UBC9 overexpression promotes proliferation and metastasis in gastric cancer via ATF2.

ABSTRACT: Gastric cancer remains a leading cause of cancer-related mortality worldwide, characterized by poor prognosis due to its aggressive nature and high metastatic potential. While the E2-conjugating enzyme UBE2I (UBC9), essential for SUMOylation, has been implicated in various cancers, its precise role in gastric cancer remains poorly understood. In the study, we demonstrate significant UBC9 overexpression in gastric cancer tissues, which correlates with poor clinical outcomes. Functional analyses revealed that UBC9 knockdown significantly suppressed gastric cancer cell proliferation, migration, and invasion in vitro and in vivo, whereas UBC9 overexpression enhanced these malignant phenotypes. Through integrated transcriptomic and proteomic analyses, we identified ATF2 (Activating Transcriptio
