AFAP1-AS1 was highly expressed in OS tissues. (A) Relative expression levels of AFAP1-AS1 in 49 paired OS tissues and adjacent normal tissues. (B) RT-qPCR analysis showed that AFAP1-AS1 was upregulated in OS cell lines compared to hFOB1.19 cells. (C and D) Kaplan-Meier analysis was conducted to measure the probabilities of overall and progression-free survival in OS patients based on AFAP1-AS1 expression levels. The results represented three independent experiments and were expressed as mean ± SD. *P<0.05 and **P<0.01 vs. the control group. OS, osteosarcoma; RT-qPCR, reverse transcription-quantitative polymerase chain reaction.
