The miRNAs are then incorporated into RNA-induced silencing complexes where they function either to inhibit translation or to mediate the degradation of their target mRNAs commonly by binding to complementary regions in the 3' untranslated regions (UTRs) [ 2- 4].
These results indicate that suppression is due to direct miR-125b binding to complementary seed sequence in ADAMTS-4 3'-UTR.
miRNAs are a class of small, non-coding RNAs, from 19-24 nt in length, that post-transcriptionally regulate gene expression by binding to complementary regions in, primarily, the 3' untranslated region (3' UTR) of target messenger RNAs.
MicroRNAs (miRNAs), a class of small non-coding RNAs, regulate gene expression post-transcriptionally through binding to complementary regions in the 3′ untranslated regions (3′ UTRs) of target mRNA, which results in mRNA degradation or attenuated translation10,11.
Commonly but not always, an miRNA silences gene expression by binding to complementary mRNA sequences in the 3′-untranslated regions (UTRs) of their target genes.
Micro RNAs control gene expression by binding to complementary sites in the 3′ untranslated regions (3′ UTRs) of target mRNAs, triggering either translational inhibition or mRNA degradation (Baek et al, 2008).
MicroRNAs are small non-coding RNA molecules that regulate mRNA translation and stability by binding to complementary sequences usually within the 3' un-translated region (UTR).
Notably, microRNAs (miRNAs), which comprise one of the most abundant classes of genes regulators [ 7], play important regulatory roles in metazoan animals and plants [ 8] by binding to complementary sequence in the 3 untranslated region (3-UTR) of target mRNAs, leading to cleavage or translational repression [ 2, 9].
They can inhibit the expression of specific messenger RNAs by binding to complementary target sequences located in the 3' untranslated region (3'UTR) [1].
miRNAs are small noncoding RNAs that can silence target mRNAs by binding to complementary sequences in 3' untranslated regions (3'UTR) to induce target mRNA degradation or translational repression [ 16]. miRNAs have been associated with the collagenases and aggrecanase that are stimulated by IL-1β in OA cartilage degradation [ 17- 19].
