I spoke about gene therapy once to a relative and he used the usual words like, "unnatural," "playing God," and so on. I asked him, "if a doctor saves someone's life, do you believe he has played God by keeping one away from the afterlife? Couldn't advances in science and medicine actually be answers to prayers?"
Ask them if they've ever taken or known anyone who has taken antibiotics, or had surgery. Both unnatural, both extend life. In the past those people would likely have died from an infectious disease, died without surgery, or at the least been left severely weakened or crippled without intervention.
having a simply healthy child...living a normal..healthy life...is not the same as ''designing super children''....plus we are nowhere close to advancments like that,simply cause its not a priority at the given moment, but it already is set into the future prospects, and we cant really change that. nothing new.
those who thinks gene therapy is unnatural should first judge their mental capabilities. your God should be the one to stop doctors if he/she/it if ever exist. if you have capacity to leaf frog what nature have done for millions of years into just few days, it would be foolish of you not to take the opportunity. to hell with unethical or playing God. genetic diseases are random occurring things. one thing I do know is the life forms on earth including us are controlled by natural event. it is right for humans to reinvent themselves. Religious people should shut up and accept their stupidity.
Miks, if one has capacity to create super human beings, then he/she has right to do. we should not leave lives to mercy of nature. remember what happened to dinosaurs could also happened to humans. dinosaurs did not choose to die from asteroid impact but due to lack of brains to deflect the asteroid coupled with bad luck sealed their fate.

@@bryanleggo3489 True, but Transfer RNA (tRNA) simply serves as a link (or adaptor) between the Messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein. Each time an amino acid is added to the chain, a specific tRNA pairs with its complementary sequence on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein being synthesized. In both the case here, and with the mRNA Vax, the goal is to get the cell to produce Proteins, be they Spike Proteins or otherwise.
Would love to see this therapy utilized for PKD/ARPKD. Keep doing amazing work! Also, it's not hemaglobin,...it's hemoglobin. It was spelled wrong on your slide presentation. Wish I could get a chance to be part of a biotech company like this. We are on the cusp of incredible treatment options.
This mostly opens the way for editing embryonic cells. For adults the problem would be about reaching cells inside the body. Of course everybody is speaking about blood stem cells, or sickle-cell disease, which are easily accessible to CRISPR/Cas-9 genome editing, as the targeted cells are in the blood. Just inject the solution, with some trans-membrane factor... but how do you access cells that are disseminated deep inside tissues, far from blood vessels ?

I am for stem cell research and gene therapy. However, those types of neurodegenerative diseases are new on planet Earth. Those illnesses are standing in direct correlation to the rise of environmental toxicity caused by pollution. Also eating meat, and in particular the meat of today which has been made toxic through hormone treatments, pollution, and vegan animals eating meat pellets in a perpetual cycle of rendering plant meat getting into the systems of vegan animals.
If you go through with it, I strongly suggest looking into cosmetic gene therapy. Fewer people are born with rare genetic ailments than people discontent with aspects of their appearance. Namely hair texture, baldness, or skin/eye color. If you want a career that pays the bills, that's a future job waiting to be filled. Cheers.
they make it sound so simple but forget all the other probable problems from putting foreign entities into the human body and the way the body will react thereafter in the short term and long term..he also said not all survive this gene therapy
We have several gene therapies on the market. Bluebird has since gotten four drugs approved that are now on the market. The drug for ALD described here is expected to be approved in Europe in 2021 and in the US probably 2022-23.
The ones who are suffering from genetic diseases should answer the questions, not the healthy ones who come up just about any excuse to be self righteous. Children have suffered enough from genetic disorders / diseases and its about time all of us should help put an end to it.

Gene therapy shows a very interesting twist in the modern ethical dilemma, and it does not seem to have a clear solution as to its remedy. I think this method of treatment is lacking in research funding and its potential is underestimated. We could potentially eliminate some genetic issues with simple mutations, especially deletion mutations, such as cystic fibrosis. There are many issues that face gene therapy, but it is possible with more research and time that we achieve effective therapy in humans or embryos. However, this video touches on yet another ethical dilemma. Will the cost of gene therapy be too high? What parent wouldn’t pay everything they had to save their child from a horrible life? Will only the children of the wealthy be allowed to cured from these diseases? Will only first world countries have this privilege? However, this argument could also have been used to stop the human genome project, but over time gene sequencing has improved to such a degree that it is cheap and available to everyone. Could this not also be the case for gene therapy?
wait....did he just make the DNA chain longer? would the injected cell really proliferate like that...I thought the number you stay relatively constant, cells cant just divide whenever.

we are! For X-linked retinitis pigmentosa we have several gene therapy companies working through treatments! The most promising late stage one is probably Biogen's, which is about to finish their Phase 3 and likely enter the market in a year or two with good data. The most promising earlier stage ones are from AGTC and MeiraGTx.
***** I am not sure of your explain. There are 2 concerns, the cells and the artificial proteins. 1 Some GMO food can lead to allergy while the corresponding natural food do not cause any allergy. 2 The artificial proteins are allien to the host. If these proteins, not seen by the host before, trigger the immune system in the host, they will probably trigger the immune responses, because the therapeutic gene products are considered as intruders.
If funding and ROI is such an issue, they should just work on cosmetic gene therapy to foot the bill. As an example, there are literally millions of African women (men?) that want manageable natural hair. Rest assured they'd be more than willing to pay thousands for a procedure that safely and permanently changes the shape of their hair follicles, so as to achieve a looser curl pattern. The same could also be said for those looking to change eye or skin color - traits of which I'd think are relatively easy to alter. It may seem an outlandish idea, but I think researchers can acquire a lot of the much needed capital with cosmetic manipulation. In doing so, we could at least exploit the inherent insecurities of humanity to not only make a better world for those with life-threatening genetic ailments, but to make people more comfortable in their own skin.
Strauss Field Yes, I would imagine it'd be relatively easy to alter pigmentation. It's just a matter of corporate support for an untapped market. I suspect the only thing getting in the way of these advancements are traditional views on ethics.

Someone way more advanced than us must have designed everything. Even trying to copy DNA for programming makes programming advance by 100 years. Reminds me of reverse engineering alien technology but instead of a Roswell crash we are all walking around in our own personal UFO.
I have a question, and I would appreciate anyone with relevant knowledge to answer. So how does gene addition or gene editing actually work? Wouldn't our body recognize the changes to the DNA as a 'mutation' and try to fix the change (since there are still other copies of the gene in 23 pairs of chromosomes). And even if we got it to work, how do we apply the treatment to every individual cells in our body? I am really confused. Plz some one help me!
It's been over a year but someone else who ends up on this comment might benefit from an answer. In the video they showed an integrating virus (modified from HIV) so it is just added permanently to your own DNA (DNA is DNA there is no yours or mine it's a chemical). To answer your question, how is it not recognised as foreign? Well immune response cells recognize other cells by their surface. The surface in this case was the patient's own stem cells that were previously harvested. At the DNA level, for example when a virus enters the cell and releases its RNA or DNA the cell has some defense mechanisms in the form of enzymes to degrade them called DNases and RNases. Unfortunately, there are no DNases and RNases in the nucleus so once it reaches and enters the nucleus it can use DNA polymerase to multiply therefore more of it will be made, while it is continually destroyed outside the nucleus by DNases and RNases. For your question about targetting specific cells instead of every one, we usually add a tissue-specific promoter. This means for example this new gene will only be active in the heart and nowhere else. However, sometimes it doesn't matter and you just express it everywhere and it works fine just like in the very recent Zolgensma drug for SMA. These are some of the reasons gene therapy research is slow: delivery, efficiency and keeping toxicity low. Much like the video said, some of the cells were made into macrophages and only a proportion of that managed to enter the blood-brain-barrier. In practice it's much harder than it sounds to just put the gene, it usually never reaches its destination and is just destroyed by the liver, never enters the cell, if it does it's usually degraded and if it's not it's usually not enough to show significant effect on the patient.
Is the pharmacutical business willing to allow a treatment that will cure, thus the need for thier bandaid solutions will no longer be needed, and their business will cease to exist.
