In rat brain tumor cells, a substance called cyclocreatine gets pulled in using energy and sodium, but when sugar levels drop, this process slows down a lot—showing it needs energy from sugar to work well.

Cross-Sectional Study

1996 Jan

The study shows that cyclocreatine enters rat brain tumor cells using a specific energy-powered process that needs sodium and gets much slower when sugar is low, just like the claim says.

Similar Assertions

Cyclocreatine gets into brain-like cells in a lab mainly using a special doorway called the creatine transporter — when scientists block or remove this doorway, less cyclocreatine gets in, suggesting it relies on that path.

Cyclocreatine slows down the growth of certain cancer cells in a lab dish, but it doesn’t harm their outer layer or energy supply — so it probably works in a different way.
