Co-expression of microrna and mrna in cytogenetically normal acute myeloid leukemia patients [miRNA]


ABSTRACT: The study integrated both miRNA and mRNA profiles to explore novel miRNA-mRNA interactions that affect the regulatory patterns in de novo CN-AML. A total of 637 significant negative correlations (FDR <0.05) were reported. Network analysis revealed a cluster of 12 miRNAs that represents the majority of the mRNA targets. Within the cluster, five miRNAs; miR-495-3p, miR-185-5p, let-7i-5p, miR-409-3p, and miR-127-3p were suggested to play a pivotal role in the regulation of CN-AML as they are associated with negative regulation of myeloid leukocyte differentiation, negative regulation of myeloid cell differentiation, positive regulation of haematopoiesis, and hematopoiesis and its regulation. Three novel interactions in CN-AML were predicted, let-7i-5p:HOXA9, miR-495-3p:PIK3R1 and miR-495-3p:CDK6 which are responsible in regulating myeloid cell differentiation in CN-AML. Overall design: nCounter platform was utilised to profile both miRNA and mRNA using a similar set of patient samples (n = 24). The miRNA-mRNA network was constructed and underlying biological functions of mRNAs were predicted by gene enrichment. Finally, the interaction pairs were assessed by TargetScan.
