Real-time quantitative RT-PCR
Total RNA was isolated from cancer cells and HUVECs
using Trizol (Invitrogen), and cDNA was synthesized following
standard protocols. Mature miR-494 was quantified
by Taqman microRNA Assay (Life Technology) with U6
as control. Real-time PCR involved SYBR Green dye and
Taq polymerase. Please see supplemental materials for the
primer sequences.
