Expression of hosting exons for miRNAs. a Schematic illustration of the primers used for amplification. b RT-PCR amplification of intron 2 hosting the miRNAs. Primers in exon 2 and 3 indicated in a were used. c RT-PCR amplification of the coding region of the HT2CR using primers in exon 4 and 6. d RT-PCR amplification of β-Actin, demonstrating equal loading
