Then one day they start charging rent — breath, knees, and grip, all at once. Most people blame age and start reading supplement labels.

Three groups ran side by side: young controls (20 weeks old), middle-aged controls (53 weeks), and the treated middle-aged group.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">Body weight stayed near the young controls, not the heavier middle-aged ones.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">Both clinical and performance frailty scores dropped to near-young levels.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">In the open-field test they moved more; in grip and lifting tests they lifted more; on the inverted-screen test, the \"hold on\" latency stretched longer — the classic signature of stronger, less frail animals.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">The details hold up. Gastrocnemius weight survived, and the muscle-to-body-weight ratio stayed near young levels. Their muscle kept its microvasculature: capillary density and vessel integrity stayed intact. And the bone — femur weight-to-body-weight ratio climbed back to young levels, trabeculae widened, osteoblasts rose significantly, and the osteocyte population that shrinks with age showed signs of recovery.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">The mechanism reads like teamwork: in muscle, better microcirculation and less fibrosis; in bone, more osteoblasts rebalancing formation against resorption.

Its survival leans on a protein called survivin, which lets cancer cells dodge apoptosis, the cell's programmed death. Survivin is hard to attack directly.
