Dietary α-ketoglutarate modulates lung adenocarcinoma growth and epigenetic remodeling in a sex-dependent fashion.

Dietary α-ketoglutarate reduces lung adenocarcinoma growth in females but promotes it in males, through sex-dependent epigenetic remodeling.

• Why it matters: Lung adenocarcinoma is a leading cause of cancer death, and new preventive strategies are urgently needed. Understanding sex-specific responses can improve targeted interventions.
• What they did: Researchers administered dietary calcium α-ketoglutarate to mice and analyzed tumor growth, histone modifications, and gene expression, revealing sex-dependent effects on tumor progression.
• The result: Findings show α-ketoglutarate modulates epigenetic marks and gene expression differently in males and females, suggesting its potential as a sex-specific chemopreventive agent in lung cancer.
