[DIYbio] Re: "DIY Human CRISPR" by Josiah Zayner


Hi, so I'm new to google groups so I apologize if I'm replying to the wrong post in this thread. I figured it was better than starting a new one.


I have three interests in CRISPR;


1: Deleting my Y chromosome and inducing other edits in a variety of genes such as ADAMTS9, HOXC10, FTO and LRP5 and others to adjust my fat distribution and body shape (I'm transgender;)


>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5701507/

>Elimination of the Y chromosome in vitro and in vivo

>Together, these results indicate that the Y chromosome could be selectively eliminated in vitro and in vivo by CRISPR/Cas9-mediated multiple cuts at chromosome-specific repeated sequences


2: Knocking out my MC1R gene to induce red hair,


3: Knocking out my OCA2 or HERC2 gene to induce blue eyes.


I'm not sure deleting the Y chromosome would actually have any meaningful effect - but knocking in or knocking out various other genes might have an effect on WHR. This could be very beneficial for a transgender person 'passing' as the opposite sex. Considering that Gender Identity Dysorder is a formal diasnosis, and that cosmetic surgery is considered ethically justified in the case of gender transition, how could CRISPR be denied to a transgender seeking genetic 'bodyscupting?' Objectively, good results with traditional fat transfer are hard to achieve, and implants are illegal in the USA (I think.)


The entire ethical justification against cosmetic CRISPR falls apart once you've allowed transgender use of the technology. Why let a transgender delete their Y chromosome, but cis-gendered people (Or transgenders) can't modify their eye or hair color?


In this Geneva statement, as many have already noticed, there's a sentence I find frightening;


'Prospective parents at risk of transmitting a genetic condition already have several options to avoid doing so, should they find them acceptable. For example, prospective parents may seek to have unaffected children via third-party gametes or adoption'


Because as a transgender, if I continue HRT, I'll likely need advanced reproductive technologies if I want biological children. Also, this following sentence seems to contradict the value of third party gametes and adoption;


>In nearly every case, prospective parents at risk of transmitting a genetic condition who wish to avoid doing so and to have genetically related children can accomplish this with the existing embryo screening technique preimplantation genetic diagnosis (PGD) [5]. While PGD also raises troubling ethical questions about what kind of lives we welcome into the world


PGD can and is used to select phenotype. Most white people with brown eyes carry one copy of the blue eye allele - any two whites and many mixed people such as African Americans could obtain a child with blue eyes via PGD.


The legal opposition to PGD in many countries across the planet, and the social opposition in places like the USA reveals why germ line editing is opposed;


'Racism and xenophobia are resurgent around the world'


Which apparently means I can't use CRISPR to give myself blue eyes.


I hate to admit it, but it feels like the anti-CRISPR side has won the debate. It's impossible to get a hold of the Cas9 enzyme or the gRNA unless you're an academic. And the people who have access to it will never use it for anything other than 'genetic diseases.' And albinism seems to be one of those diseases, and my desire to knock out OCA2 and become an albino is probably considered insane. Immortality will probably never happen.


Metaphorically, the pro-CRISPR and anti-CRISPR groups broke a wishbone, and the pro-CRISPR group was on the losing end. And it hurts. It hurts so bad to have been told 'No.' To be forced to continue to live in skin which doesn't feel like your own when a solution exists;

>Those who undergo gender reassignment surgery and hormone treatments do not get a sex change. A male to female surgery today will not produce a full biological woman when it is done. A person will likewise not be a full biological man if changing from female to male. This can be very disappointing in a life filled with broken dreams, and people who get surgery can find that their field of potential partners has not expanded, it has narrowed


All I can do is beg other human beings - my supposed equals - for the right to change myself with CRISPR. I'm posting here out of a hope that people will be convinced to allow me and others to modify their Sex Chromosomes and pigmentation.

Geneva Statement on Heritable Human Genome Editing: The Need for Course Correction


Trends in Biotechnology SCIENCE & SOCIETY| VOLUME 38, ISSUE 4, P351-354, APRIL 01, 2020
 Published:January 31, 2020 DOI:https://doi.org/10.1016/j.tibtech.2019.12.022

...
Heritable Human Genome Editing: Nearing a Critical Juncture

"We contest moves toward reproductive use of human genome modification and affirm the need for broad societal consensus before any decision about whether to proceed is made. We insist on the need for genuine public engagement that is inclusive, global, transparent, informed, open in scope, supported by resources, and given adequate time.
Toward that end, we call for an urgently needed course correction (Box 2) along three dimensions.

First, we need to address and clarify several misrepresentations that have distorted public understanding of heritable human genome modification.
Second, we must reorient the conversation by foregrounding societal consequences and undertaking a thorough analysis of threats to equality.
Third, we need criteria for 'public empowerment': robust public engagement that promotes democratic governance through shared decision-making [4].


Perhaps the most fundamental and widespread misrepresentation is that heritable human genome editing is needed to treat or prevent serious genetic diseases. Deliberations about heritable human genome editing should hence acknowledge these basic points:
• Heritable human genome editing would not treat, cure, or prevent disease in any existing person. Instead, it would modify the genes of future children and generations through the intentional creation of embryos with altered genomes. This fact makes it categorically distinct from somatic gene therapies. Heritable human genome editing should be understood not as a medical intervention, but as a way to satisfy parental desires for genetically related children or for children with specific genetic traits.
• Modifying genes in early embryos, gametes, or gamete precursor cells could produce unanticipated biological effects in resulting children and in their offspring, creating harm rather than preventing it. Heritable human genome editing would also require and normalize the use of in vitro fertilization (IVF), exposing healthy women to significant health burdens [4].
• Prospective parents at risk of transmitting a genetic condition already have several options to avoid doing so, should they find them acceptable. For example, prospective parents may seek to have unaffected children via third-party gametes or adoption.
• In nearly every case, prospective parents at risk of transmitting a genetic condition who wish to avoid doing so and to have genetically related children can accomplish this with the existing embryo screening technique preimplantation genetic diagnosis (PGD) [5]. While PGD also raises troubling ethical questions about what kind of lives we welcome into the world, modifying or introducing traits through genome editing would vastly intensify these concerns. Genome editing cannot be considered an alternative to PGD, because PGD would remain a necessary step in any embryo editing procedure.
Deliberations about heritable human genome modification must seriously investigate the implications of social and historical dynamics such as these:
• Competitive pressures to 'get ahead', coupled with commercial incentives in the fertility industry (especially where it operates in the private sector), could foster the adoption of heritable human genome editing by those able to afford it. Unequal access to perceived genetic 'upgrades' could then exacerbate the recent dramatic rise in socioeconomic inequality.
• Racism and xenophobia are resurgent around the world, fueled by discredited scientific and popular assumptions about biological differences among racially categorized populations. Eugenic thinking, which aims to 'improve' humanity through genetic and reproductive technologies and practices, persists in popular discourse and could be reinvigorated by the availability of heritable human genome editingiv [6,7]. These pernicious ideas increase stigma and discrimination against those considered genetically disadvantaged, including disabled people and communities, and undermine the fundamental equality of all people.
• Outcomes in related biotechnological spheres provide examples of the likely trajectory of heritable human genome editing if commercialized. These include the promotion of social sex selection by fertility clinics and of unproven and risky 'treatments' by commercial stem cell clinics.

Public engagement and empowerment are likely to reveal additional concerns that have not yet surfaced, particularly if we commit to including and listening to a broad range of voices and perspectives.

Chinese Scientist Who Genetically Edited Babies Gets 3 Years in Prison
He Jiankui's work was also carried out on a third infant, according to China's state media, in a new disclosure that is likely to add to the global uproar over such experiments.


BEIJING — A court in China on Monday sentenced He Jiankui, the researcher who shocked the global scientific community when he claimed that he had created the world's first genetically edited babies, to three years in prison for carrying out "illegal medical practices."

On Monday, China's state media said his work had resulted in a third genetically edited baby, who had been previously undisclosed.

Dr. He pleaded guilty and was also fined $430,000, according to Xinhua. In a brief trial, the court also handed down prison sentences to two other scientists who it said had "conspired" with him: Zhang Renli, who was sentenced to two years in prison, and Qin Jinzhou, who got a suspended sentence of one and a half years.

The court held that the defendants, "in the pursuit of fame and profit, deliberately violated the relevant national regulations on scientific and medical research and crossed the bottom line on scientific and medical ethics," Xinhua said.

American scientists who knew of Dr. He's plans are now under scrutiny. Dr. He's former academic adviser, Stephen Quake, a star Stanford bioengineer and inventor, is facing a Stanford investigation into his interaction with his former student. Rice University has been investigating Michael Deem, Dr. He's Ph.D. adviser, because of allegations that he was actively involved in the project.

Dr. Quake has said he had nothing to do with Dr. He's work. Mr. Deem has said he was present for parts of Dr. He's research but his lawyers have denied that he was actively involved.

Re: [DIYbio] Protein trigger in TALEN, ZFN, ...

That's a good question. I believe part of the answer is just the ratio of time the protein is bound to the target sequence vs near other regions of DNA. If >99% of the time the protein is bound to the target sequence and less than 1% of the time it's not, then at least 99% of the cutting or base-editing will be on-target. I'm not sure what the dwell time or kon/koff rates are for these proteins, but that might allow you to figure out how much of the time it's bound to the target. Interestingly, similar approaches with transposases haven't really worked. Fusing transposases to TALE domains, zinc-fingers, or Cas9 gives a little enriched transposition at the target, but mostly the transposase still integrates transposons all over the genome. Here's one study that did this: https://elifesciences.org/articles/53868

I assume there is a conformational change that activates the nuclease domain. But how do you design this?

Any insight would be greatly appreciated!

You're trying to add something to your immune systems blacklist.

The Pandemrix Influenza vaccine caused permanent narcolepsy in some patients because it targeted a receptor very similar to a receptor on the surface of certain types of neurons which the patient's immune system then wiped out.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5253292/

Assuming that it's safe just because the precursors are safe is about as wise as assuming that since hydrogen carbon and nitrogen are safe then hydrogen cyanide should be fine.

You could leave yourself with your own immune system eating away chunks of your brain.

Mainstream vaccine researchers specialising in the area are going to be much more aware of what to be careful of.

Thanks for this elaborate answer!! 

As far as I know, antibody-mediated enhancement should probably come with B-cell but not T-cell response. 

I know that a lot of vaccine makers are using the Spike protein, which apparently has a domain that looks like healthy lung protein domain, which then causes the immune system to freak out and keep attacking healthy tissue. Smart people have told me, though, that that probably wouldn't matter in a vaccine because the body would clear autoreactive cells. 

Chitosan being variable is a great point - one should look to get the highest grade of course. And all from the same source... 

I'm not entirely keen on trying it, but been contemplating. I signed up for a Corona vaccine trial (MVA based, so pretty promising in my opinion) in Germany but they said I live too far away. But my country is stone-age. I am 100% certain I won't get a chance before the second wave hits and it gets bad. And with the current level of stupidity... People either don't think that Corona is real, or that it's no worse than the flu (27% of the people in a survey), people wearing masks below their noses.

My take is usually the conservative one. :)

I don't think DIY medical bioscience is a viable or responsible route except in cases where no more professional approach is being done, or is available. So, whatever if you live somewhere with zero medical infrastructure or zero access to medicine, you do what you've gotta do. But people living where viable alternatives exist...

I also think that in this case, there's a difference between 'just peptides' and 'just peptides and adjuvents'. The nature of Adjuvents is that they make the immune system react more strongly (or extremely!) than usual to an antigen. That's often necessary when the antigen-dose of a vaccine might otherwise fade into the daily background hum of new antigens and fail to elicit a strong enough reaction. But it does mean that the immunogenicity of those peptides matters a _lot_ more than it usually would.

In other words, if there is some risk X of an immune overreaction to a peptide, and you add an adjuvent with some "adjuvent factor" Y, then your risk is now X * Y. Chitosan is probably not the strongest adjuvent out there , for sure. However, the strength of the reaction from the Chitosan is also probably _highly variable_ according to the grade of chitosan, the batch used, conditions of packaging and storage, and delivery method, volume, etcetera. Even the technique of the person doing the snorting probably matters, as it will affect where exactly the antigenic snuff ends up: upper nasal tract vs. deep lunch tissue!

And, I've worked in professional grade biomed research labs, and they're full of real humans with varying depths of knowledge and experience and risk appetite and fastidiousness. Deeply imperfect and 'doing their best'. And that's the gold standard you're trying to reach from a DIY setting: for all the good intentions in the world I think it's going to fall far short.

Finally, COVID has several methods of inducing severe reactions and lethal outcomes, and some of them relate to an immune overreaction, or an inappropriate immune response. I don't know how vaccine developers account for this stuff, or even if they do. But I could imagine a badly designed vaccine making this even worse: if by some (small) chance your vaccine _does_ elicit a reaction, it might end up being one that does much more harm than good. Say your body picks up on some epitope that usually occurs within the virus (and so the antibodies don't really affect real viruses), but when your body sees that exposed on an MHC complex it goes ballistic and triggers a cytokine storm: bad outcome.

Anyways that's my hot-take: it's not a risk I'd take, even for covid, while so little is known and so many better-prepared groups are working on better-considered vaccines.

Has anyone looked deeper into RADVAC? 

Basically they are working on a simple homebrew corona vaccine, by having peptides synthesized and mixing them with chitosan. 

The idea is that chitosan forms nanoparticles and takes up the peptides. Chitosan also acts as an adjuvant and stimulated both Th1 and Th2 response. 

The people there are already trying it on themselves and even George Church snorted it (not that that neccessarily means anything). 

The approch claims that it only uses materials and methods that have a long history of safe use.

Honestly, after the reports of long-term organ damage from Corona that doesn't look so crazy anymore? :D Worst case you snort some chitosan that gets degraded and some peptides that get turned into amino acids? Of course, I don't want to downplay the risks here. 

I just wonder what quality parameters you need. TFA content <1%? Quality parameter for peptides to not include truncated peptides or pepties missing amino acids?

Re: [DIYbio] Re: first, cheap and effective termal cycler PCR at home

DNases and RNases are notoriously tough enzymes. :)
But, I think people worry more about these than they should, too. If you use deionised water, then hopefully there are not enough ions around to 'feed' the enzymes before the reaction is prepared and ready to go. Just remember to keep the tubes chilled/on ice before and after the reaction, and consider adding a _small_* amount of EDTA after the reaction to mop up any leftover buffer ions, if you're sure you're finished doing enzymatic things.

Remember though that people were doing molecular work long before the nature of DNases and RNases were even properly figured out. DNases in particular are rarely blamed for bad times, though I know people working with RNA who have blamed RNases for a lot.. but then, you never know. Maybe the real problem was something else and they just assumed RNases were the problem for cargo-culty reasons.

*EDTA is a strong chelator and can be a nasty pollutant if overused, so try to make an effort to use only the amount you need, if you use it at all. Ideally you'd familiarise yourself with molar quantities of whatever ions you're trying to clear up (e.g. Mg++, Ca) and you'd only add a proportional amount of EDTA to the buffer or even less.

About the mineral oil that you find, I would say that could be a problema the DNase, RNase and protease present in it.
Check uct profile of the mineral oil PCR reagent: https://www.sigmaaldrich.com/content/dam/sigma-aldrich/docs/Sigma/Datasheet/2/m8662dat.pdf
it says:
Product Profile
DNase, RNase and protease: None detected
Suitable for use in the Polymerase Chain Reaction (PCR).

But, maybe if you warm up the mineral oil that you found during 30 minuts at 100ºC the enzymes should denaturalize, don't they?

Re: [DIYbio] Re: first, cheap and effective termal cycler PCR at home

I've used $3.99 mineral oil from CVS numerous times and it's never been a problem, 16s and ITS amplifications always work. Just add by eye to form a few millimeter thick layer on top of your sample.

Product Profile
DNase, RNase and protease: None detected
Suitable for use in the Polymerase Chain Reaction (PCR).

But, maybe if you warm up the mineral oil that you found during 30 minuts at 100ºC the enzymes should denaturalize, don't they?

Re: [DIYbio] Re: first, cheap and effective termal cycler PCR at home

About the mineral oil that you find, I would say that could be a problema the DNase, RNase and protease present in it.
Check uct profile of the mineral oil PCR reagent: https://www.sigmaaldrich.com/content/dam/sigma-aldrich/docs/Sigma/Datasheet/2/m8662dat.pdf
it says:
Product Profile
DNase, RNase and protease: None detected
Suitable for use in the Polymerase Chain Reaction (PCR).

But, maybe if you warm up the mineral oil that you found during 30 minuts at 100ºC the enzymes should denaturalize, don't they?

Re: [DIYbio] Re: first, cheap and effective termal cycler PCR at home

Hi Tom De Mets,

Here is the website where I've bought it: http://gaudi.ch/PocketPCR/ We'll see if it works...

About mineral oil, I don't know. I image that the oil should not have rest of DNA, proteases, DNases, or other molecules that can affect the PCR.

Firstly I will try without oil. Somebody in this post said that if your sample is big enough I will not need the oil.

Re: [DIYbio] Netflix Original Series - Biohackers

coverage in SCIENCE magazine...

I wanted to post a link but it has already been removed along with the source.

сб, 22 авг. 2020 г. в 22:46, Jérôme Lutz <jerome@synbio.info>:
It's a thriller and the director's goal was to place it 5 minutes into the future. However, with covid some parts are now a few months in the past, e.g. something comparable to the first scene in the train happend kind of similar at the German Austrian border. 

The Bio- and Bodyhacks that are shown are actually nice homages to experiments that were created by the community in the past. Also, there are references to the biohackers that did genetherapy on themselves as well as the human embryo experiments in Shenzhen. So in the end, it's something in between, but the story is of course fictional - luckily.

Of course, in a fictional movie you cannot make quotes but I would assume that those scenes are wonderful homages to the work of biohackers and body hackers.

So is this Netflix thing fiction or documentary?
