Endometrial cancer (EC) remains a lethal gynecological malignancy with limited therapeutic options owing to unresolved pathogenesis. Cellular senescence acts as a key barrier against tumorigenesis in cancer cells, thus investigating its role in EC progression represents a pivotal research avenue to address these challenges. This study reveals the critical role of cellular senescence in EC progression through multi-omics profiling and functional validation. The integrative analysis of RNA-seq and clinical datasets identified Na
