Scientists reveal why a popular anti-aging compound may also fuel cancer
Why it matters: This discovery is critical for developing safer anti-aging therapies and more targeted cancer treatments, as it clarifies how a single molecule can have such contrasting effects on human health.
- Polyamines, natural molecules celebrated for promoting longevity by boosting cellular cleanup, are also consistently found at high levels in aggressive cancers (Tokyo University of Science).
- eIF5A1, a protein crucial for polyamine's anti-aging benefits, differs significantly in function from its close relative eIF5A2, which is linked to cancer development, despite their similar structures (Tokyo University of Science).
- Cancer cells exploit polyamines to alter their metabolism, specifically through aerobic glycolysis, a mechanism now better understood thanks to this research (Tokyo University of Science).
A new study from Tokyo University of Science reveals that polyamines, popular anti-aging compounds, may also fuel cancer growth by activating distinct metabolic pathways in tumor cells, solving a long-standing scientific puzzle.
