    Unveil LncRNA/mRNA Organized R-loop Regulatory Functions

R-loops are RNA:DNA three-stranded hybrid structures formed between LncRNA/mRNA and the template DNA strand by base pairing. They are often located in the CpG islands of the promoters or transcription stop sites and have important biological functions in DNA replication, epigenetic and transcription regulation(Fig.1).

Recent evidence suggests that R-loops are involved in a number of human diseases, including diverse cancers, neurological disorders, and autoimmune diseases.

Arraystar DRIPc-seq (DNA–RNA immunoprecipitation followed by cDNA conversion coupled to high-throughput sequencing) profiles LncRNA/mRNA organized R-loop distribution in the genome(Table 1). The DRIPc-seq, along with LncRNA Array, MeDIP-sequencing, or ChIP-seq, is able to provide valuable functional insights in epigenetic and transcriptional regulation by R-loops.
