Exercise-to-Angiogenesis Route
Exercise-to-angiogenesis is a strong mechanistic route for muscle gene therapy, but this material still gives no outcome data that would make it medicine.
Short version: this route is plausible, but it is not medicine yet.
HIIT and sprint intervals make muscle build vessels the hard way: shear stress, hypoxia, myokines, AMPK-PGC-1alpha signaling, mitochondrial biogenesis, lactate handling, and cardiovascular remodeling.
The editing idea is simpler on paper: push pro-angiogenic programs in skeletal muscle, for example with VEGFA or HIF1A. Against age-related microvascular rarefaction, the target is reasonable: preserve oxygen delivery.
Thin part: no anchor quote is stored, and this material gives no outcome data. Strong mechanism is not proof of treatment.
Next: measure capillary density, oxygen delivery, dose-response, durability, and safety in aged muscle. Until then, this is a route, not a therapy.
Selected because the pathway links a well-defined training adaptation to a measurable pro-angiogenic editing target while clearly separating mechanism from clinical proof.
