Germ cells are the only cells that contribute to the next generation.
“The germ cells are supposed to be the only cells that contribute to the next generation”

Brain information should not transfer directly to the next generation.
“the brain shouldn't be able to transfer to the next generation”

About 90% of sperm and egg modifications are removed during mammalian reprogramming.
“Most of the modifications in the sperm and in the egg are removed, so about 90% of them.”

RNA may transmit information between generations.
“RNA has a lot of potential for doing that, as we'll explain soon.”

Humans and model organisms evolved from a common ancestor.
“we all evolved from the same ancestor”

C. elegans has 959 cells, including 302 neurons.
“A C. elegans nematode always has 959 cells, out of which 302 are neurons.”

C. elegans has a three-day generation time.
“The generation time in C. elegans is 3 days.”

C. elegans clearly demonstrates inheritance of acquired traits.
“In the worm, we now have very obvious and clear-cut proof that there is inheritance of acquired traits.”

Double-stranded RNA silences matching genes in injected worms.
“if you inject the worms with RNA molecules which are double-stranded, they shut off the genes that match in sequence to this RNA.”

Some drugs now use RNA interference.
“there are now drugs that use this mechanism”

Somatic double-stranded RNA injection can affect germ cells and offspring.
“if you inject the double-stranded RNA just to somatic cells, even to the head, you will get also the effect in the germ cells and in the next generation.”

Ingested RNA-induced silencing spreads through worms and into offspring.
“the silencing would move from the site of ingestion, from the gut where the bacteria are eaten, to the rest of the body and also to the next generation.”

Inherited small RNAs protect C. elegans offspring from viral replication.
“All the worms' progeny, although they don't have the gene that is needed for making the small RNAs, are black. They silence the virus.”

Small-RNA-mediated antiviral protection persists across additional worm generations.
“And this also continues for additional generations.”

Small RNAs are leading candidates for transmitting stress or harmful effects across mammalian generations.
“It is true that also in mammals, RNAs and small RNAs are a leading candidate for something that could mediate the transmission of stress protection or also of harmful effects that transmit between generations.”

In C. elegans, brain small RNAs can alter behavior in subsequent generations.
“What we did in C. elegans is we showed that the brain can communicate with the next generations using small RNAs and that this can change behavior.”

Brain small-RNA changes affect offspring food-finding capacity for three generations.
“this changes the capacity of the worms in the next generation to find food, not only in one generation but 3 generations down the road.”

Sage2 is a germline gene involved in the inherited behavioral effect.
“One gene is called Sage2.”

RNA-mediated inheritance requires a protein that carries RNA between generations.
“If you don't have the protein that physically carries the RNA between generations, it doesn't happen.”

No comparable small-RNA amplification mechanism is known in mammals.
“In mammals, we don't know of such an amplification mechanism.”

Exercise can correct overfeeding-related inherited effects in rodents.
“there are experiments in rodents where they show that overfeeding the rodents creates problems for the next generations, for the children. However, if you let the rodent exercise, then it corrects the aberrant inheritance.”

RNA-based inheritance research could enable diagnostics for prospective parents.
“what you could do perhaps even in the not so far future is use this for diagnostics, DNA-based diagnostics for every couple that wants to have a kid.”

Future IVF could use exercise-modified RNA profiles to select or prepare embryos.
“If we understand this and it's true, we can say maybe you should run on the treadmill a little bit. This will change the profile of your RNAs and then we will use it for IVF.”
