Identification of miRNAs and their targets regulated by LIF in trophoblastic cell lines

Aim of this study was to identify miRNAs which are regulated by LIF in different trophoblastic cell lines Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TaqMan Arrays. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed with a real-time thermocycler (ABI-7900, Applied Biosystems) per manufacturer's recommendations. miRNA profile of four trophoblastic cell lines was analyzed before and after LIF stimulation
