CRISPR experiments in killifish show vgll3 can speed development but raise cancer risk and reduce lifespan.

The Gene Is Called vgll3

Researchers Used African Turquoise Killifish

CRISPR Changed Different Forms of the Gene

Mutant Males Reached Maturity Earlier

They Also Grew Faster and Larger

Their Cells Divided More Aggressively

DNA-Damage Responses Were Altered

Older Males Developed Melanoma-Like Tumours

Faster Development Came With Shorter Lives

The Findings Do Not Yet Apply Directly to Humans

Scientists have identified a gene that helps regulate a striking biological trade-off between rapid development and longer life. The findings involve vgll3, a gene whose activity influences growth, sexual maturity, cell division and age-related disease.

The study does not show that people possess a switch that literally preserves youth. Researchers altered the gene in African turquoise killifish, causing some animals to grow and mature faster—but later develop more cancer and die sooner.
