Five-qualifier claim
| Species / population | INK-ATTAC transgenic mice (BubR1 progeroid background). |
| Exposure, route, schedule | AP20187 inducer to trigger apoptosis in p16-expressing cells. |
| Comparator / duration | Vehicle-treated transgenic littermates; lifelong. |
| Endpoint / numeric result | Clearing p16-positive cells delayed onset of age-related changes in adipose tissue, skeletal muscle, and eye. |
| What it did NOT establish | Genetic tool in a progeroid model; not a drug and not a human result. |
