While researching how hormones affect animal's social behavior, scientists managed to make gene-edited hamsters full of rage.
A group of researchers made gene-edited hamsters that were meant to be less aggressive. The researchers used CRISPR, a gene-editing platform, to remove a gene they believed was responsible for aggressive behavior in hamsters. However, the genetic modification had a much different effect. Instead of being more docile, the hamsters became overly aggressive.Image source: stockcrafter / Adobe
Several decades ago, back in the early 1980s, a group of researchers discovered that a hormone known as arginine vasopressin could change the behavior of hamsters. From here, the scientists dug deeper into the differences between the sexes of hamsters and the AVP receptor, called Avpr1a. It’s this hormone that was changed in the gene-edited hamsters.
The researchers used CRISPR-Cas9 to remove the Avrpr1a receptor gene in both male and female hamsters. As with the mice, they expected it to reduce aggression levels overall. However, that hypothesis was incorrect. Instead, the female and male gene-edited hamsters both became more aggressive. They were even going so far as to attack other hamsters of the same sex.
