miRNAs are short non-protein coding RNAs, being though a crucial regulators of gene expression of up to 90%
of human genes (Friedmann et al., 2009; Guo et al., 2010; Perron and Provost, 2010; Bartel, 2009; Esquela-Kerscher and Slack, 2006; Bartel, 2006; Kozomara and Griffiths-Jones, 2011; Selbach et al., 2008). These tiny RNA molecules tune cell growth, tissue differentiation, cell proliferation, embryonic development, apoptosis and cellular signaling (Gaur et al., 2007; Godlewski et al., 2012; Kim et al., 2010; Cui et al., 2006). Even slight shift in miRNA level could lead to significant changes of transcriptome, and in a result of cell phenotype. In the last decade, over 30 000 mature miRNA sequences were deposited in miRBase (Griffiths-Jones et al., 2006). The function of many of them have been found and anti-miRNA tools, as potential therapy approach have been designed. Despite of an enormous data of miRNA, there are still many questions concerning miRNA function to be solved. Following Francis Crick’s famous statement “If you want to understand function, study structure”, we were looking for structure of mature miRNAs (Belter et al., 2014). |
