Description

Jiahao Liu and colleagues report a 2026 study of GALNT7, an enzyme that attaches sugars to proteins, in gastrointestinal stromal tumors. These tumors run on abnormal KIT signaling, and resistance to KIT-blocking drugs remains a serious problem. The team combined bulk, protein-level, and single-cell data to find which sugar-adding enzymes matter most.

GALNT7 emerged as the hub, raised in tumors and tied to poorer progression-free survival. In cell and mouse experiments it sped tumor growth, movement, and graft formation. The mechanism ran through KIT itself: GALNT7 attached a specific sugar mark that stabilized the KIT protein and kept its growth signals on. A sugar-blocking compound reversed these effects and shrank grafts. The authors nominate GALNT7 as both a warning marker and a drug target.
