Indian Researchers Uncover How Low Oxygen May Slow Cancer Growth

• Systemic hypoxia, or reduced oxygen levels, is being explored as a new cancer treatment strategy.
• Researchers observed that while low-oxygen tumors often have poor prognoses, high-altitude populations show lower cancer mortality.
• Studies on mice with solid tumors revealed that lower oxygen levels significantly reduced tumor growth.
• Hypoxia suppressed the energy-intensive de novo synthesis pathway for purine nucleotides, limiting a key component for cancer cell division.
• Low-oxygen conditions also enhanced the effectiveness of chemotherapy drug gemcitabine and anti-CTLA4 immunotherapy.
