Integrated analysis of long noncoding RNAs and mRNAs reveals their potential roles in the pathogenesis of uterine leiomyomas.

ABSTRACT: Global expression profiling studies showed that miRNAs are aberrantly expressed in uterine leiomyomas (ULMs) and are involved in ULM pathogenesis. Long noncoding RNAs (lncRNAs) are another group of regulatory RNA whose expression and roles in ULMs have not been explored. In this study, we examined the global expressions of lncRNAs and mRNAs in ULMs using microarray and interrogated their interrelationship through co-expression analysis. We found that lncRNAs and mRNAs were dysregulated in ULMs and the degree of dysregulation was positively correlated with tumor size. Further analysis showed that lncRNAs correlate to their cis mRNAs in expression levels depending on genomic locations and orientations. Moreover, we identified several dysregulated pathways that were correlated to dysregulated
