(A) Cervical tissues extracted from human patients. QRT-PCR was used to compare miR-505-5p expression levels between CC tissues (Cervical cancer, n=60) and non-cancerous cervical tissues (Normal cervical, n=60) (**P<0.01; by Student’s t-test vs normal cervical tissues). (B) QRT-PCR was applied to measure miR-505-5p expression levels in in vitro cervical cancer cell lines, Ca-Ski, HeLa, SiHa, C-33A and HT-3, and then normalize them to miR-505-5p expression in a non-carcinoma cervical epithelial cell line, Ect1/E6E7 (*P<0.05, **P<0.01; by Student’s t-test vs Ect1/E6E7).
