How Gene Editing Is Curing Disease

[@C0smiChr1s]

I am one of the people that Crispr cured. I was cured at children's hospital of Philadelphia after 28 years of Sickle cell SS! I now have more energy than ever before, my eyes aren't tinted yellow anymore, I can go out in the cold and not sickle. I feel like they just gave me a whole new life honestly.

[@userou-ig1ze]

why

[@Pyriphlegeton]

Gene editing might just be the most needlessly feared and underused technology of today.

[@tomc.5704]

@Sandcastle • That's a bit of an exaggeration. There's only around 1.5 billion people born per decade, and the vast majority of them wouldn't benefit from our current capabilities. For that matter, we don't have the industry of scale to help everyone--even for clear-cut cases like the sickle cell treatment, it's way too complicated and expensive to provide to everyone who needs it.

[@aguven]

I work as a PhD in a gene editting lab using CRISPR technologies to study cancer. It is not needlessly feared. There are some things that we should resolve and be concerned before we use genome editting widely. The number of different types of proteins in body is estibated between 80.000 to 400.000. Basicly, we dont even know how many proteins there in the body. We know one function for maybe quarter of those proteins. The remaining 75% has unknown function. Add the fact that each protein can have several different functions and dozens of interactions with different proteins to for more complex structures to accomplish more complex tasks. We dont know in which type of cells, which of those 80 to 400k proteins are activated. We cant even make a good categorization of subtype of different cells. Thus, we can not even imagine the all consequences of each editing in molecular scale. Yet alone cell scale, tissue scale, organ scale, system scale, organism scale. Because we dont know enough about the rules of the cell yet. For example maybe the transcription factor they edited out is a currently unknown tumor suppressor. And editing that out will result in increased tumorigenesis in these edited cells. And that person will maybe develop cancer due to that editting. We currently dont know for sure, since we dont know enough about the cell yet. That is why genetic engineering has a lot of risks to be assessed before it is used worldwide. By the way there are also several other problems else than that. One last I can mention before it gets too long is the specificity of CRISPR. Yes it is very precise editing compared to older editting tools. Because guide RNA binds to DNA very precisly based on its sequence. Cas9 cuts at the precise location based on guide. However, in real life things doesn't work perfectly. Even if their sequences differ with 1 nucleotide, there is a small chance the guide RNA bind to off target locations with 1 or 2 mismatch. Which means it might binds to off target locations despite not being perfectly complementary to that location. Cas protein can cut at wrong location. Things doesnt work perfectly in cells. But when you apply a therapy to a person, you dont have the luxury of saying of there was a 5% chance of off target cutting and now you have increased chance of cancer. There are rules regulating what you can put into the medical market as a "therapy". I hope it would be explanatory :) Have a nice day

[@jerem101888]

@@aguven thanks for all that information. I learned a lot in reading what you said, in addition to the video.

[@Pyriphlegeton]

@@aguven - I agree that there are risks associated with gene therapy. My point however is that people fear it too much and for the wrong reasons. And not only when used in humans but especially in agriculture. People suddenly fear a plant when it's edited with CRISPR but will happily consume plants that have been heavily modified by chemicals and radiation over decades. Because somehow that's more "natural". - now to the specificity point. Studies in recent years on human embryos seem not to detect an appreciable rate of off-target effects. Modern tools for gRNA design greatly reduce the risk of them. A miniscule chance will still happen if we edit billions of cells however. But as a researcher on cancer you should be well aware that one random mutation is unlikely to produce cancer. So, in a child with a very well understood genetic disease (let's say Duchenne muscular dystrophy) it is very likely that we can simply cure his up to now uncurable disease with a miniscule chance of raising his risk for something else.

This is just flat-out scary. A grown woman is clearly not a fetus, she is therefore not supposed to have an abundance of "fetal hemoglobin cells". I cannot imagine that coaxing the body into creating hemoglobin cells that are intended for a fetus will not have drastic consequences at some point down the road.

[@cabo1656]

Yes, no one can be sure if somehow that fetal enzyme have some kind of disruption on the adult metabolism. But it should be highly unlikely, enzymes are extremely specific on their function, so it isn't often that enzymes mess with things it shouldn't(it happens, but is pretty rare). And because the fetal enzyme is something that the patient synthesis on their body, obviously it shouldn't produce rejection(yes, even as an adult). For diabetic people it was normal to get insulin from pigs, and though pigs are really close on physiology to humans, people still get rejection. Or how it already happened to humans at least once, the mutation that activates a gen that originally only happened on early childhood. Said gene synthesis the lactase, which is the enzime that let us digest lactose, so people who have ancestors with the mutation can have milk and people without that mutation on their genes are intolerant to lactose. I can understand that this comparison isn't clean because both aren't supposed to be active exatly on the same period. But on principle is the same, lactase shouldn't be produce by an adult, so the concerns should be the same on both(considering the time the lactase mutation first began), the lactase at the time had the same potential to be bad(not much).

This is a great introduction to this topic! And hooo boy, y'all just wait for what we can do in the future. Chemotherapy and a bone marrow transfer is cutting edge today, but will be seen a crude technique. Right now, we don't fully understand how the body works. We don't know what enzyme or signalling protein would grant us access into the cell to perform these edits directly. But we know a hundred times more than we did thirty years ago, and we have labs working on these questions, and we have labs learning how to create biological nano machines (i.e., proteins). I kid you not, we have a path towards curing every disease. Every. single. one. It's a long and difficult path, but we can finally see it. We probably won't get their in our lifetimes, but we will see progress. (And if we get quantum computers to a useful point, we will see a LOT of progress. The entire Rosetta@Home program would be trivialized by a quantum computer.)

[@Michael-op1lj]

Awesome episode, I love that CRISPR is actually translating to helping people in a clinical setting, which takes a lot of time in all of science from research or discovery to practical application(s), I have one small correction - gene therapy and genome editing at the level of somatic cells have existed long before widespread CRISPR-cas9 based protocols. Around 2011-2013 we got the nice CRISPR instruction manual paper(s) culminating in the ran et al., 2013 paper labs use for mammal applications of CRISPR. [1] I'm focusing on adult somatic cell mods here, which have been done in research using ZFN and TALENS, although CRISPR-based systems may promise greater specificity with less off-target effects, the main benefits IMO are the low cost and ease of access with easy programmability leading to potentially greater success rate with a low cost, i.e. widespread use and availability. It's like saying before 1960 no cars could travel at 140 mph, there were such cars, but now CRISPR can be had for a few 100 USD instead of thousands or more for a single test of gene therapy - overall treatment costs are obviously more than this, but just considering the reagents and cas proteins required. It's great that such a powerful tech is now available but I hope we can use it responsibly and recognize that CRISPR isn't a magical machine that eliminates all off-target effects. Any secondary off-target effects that hit other essential genes with a similar sequence should be thoroughly investigated for each given single gene disorder/single gene edit, and consider the effect of possibly removing code from one of the most interconnected and complex systems we know of (i.e. mammal/eukaryotic/human genome). However when used in bacteria, I am very comfortable using CRISPR because I'm not that concerned with the quality of life of my cell culture as long as they make my recombinant target and serve their purpose, but for humans even for a small and localized alteration like targeting a single gene in blood, liver tissue etc it could have profound consequences that could take a while to truly see even if your model is very sophisticated and has shown where possible aberrant cuts could be made; we can never be 100% sure what the effect(s) would be - all genes control other genes, some indirectly (like getting a cut activates the immune system, but the cut itself doesn't produce white blood cells), and many direct, like how about 1500 regulatory genes exist in humans to regulate the 20 000 or so other genes [2], so these controller genes (ie transcription factors, TFs), are used to activate a gene, and 20 some TFs must come together and regulate the activity of any single gene, so messing with one TF doesn't affect only one gene, it could a dozen genes, although there is some redundancy built in.

Yup! But there's so many layers of concerns associated with that, I'm still hesitant to advocate for it. Come to think of it, how exactly would we test and treat the fetus? We'd need to get the fetus' genetic information....how exactly would we do that without harming the fetus? We'd also need to perform the editing early, or all the challenges associated with using gene editing on an adult come into play. Which also means we'd need to notice the pregnancy early so that testing could be performed... But also if we perform the treatment early, we'd have to be 100% sure that we wouldn't damage a single cell... It would be much easier if it was an in vitro pregnancy, but I don't believe those are common (or cheap), and I'd hate to see genetic editing be something that only the rich have access to.

The only thing wrong here is that they make Sickle cell out to be life threating for everyone who has it. However, you can be a heterozygote for the disease and it helps act as a resistance to malaria in Africa. There is a very interesting map that shows where a "line" of heterozygotes live across the continent and where malaria almost stops.

I see potential of this technique in baldness therapy.

[@varaddharap7899]

@Fareed Waseem excellent analysis. Best luck to you 👍🏻

[@tonyggir]

Man. That is complicated stuff. Amazing they can figure it out

[@itsrachelfish]

WOW!! This is amazing content. 10:23 the computer chip from Lain is real.....

[@chrilin5107]

Great episode, have only exploded epigentics a little but now I'm definitely motivated 😊

[@KhanjanYT]

Im actually a Biotechnology Grad and this CRISPR technology is so powerful that I fear it will be weaponized just like every other great human inventions.

[@skrame01]

Awesome article thanks.

By watching this video, I'm feeling that we are more like computer application program and our source code is encrypted into our DNA... And this technology is undescribable...

Hi im a muslim

[@estevaodealmeidasilveira3822]

this is the power of knowledge

_"CRISPR system requires stable expression of Cas9 in the cells. However, prolonged expression of Cas9 in living cells may lead to chromosomal defects"_ _"In immune-incompetent hosts, allogeneic cells are able to engraft, but their endogenous T-cell receptors (TCR) specificities recognize the host tissue as foreign, resulting in graft versus host disease (GvHD), which can lead to serious tissue damage and death."_

CRISPR-Cas system is my love it's change my professional career

[@lucasgoye88]

There is a whole documentary about CRISPR called "Human Nature" from last year. It's incredible really, it can be a great such a tool or weapon; and China is already making more progress in both ways.

[@pegprentice1286]

I loved this video & its excellent explanation and plan to use it for my Biotechnology class. But, I do have one small but important suggestion. In the future when referring to “researchers”, could you please make it a point to show some women. We are in the lab, working hard, and would love some representation. I’m sure that Drs. Charpentier and Doudna would agree!

[@ahmedahm1]

CRISPR in Beta Thalassemia !!! I hope it works in all rare diseases and enables people to do more & feel better

[@aprilmingone3271]

is that what you have thats what i have!

[@Maulstrum97]

genetic editing is only being held back by scientific ethics. the injection of philosophy into science has slowed scientific progress in many fields. computer aided crispr editing would be a medical revolution and a large step in human longevity. the best step in understanding the genetic sequences of the human species and it's many subspecies is to make a centralized medical database with full genome sequencing on all medical patients. that database can be used to analyze the common genes of those with disorders and allow us to isolate the disease causing genes for study.

[@varelmarais2222]

Science without ethics doesn't sound like a good thing to me 🤔

[@maishaadams7324]

This is wonderful news…My son has been battling sickle cell for 32 years and now has multi organ damage due to it. He has a defibrillator and at stage 4 kidney failure😔. I wonder if this could help him or at least give him a few more years with me😢
