ILF3-AS1 expression is downregulated in CC tissues. (A) GEPIA database analysis demonstrated that ILF3-AS1 expression was downregulated in CC tissues compared with healthy tissues. The red box represents CC tissues and the gray box represents healthy tissues. (B) Low ILF3-AS1 expression levels were associated with the stage of CC. (C) GEPIA database analysis of overall survival in patients with CC. (D) Reverse transcription-quantitative PCR was performed to measure ILF3-AS1 expression levels in CC tissues (stage I/II=15; stage III/IV=17) and ANTs (n=32). All experiments were repeated three times. *P<0.05 and ***P<0.001 vs. healthy tissues or ANTs; ^^^P<0.001 vs. stage I/II. ILF3-AS1, ILF3 divergent transcript; CC, cervical cancer; GEPIA, Gene Expression Profiling Interactive Analysis; ANT, adjacent tissue; lncRNA, long non-coding RNA; CESC, cervical and endocervical cancer; T, tumor; N, healthy; TPM, transcripts per million.
