I have a hypoallergenic cat, two of them actually. Siberian Forest Cats. They're a breed that generally has low levels of FEL D 1, which is commonly what people are allergic to in cats. I have allergies to cats and dogs, but these cats I can be around with no problem. I can lay my face right on my cats fur and I won't have any issues.

Find a Siberian Forest Cat breeder near you and ask if they will either mail you some fur taken directly from a cat (often they will charge for this) or ask if you can visit their Cattery to spend some time around a cat or two.

Definitely worth looking into if you're seriously wanting a cat but have allergies. I hated cats until we got our poops.

They are both available.

The short-haired Devon Rex and Cornish Rex cats are thought to be less allergenic because they have less hair to shed, resulting in fewer saliva-coated particles in the air. Some people with allergies can also tolerate the hairless Sphynx.

Scientists created the GloFish by inserting fluorescent genes from jellyfish and sea anemones into the eggs of a silver and black zebra danio, a tropical fish from India. The fish was designed to help scientists determine when waterways were contaminated. If they glowed, it meant there were pollutants in the water.

Fluorescence and luminescence are different things. The first changes light of one wavelength to another (e.g. UV -> green). The second actually generates light, which requires the animal to allocate a lot of energy constantly and is more complex.

Just put a black light in your fish tank and call it a day.

Bioluminescence uses oxidative enzymes called luciferase to create a chemical reaction which produces light.

u/Thebraintickler 7d ago

Negative, luciferase is used in fireflies, it requires ATP to produce light.

this is a derivative of GFP, it uses a fluroflore inside of a protein and absorbs UV light and emits at a lower wavelength. The natural Green fluorescent protein has derivatives of Yellow, Red and Blue, subsequently known as YFP, RFP and BFP.

They actually market these things in stores called "GLO fish".

It was very weird because I worked a side job after grad school (where I used GFP and YFP to tag things occasionally) where I worked with tropical reef fish, and I came across these at a WalMart and was just like "wtf have they done...". I knew instantly that someone had just gotten these fish to express various GFP derivatives on their scales to do it, I just was interested/impressed in how they maintained the expression in animals with that kind of consistency. I was mainly tagging genes in E. coli or Arabidopsis (plant) and would use a standard antibiotic resistant plasmid control to keep expression, so I was convinced they had like a specialized diet, like how they used Lysine in Jurrassic Park. But nope. Still don't know how they did it. I've never worked with animals on a molecular level so a lot of that is just witchcraft to me, but I can grow high yield GFP in E. coli pretty well. I used to take it home and put it in my moms freezer to freak her out (I would purify it through FPLC, I had a PolyA tail added so it was quick, in case anyone was curious).

Like, all of my work with fluorescent proteins was straight up Jurassic Park shit, I had no real reason to do it, I just wanted to. "I was so obsessed with the fact that I could, I never stopped to think if I should" was literally what was going on. I was cloning a lot of genes in E. coli for a while and I think I intended to use GPF as a positive control but ditched the concept early on for some reason, but still had the gene so I just grew liters of it a few times to purify, as just a way to kinda look busy, but also to make shit glow.

20

u/Dat_Redox 7d ago

Instead of putting the gene on a plasmid or other piece of DNA that requires selection pressure to be replicated, they definitely just inserted it into the genome next to that of a protein expressed in the scales. That way since the protein is in the genome the fish will carry it without the need for selection pressure!

9

u/Thebraintickler 7d ago

I figured it was something like this, I'm assuming they did with adenovirus? My biggest question is if the fish are fertile, and if the offspring carry the gene, or if it's something done to the eggs and you can't breed the GFP genes.

Like, my biggest thing is with using bacteria and what little I've done with plants and tissue (immortal and primary) I can kinda go step by step on how to do this, but with a reproducing animal, not just dividing cells in media, I'm curious about it. I never tried to breed genetically altered arabidopsis, I was looking for peroxidase location in roots, which is like, really not what I do, it's just one of those things I got contracted out to do as a grad student.

My work with primary cell lines is very similar, it was from an animal model and I kinda discovered I really don't like using animal models. Actually, the thing that really did it for me was I was doing TEM work and I was sharing space with a guy who was doing live organ dissection, and watching the heart beat and all that shit with the skin pinned to a board just made me nope the fuck out of it. I'm not even a squeemish person, like, I've killed plenty of animals in my spare time, hunting, rattle snakes, being a kid with a slingshot and BB gun, etc, so I didn't think it would bother me as much as it did. It's also kinda why I attempted to go as far away from medicine as I could. I ended up working in medicine, but I don't have to deal with patients at all, it's all data work, which is fine.

But yeah, I kinda figured that's what they did, but I just don't know the actual technical steps to do it, so, like I said, it's basically witchcraft to me.

13

u/Burningshroom 7d ago edited 7d ago

They probably just used a restriction enzyme directly injected into an egg cell. This was a popular technique at the time the fish were originally produced and would guarantee inclusion of the gene in progenitor cells as the splice would be present in all the cells. It also means they only needed a single success as there is a single genome in an egg cell. With a few successful animals they could just selectively breed them to get homozygous progeny, which is easy because they fluoresce.

This is why they were originally created. Attaching a gene to the GFP would give an easy indicator for successful transformations and progeny.

mud bottoms and brown water are really popular

I feel like this makes the hobby really approachable. Just fill a tank with muddy water and tell people there are fish in it

It's an oversimplification. Dirted tanks are a thing, where instead of gravel or plain sand you use compost, soil etc, under a layer of sand. It provides good substrate and nutrition for plants.

Black water tanks are tanks with added tannins, either from making a tea and adding it or from adding material that will naturally release tannins into the water as it breaks down. The water isn't black, just darker. Many fish do better in it, and it looks kinda cool.

I think I should have been more clear. Beginners.

I can totally get behind making the environment as close to nature as possible.

But beginners, parents who got their kids a "my first fish kit", aren't going to want to spend the money for realistic environments.

The kids may be enthusiastic for a short time, but unless you catch on fairly quickly, there's only so much that a few fish in a tank are going to do to keep you. Short attention spans and all that. But the whole glowing thing just may be enough to keep them interested for longer, and become that kind of enthusiastic hobbyist.

I think a lot of hobbiests dislike fish like this because they appeal to the type of people that generally aren’t willing to create a proper environment for a fish to thrive in. Such as children.

u/AngusVanhookHinson 7d ago

Dude. Can you imagine a pond full of glowy fish? That's a great second step.

u/Spiked-bass4132 7d ago

That would be amazing but it appears they need a certan light to glow but glowing carp are definatly not the best beginner fish

not trying to be the killer of fun

u/AngusVanhookHinson 7d ago

I appreciate that. Maybe another species?

u/Spiked-bass4132 7d ago

Kinda already done to smaller fish https://www.glofish.com

u/Zappiticas 7d ago

To add to this, specifically the Glo danios are great for beginners. All of the other glofish still require a decently large tank, about 40 gallon minimum for the tetras and rainbow sharks. But the danios can be kept in a 10 gallon.

You say this from experience in the hobby? Or you know about carp? Genuinely asking cause I’ve been in the hobby for a long time and never seen carp sold like other hobby fish are; unless we’re talking about stocking a pond or something.

u/AngusVanhookHinson 7d ago

I'm not a hobbyist. I know nothing about them. So while my idea is getting some traction, I fear I may have accidentally been talking out of my ass.

Sorry if I came across as “WELL AKSHUALLY”. I was trying to convey that fish people are kind of crazy and picky, but I may have put myself in that category :)

I appreciate the admission. Carp can get pretty big compared to majority of the tropical fish you’d see in this hobby. They usually are only kept in ponds, lakes or extremely large fish tanks. This would be dead within months of a true beginner owning it.

Really cool! Can I get the source to this? I want to learn more!

By the way, don't wanna be this guy, but you misspelled "carp".

u/Jayer244 7d ago

If you want some infos on the method, those are called "Transgene organisms". A "transgene" is a gene is from another organism than the one where it is expressed in. In this case the gene cluster for bioluminescence was transfered from a jellyfish to a carp and expressed there.

You can do really cool stuff with transgenes and they're one of the main methods in genetic sciences today to gather knowledge about the function of the gene and how it is regulated or expressed. In fruit flies for example they've been used to make them grow legs out of the place where their eyes are and have eyes grow on their legs. Really interesting shit.

u/billythesid 7d ago

Transferring bioluminescence also creates a really obvious indicator of success for testing newly developed gene transfer methods.
