Exploring the genetic overlap between obstructive sleep apnea and prostate cancer

Area of Science:

• Genetics
• Oncology
• Sleep Medicine

Background:

• Obstructive sleep apnea (OSA) is linked to increased cancer risk, particularly prostate cancer.
• The genetic overlap between OSA and cancer comorbidity requires further investigation.
• Understanding shared genetic factors is crucial for elucidating disease mechanisms.

Purpose of the Study:

• To identify shared risk genes between obstructive sleep apnea and cancer.
• To analyze the molecular pathways associated with these common genes.
• To explore the potential common molecular etiology underlying OSA-cancer comorbidity.

Main Methods:

• Identified genes common to both OSA and cancer.
• Assessed the statistical significance of the gene overlap.
• Performed pathway enrichment and protein-protein interaction analyses on the intersecting gene set.

Main Results:

• Identified 68 common genes between OSA and cancer, a number exceeding random chance.
• The shared gene list was significantly associated with pathways related to hypoxia, apoptosis, oxidative stress, and cell cycle proliferation/damage.
• A 17-node protein interaction network revealed key proteins within these enriched pathways.

Conclusions:

• A common molecular etiology underlies the comorbidity of OSA and cancer.
• Enriched pathways including proliferation, apoptosis, and hypoxia suggest their critical role in the shared pathophysiological processes.
• These findings provide a molecular basis for the observed association between OSA and cancer risk.
