m-Meg3 TFO-9 regulates the m-c-Met transcript. (A) Schematic of full-length m-Meg3-1 exon structure showing the TFO-9 coordinates. Full-length m-Meg3-1 is depicted, with exons 1 to 10 numbered (top) and the sequence length in base pairs (bottom). TFO-9, a GA- and GT-rich 16-mer sequence, is shown mapping to the C-terminal portion of exon 10 in m-Meg3-1. TFO-9, spanning bp 1822 to 1838, was predicted by Triplexator to form triplexes with double-stranded DNA. (B) Effect of TFO-9 on the expression of m-Meg3 and m-c-Met transcripts. RNA was isolated at 48 h and 96 h posttransfection from MIN6-4N cells transiently transfected with TFO RNA oligonucleotides. Purified RNA converted to cDNA was subjected to qPCR analyses with primers specific for m-Meg3-1 or m-c-Met. The data represent an average from three independent experiments and multiple technical replicates (mean ± SD) *, P ≤ 0.05.
