Relative expression levels of lncRNA CASC11 in cervical cancer tissues. a CASC11 expression was assessed by RT-qPCR assay in cervical cancer samples (n = 50) and adjacent normal samples (n = 50), and CASC11 was up-regulated in cervical cancer. b The expression level of CASC11 was evaluated by RT-qPCR assay in FIGO stage I (n = 38) and FIGO stage II (n = 12), and CASC11 was positively related to the FIGO stage. c The expression level of CASC11 was analyzed by RT-qPCR assay in tumor tissues (tumor size < 4 cm, n = 38) and tumor tissues (tumor size ≥ 4 cm, n = 12), and CASC11 was positively related to the tumor size. d Kaplan–Meier test showed that high level of CASC11 was significantly associated with the low survival rate for cervical cancer patients. CASC11 expression was detected by RT-qPCR analysis and normalized to GAPDH expression (n = 25, respectively). Error bars represent the mean ± SD of 3 independent experiments. *p < 0.5; **p < 0.01
