RFC3 Knockdown Decreases Cervical Cancer Cell Proliferation, Migration and Invasion

Cancer Genomics Proteomics. 2025 Jan-Feb;22(1):127-135. doi: 10.21873/cgp.20493.

Abstract

Background/aim: Replication factor C subunit 3 (RFC3) is a critical component of the replication factor C complex, which is essential for DNA replication and repair. Recent studies have highlighted the RFC3's significance in various cancer types. Herein, we aimed to elucidate its biological role in cervical cancer.

Materials and methods: Cervical cancer cells were transfected with RFC3 or control siRNA. Cell viability was assessed using the MTT assay over a 4-day period and its clonogenic potential was determined using colony formation assays. Flow cytometry analysis was performed to evaluate cell cycle distribution. Transwell migration and invasion assays were performed to assess the migration and invasion abilities of cervical cancer cells.

Results: RFC3 knockdown significantly inhibited cell proliferation, induced cell-cycle arrest, and decreased migration and invasion in HeLa and ME-180 cells compared to control siRNA-transfected cells.

Conclusion: The crucial role of RFC3 in cervical cancer progression is highlighted. RFC3 knockdown resulted in decreased cervical cancer cell proliferation, migration and invasion, suggesting its potential as a therapeutic target in cervical cancer.

Keywords: RFC3; cervical cancer; invasion; migration; proliferation.
