CASC7-regulated PTC cell behavior through sponging miR-34a-5p. a Cell viability assessed by MTT assay, b cell apoptosis determined by flow cytometry following Annexin V and PI staining, and c cell migration assessed by Transwell migration assay in human PTC cell lines (K1 and TPC-1) co-transfected with miR-34a-5p mimic/mimic NC and CASC7 overexpression vector/empty vector. *P < 0.05, **P < 0.01 vs. mimic NC + Vector; ^##P < 0.01 vs. mimic NC + CASC7 or Vector + miR-34a-5p mimic. Data are expressed as the mean ± standard deviation (n = 3)
