disease-Resistant Pigs Latest Win For Gene Editing Technology (reuters.com) 125

schwit1 writes with news that using gene editing technology researchers have bred pigs that do not produce a protein necessary for the Porcine Reproductive and Respiratory Syndrome (PRRS) virus to spread. According to Reuters: "A British animal genetics firm, working with U.S. scientists, has bred the world's first pigs resistant to a common viral disease, using the hot new technology of gene editing. Genus, which supplies pig and bull semen to farmers worldwide, said on Tuesday it had worked with the University of Missouri to develop pigs resistant to Porcine Reproductive and Respiratory Syndrome Virus (PRRSv). The condition, also known as blue-ear disease, can be fatal as it affects the animals' immune system and costs farmers hundreds of millions of dollars a year. There is no cure. By using precise gene editing, the team from the University of Missouri was able to breed pigs that do not produce a specific protein necessary for the virus to spread in the animals. Their research was published in journal Nature Biotechnology."

        I'm not a fan of editing individual genes.  In OOP, classes have private members that are accessed through get & set routines.  Any programmer knows that you don't hack your way into an instance and modify a private member outside of its set routine.  Sure most of time thing.setx(y) is just thing.x=y, but when it's not, all hell can break loose downstream and you might not know why.  We understand this for computing, why do we not understand this for life?

Not much point to it if it doesn't sell but they still continue on with the research. Something like this may not show an error for generations and no one wants to discover that down the road after the genome has cross pollinated and/or produced offspring and self destructed the species or worse yet the species that ate it.

          This isn't programming. This is editing a save file.

          Find a save file with tetrachromacy. Run a diff between that and a normal save file. Delete the unwanted overlap. Insert the tetrachromacy code. You "should" end up with a genetic identical to the start save file, aside from tetrachromacy.

          Repeat with whatever previously identified traits you want, and you build a super-save-file.

          You can also do the reverse. Identify a disease sequence. Identify the associated sequence from a healthy save file. R

      I think that's a valid concern. They say this:

      By using precise gene editing, the team from the University of Missouri was able to breed pigs that do not produce a specific protein necessary for the virus to spread in the animals.

      But what's the purpose of that protein in the animal? Surely the only purpose of that protein is not to allow the virus to spread, or else you think that would have a habit of being selected out of the lineage. Surely it has some beneficial purpose that has ensured it stays part of the animal. It seems a little too easy to remove disease by just deleting the part of the animal that the disease uses.

      • 8 minutes, give or take a few seconds. Thanks.

        If the pigs don't survive better without the protein, then the improvement will fail in the marketplace. The evaluation of "better" includes balancing the lifespan of the pigs against the death rate of the pigs and the disease. Given that a pig intended for food doesn't need a huge lifespan to begin with, the result will be biased to "fewer dead from disease".

                And what I was getting at was that were this specific protein important enough to the life of the pig, then the modified pigs will not survive the market. Farmers aren't going to try raising pigs that won't live long enough to make it to the butcher. They won't buy the modified pigs, and this will become an interesting footnote in the history of gene editing.

                But once again, it doesn't matter what the pig thinks about it. You care more about the pigs than the people who eat them, I get it. But the standard argument against GMO is not what it does to the O, it's what effect that O has on the people who eat it.

                We have a very very long history of people who eat NO pork. Thus we can be sure that pork that doesn't have a specific protein will NOT have any negative effects on people who eat it, because there are no significant negative effects on all the people who already don't eat it.

            CD163 is a relatively well described protein with very detailed functions, mostly on innate immunity. Fortunately innate immunity have many kinds pathways that interconnect and supplement each other (probably because pathogens are very good at interfering with them) so blocking one pathway at the beginning, like in this case, would have very little effect overall and interleukin 6 and 10 (and the rest of the cascade) will be still produced. For the virus of course this lack of CD163 its lethal, but for the pig it may at much represent slightly increased rates of infections of other pathogens, many of those are no longer important since the pigs are not in the wild anymore.

              The left want the science of the telescope to go ahead. It's the conservative loonitarians who think eminent domain shouldn't be used against private land owners.

              You should have used "liberal" The definition has been reduced to "anyone I don't like", with no regards to politics or anything else.
              • Eminent domain is not a factor in the TMT controversy. The TMT was supposed to be built in a public reserve area administered by University of Hawaii, specifically for astronomy.

          • What do you know anout what people are arguing?

            Ummm, because I read their arguments. I know what the standard arguments against GMO are because they come up every time some new GMO issue comes up.

            99% od the anti GMO front only want two things: a) don't let get GMOs go wild b) lable food that contains GMOs

            So you are completely ignorant of the arguments they make in support of those demands. Why does food made with GMO need labels? It's not because they worry about how great the GMO products will be for them, it's because they think they will be harmed by them and don't want to eat them.

            For some strange readon the GMO Mafias pull every string availbale to prevent those two things becoming law.

            There is no law against labeling products that either do or do not contain

            • There is no law against labeling products that either do or do not contain GMO components. You don't need a law to do it.
              Ofc you need a law.
              Or how to get labes on the GMO food?
              If people don't wan't to eat it, but have no chance to figure which produces contain GMO food, you obviously need a law.
              That is a no brainer. If there wasn't an pro GMO MAFIA lobbying your law makers, you had laws demanding labels since 25 years.

              But good luck with your anti social attitude. Why do you care what other people want if it

                No, you do NOT need a law. There are labels RIGHT NOW, with no law, that explicitly state either non GMO or Organic. Use your brain for a change and make the giant leap that everything NOT so labeled is GMO. Is that really so hard?

                Again, the push for labels is NOT so people who want to eat only non GMO foods can do that (they can already do that if they are capable of thought), it is to spread FUD. The anti GMO nuts think if they get the labeling it will scare everyone off of GMO (why would they have to

                • I doubt that all non GMO Food is labeld "non GMO".

                  , it is to spread FUD. The anti GMO nuts think if they get the labeling it will scare everyone off of GMO

                  You are thinking that not they. Big difference.

                  And Europe spends TWICE as much on food as a percentage of income than the US does.
                  Yes, because we like qualitiy food. Or because the average income is lower :D You see, comparing averages with averages makes no sense. But keep ranting.

                  And THAT is the reason

                  • by bws111 ( 1216812 )

                    So what if not all non-GMO food is labeled? Nothing is stopping the manufacturers from labeling it as such. If enough people cared about non-GMO then there would be a significant economic benefit to labeling.

                    Are you seriously suggesting the US should change its labeling laws to please FORIEGN anti-GMO nuts? No thanks.

                    I would back off my claims of FUD if one of the antis would ever give a reason that did not involve FUD. Every one of their reasons is some sort of restatement of 'They could be dangerous,

              • If people don't want to eat it, they can buy the stuff that's labeled "GMO free". If they want to eat it, they can buy something that's labeled as containing GMOs. If they don't care, then they'll buy something with a label one way or the other, or no label. If enough people don't want to eat GMOs, then companies will - and do - make products that don't contain them, and market them as such.
                • If enough people don't want to eat GMOs, then companies will - and do - make products that don't contain them, and market them as such.
                  This is obviously not true, as 90% -- depending on country -- of the populace don't want GMO food. Companies don't care as long as they make a profit. Especially in the USA.

                    In the US, there are tons of products that say "GMO free" on them. Some people buy them for various reasons, most of which I disagree with, but they're perfectly within their rights to do so. Plenty of other people don't care one way or the other, and don't look for the label.

          Well, to start with we couldn't really find the gene that made the protein so we took a handful of genes from another animal that didn't have the protein and just threw them in the pot at random until we got a pig that didn't have the protein and survived for more than a few seconds out of the womb.

          As a side effect, female pigs will now have to be slaughtered by extremely well trained butchers under precise conditions, since if the ovaries are nicked they will flood the rest of the body with a deadly neurot [wikipedia.org]

        " Surely it has some beneficial purpose that has ensured it stays part of the animal."

        Yeah... same as your appendix, wisdom teeth, coccyx, body hair, among other parts of YOUR body . You MUST have them. They're CRUCIAL to your survival.

      • It seems a little too easy to remove disease by just deleting the part of the animal that the disease uses.

        It depends on the path the disease is using. Think about blood type receptors and immune system response. IE this technique will probably work great on some diseases, and not at all on others.

      • you think that would have a habit of being selected out of the lineage.
        Why should it?
        As long as the animal can breed before it dies, thare is hardly any selective pressure.

      • Humans with a deletion in CXCR5 are resistant to HIV infection. Their immune systems don't work *quite* as well in a few situations - parasitic infections, if I recall correctly - but mostly, they're fine.

        Some genes encode receptors that are mostly redundant - other pathways can compensate for them if they're gone. I haven't looked at what they deleted, but my guess is it's one of those receptors. Will the pigs be as healthy as their counterparts without gene editing? I don't know, but my guess is that th

      I find this and all the hoopla about GMO's pretty entertaining. On one hand we are worried sick that GMO that produces extra things will kill us and in this case we are worried that something being missing will do the same.

      All this fear is unfounded if you consider how protein is actually metabolized. What really matters is that the protein gets decomposed by your digestive tract into individual amino acids. So unless there is some kind of amino acid not in the provided protein, it doesn't really matter

      • I find this and all the hoopla about GMO's pretty entertaining. On one hand we are worried sick that GMO that produces extra things will kill us and in this case we are worried that something being missing will do the same.

        Fear of the unknown, and refusal to learn. All of these differences in gene expression can and do happen through normal reproduction. Lack of this protein is probably what infers a "natural" immunity in the first place. I'm not certain what the denialists think confers immunity.

        tl;dr version. If a person doesn't like this sort of thing, only eat pigs that died of PRRS. Oh - and figure out some way to prevent genetic variability.

      • So we can just synthesize that protein in a lab and add it back to the meat during the curing stage. Everybody is happy.

      Well.. Get your flu shot sicko, it works for me.... I haven't had a serious case of the flu for about 5 years and I figure it's because I get the shot every year for medical reasons (a member of my immediate family takes immune suppressants).

        but, they don't always work. two years in the last five they were against wrong strains

      • I never had the flu, and I never had a flu shot.
        I figure it is because I live healthy and had luck in avoiding places/situations where people with the flu hang out to long.
        Perhaps you should fugure how a flu shot works?
        As long as you are mot an elderly or in an high risk environment (or a pandemic is brooming on the horizon), flu shots are pretty pointless.
        It is like running a virus scanner on a PC without internet connection, no CD, Floppy and USB drive.

        • Oh I understand how they work, but I do them for reasons other than keeping myself from getting sick, though that's a side affect. Studies have shown that even flu shots which are not properly targeted, do usually help to lower the severity of the sickness and help it to not last as long, reducing the chances of transmitting the virus to others. I get the shot in the hope I will be less likely to carry home the flu and pass it on to the member of my family who would have their life put at risk if they get

              Eventually your Mac will acquire a virus, you should be ready to find and deal with it. Right now you are relatively safe because Mac's are a fairly small market share and has a very tightly controlled ecosystem, and you have good hygiene habits apparently (like washi

        • First, our species is social so avoiding places with people (people with the flu go everywhere) is impractical and you can get the flu from things touched by people (have you ever ordered something off the internet?) without ever actually meeting people. Second, you've either been incredibly lucky to have never contracted influenza, or you live in denial. Third, waiting for a pandemic before getting a vaccination won't work because there won't be enough vaccine available on short notice (companies won't sto

    Maybe the pigs wouldn't be getting the diseases in the first place if they weren't kept cheek-by-jowl in their own filth, in pens where they can't even turn around.

    But have no fear, now that there are laws against taking pictures of factory pig farms and the horrific conditions the animals are kept in even from public property, we're all going to be more safe because of genetic engineering.

      You realize that pigs are rather cruel mean and violent creatures? try talking to folks that work on pig farms, in the good old days before "industrial" farming one of the daily chores was to count the pigs in each open pen. The reason you had to count was because the pigs would constantly nip and bite each other if they sensed any weakness, and if they ever broke skin they could and would eat an entire pig in a day. A large part of the 'cruel' conditions pigs are kept in today revolve around things like ke
