Abstract
Serum response factor (SRF) is a transcription factor that has important roles in tumor progression. However, its role in cervical cancer cell proliferation and invasion remains unclear. The present study revealed that SRF silencing constrained cervical cancer cell proliferation and invasion via controlling early growth response‑1 (Egr‑1). The results demonstrated that SRF was significantly increased in cervical cancer tissues and cell lines, compared with normal. Suppressing SRF, by using a loss‑of‑function experiment, constrained cervical cancer cell proliferation, invasion, and epithelial‑mesenchymal transition. Furthermore, SRF knockdown significantly downregulated Egr‑1 expression in cervical cancer cell lines, and overexpression of Egr‑1 reversed the effect of SRF on cell proliferation, invasion, and epithelial‑mesenchymal transition. Therefore, SRF may control cell proliferation and invasion by regulating Egr‑1 in cervical cancer.
