This study aims to elucidate the molecular mechanisms by which COMT suppresses cell invasion and to evaluate its significance as a prognostic marker. We performed transcriptome analysis (RNA-seq) on ovarian cancer cells to identify downstream targets of COMT. Our results show that COMT overexpression significantly inhibits cell invasion in an estrogen-independent manner. Integrative analysis of RNA-seq and CE-MS metabolome data revealed that COMT upregulates desmoglein genes (DSG1-3), thereby strengthening cell-to-cell contact, and induces metabolic remodeling. These findings suggest that COMT suppresses metastasis by regulating cell adhesion and metabolism, serving as a potential prognostic marker and therapeutic target in ovarian cancer.2026/05/26GSE330672GSM9730114GSM9730113GSM9730112GSM973011123227330672Homo sapiens
