Promising but preliminary

Enhanced acetate uptake and metabolism in endothelial cells promote tumour angiogenesis and immunosuppression by increasing histone acetylation.

Blocking a metabolic pathway in tumor blood vessels enhances immunotherapy effectiveness against liver cancer in laboratory models.

Hepatic acetate accumulation drives MCT1/ACSS2 upregulation in tumor endothelial cells, increasing H3K27ac-mediated pro-angiogenic and immunosuppressive transcription; ACSS2 inhibition synergizes with anti-PD-1 to suppress HCC progression and enhance CD8+ T-cell immunity. This record was retained from the prior triage attempt for PubMed pipeline handoff.

Why it surfaced

Published in Gut (top GI/hepatology journal); identifies a completely novel metabolic immune suppression pathway in tumor endothelial cells; strong preclinical mechanistic evidence with therapeutic synergy data; highly actionable for HCC immunotherapy combination strategy.
