Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The features of novel miRNAs interaction with mRNA candidate genes having trinucleotide repeats in coding sequences and untranslated regions Abstract.Trinucleotide repeat disorders are a group of predominantly inherited neurological diseases caused by the expansion of repetitive sequences.miRNAs play major roles in transcriptional regulation and are expressed selectively and abundantly in the central nervous system.In the present research, MirTarget program predicted the miRNA-binding sites in mRNAs of genes with trinucleotide repeats.The MirTarget programme determines the following features of binding: the start of the initiation of miRNA binding to mRNAs; the localization of miRNA binding sites in 5'UTRs, CDSs and 3'UTRs; the free energy of binding; and the schemes of nucleotide interactions between miRNAs and mRNAs.In coding sequences the binding sites of ID00372.5p-miR with mRNA of ATXN2, FMN2 and MN1 genes having CAG (Q) repeats show the highest free binding energy.The mRNA of ADRBK1, BRSK2, C11orf87 and FMR1 genes have ID01508.5p-miRbinding sites in 5'UTR with CGG repeated regions.Also, the binding sites of ID00296.3p-miR and ID01702.3p-miR in 5'UTR of BLMH gene interacted with CCG repeats.DMPK gene with CUG repeated regions have ID00522.5p-miRbinding sites in 3'UTR.Based on these results, the interactions of ID00372.5p-miR,ID01508.5p-miR,ID00296.3p-miR,ID01702.3p-miR and ID00522.5p-miR and their target genes ATXN2, FMN2, MN1, ADRBK1, BRSK2, C11orf87, FMR1, BLMH and DMPK can be used for developing methods for diagnosing and therapeutic targets for neurological disorders.
