Published in the journal Biological Psychiatry, it targeted on a gene acknowledged as CRF-1, which is linked to the body’s tension-control system in the brain.
The researchers used female rats that were 45 days old, parallel to adolescence in people. Some of the rats have been exposed to “minor” anxiety, which incorporated alterations in temperature and everyday schedule for a week.
They have been compared with a manage group that was not exposed to pressure at all.
The rats have been mated and conceived two weeks later.
In the 1st element of the study, the researchers examined the ova of the rats that had been exposed to stress just before they conceived. They discovered that there was higher expression of the CRF-one gene.
For the 2nd portion, the researchers examined the brains of newborn rats quickly right after birth.
They discovered that even at that stage there was greater expression of the CRF-1 gene in the brains of the rats born to mothers who had been exposed to anxiety.
Hiba Zaidan, a researcher, said: “Until now we saw evidence only of behavioural effects. Now we’ve located proof of results at the genetic degree.
“We are learning more and a lot more about intergenerational genetic transfer and in light of the findings, and in light of the fact that in today’s reality numerous ladies are exposed to stress even just before they get pregnant, it is critical to research the degree to which this kind of phenomena get spot in humans.”
