Abstract in brief
The study shows that as male rats age, the methylation (a chemical change that can turn gene activity down) of the Igf2 gene in the hippocampus increases, leading to lower Igf2 expression, which is linked to memory decline.
Increasing methylation of the Igf2 gene is associated with worse synaptic plasticity and memory in older rats, which are key factors in learning and memory formation.
Using a targeted gene editing technique (CRISPRdCas9) to reduce methylation on the Igf2 gene improved memory and brain function in aged rats, suggesting that reversing this methylation could help combat age-related cognitive decline.
