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

Londin et al. discovered miRNAs (LmiRNAs) whose properties had been little studied for unknown reasons. In this study, we examined fully complementary interactions of LmiRNAs with mRNAs of human genes. Using the MirTarget program, a significant number of target genes with unique properties of interaction with LmiRNAs were identified. Of 3707 LmiRNAs in the mRNAs of 75 target genes, the sites of fully complementary LmiRNA binding were located in the 5'UTR with a high free energy of interaction. In the mRNAs of 81 target genes, the fully complementary LmiRNA binding sites (BSs) were located in the CDS. Only seven LmiRNAs bound in the 3'UTRs of target genes. The KIFC3, PHF15, RPL15 and SNX11 genes were identified, encoding LmiRNA-5p and LmiRNA-3p, which bind to the mRNAs of these genes. The mRNA of most genes were bound by only one LmiRNA. The BMP8B, BMP8B, FGFRL1 and SDC3 genes were identified, whose mRNAs bound the pair ID00121.5p and ID02992.5p. These results expand our knowledge of LmiRNAs and allow us to recommend these LmiRNAs as diagnostic and therapeutic agents for various diseases.
