  2. IsomiR - Wikipedia

    en.wikipedia.org/wiki/IsomiR

    The functionality of adenylation or uridynilation at the 3'end (3'addition isomiRs) has been related to alterations in the miRNA-3'-UTR stability. [18] Furthermore, differential expression of isomiRs has been detected during development in D. melanogaster and Hippoglossus hippoglossus L., suggesting a biological function. [15] [19]

  3. microRNA - Wikipedia

    en.wikipedia.org/wiki/MicroRNA

    miRNA biogenesis in plants differs from animal biogenesis mainly in the steps of nuclear processing and export. Instead of being cleaved by two different enzymes, once inside and once outside the nucleus, both cleavages of the plant miRNA are performed by a Dicer homolog, called Dicer-like1 (DL1). DL1 is expressed only in the nucleus of plant ...

  4. RNA-induced silencing complex - Wikipedia

    en.wikipedia.org/wiki/RNA-induced_silencing_complex

    The biochemical identification of RISC was conducted by Gregory Hannon and his colleagues at the Cold Spring Harbor Laboratory. [5] This was only a couple of years after the discovery of RNA interference in 1998 by Andrew Fire and Craig Mello, who shared the 2006 Nobel Prize in Physiology or Medicine.

  5. Drosha - Wikipedia

    en.wikipedia.org/wiki/Drosha

    These two proteins homeostatically control miRNA biogenesis by an auto-feedback loop. [16] A 2nt 3' overhang is generated by Drosha in the nucleus recognized by Dicer in the cytoplasm, which couples the upstream and downstream processing events. Pre-miRNA is then further processed by the RNase Dicer into mature miRNAs in the cell cytoplasm.

  6. MicroRNA biosensors - Wikipedia

    en.wikipedia.org/wiki/MicroRNA_Biosensors

    MicroRNA (miRNA) biosensors are analytical devices that involve interactions between the target miRNA strands and recognition element on a detection platform to produce signals that can be measured to indicate levels or the presence of the target miRNA. Research into miRNA biosensors shows shorter readout times, increased sensitivity and ...

  7. Short interspersed nuclear element - Wikipedia

    en.wikipedia.org/wiki/Short_interspersed_nuclear...

    The co-localization of microRNA and protein-coding genes provides a mechanistic foundation by which microRNA regulates gene-expression. Furthermore, Scarpato et al. reveals (as discussed above) that genes predicted to possess short-interspersed nuclear elements (SINEs) through sequence analysis were targeted and hybridized by microRNAs ...

  8. let-7 microRNA family - Wikipedia

    en.wikipedia.org/wiki/Let-7_microRNA_family

    The Let-7 microRNA precursor gives rise to let-7, a microRNA (miRNA) involved in control of stem-cell division and differentiation. [ 1 ] let-7 , short for "lethal-7", was discovered along with the miRNA lin-4 in a study of developmental timing in C. elegans , [ 2 ] making these miRNAs the first ever discovered.

  9. Mirtron - Wikipedia

    en.wikipedia.org/wiki/Mirtron

    [1] [2] These short hairpin introns formed via atypical miRNA biogenesis pathways. [3] [4] Mirtrons arise from the spliced-out introns and are known to function in gene expression. Mirtrons were first identified in Drosophila melanogaster and Caenorhabditis elegans.
