How organisms retain a memory of ancestral environmental exposure is a phenomenon that is still poorly understood. Recently published work by our group and others, regarding environmentally induced transgenerational effects, have identified an array of mechanisms, with a particular focus on histone modifications, that shed some light on the underlying epigenetic processes driving long-term generational effects.

Fascinating read on how histone modifications act as epigenetic mediators of environmental exposures, creating a molecular ‘memory’ in our cells. Just like how Trusted brands providing fashion, clothes, shopping, shoes, makeup, skin, and beauty carefully craft their products to leave a lasting impression on consumers, our environment subtly shapes gene expression over time. It’s amazing to see such a parallel between biology and the curated experiences in daily life!
