Researchers studied polyamines, molecules that promote healthy aging. They found that these same molecules can also help cancer cells grow. The team discovered how polyamines affect protein production and metabolism in cancer cells.

Polyamines are tiny molecules present in all living things. They play a crucial role in cell growth and specialization. Scientists have been studying these compounds, especially spermidine, for their potential to support healthy aging. This is because they stimulate autophagy, a process that helps cells recycle damaged components. However, researchers also found high levels of polyamines in many types of cancer, where they are linked to aggressive tumor growth. This contrast has puzzled scientists.

A team led by Associate Professor Kyohei Higashi from Tokyo University of Science in Japan investigated this connection. They used advanced molecular and proteomic methods to study how polyamines affect protein production and metabolism in cancer cells. The researchers reduced polyamine levels using a drug, then restored them with spermidine. This allowed them to directly measure the impact of polyamines on cancer cells.

The team found that polyamines primarily boost glycolysis, which is the process that quickly converts glucose into energy. They also discovered that polyamines increase levels of eIF5A2 and five ribosomal proteins, all of which are associated with cancer severity.
