Sample & Assay Technologies Canonical pathway of miRNA biogenesis

Webinar 1: Meeting the Challenges of miRNA Research 6

� 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.

Sample & Assay Technologies How do miRNAs interact with mRNAs?

Webinar 1: Meeting the Challenges of miRNA Research 7

Basis of miRNA-mRNA interaction

Seed region: nucleotides 2-8 in 5’ region of miRNA� Most evolutionary conserved miRNA region� Most frequently complementary to target 3’-UTRs� Often sufficient to confer mRNA recognition

Beyond the seed region� 3’ end also contributes (extensive pairing is rare)� Some cases: central 11-12 continuous base pairs

Result of interaction� Suppression of gene expression� Rare cases: increase gene expression

Target Prediction is based on:� Bioinformatics

� Seed region match� Position in 3’ UTR� Cross species conservation� Central sequence homology

� Wet lab research� Empirical evidence from microarrays� Reporter systems

Pitfalls of using prediction algorithms:� Large number of candidate mRNAs for a given

miRNA� May not incorporate all miRNA targeting

possibilities� Different algorithms produce different target

lists� Potential for false positive rate of prediction

Webinar 1: Meeting the Challenges of miRNA Research 11

� Intergenic miRNA genes : either monocistronic or polycistronic with a common promoter

� Intronic miRNA genes : present in the introns of protein coding or noncoding genes, can also be in clusters, transcribed by the host gene promoter

� Exonic miRNAs genes : rare and often overlap an exon and an intron of a noncoding gene

� miRNAs can be transcribed from the negative strand within or near a protein coding gene

Sample & Assay Technologies Unique signatures in human cancer

Webinar 1: Meeting the Challenges of miRNA Research 16

� miRNAs located in genomic regions amplified in cancers (e.g. miR-17-92 cluster) can function as oncogenes, whereas miRNAs located in portions of chromosomes deleted in cance rs (e.g. miR-15a-miR-16-1 cluster) can function as tumor suppressors.

� Abnormal expression of miRNAs has been found in both solid and hematopoietic tumors.

� miRNA expression fingerprints correlate with clinical and biological characteristics of tumors , including tissue type, differentiation, aggression and response to therapy.

In the last 10 years, a substantial number of studi es and reviews have associated the presence of various miRNAs with cell proliferation,

resistance to apoptosis, invasiveness, and differen tiation in cancer cells.

� 5-aza-2’-dC irreversibly inhibits DNA methyltransferase driven DNA methylation reactions by incorporating into DNA and covalently binding to the active site of the DNMT.

� Scatter Plot: Significant differences exist in the mature miRNA expression levels of the two samples that were tested

� 104 miRNAs were strongly up-regulated in 5-aza-2’-dC treated cells, while 30 were strongly down-regulated in 5-aza-2’-dC treated HCT 116 cells.

� Volcano Plot: When a p Value of 0.05 is applied, the expression up-regulation of 89 of the 104 miRNAs is significant, and the expression down-regulation of 21 of the 30 miRNAs is significant
