As left ventricle mass increases with endurance training, diastolic function improves. As left ventricle mass increases with resistance training, diastolic function worsens. “Do I need to do cardio if I lift a lot and stay lean?” Yes, and walking doesn’t cut it, IMO.

Why do some genetic mutations devastate specific tissues while sparing others? We explore this question in GGC repeat disorders, revealing a mechanism linking protein aggregation to tRNA splicing failure in the brain. 🧵 on our new paper in Science: 🔗 science.org/doi/10.1126/sc…

These findings unexpectedly bridge two previously distinct concepts: - Neurodegeneration via protein aggregation - Neurodevelopmental disease via tRNA processing defects And, they suggest a possible therapeutic angle: Could restoring tRNA splicing help treat GGC repeat diseases?
