What are super enhancer lncRNAs?
Super-enhancer lncRNA (SE-lncRNAs), emerging as a novel class of master RNA regulators, is a special set of long noncoding RNAs transcribed from super-enhancer genomic loci. SE-lncRNAs, together with super-enhancers, activate the nearby gene expression by mechanisms of transcription factor trapping, chromatin looping, chromatin modification, PolII loading, and release of transcriptional repressor (Fig. 1). Also, SE-lncRNAs are increasingly found to trans-activate target genes [1]. SE-lncRNA have been associated with many human diseases and their expression manifests in profound phenotypic changes [1-3]

Master regulator RNAs in biology and disease
Super-enhancer lncRNAs play master regulatory roles in diverse gene expression programs that ultimately determine the cell types, cell identities, and diseases. For example, SE-lncRNAsCERNA and DRRRNA auto-regulate the master transcription factor MyoD and myogenic genes to turn on myogenesis [2]. Many SE-lncRNAs are intimately involved in cancers. A good example can be CCAT1-L, upstream of MYC gene. It mediates enhancer-promoter loop formation, activates MYC expression and promotes colorectal cancer progression [3].
The super-enhancer lncRNAs, emerged from hidden just recently, are now a scientific gold mine in the research of any fields of biology and disease. Arraystar has developed the SE-lncRNA profiling solution to simultaneously profile SE-lncRNAs, target genes, transcription factors and oncogenes, to accelerate the investigation of SE lncRNAs and the coding genes under their control.

• Gold standard lncRNAs and reliable lncRNAs from Arraystar Premium transcriptome databases are mapped to the super-enhancer loci catalogued in the dbSUPER database. The lncRNAs overlapped with the super-enhancers are identified and annotated as SE-lncRNAs.
• Enhancer-lncRNAs from literature [4, 5], whose genomic loci overlap with the cataloged super-enhancer loci. |
| Super-lncRNAs sources |
Super-lncRNAs are long noncoding RNAs which form RNA:DNA:DNA triplex with multiple anchor DNA sites within the super-enhancers and recruit regulators to the super-enhancers. Super-lncRNAs influence chromatin organization and act as spatial amplifiers for key tissue-specific genes associated with super-enhancers[6]. |
| SE-lncRNA targeted coding genes sources |
The Refseq genes that either overlap with the SE-lncRNA genomic loci or whose transcription start sites (TSS) fall within 50 kb of the SE-lncRNA genomic loci boundaries are collected as SE-lncRNA targeted coding genes. These genes include 3153 transcription factors (TFs) from TF checkpoint database and 1448 cancer genes from Bushman Lab database. |
