In female mice, when only the maternal X chromosome (Xm) is active, older animals show worse memory 🧠🕳️ than those with random X-inactivation. This is due to imprinted genes — some only expressed from the paternal X (Xp) — which are silent when Xm dominates. &amp;nbsp; 🧠💡 Using CRISPR–Cas9, researchers reactivated 3 Xm-silent genes (Sash3, Tlr7, Cysltr1) and saw improved memory and mitochondrial function ⚡🔋. &amp;nbsp; 👩‍🔬 This highlights inter-female variation in aging and memory — and suggests that epigenetic inheritance from mothers may shape how well we remember… or forget. 🧓🧠❓ Dr. RR Baliga's 'Podkast for the Kurious Doc' http://www.MasterMedFacts.com <iframe title="Libsyn Player" style="border: none" src="//html5-player.libsyn.com/embed/episode/id/35819990/height/300/theme/custom/thumbnail/yes/direction/forward/render-playlist/no/custom-color/88AA3C/" height="300" width="600" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe> https://assets.libsyn.com/secure/content/186102565
