Article Title: Modified Polyadenylation-Based RT-qPCR Increases Selectivity of Amplification of 3′-MicroRNA Isoforms

Journal: Frontiers in Genetics

doi: 10.3389/fgene.2018.00011

Forward primer 3′-extension increases selectivity toward short isomiRs. (A) Schematic of the selective amplification of poly-A reversed-transcribed 21 nt (in green) or 24 nt (in red) miR-222-3p isomiRs using a PCR approach with a forward primer of 21 nt comprising a stretch of 4 adenosines in its 3′-end. The 4A stretch creates a structural distortion in the 3′-end of the primer that is not favorable to 5′-3′ extension by Taq polymerase when the primer binds to the 24 nt miRNA variant. (B) Polyadenylated, reverse-transcribed miR-221-3p 24 nt isomiR was amplified with a non-modified 21 nt forward primer (F222-21), or two 21 nt forward primers with 2 or 5 terminal adenosines in their 3′-end (F222-21-2A and F222-21-5A). The amplification values are normalized to the Cq value obtained for the non-modified 21 nt primer, and are displayed as percentages (mean ± SEM is shown). (C) Amplification of the polyadenylated, reverse transcribed synthetic 25 nt RNA#1, which contains a 3′-end with a high proportion of adenosine residues. The amplification values are normalized to the Cq value obtained for the non-modified 25 nt primer, and are displayed as percentages (mean ± SEM is shown). (D) Synthetic miRNA variants of miR-222-3p were analyzed by polyadenylation RT-qPCR with 4A-modified forward primers of different length. (E) Synthetic miRNA variants of miR-222-3p were analyzed by polyadenylation RT-qPCR with 4A-modified forward (F222-21-4A), Taqman stem loop assay (TM-222-21) or miRCURY LNA assay (LNA-222-21), all targeted to the 21 nt isoform. (D,E) The amplification values on the heatmap are normalized per line, to the amplification obtained with the primer targeting the isomiR on this line (D) or the 21 nt isoform (E) . Red = amplified; White = not amplified. The reddest color reflects values of 100% or more. (C–E) The forward primer names start with an “F”, and are ended by the length of the isomiR there are designed to amplify, with “4A” denoting a 4A 3′-terminal stretch. (B–E) Data shown is averaged from two independent RT-qPCR analyses.
