The levels of C19MC miRNA were determined by RT-qPCR in BeWo cells (A) or U2OS cells stably expressing a BAC containing the C19MC miRNA cluster (B). The cells were exposed to IFN lambda-1 (10 ng), and the expression levels of miR-512-3p, miR-517a, miR-525-5p, and miR-1323 were quantified, normalized to RNU6B. Experiments were performed three independent times. Data are shown as mean ±SD (* p<0.05).
