Hypothesis
This study aims to develop a novel hypoxia-related prognostic score (HPS) based on hypoxia-associated genes to improve CRC prognostication and inform treatment strategies.
Conclusion
The hypoxia-related prognostic score (HPS) captures the regulatory influence of TME hypoxia on immune responses, offering valuable insights into its role in tumor progression.
Supporting Evidence
- Higher HPS values corresponded to increased infiltration of immune-suppressive cells and reduced presence of anti-tumor immune cells.
- Seven hypoxia-associated signature genes were identified, each demonstrating a strong correlation with CRC prognosis.
- Patients with a worse prognosis exhibited higher hypoxia scores.
Takeaway
This study found that low oxygen levels in tumors can make it harder for the immune system to fight cancer, and they created a new score to help predict how patients with colorectal cancer will do.
Methodology
Transcriptomic data from CRC patients were analyzed using Lasso regression to identify hypoxia-associated genes, which were validated in vitro.
Participant Demographics
Patients with colorectal cancer from multiple datasets.
