Despite advancements in molecular profiling, the mechanisms driving GC proliferation and metastasis remain unclear. This study identifies Early 2 Factor 4 (E2F4) as a key transcription factor that promotes GC cell proliferation, migration, and invasion by upregulating DNA Replication and Sister Chromatid Cohesion 1 (DSCC1) expression. Bioinformatics and transcription factor analyses revealed E2F4 as a significant regulator of DSCC1. Functional assays confirmed E2F4’s role in enhancing GC cell malignancy in vitro and in vivo. Knockdown and overexpression experiments demonstrated that E2F4 positively regulates DSCC1 at the transcriptional level, with ChIP-qPCR and dual luciferase reporter assays validating the binding sites on the DSCC1 promoter. These findings highlight the E2F4-DSCC1 axis as a potential therapeutic target to mitigate GC progression.  \nKeywords: Gastric Cancer; DNA Replication and Sister Chromatid Cohesion 1; Early 2 Factor 4; transcription; Proliferation  \nIntroduction  \nGastric cancer (GC) is a profoundly deadly disease on a global scale, standing as the fifth most commonly detected cancer and the fourth leading contributor to cancer-related mortality internationally [1] . In recent times, advancements in high-throughput and genomic technologies have enabled the study of gastric cancers at the molecular level. The availability of molecular profiling data has significantly aided in pinpointing potential gene driver alterations in GC, including gene mutations, chromosomal changes, alterations in transcription patterns, and irregularities in epigenetic modifications[2-4] .
