E74‑like E26 transformation‑specific (ETS) transcription factor 3 (ELF3), is a member of the ETS transcription factor family, and has been characterized as an epithelial cell‑specific transcription factor. The role of ELF3 in tumor progression remains to be elucidated. Previous studies have indicated that loss of ELF3 mRNA and protein expression was associated with poor outcomes in ovarian cancer (OC). By contrast, the present study demonstrated that ELF3 was upregulated in OC, using data from The Cancer Genome Atlas, and elevated expression levels of ELF3 were associated with a poor prognosis. ELF3 promoted OC cell proliferation in vitro and in vivo. The present study revealed that ELF3 inhibited apoptosis and reduced the cisplatin sensitivity of OC cells. Furthermore, the mTOR pathway was found to be activated by ELF3. Collectively, the results of the present study indicated the role of ELF3 in the development and pathogenesis of OC.
