We found that the biogenesis of MIR157a and MIR157b, which have smaller loops, was more efficient than that of MIR157c (Figure 4B). Then, we replaced the terminal branched loop of MIR157c by a small loop of 4 nt (Figure 4C , MIR157c- SL).

MicroRNAs (miRNAs) (see Glossary) are essential components of the gene silencing machinery in most eukaryotic organisms. The plant miRNA pathway, both at the biogenesis and silencing levels, differs substantially from its counterpart in mammals. MicroRNAs (miRNAs) are fundamental, sequence-specific regulatory elements of eukaryotic genomes. In plants, these molecules are found amid a maelstrom of heterogeneous, 19–24 nucleotide (nt)-long RNA species called short-interfering RNAs (siRNAs) that mediate endogenous gene silencing at both the transcriptional and posttranscriptional levels. In animals, DEAD-box RNA helicases act as components of the microprocessor complex to regulate miRNA biogenesis (Gregory et al., 2004).

In this thesis, I aimed to Dysregulation of microRNA (miRNA) biogenesis is implicated in cancer development and progression.

MicroRNA (miRNA) biogenesis initiates co-transcriptionally, but how the Microprocessor machinery pinpoints the locations of short precursor miRNA sequences within long flanking regions of the transcript is not known. Here we show that miRNA biogenesis depends on DNA methylation.

2018-08-23 · Biogenesis of miRNAs is subject to complex regulation at both the transcriptional and post-transcriptional levels. As small deviations in miRNA levels can disturb the regulation of different target We found that the biogenesis of MIR157a and MIR157b, which have smaller loops, was more efficient than that of MIR157c (Figure 4B). Then, we replaced the terminal branched loop of MIR157c by a small loop of 4 nt (Figure 4C , MIR157c- SL).
