Understanding cooperativity of microRNAs via microRNA association networks

Young-Ji Na, Ju Han Kim
2013 BMC Genomics  
We showed that the secondary structures of pre-miRNAs in cooperatively regulating miRNAs are highly similar.  ...  Sequence and structural similarity analysis within miRNA association network showed that pre-miRNA secondary structure may be involved in the expression of mature miRNA's function.  ...  Although CMMs tend to include miRNA families as shown in Table 3 , structural similarity of pre-miRNAs within CMM cannot be explained by miRNA families because many of them originate from different precursors  ...
