Alcohol-Induced Metabolic Stress Sensed by m6A-Modified ChREBP Drives Immune Evasion in Esophageal Carcinogenesis.

Alcohol-sensitive ChREBP epitranscriptomic modification promotes immune evasion and drives esophageal squamous cell carcinoma in over 200,000 individuals.

• Why it matters: Understanding how metabolic stress from alcohol contributes to esophageal cancer can reveal targets for prevention and therapy, addressing a major health risk.
• What they did: A trans-ancestry meta-analysis identified a germline variant at the MLXIPL locus that increases ESCC risk in drinkers, with functional studies showing m6A modification stabilizes ChREBP transcripts, amplified by alcohol.
• The result: Targeting the ChREBP-ATF3 pathway or immune checkpoints like PD-L1 effectively suppressed tumor progression and restored immune infiltration, highlighting potential therapeutic strategies.
