Oh wow! I remember doing electroporation experiments in my biotechnology courses in college. I never thought about applying the same concepts with electric eels and eDNA!

Thanks for sharing!

Could this possibly be done with humans eventually? And to what extent are the able to affect the DNA?

This electrophoresis effect is actually already known and is one of the strategies to deliver gene editing molecules. This article has merely found and reasoned that the shock produced by an eel can be enough to make the cell membrane more permeable to outside DNA. Here is a paper that discussed the famed CRISPR/Cas9 and mentions certain strategies for delivery including electrophoresis: https://pmc.ncbi.nlm.nih.gov/articles/PMC5723556/

My opinion/reasoning on the eel study is I think they are hyping it up too much. It sure is exciting but I don't think it will be what they make it out to be. This could drive evolution, however cells have autoimmunity mechanisms. For example, when DNA shows up in the cytoplasm, which is where any DNA via electrophoresis will end up, the cell has DNAses in lysosomes that will degrade this invading DNA. Dysfunction of these DNAses is an autoimmune disorder. Additionally, if this DNA did make it into the nucleus, it would be a cell or a group of cells. Your entire body won't be edited. To actually pass down this DNA to any offspring, the DNA needs to make it in your germ cells (egg/spermatogonium), not a few cells in your skin. And DNA won't be able to pass far enough to make it through all the tissue to edit these germ cells with such a short pulse of shock. The next question is what about bacteria? Well the same research group has done some probing into this topic and has had no luck, but I am sure they are or have worked on research that is specific to bacterial DNA inheritance.

Here is a paper on this: https://pmc.ncbi.nlm.nih.gov/articles/PMC3683625/#F2

It’s worth noting that the CRISPR/Cas9 system is derived from a bacterial (Streptococcus pyogenes) immune defence system against foreign DNA.

Pfft, applying electroporation principles to electric eel eDNA should be the first idea that occurs to students who are paying attention in their biotechnology courses. Slacker.

Eels need to be studied more. I know electric eels arent actually eels but rather a type of knifefish, but we should be studying all the long fish. I have an eel in my living room and its incredibly intelligent.

yes, I can hold the eel, she is super slippery.

u/jillisonflook 8h ago

Please tell me more!! I love knowing good eel stories!!

u/Markofdawn 8h ago

I have taught her to swim laps if she wants dinner now. I usually go to bed around 3-4am which is when she is most active and when i move to my bedroom door she snaps and makes bubbles so i notice her and feed her more. Her name is Celeste-eel

u/vacconesgood 8h ago

If she's cheeky she's Unagi.

Celeste-eel is so good!!! Love this. Glad I asked. Appreciate you.

u/Markofdawn 8h ago

I have had her for almost 5 years with next to no prior fishkeeping experience. Currently have a tank weighing close to 1000kg in my living room. Only twice in this time has she attempted to leave, fallen 2-3feet to the floor, got covered in dog hair and gave up , to be deposited into the tank in the morning by the first awake. I assume my dogs were very confused when they heard the slap. Rambunctious youth eel. She lives in a cozy PVC pipe and enjoys watching people use the front door and sticking her face in the outflow pipe.

Short fin eel (Australia)

u/SignalDevelopment649 7h ago

Genuine question, how intelligent would you say a Short Fin Eel is, if we're to compare it to a Moray Eel?

8

u/Markofdawn 6h ago

I have absolutely no idea about Morays, aside from what my father told me from his scuba diving years(they like to bite fingers) I do however own a plethora of other animals and I'd say they're as intelligent as a chicken or a rabbit. Definitely able to distinguish between two faces as far as i can tell. Quite spatially aware too, as when i walk into my office she tries to "follow" me through the tank. Extra wiggly at 5am. Loves to catch morning sun on her tummy.

4

u/SignalDevelopment649 6h ago

That's pretty damn impressive (not sure if the personality she has or the facial memory is the more impressive part, but impressive it is all the same), thank you for telling me that. Does she allow any physical contact, petting or just swirling around your hands or something? And she sounds absolutely adorable!

Morays are incredible too, worth a solid read on them. For starters - they're known for interspecies cooperation for hunts, and are able to remember and and recognise "their" humans after years of not seeing them at all. Also they do cuddle to them, in their own, eely way.

u/PM_ME_UR_ROUND_ASS 5h ago

Yep, and that classification is actually super relevant to this discovery - knifefish have specialized electric organs derived from muscle tissue that generate these zaps, which is way diffrent from how true eels produce electricity!

AMAZING SPIDERMAN 2 (2014) WAS SCIENTIFICALLY ACCURATE*

A recent study has found that the electricity produced by an electric eel’s discharge is strong enough to cause the transfer of genetic material from the environment into the cells of nearby animals. The finding suggests that electric eels – and other electricity-generating organisms – could affect genetic modification in nature.

In the lab setting, electroporation involves the application of an electric field to cells to increase the permeability of their cell membrane, which allows foreign DNA to be introduced. It’s the technique that’s used to produce the knockout mice that are used in research experiments, as well as in tumor treatment and gene- and cell-based therapies.

25

u/jillisonflook 9h ago

Now, a new study by researchers from Nagoya University in Japan suggests that the electric eel is capable of electroporation in its natural environment.

“I thought electroporation might happen in nature,” said Atsuo Iida, corresponding author of the study. “I realized that electric eels in the Amazon River could well act as a power source, organisms living in the surrounding area could act as recipient cells, and environmental DNA fragments released into the water would become foreign genes, causing genetic recombination in the surrounding organisms because of electric discharge.”

It hasn’t been observed in the wild and it’s preliminary research. Basically if there is foreign DNA in the area an electric eels zap is so strong that some of the DNA could sneak into your cells.

According to the internet.

u/clandestineVexation 28m ago

Humans do this intentionally, it’s called electroporation. Basically electricity makes cell membranes open up a little bit, and allows DNA molecules to go through. There’s DNA just floating in the environment (because there’s life everywhere) and the eel accidentally makes this happen with its shock
