MedComm – Oncology, Volume 4, Issue 3, September 2025.BALF4, a highly expressed viral gene in EBVaGC, plays a tumor‐suppressive role in GC progression. The mechanism involves BALF4's interaction with the RNA acetyltransferase NAT10, through which it promotes NAT10's ubiquitination and subsequent degradation.
