This document is an agenda for a webinar on profiling miRNA expression in cells, formalin-fixed paraffin-embedded (FFPE) tissue samples, and serum. The webinar will provide an introduction to miRNAs and disease, discuss sample preparation options for different sample types, and describe the miScript PCR System for profiling miRNA expression. The speaker, Jonathan Shaffer, will summarize the miScript PCR System and take questions at the end of the webinar.

Sample & Assay Technologies Why quantify miRNA? Virtually every publication includes characterization by quantification. Changes in miRNA can be correlated with gene expression changes in development, differentiation, signal transduction, infection, aging, and disease. Webinar 3: Profiling miRNA expression in cells, FFPE, and serum 5
Sample & Assay Technologies Canonical pathway of miRNA biogenesis Transcribed by RNA polymerase II as a long primary transcript (pri-miRNAs), which may contain more than one miRNA. In the nucleus, pri-miRNAs are processed to hairpin-like pre-miRNAs by RNAse III-like enzyme Drosha. Pre-miRNAs are then exported to the cytosol by exportin 5. In the cytosol, RNAse III-like Dicer processes these precursors to mature miRNAs. These miRNAs are incorporated in RISC. miRNAs with high homology to the target mRNA lead to mRNA cleavage. miRNAs with imperfect base pairing to the target mRNA lead to translational repression and/or mRNA degradation.

miScript PCR Controls Sample & Assay Technologies Strong expression in 100% blood, low expression in serum 100% Blood: CT Mean 100% Serum: CT Mean ∆CT (Serum - Blood) RNU6-2 21.9 34.4 12.5 SNORD61 24.6 35.4 10.8 SNORD68 20.7 33.4 12.7 SNORD96A 23.1 34.1 11.0 SNORD95 21.6 30.9 9.3 SNORD72 27.0 35.1 8.1 Target 36 Blood Percentage (%) Mean CT cel-miR-39 19.24 23.52 50 28 CT Mean: miScript Controls 100 32 CT Mean: cel-miR-39 18.92 24.41 10 18.08 26.37 18.70 30.03 19.91 33.52 0.01 19.42 33.75 0.001 19.67 33.94 0.0001 20 1 0.1 miScript Controls 24 19.03 33.74 16 100 50 10 1 0.1 0.01 0.001 0.0001 Blood Percentage (%) If the mean CT of the miScript PCR Control panel is lower than 32, then you have greater than 0.1% cellular contamination from cells Webinar 3: Profiling miRNA expression in cells, FFPE, and serum 46
Sample & Assay Technologies Data normalization Step 3 Calibrate data of each plate to its RNA Recovery Controls Can only be used if Syn-cel-miR-39 miScript miRNA Mimic is spiked into the sample during RNA preparation Then: If your array is ‘unbiased’ (full miScript PCR Array) Normalize to the CT mean of all expressed targets on plate (OK) OR Normalize to the CT mean of commonly expressed targets on plate (better) Or: If your array is ‘biased’ (small panel of regulated miRNAs) Normalize data to CT of several invariant miRNAs Webinar 3: Profiling miRNA expression in cells, FFPE, and serum 47

Webinar 3: Profiling miRNA expression in cells, FFPE, and serum 5
  • 6. Sample & Assay Technologies Canonical pathway of miRNA biogenesis Transcribed by RNA polymerase II as a long primary transcript (pri-miRNAs), which may contain more than one miRNA. In the nucleus, pri-miRNAs are processed to hairpin-like pre-miRNAs by RNAse III-like enzyme Drosha. Pre-miRNAs are then exported to the cytosol by exportin 5. In the cytosol, RNAse III-like Dicer processes these precursors to mature miRNAs. These miRNAs are incorporated in RISC. miRNAs with high homology to the target mRNA lead to mRNA cleavage. miRNAs with imperfect base pairing to the target mRNA lead to translational repression and/or mRNA degradation.
