Fig. 2From: Long noncoding RNA FER1L4 promotes the malignant processes of papillary thyroid cancer by targeting the miR-612/ Cadherin 4 axisFER1L4 promoted PTC cell proliferation. A The expression of FER1L4 was efficiently knocked down using siRNA. B Knockdown of FER1L4 inhibited K-1 and TPC-1 cell growth by conducting CCK8 assays. C Artificially enhanced expression of FER1L4 in PTC cells. D Cellular growth curves of PTC cells treated with FER1L4 vector or empty vector. E, F Colony-formation numbers of PTC cells transfected with siRNA targeting FER1L4, and FER1L4 expression vector, compared with negative control. G, H The cellular proliferative rate was measured by EdU incorporation assays in PTC cells treated with siRNA targeting FER1L4 and FER1L4 expression vector, compared with negative control. Scale bars = 100 μm. Error bars, mean ± SD. * P < 0.05; ** P < 0.01; *** P < 0.001Back to article page
